Do not hesitate developed to build upon and extend to discuss active rehabilitation strategies residual functions, including repetitive with your therapist and/or physician. voluntary movement training, strength training, and constraint use therapy (e.g. where the better functioning arm is constrained to force the use of the weaker limb). Some muscle movements, such as hand function or diaphragm contractions (to power breathing) have been enhanced by functional electrical stimulation (FES) of specific nerves or muscles. Thus, there is an emerging consensus that active rehabilitation after SCI is important and effective in preserving body functions, as well as improving the recovery of functional activity after SCI. By active rehabilitation, we mean activities that involve the individual contributing their voluntary efforts to the performance of the task.

The table includes those trials from the search that: 1) are currently or soon-to-be recruiting subjects; 2) are interventional (tested an intervention/treatment) using drugs, cell therapies, surgery, or hypoxia; and 3) targeted neurological or related functional improvement as outcome measures. Interventional clinical trials are routinely registered on based on legal requirements* and because scientific journals may require registration
for publication of trial results. Investigators may choose not to register some early phase
trials and those testing behavioral interventions are sometimes not registered, even
though they may be important and scientifically rigorous studies.
*U.S. Public Law 110-85 requires the registration and reporting of results of "certain applicable
clinical trials," i.e. controlled interventional clinical trials that are subject to FDA regulation and
that involve a Drug or Biologic (other than Phase I investigations), or Device (other than small

So what do we, the authors, say should be the general answers to these questions?
Please see below, but regardless of our opinion, it is a personal decision for which the
individual living with SCI has to weigh the possible benefits against the possible risks in
determining their course of action.
1. Safety
Are there safety risks associated with this experimental treatment? Answer: should be YES; no one can guarantee total safety, but some information should be available about possible risks from either pre-clinical data or earlier Phase clinical studies. Could my condition or my health get worse after this experimental treatment? Answer: should be YES again; if someone states there are little or no risks you should be wary. However, small the chances, there is always the possibility of some problem. If so, can you describe the possible risks associated with this experimental treatment? Answer: the investigator should be able to discuss in detail the possible risks associated with this human study (clinical trial).
2. Possible benefits
Can you describe the possible specific benefits of this experimental treatment? Answer: the investigator should describe a range of possible benefits ranging from very subtle to modest functional improvements. Can you describe the maximum level of recovery I might see after this treatment? Answer: anyone who claims you are going to make a dramatic recovery with the return of almost full function should be avoided, as there is no evidence for any treatment having such striking outcomes, even in preclinical animal studies. c. Can you describe how any potential benefit will be measured? Answer: the investigator should be able to describe a number of different measures that will be used to evaluate your progress after treatment.
3. Clinical trial protocol
a. Is this human study registered as a clinical trial with an appropriate, qualified regulatory body? Answer: should be YES and the investigator should be able to provide you the details immediately. If the answer is vague on this point, you should be concerned (approach with caution). b. Can you describe what clinical trial phase this particular human study falls within (Phase 1, 2, or 3) and what is the emphasis of study for this phase of the trial program? Answer: should be immediate and in as much detail as you want. c. Is there a control group in this study? Answer: should be YES. If not, then this should be a Phase 1 "open label" study (safety only). If not, then this human study is unlikely to be a clinical trial and you should be wary or avoid. However, if this is a study involving people who have lived with a spinal cord injury for many months or years, you serve as your own control. Once again the investigators should be able to provide details immediately. d. Could I be randomly assigned to the control group? Answer: should be YES for Phase 2 and 3 trials, If not, then this is likely not a valid clinical trial. e. Can you tell me how long I will be assessed for any change in outcome? Answer: This may be relatively short (days or weeks) or it could extend for as much as a year or more if the treatment is likely to change the course of your recovery over a prolonged period of time. Depending on the therapeutic intervention, it is possible that you may have to commit more time over the first few weeks and this may include hospital stay as an in-patient. Subsequently, you may be asked to return for assessments at defined times over the following months. Once you agree to participate, you should be willing to complete the full trial protocol, even if you feel you are not benefiting. Participants who withdraw from a study undermine the completion of the trial in a timely fashion and make it difficult to accurately interpret whether the treatment had any benefit. f. Will I be blinded to whether I have received the experimental or control treatment? Answer: If at all physically possible, the answer should be YES. If not, it should be a Phase 1 trial. If not a Phase 1 trial, then you should be wary that this is not a valid clinical trial. Sometimes you cannot help but know what group you are in, but the investigators should ask you not to tell the examiners whether you are in the experimental or control group until the trial is over and the data is analyzed. g. Will the investigators and examiners be blind to what treatment I have received? Answer: this should be a definite YES, unless it is a Phase 1 trial. If not, it is not a valid clinical trial to examine the effectiveness of a treatment and you should be suspicious. 4. Payments and costs a. Do I have to pay for this treatment? Answer: this should be NO. If Yes, then this is not a valid clinical trial. You should be suspicious and probably should avoid the offered treatment. b. Are there any other costs associated with my participation in this study? Answer: you should not have to pay for any procedure specifically related to a clinical trial program, but you, or your health care insurance provider, may have to pay for the current standard of medical care. c. Will my expenses associated with participating in this study be paid (e.g. travel to center for follow-up assessment)? Answer: should be YES. 5. Participation in other trials a. Will my participation in this clinical trial limit my participation in other SCI clinical trials? Answer: could be a possibility. The investigator should be able to outline which type of trials you may be excluded from in the future. For example, it is unlikely that participation in an acute treatment trial would later affect your potential participation to take part in a study at a later (chronic) time point. Nevertheless, the number of inclusion and exclusion criteria for any two trials is difficult to predict unless the protocols are known and compared. b. If I am assigned to the control group and the experimental treatment is subsequently validated as an effective therapy for my type of SCI by this clinical trial program, will I be eligible to receive this treatment later? Answer: could be a possibility, unless your SCI condition changed, or there was a limited time for treatment after SCI, which has now been exceeded in your case. Generally, once an experimental treatment has been approved by a regulatory agency for clinical use, you would be eligible for treatment. 6. Preclinical or prior clinical evidence a. Can you describe the preclinical or prior clinical evidence that demonstrates this experimental treatment is beneficial? Answer: the investigator should be able to outline the previous evidence, including the strengths and limitations of the treatment approach as defined by the preclinical (animal) or studies involving a related human disorder. b. Have these findings been independently replicated? Answer: this could go either way, but there should be some evidence that other researchers have obtained similar results when investigating this therapeutic target or treatments approach. c. Are there any dissenting opinions and do these arguments have some validity for not going forward with this treatment? Answer: the answer here is likely to be a qualified yes, as there are almost always some dissenting opinions about any proposed human treatment. Scientists are usually very critical of each other! The investigator should be able to provide you with a summary of the pros and cons for the treatment, but be wary of any treatment that is claimed to have no limitations. You , your friends and family will undoubtedly use the internet to look up information. We have provided you with a list of some of the reputable websites (Appendix D). If you run into biological or medical terms that you don't understand, we have tried to help by providing a glossary of some of the relevant terms (Appendix C). In any case, you should discuss your concerns and aspirations with your health care providers. 7. Independent assessment of the treatment and investigator a. Can you provide me several names of scientists and clinicians (not involved with this study) who can provide me independent advice about this treatment and your reputation? Answer: should be YES and you should be able to verify the credibility of the study and the credentials of the investigators via the internet.
APPENDIX C: Glossary of selected biomedical terms

NOTE: These terms are commonly used in the discussion of spinal cord injury
(SCI) and/or experimental treatments after SCI. They are provided for your reference, but we could not include every medical or biological term you might encounter.
Action Potential: a short-lasting ( one thousandth of a second) event where the cell membrane potential
(electrical difference across the cell wall) rapidly rises and falls. Action potentials occur in excitable cells, which include neurons, muscle cells, and some endocrine cells. Neuronal action potentials are conducted along an axon and are used to signal activation of that neuron. Action potentials are important for rapid cell-to-cell communication between neurons, especially over long distances, such as between the brain and spinal cord. Over long, large-diameter myelinated axons, action potentials can be conducted as fast as 425 kph or 265 mph (faster than most racing cars). Given the short distances involved in a reflex withdrawal (at most a few feet) it is understandable why it occurs so fast. In muscle cells (fibers) an action potential is the first event leading to contraction of the muscle fiber. Action potentials are also called "nerve impulses"." Activities of Daily Living (ADL): activities involved in self-care, sphincter management and mobility,
such as bathing, dressing, eating, and other skills necessary for independent living. Ambulation: walking, with or without the use of assistive devices such as a walker or crutches.
Apoptosis: see Neuroprotection
ASIA (American Spinal Injury Association):
a North American based society of physicians, surgeons,
scientists and other allied health professionals who treat or investigate SCI. For more information, see ASIA's website: www.asia-spinalinjury.org. ASIA Assessment: see below, International Standards for Neurological Classification of Spinal cord
Injury (ISNCSCI). ASIA Impairment Scale (AIS): (sometimes referred to as ASIA Grades) describes the completeness or
severity of a spinal injury. A booklet and training manual is published and made available by ASIA (see above) AIS A: no motor or sensory function below the neurological level of injury and all the way down to the end of the spinal cord (at the level of S4-S5 sacral segments). Also known as ASIA A AIS B: some sensory function below the neurological level of injury, including S4-5, but no motor function. Also known as ASIA B AIS C: some motor function below the neurological level, but half or more of the key muscles involved have a muscle strength score of less than 3, which is classified as non-functional. Also known as ASIA C AIS D: motor function below the neurological level, but half or more of the key muscles have a muscle grade of 3 or more, which is classified as functional. Also known as ASIA D AIS E: normal motor and sensory function. Also known as ASIA E Assistive, Adaptive, Supportive Devices: a variety of implements or equipment used to aid individuals
in performing tasks or movements. Astrocytes: see Glia.
Autonomic dysreflexia: An autonomic reflex causing a sudden, severe, increase in blood pressure in
response to noxious (painful) or innocuous stimuli, originating below the level of spinal injury. Autonomic dysreflexia is defined by an increase in systolic blood pressure greater than 20 mm above baseline systolic blood pressure. Symptoms can include headache, flushing (blushing), a stuffy nose, sweating above the level of the spinal injury, vasoconstriction (below the level of injury) and irregular beating of the heart. Autonomic dysreflexia can be triggered by an over-full bladder or bowel and is an ongoing medical complication, which occurs most often with an injury at or above the 6th thoracic level of the spinal cord and usually no earlier than 4-6 months after injury. Tetraplegics are more prone to this complication as their autonomic nervous system is unable to oppose the reflex. Balance: the ability of an individual to maintain the body in equilibrium with gravity both statically (e.g.
while stationary) and dynamically (e.g. while moving). Belmont Report: a report created by the former United States Department of Health, Education, and
Welfare (renamed the Department of Health and Human Services) entitled "Ethical Principles and Guidelines for the Protection of Human Subjects of Research." The text is available at: www.hhs.gov/ohrp/humansubjects/guidance/belmont.htm (also see Helsinki Declaration). Properly conducted clinical trials will adhere to the principles and guidelines of the Belmont report. Bias: the tendency of any factors associated with the design, conduct, analysis and interpretation of the
results of a clinical trial to make the estimate of a treatment effect (therapeutic benefit) that differs from its true value (usually assumed to involve an overestimation of benefit and/or an underestimation of risk). Blinded assessments: those evaluations conducted on a clinical trial subject where the evaluator does
not know or ask whether the subject is part of the experimental or control group. Blinded assessments are considered important to reduce any bias in the analysis of the effects of an experimental treatment. There are different levels of blinding: Single-blind studies: either the clinical investigator or the subject, but not both, are blinded. Double blind studies: neither the participating trial subject nor the investigators, institutional staff or sponsoring company are aware of the treatment each subject has received during the trial. Ideal blinding procedures would ensure that the treatments cannot be distinguished by subjective experience, appearance, timing, or delivery method by any of the subjects, investigators, research staff, or clinical staff. Information regarding which treatment was assigned to each individual will typically be held securely by responsible independent members of the study center (or the central data center). It wil not be matched with the data (trial outcomes) until after the study is completed, other than for the purposes of safety monitoring by an independent safety board. also see: Open Label Burst Fracture: is a shattering of the vertebra within the spinal column, usually the ventral round body of
the vertebra (side of the column pointing towards the stomach). The bone shards may compress the spinal cord and there my be a risk of a fragment piercing the spinal cord. Surgeons will often undertake an operation to remove bone fragments and stabilize the spinal column with various rods and screws. The surgery is similar to the procedures performed to fuse (join) to vertebral segments together when a herniated disk is removed. Cauda Equina Syndrome: a progressive neurologic syndrome characterized by lumbar pain, fecal and
urinary incontinence, and possible progressive neurological deficits caused by soft and hard tissue proliferation at the lumbosacral level of the cord, often associated with lumbosacral vertebral or disc damage (also see: Conus Medullaris) Central Nervous System (CNS): The brain and spinal cord. Information coming to the CNS or leaving
the CNS is conducted along nerves of the Peripheral Nervous System (or PNS). also see information under Neuron, Glia, Action Potential, Synapse. Clinical Endpoint: a specified or targeted outcome of a clinical trial, which is based on an evaluation of
the feeling, function or survival of a patient (subject). The results of a clinical trial generally evaluate the statistical significance (and hopefully clinically meaning) of differences between the number of people in the experimental treatment group who reached the pre-determined clinical endpoint as compared to the number of people who achieved the same clinical endpoint from the (placebo) control group. The endpoint may involve a measurement, a change in measurement, or the achievement of at least a certain level of change, pre-identified as a meaningful "response" for the treatment. Clinical Trial: a human research program usually involving both experimental and control subjects to
examine the effectiveness and/or safety of a therapeutic intervention. Prior to issuing a license for a new treatment of a disorder, a typical clinical trial program contains studies at three different stages or phases: Phase 1 is to find out if the treatment is safe and subjects are given the treatment (often at slightly different doses) to see if there are any unexpected, harmful side effects. Phase 2 is the second preliminary study designed to assess whether the treatment stimulates any positive biological activity within the target tissue or is likely to provide a clinically meaningful benefit for the intended body functions in the proposed subject population. Phase 3 is the pivotal trial phase to test the effectiveness and safety of the therapy and involves the largest number of participants at multiple locations. If the treatment demonstrates a clear benefit with no serious side effects (adverse events), then it is eligible to be considered for approval by a national regulatory agency as a clinical treatment for the disorder being studied. Complete and Incomplete SCI: terms used to describe the overal severity of SCI. Technically, SCI is
classified as complete if there is no motor or sensory function preservation in the sacral (most caudal) spinal segments. Thus, incomplete SCI is when there is some preserved motor or sensory function at the lowest sacral spinal level (S4/5). There can be extensive variability in the degree of preserved function after incomplete SCI. Conus Medullaris: is the terminal end of the spinal cord. It occurs near the first lumbar vertebrae (L1).
After the spinal cord terminates, the lumbar and sacral spinal nerves continue as a "freely moving" bundle of nerves within the vertebral canal and are called the cauda equina (literally, horse tail). Control: the comparison group in a clinical trial, which does not receive the experimental treatment being
investigated. The control group may receive a placebo (inactive substance), another treatment, or no treatment other than the current available standard of care and treatment for SCI. The outcomes of the experimental treatment group are compared to the outcomes of the control group. The use of a control group enables researchers to determine whether the new experimental treatment provides a statistically significant and clinically meaningful (functional) benefit for the treatment of SCI. Dermatome: an area of skin innervated by peripheral sensory fibers which travel along a peripheral
nerve that enters the spinal cord at a known level (or segment) of the spinal cord. Dermatomal Maps have been constructed for the human body to evaluate the preservation or loss of sensation throughout different parts of the body. Disk: see Herniated Disk
Dislocation: a disturbance or disarrangement in the normal (overlapping) relationship of the vertebral
bones of the spinal column (for example a facet joint dislocation). Distraction: a term for the act of pul ing apart the overlapping vertebral bones of the spinal column.
Edema: (or oedema) an accumulation of fluid, often occurring as part of the inflammatory process after
Electrophysiological Testing: the process of examining the effects (behavioral or electrical responses)
to electrical, magnetic or natural stimulation of peripheral nerves or the CNS. Electrophysiological testing can be very informative for examining nervous system function, particularly the connectivity across the damaged spinal cord. See also Evoked Potentials. EMG (or Electromyography): the recording of the electrical signals associated with the activity
(contraction) of a muscle. Evoked Potentials: the electrical signals recorded in response to the non-painful electrical or magnetic
stimulation of the brain (via surface electrodes on the scalp) or a peripheral nerve. For example, a Somatosensory Evoked Potential (SEP or SSEP) is the signal recorded from the surface of the scalp overlying the sensory cortex of the brain in response to stimulation of a peripheral nerve (e.g. a leg nerve) and tests the functional ability of CNS pathways to conduct a sensory stimulus through the spinal cord and up to the surface of the brain. A Motor Evoked Potential (MEP) is the signal recorded from a peripheral nerve or muscle in response to an electrical or magnetic stimulation of the motor cortex (via the surface of the scalp) and tests the functional capacity of CNS pathways conducting motor (movement) commands. Frankel Scale: an earlier scale for classifying severity of spinal cord injury that was modified in 1992 to
create the ASIA Impairment Scale or AIS (see above). Functional Electrical Stimulation (FES): treatment through the application of electricity to the peripheral
nerves that arise from the spinal cord. One application would be FES of specific peripheral nerves to train and enable a weak or paralyzed muscle to now make a functional and purposeful movement (e.g. phrenic nerve FES for breathing). Functional Independence Measure (FIM): records the severity of disability in people after a disabling
disorder based on 18 items. Thirteen items define disability in motor functions. Five items define disability in cognitive functions. FIM was not specifically designed for any single disability such as spinal injury. The spinal cord independence measure (SCIM) was designed to specifically record capacities after spinal cord injury (see below). Functional Recovery: an improvement in the ability to perform a physical action, activity, or task. Some
degree of functional recovery is expected to occur spontaneously after injury, but this may be very limited, particularly in sensorimotor complete (AIS-A) SCI. Gait: the manner in which a person walks, characterized by rhythm, cadence, step, stride, and speed.
Glia: usually non-impulse (no action potential) conducting cells of the CNS. Glial cells provide physical
and metabolic support for neurons. Some regulate the internal environment of the brain, especially the fluid surrounding neurons and their synapses (connections), and provide nutrition to nerve cells. Glia have important developmental roles, guiding migration (movement) of neurons to their correct location in early development, and producing molecules that modify the growth of axons and dendrites. These same functions may be important to repair after spinal cord or brain injury. There are 3 main types of glia within the CNS: astrocytes, microglia, and oligodendrocytes. Astrocytes can become inflamed (reactive) after spinal injury, which may be protective by limiting further damage, but this reactive astrogliosis may also block repair. Within the CNS, microglia have similar functions to macrophages within the bloodstream; they protect the brain and spinal cord from foreign substances and cells. They remove dead or dying cells from the CNS. Oligodendrocytes form the myelin sheaths that surround (cover) axons. Myelin speeds the conduction of impulses (action potentials) along an axon, but myelin may also restrict spontaneous growth of axons during adult life (generally a good idea). After a spinal injury, the presence of myelin may interfere with functional repair. Thus temporarily inhibiting myelin function is envisioned as a possible therapeutic target for spinal cord repair. Myelin surrounding the axons of peripheral motor or sensory axons is formed by Schwann cells, which do not inhibit axonal repair after injury. Schwann cell transplants have been thought of as a possible therapeutic strategy to facilitate repair after spinal cord injury. Good Manufacturing Practices (GMP): set of regulations, codes, and guidelines for the manufacture of
drugs (also known as active pharmaceutical ingredients, or APIs) and drug products (known as medicinal products in Europe), cells, medical devices, in vivo and in vitro diagnostic products, and foods. In the United States GMPs are referred to as "cGMPs" or "current Good Manufacturing Practices." GMP is a term that is recognized worldwide for the control and management of manufacturing, as well as quality control testing of pharmaceutical products. Helsinki Declaration: was developed by the World Medical Association and is a set of ethical principles
for the medical community regarding human experimentation. It was originally adopted in June 1964 and has since been amended multiple times. The recommendations concerning the guidance of physicians involved in medical research may be found at www.wma.net/e/policy/b3.htm (also see Belmont Report). Herniated Disk: the protrusion of one or more of the spinal disks, between the vertebra, into the spinal
canal, thereby compressing the spinal cord directly or more often compressing one or more of the incoming or outgoing spinal nerve roots, which can cause numbness, pain, or muscle weakness. ICH: the International Conference on Harmonization of Technical Requirements for Registration of
Pharmaceuticals for Human Use. ICH brings together the regulatory authorities of Europe, Japan and North America with experts from the pharmaceutical industry to discuss scientific and technical aspects of product registration. The purpose is to make recommendations on ways to achieve greater harmonization in the interpretation and application of technical guidelines and requirements for pharmaceutical product registration. The objective of such harmonization is a more economical and ethical use of human, animal and material resources, and the elimination of unnecessary delay in the global development and availability of new medicines whilst maintaining safeguards on quality, safety and efficacy, and regulatory obligations to protect public health (www.ich.org).
Incomplete SCI: see Complete and Incomplete SCI
International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI): A detailed
neurological assessment forms the basis for the International Standards for Neurological and Functional Classification of Spinal Cord Injury (the ASIA International Standards). They are conducted on subjects lying on their backs, and involve a qualitative grading of sensory responses to touch and pin-prick at each of 28 dermatomes along each side of the body and a qualitative grading of the strength of contraction within 10 representative (key) muscles, primarily identified with a specific spinal level, 5 for the upper extremity (C5-T1) and 5 for the lower extremity (L2-S1) on each side of the body. Microglia: see Glia.
Motor Score: based on the ISNCSCI assessment of muscle strength. The motor score is calculated by
assigning to the muscle group, innervated and primarily identified with a specific spinal level, a score between 0 (no detectable contraction) and 5 (active contraction against resistance considered to be normal with a full range of movement about the joint). C5 to T1 and L2 to S1 are tested, giving 10 levels on each side of the body for a possible maximum score of 100. The Lower Extremity Motor Score (LEMS) is a maximal 50-point subset of the ASIA motor score for the representative leg and foot muscles. The Upper Extremity Motor Score (UEMS) is a maximal 50-point subset of the ASIA motor score for the representative arm and hand muscles. Motor Level: defined as the most caudal (lowest) spinal level as indexed by the key muscle group for
that level having a muscle strength of 3/5 or greater while all key muscles above are normal (5/5). Motor-evoked potentials: see Evoked potentials
Myelin: See Glia.
Neurological Level of Spinal Cord Injury: generally the lowest segment of the spinal cord with normal
sensory and motor function on both sides of the body. However, the spinal level at which normal function is found often differs on each side of the body, as wel as in terms of preserved sensory and motor function. Thus, up to four different segments may be identified in determining the motor and sensory level and each of these segments is recorded separately. Note: the level of spinal column (bone) injury may not correlate with the neurological level of spinal cord injury. Neuron: any of the impulse or action potential-conducting cells that constitute the brain, spinal cord, and
peripheral nerves (sometimes called nerve cell). The number of neurons within the CNS is estimated to be about 100 billion. Sensory neurons relay information from sense organs (e.g. within skin and muscle) to the CNS, motor neurons carry impulses from the CNS to muscles and glands, and interneurons transmit impulses between sensory and motor neurons within the CNS (brain and spinal cord). A typical neuron consists of dendrites (fibers that receive stimuli such as synaptic inputs and conduct them toward the cell body), a cell body (a nucleated body that receives input from dendrites), and an axon (a fiber that conducts the nerve impulse from the cell body outward to the axon terminals). Both axons and dendrites may be referred to as nerve fibers. Impulses between neurons are relayed across smal gaps (synapses) by neurotransmitter chemicals released by an axon terminal across the synapse (junction between neurons or between a neuron and an effector cell, such as a muscle fiber). Large axons are insulated by a myelin sheath formed by oligodendrocytes or Schwann cells (see Glia). Neuropathic Pain: usually perceived (felt) as a steady burning sensation or "pins and needles", and/or
as an "electric shock" sensation. "Ordinary" pain stimulates only pain nerves (nociceptive neurons), while neuropathic pain often results from the activation by innocuous (normally non-painful) stimulation such as light touch, warm, or cool stimuli. After SCI, neuropathic pain can occur "above level" in a region of preserved sensation above the level of SCI, "at level" located at the level of SCI and may originate within a nerve root or the spinal cord, or "below level" also known as central pain as this definitely originates within the spinal cord or brain. A characteristic of neuropathic pain is the perception of pain in response to a normal, innocuous stimulus such as a light touch; this is called hypersensitivity or allodynia. Neuroplasticity: see Plasticity
Neuroprotection: the effect of any chemical, biological molecule or medical practice, which limits the
degree of CNS damage resulting from primary mechanical trauma or a degenerative disorder. The majority of spinal cord injuries are the result of mechanical trauma. The neurons directly destroyed by mechanical trauma are probably lost forever, but in most cases the entire cord is not completely damaged by the initial injury. Protecting any surviving cells and neural connections is a high priority target. Similar to when someone bruises the surface of their body, the initially disrupted spinal cells are known to release chemicals that can damage or destroy neighboring healthy neurons. This damage is known as secondary cell death (or apoptosis). Thus many experimental therapies are targeting the biochemical pathways responsible for secondary cell death and trying to limit their activity after spinal cord trauma. One of the limitations may be the need to stop these biochemical reactions within a very short time frame after the primary trauma (perhaps within a few hours). This is a difficult window of opportunity for a therapeutic intervention and also challenges the treatment of other CNS disorder such as traumatic brain injury and stroke. Nutraceutical: Patients have claimed benefits from alternative medical approaches although there is
often limited or no documented scientific evidence to support these claims. Nutraceuticals are non-drug (non-prescription) substances (for example, herbal medicines) that are produced in a purified or extracted form and are administered orally to provide compounds, which are intended to improve health and well-being. These substances are not always control ed or approved by a government health regulatory agency prior to or after sale. If properly labeled, they will usually have a disclaimer stating the product does not guarantee an improved health benefit. Nutraceuticals are often associated with naturopathic or alternative medicine, as is acupuncture. Oedema: See Edema
Oligodendrocyte: See Glia.
Open label: both the researcher and the trial participant know the treatment that the participant is
receiving. See also: Blinded assessments. Pain: See Neuropathic Pain
Paraplegia: the term used to refer to functional loss below the level of the upper extremities, which may
involve loss of motor and/or sensory function within the trunk and/or lower extremities (legs). This implies damage to the spinal cord below the level of T1 and may include damage to the conus medullaris or cauda equina. Peer-reviewed: a scholarly work such as a manuscript or grant application that is read and assessed by
other experts in the same field, to ensure that the author's research and claims have achieved rigorous scientific and statistical standards. Pharmacodynamics: the study of the biochemical and physiological effects of drugs in the body and the
mechanisms of drug action, including the relationship between drug concentration and effect (in brief - what the drug does to the body). Pharmacokinetics: the study of the fate of drugs in the body, with emphasis on the time required for
Absorption, Distribution within body tissues, the mode and extent of Metabolism, or breakdown and the method of Excretion. These 4 outcomes are often noted by the acronym ADME (in brief, what the body does to the drug). Preclinical: the term used to describe scientific experiments conducted prior to a human clinical trial and
may include in vivo studies of animal models of the disorder (e.g. spinal cord injury) or examination of appropriate target cells in an in vitro culture situation. Placebo: an inactive substance or treatment that has the same appearance as the experimental
treatment, but does not confer a physiological (functional) benefit for the disorder being investigated. A placebo effect is a physical or emotional change that is not the result of any physiological action of the treatment. The change may be beneficial in the short term and more accurately reflects the expectations of the participant and/or the expectations of the investigator providing the treatment (also see bias). A placebo drug or "sham" surgery can help distinguish the psychological benefits of an inactive substance from any physiological effects due to the active (experimental) treatment. Plasticity: refers to behavioral changes that occur in the organization of the CNS. Neuroplasticity can be
either positive or negative. For example, the emergence of autonomic dysreflexia or neuropathic pain can be viewed as negative changes that occur after spinal cord injury. Whereas the strengthening of synaptic connections and axonal sprouting after spinal cord injury (SCI) are changes that might lead to the formation of new neural circuits that permit the recovery of some motor function. Experiments have demonstrated improved neuroplasticity with the physical and occupational training found within active rehabilitation programs. A common and surprising consequence of CNS plasticity is that the location of a given function can "move" from one location to another in the brain or spinal cord due to repeated training after traumatic injury. The concept of plasticity can be applied to molecular and functional events. The phenomenon itself is complex and involves many levels of organization, including the expression of adaptive or alternative strategies via the appearance of newly developed neural circuits. The main thing is the adult CNS is not "hard-wired" with fixed and immutable neural connections. We simply do not know all of the conditions that can enhance neural plasticity in the intact or damaged brain and spinal cord. There is evidence that neurogenesis, the formation of new nerve cells, occurs in the adult human brain and spinal cord. Prospective: In terms of a clinical trial, it means to study the effects of an experimental treatment on a
"go-forward" basis, which is the opposite of a retrospective study which looks back historically on the outcomes of a human study. A prospective study is where the methods of data collection and analysis are specified in a protocol before the study is begun (prospective). Patients are subsequently recruited and randomly assigned to receive either the experimental or control treatment and the outcomes are collected and analyzed prospectively (in a go-forward manner). Quadriplegia: see Tetraplegia
Range of Motion: describes the space, distance, or angle through which a person can move a joint or
series of joints in their arms and legs. [p.26] RCT or Randomized Control Trial: a clinical trial in which the subjects enrolled are randomly assigned
to either the experimental treatment arm (group) or control study arm of the trial. It is the preferred clinical trial protocol to be used in all pivotal clinical trial phases (e.g. Phase 3 trials). Well-designed RCT's minimize the influence of variables other than the intervention that might effect trial outcomes. For this reason, they provide the best evidence of efficacy and safety. The most rigorous RCTs utilize a placebo (inactive) control group and blinding (conceal from trial examiners which participants have received active vs. control treatment) to minimize bias in interpretation of results. Regeneration / Repair: terms used to describe mechanisms underlying restoration of function. In the
case of CNS damage such as spinal cord injury, regeneration has been used to describe the regrowth of axons severed during spinal trauma. It was once thought that effective recovery after a cervical cord injury could only be accomplished when injured axons regenerated over long distances to the end of the cord (lumbosacral regions). It is now believed that short distance axonal sprouting across the zone of injury can be equally effective as functional "plasticity" (re-wiring) within the neural circuits below the level of injury can contribute to recovery. Repair is a more inclusive term and includes many processes that could contribute to recovery of function, including: "drugs" that stimulate axonal sprouting or the generation of new replacement cells from within the cord, the transplantation of "stem" cells, as well as beneficial reactions from CNS glia after spinal cord damage and implanted bio-compatible scaffolds. Secondary cell death: see Neuroprotection
Sensory Score: based on the ISNCSCI assessment of the patient's perception of sensation from the skin
of the body. The sensory score is calculated by testing a point on the (skin surface) dermatome associated with each spinal level from C2 to S4-5. This is done for both light touch and pinprick sensation and in comparison with sensations perceived from the skin above the level of spinal cord injury, such as the face. Each point is assigned a score from 0 (absent sensation) through 1 (impaired or abnormal sensation) to 2 (normal sensation). This gives a possible maximum score of 56 on each side, for a maximum total of 112 each for light touch and pinprick. Sensory Level: is defined as the spinal segment corresponding with the most caudal dermatome having
a normal score of 2/2 for both pinprick and light touch. [p.11] Schwann Cell: See Glia. [p.25]
Spinal Cord Independence Measure: (or SCIM) A scale for assessing function and activities of daily life
that appears to be more sensitive and accurate for assessing SCI than the Functional Independence Measure (FIM). SCIM has now gone through a few iterations (currently in version 3). The SCIM is a 100-point disability scale developed specifically for SCI with emphasis on 17 activities associated with: 1. Self-care (feeding, bathing, dressing, grooming) max. = 20 points 2. Respiration and sphincter management (breathing, bladder, bowel, use of toilet) max. = 40 points (clinically weighted) 3. Mobility (in bed, transfers, indoors and outdoors, wheelchair, walking) max. = 40 points. Sham operative procedure: a surgical procedure in which the subject is operated on but does not
receive the experimental intervention. This is the equivalent of a drug placebo treatment. Somatosensory evoked potentials: see Evoked potentials
Spasticity: involuntary increase in muscle tone (tension) that occurs following damage to the brain or
spinal cord, causing the muscles to resist being moved. Characteristics may include increase in deep tendon reflexes, resistance to passive stretch, clasp knife phenomenon, and clonus (limb movements characterized by rapid alternating contractions and relaxations of muscles). Clonus is frequently observed after SCI when the individual also has spasticity. A more scientific definition of spasticity is a velocity-dependent, increased resistance to passive muscle stretch. In other words, when a spastic muscle is stretched, it is harder to move the muscle than normal, and the faster the muscle is stretched, the harder the muscle is to move. Stem or Progenitor Cells: Cel transplantation has been extensively reported by the popular media as a
universal treatment for all manner of il ness or injury. While tremendous progress has been achieved for certain simple tissues and their associated disorders and diseases, including bone, muscle and blood, the routine use of cell transplants for CNS disorders is still in early development. Unfortunately, because generating cells for transplantation is a relatively easy procedure, several unscrupulous clinics have been offering surgical treatments with cell injections, even though there is no validated evidence for benefits from these procedures. As can be appreciated the CNS is the most complex organ of the body containing thousands of uniquely identifiable cell types. Most transplanted cells are likely to only differentiate (change into) a few types of adult neurons and glia. Thus what type of cells and how many cells should be transplanted are still unanswered questions. When do we transplant after injury, where do we transplant and how do we protect the transplanted cells from being rejected by the host CNS. Every simple answer triggers dozens of further questions. What follows is a very short and incomplete explanation (for further details, please consult documents available on the International Spinal Cord Society (ISCoS) website (www.iscos.org.uk) ‘True' stem cells have the potential to self-renew indefinitely and differentiate (develop) into numerous types of cells. In practice most cell transplants do not involve ‘true' stem cells. In reality, they are progenitor cells, which come from stem cells. However the term stem cell has entered popular folklore and is commonly used for all transplanted cells. Progenitor cells have less plasticity than ‘true' stem cells and a more limited capacity to differentiate. Once CNS cell transplant procedures have been developed and refined, the potential benefits of stem cells are numerous and include: replace lost cells due to injury or disease, provide substrate or scaffold for axonal outgrowth to create novel neural connections, limit detrimental inflammation and reduce secondary cell damage, promote blood vessel formation, and/or release beneficial cytokines and growth factors. Of course, with any emerging technological advance there a number of unknowns or concerns with a premature application of cell transplants after spinal cord injury and these include: a very incomplete understanding of the benefits and risks in preclinical animal studies, poorly defined cell products (some with no GMP protocols or standards), additional damage to cord if cells have to be injected directly into the spinal cord tissue, stimulation of neuropathic pain, and/or causing the formation of cancerous tumors since some stem or progenitor cells can rapidly divide. Surrogate endpoints: A measurement of an expected biologic activity from the experimental drug or cell
transplant that substitutes for the clinical (functional) endpoint. A surrogate endpoint (outcome) may predict a patient's final clinical outcome. A surrogate marker (measure) may indicate whether a drug is effective without having to wait for the longer-term functional clinical endpoints being achieved. The identification of an accurate surrogate measure or marker can reduce the time required in an early clinical trial phase to show a possible benefit. Surrogate endpoints can and have been used in Phase 2 clinical trials. Synapse: the cell membrane of the signal-passing neuron (presynaptic neuron) comes into close
apposition with the membrane of the target (postsynaptic) neuron. Both the presynaptic and postsynaptic sites contain receptors and molecular machinery necessary for synaptic communication between the two neurons. the presynaptic part belongs to an axon terminal, while the postsynaptic element is usually a dendrite or soma of the second neuron. It should be noted that many neurons can receive and integrate inputs from thousands of presynaptic neurons and project to several hundred other neurons. In short, every neuron is presynaptic to some neurons and postsynaptic to other neurons. In a chemical synapse, the presynaptic neuron releases a chemical called a neurotransmitter that binds to receptors located in the postsynaptic cell, usually embedded in the plasma (cell) membrane. The neurotransmitter may activate a receptor-ion channel complex directly or an indirect second messenger pathway that either excites or inhibits the postsynaptic neuron. The number of neurons is estimated to be 100 bil ion and the number of synaptic connections in the average adult brain is truly astronomical and defies comprehension (approximately 250-500 trillion). Tetraplegia: (also known as quadriplegia) refers to loss of motor and/or sensory function in all four limbs
due to spinal cord damage, with impairment of the upper extremities as well as trunk, legs and pelvic organs. This implies damage to the cervical spinal cord (at or above the T1 level). Technically tetraplegia is the more correct term, because "tetra", like "plegia", has a Greek root, whereas "quadra" has a Latin root and in classic naming terminology you do not mix Latin with Greek words! Zone of Partial Preservation (ZPP): only used when SCI is complete and refers to those segments
below the neurological level of injury where there is some preservation of impaired motor or sensory function (usually, but not always, within a few segments of the neurological level). APPENDIX D: Selected websites (listed alphabetically)
