ABSTRACT
STUDY DESIGN: Retrospective statistical analysis of database. OBJECTIVE: Spinal cord injury (SCI) clinical trials are challenged to enroll participants, and early trial outcomes have often been equivocal. We hypothesized that a specifically designed novel true linear interval-scaled outcome measure targeted to simultaneously track a broad range of SCI will enable more inclusive enrollment of participants and valid comparisons of functional changes after SCI. METHODS: To define a single SCI measurement framework, we used items from existing measures. To evaluate linearity and validity of the measure, we used rigorous psychometric Rasch analysis on two data sets from over 2500 traumatic SCI participants (all levels and severities of SCI) within the EMSCI (European Multicenter study about SCI) database. RESULTS: Volitional performance was found to be the unidimensional construct that would detect and track a treatment effect from a central nervous system-directed therapeutic. Along with early evidence for voluntary neurological control of upper-extremity muscle contractions, volitional performance is best described by goal-directed activities of daily living that are increasingly difficult to re-acquire when activity within more caudal spinal segments is required. Validity of the Spinal Cord Ability Ruler (SCAR) as a linear interval construct was confirmed with Rasch analysis. All measurement items were properly ordered, as well as being precise and stable across clinically relevant groups. Only 5/24 items had some misfit. Targeting was excellent over time after SCI, with few gaps and only modest floor and ceiling effects (3% each). CONCLUSIONS: SCAR is a quantitative linear measure of volitional performance across an inclusive range of tetraplegic and paraplegic SCI.

STUDY DESIGN: Prospective. OBJECTIVES: To test whether provocative stimulation of the testes identifies men with chronic spinal cord injury (SCI), a population in which serum testosterone concentrations are often depressed, possibly due to gonadal dysfunction. To accomplish this objective, conventional and lower than the conventional doses of human chorionic gonadotropin (hCG) were administered. METHODS: Thirty men with chronic SCI (duration of injury >1 year; 18 and 65 years old; 16 eugonadal (>12.1 nmol l-1) and 14 hypogonadal (⩽12.1 nmol l-1)) or able-bodied (AB) men (11 eugonadal and 27 hypogonadal) were recruited for the study. Stimulation tests were performed to quantify testicular responses to the intramuscular administration of hCG at three dose concentrations (ithat is, 400, 2000 and 4000 IU). The hCG was administered on two consecutive days, and blood was collected for serum testosterone in the early morning prior to each of the two injections; subjects returned on day 3 for a final blood sample collection. RESULTS: The average gonadal response in the SCI and AB groups to each dose of hCG was not significantly different in the hypogonadal or eugonadal subjects, with the mean serum testosterone concentrations in all groups demonstrating an adequate response. CONCLUSIONS: This work confirmed the absence of primary testicular dysfunction without additional benefit demonstrated of provocative stimulation of the testes with lower than conventional doses of hCG. Our findings support prior work that suggested a secondary testicular dysfunction that occurs in a majority of those with SCI and depressed serum testosterone concentrations.

Persons with spinal cord injury (SCI) undergo immediate unloading of the skeleton and, as a result, have severe bone loss below the level of lesion associated with increased risk of long-bone fractures. The pattern of bone loss in individuals with SCI differs from other forms of secondary osteoporosis because the skeleton above the level of lesion remains unaffected, while marked bone loss occurs in the regions of neurological impairment. Striking demineralization of the trabecular epiphyses of the distal femur (supracondylar) and proximal tibia occurs, with the knee region being highly vulnerable to fracture because many accidents occur while sitting in a wheelchair, making the knee region the first point of contact to any applied force. To quantify bone mineral density (BMD) at the knee, dual energy x-ray absorptiometry (DXA) and/or computed tomography (CT) bone densitometry are routinely employed in the clinical and research settings. A detailed review of imaging methods to acquire and quantify BMD at the distal femur and proximal tibia has not been performed to date but, if available, would serve as a reference for clinicians and researchers. This article will discuss the risk of fracture at the knee in persons with SCI, imaging methods to acquire and quantify BMD at the distal femur and proximal tibia, and treatment options available for prophylaxis against or reversal of osteoporosis in individuals with SCI.

STUDY DESIGN: Prospective study. OBJECTIVE: To determine the integrity of the hypothalamic-pituitary-testicular axis in healthy men with spinal cord injury (SCI). METHODS: Thirty healthy men with chronic SCI (37±10 years) and thirty-eight able-bodied (AB) controls (36±10 years) participated. Gonadotropin-releasing hormone (GnRH; 100 µg IV) was administered to determine gonadotropin release, and human chorionic gonadotropin (hCG; 4000 IU IM) was administered to determine testosterone (T) secretion. Responses to stimulation were categorized as 'responder' or 'non-responder' by clinical criteria. Single factor ANOVA with repeated measures was performed to identify group differences. RESULTS: The proportion of responders to pituitary GnRH stimulation was similar in the SCI group (22 subjects (73%) for the follicular-stimulating hormone (FSH) and 23 subjects (76%) for the luteinizing hormone (LH) to that of the AB group. The SCI-responder group had an increased FSH response after stimulation compared with the AB-responder group (P<0.05). The SCI-responder group had a greater LH area under the curve to GnRH stimulation than the AB-responder group (P=0.06). The peak FSH response was at 60 min and the peak LH response at 30 min, regardless of group designation. All groups had similar increases in serum T concentration to hCG stimulation. CONCLUSIONS: The pituitary response to stimulation in healthy men with SCI revealed an augmented FSH response; LH response only trended higher. The testicular response to provocative stimulation was similar in hypogonadal and eugondal subjects and in GnRH responders and non-responders. These findings suggest a lack of hypothalamic drive of pituitary gonadotropin release in healthy people with chronic SCI.

STUDY DESIGN: Validation study. OBJECTIVES: To describe the development and validation of a computerized application of the international standards for neurological classification of spinal cord injury (ISNCSCI). SETTING: Data from acute and rehabilitation care. METHODS: The Rick Hansen Institute-ISNCSCI Algorithm (RHI-ISNCSCI Algorithm) was developed based on the 2011 version of the ISNCSCI and the 2013 version of the worksheet. International experts developed the design and logic with a focus on usability and features to standardize the correct classification of challenging cases. A five-phased process was used to develop and validate the algorithm. Discrepancies between the clinician-derived and algorithm-calculated results were reconciled. RESULTS: Phase one of the validation used 48 cases to develop the logic. Phase three used these and 15 additional cases for further logic development to classify cases with 'Not testable' values. For logic testing in phases two and four, 351 and 1998 cases from the Rick Hansen SCI Registry (RHSCIR), respectively, were used. Of 23 and 286 discrepant cases identified in phases two and four, 2 and 6 cases resulted in changes to the algorithm. Cross-validation of the algorithm in phase five using 108 new RHSCIR cases did not identify the need for any further changes, as all discrepancies were due to clinician errors. The web-based application and the algorithm code are freely available at www.isncscialgorithm.com. CONCLUSION: The RHI-ISNCSCI Algorithm provides a standardized method to accurately derive the level and severity of SCI from the raw data of the ISNCSCI examination. The web interface assists in maximizing usability while minimizing the impact of human error in classifying SCI. SPONSORSHIP: This study is sponsored by the Rick Hansen Institute and supported by funding from Health Canada and Western Economic Diversification Canada.

STUDY DESIGN: This is a review article. OBJECTIVES: This study discusses the following: (1) concepts and constraints for the determination of minimal clinically important difference (MCID), (2) the contrasts between MCID and minimal detectable difference (MDD), (3) MCID within the different domains of International Classification of Functioning, disability and health, (4) the roles of clinical investigators and clinical participants in defining MCID and (5) the implementation of MCID in acute versus chronic spinal cord injury (SCI) studies. METHODS: The methods include narrative reviews of SCI outcomes, a 2-day meeting of the authors and statistical methods of analysis representing MDD. RESULTS: The data from SCI study outcomes are dependent on many elements, including the following: the level and severity of SCI, the heterogeneity within each study cohort, the therapeutic target, the nature of the therapy, any confounding influences or comorbidities, the assessment times relative to the date of injury, the outcome measurement instrument and the clinical end-point threshold used to determine a treatment effect. Even if statistically significant differences can be established, this finding does not guarantee that the experimental therapeutic provides a person living with SCI an improved capacity for functional independence and/or an increased quality of life. The MDD statistical concept describes the smallest real change in the specified outcome, beyond measurement error, and it should not be confused with the minimum threshold for demonstrating a clinical benefit or MCID. Unfortunately, MCID and MDD are not uncomplicated estimations; nevertheless, any MCID should exceed the expected MDD plus any probable spontaneous recovery. CONCLUSION: Estimation of an MCID for SCI remains elusive. In the interim, if the target of a therapeutic is the injured spinal cord, it is most desirable that any improvement in neurological status be correlated with a functional (meaningful) benefit.

The International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) is routinely used to determine levels of injury and to classify the severity of the injury. Questions are often posed to the International Standards Committee of the American Spinal Injury Association (ASIA) regarding the classification. The committee felt that disseminating some of the challenging questions posed, as well as the responses, would be of benefit for professionals utilizing the ISNCSCI. Case scenarios that were submitted to the committee are presented with the responses as well as the thought processes considered by the committee members. The importance of this documentation is to clarify some points as well as update the SCI community regarding possible revisions that will be needed in the future based upon some rules that require clarification.

STUDY DESIGN: Randomized controlled trial with single-blinded primary outcome assessment. OBJECTIVES: To determine the efficacy and safety of autologous incubated macrophage treatment for improving neurological outcome in patients with acute, complete spinal cord injury (SCI). SETTING: Six SCI treatment centers in the United States and Israel. METHODS: Participants with traumatic complete SCI between C5 motor and T11 neurological levels who could receive macrophage therapy within 14 days of injury were randomly assigned in a 2:1 ratio to the treatment (autologous incubated macrophages) or control (standard of care) groups. Treatment group participants underwent macrophage injection into the caudal boundary of the SCI. The primary outcome measure was American Spinal Injury Association (ASIA) Impairment Scale (AIS) A-B or better at ≥6 months. Safety was assessed by analysis of adverse events (AEs). RESULTS: Of 43 participants (26 treatment, 17 control) having sufficient data for efficacy analysis, AIS A to B or better conversion was experienced by 7 treatment and 10 control participants; AIS A to C conversion was experienced by 2 treatment and 2 control participants. The primary outcome analysis for subjects with at least 6 months follow-up showed a trend favoring the control group that did not achieve statistical significance (P=0.053). The mean number of AEs reported per participant was not significantly different between the groups (P=0.942). CONCLUSION: The analysis failed to show a significant difference in primary outcome between the two groups. The study results do not support treatment of acute complete SCI with autologous incubated macrophage therapy as specified in this protocol.

Men with spinal cord injury are at an increased risk for secondary medical conditions, including metabolic disorders, accelerated musculoskeletal atrophy, and, for some, hypogonadism, a deficiency, which may further adversely affect metabolism and body composition. A prospective, open label, controlled drug intervention trial was performed to determine whether 12 months of testosterone replacement therapy increases lean tissue mass and resting energy expenditure in hypogonadal males with spinal cord injury. Healthy eugonadal (n = 11) and hypogonadal (n = 11) outpatients with chronic spinal cord injury were enrolled. Hypogonadal subjects received transdermal testosterone (5 or 10 mg) daily for 12 months. Measurements of body composition and resting energy expenditure were obtained at baseline and 12 months. The testosterone replacement therapy group increased lean tissue mass for total body (49.6 ± 7.6 vs. 53.1 ± 6.9 kg; p < 0.0005), trunk (24.1 ± 4.1 vs. 25.8 ± 3.8 kg; p < 0.005), leg (14.5 ± 2.7 vs. 15.8 ±2.6 kg; p = 0.005), and arm (7.6 ± 2.3 vs. 8.0 ± 2.2 kg; p < 0.005) from baseline to month 12. After testosterone replacement therapy, resting energy expenditure (1328 ± 262 vs. 1440 ± 262 kcal/d; p < 0.01) and percent predicted basal energy expenditure (73 ± 9 vs. 79 ± 10%; p < 0.05) were significantly increased. In conclusion, testosterone replacement therapy significantly improved lean tissue mass and energy expenditure in hypogonadal men with spinal cord injury, findings that would be expected to influence the practice of clinical care, if confirmed. Larger, randomized, controlled clinical trials should be performed to confirm and extend our preliminary findings.

STUDY DESIGN: Multi-center, prospective, cohort study. OBJECTIVES: To assess the validity and reliability of the Spinal Cord Independence Measure (SCIM III) in measuring functional ability in persons with spinal cord injury (SCI). SETTING: Inpatient rehabilitation hospitals in the United States (US). METHODS: Functional ability was measured with the SCIM III during the first week of admittance into inpatient acute rehabilitation and within one week of discharge from the same rehabilitation program. Motor and sensory neurologic impairment was measured with the American Spinal Injury Association Impairment Scale. The Functional Independence Measure (FIM), the default functional measure currently used in most US hospitals, was used as a comparison standard for the SCIM III. Statistical analyses were used to test the validity and reliability of the SCIM III. RESULTS: Total agreement between raters was above 70% on most SCIM III tasks and all κ-coefficients were statistically significant (P<0.001). The coefficients of Pearson correlation between the paired raters were above 0.81 and intraclass correlation coefficients were above 0.81. Cronbach's-α was above 0.7, with the exception of the respiration task. The coefficient of Pearson correlation between the FIM and SCIM III was 0.8 (P<0.001). For the respiration and sphincter management subscale, the SCIM III was more responsive to change, than the FIM (P<0.0001). CONCLUSION: Overall, the SCIM III is a reliable and valid measure of functional change in SCI. However, improved scoring instructions and a few modifications to the scoring categories may reduce variability between raters and enhance clinical utility.

STUDY DESIGN: Post hoc analysis from a randomized controlled cellular therapy trial in acute, complete spinal cord injury (SCI). OBJECTIVES: Description and quantitative review of study logistics, referral patterns, current practice patterns and subject demographics. SETTING: Subjects were recruited to one of six international study centers. METHODS: Data are presented from 1816 patients pre-screened, 75 participants screened and 50 randomized. RESULTS: Of the 1816 patients pre-screened, 53.7% did not meet initial study criteria, primarily due to an injury outside the time window (14 days) or failure to meet neurological criteria (complete SCI between C5 motor/C4 sensory and T11). MRIs were obtained on 339 patients; 51.0% were ineligible based on imaging criteria. Of the 75 participants enrolled, 25 failed screening (SF), leaving 50 randomized. The primary reason for SF was based on the neurological exam (51.9%), followed by failure to meet MRI criteria (22.2%). Of the 50 randomized subjects, there were no significant differences in demographics in the active versus control arms. In those participants for whom data was available, 93.8% (45 of 48) of randomized participants received steroids before study entry, whereas 94.0% (47 of 50) had spine surgery before study enrollment. CONCLUSION: The 'funnel effect' (large numbers of potentially eligible participants with a small number enrolled) impacts all trials, but was particularly challenging in this trial due to eligibility criteria and logistics. Data collected may provide information on current practice patterns and the issues encountered and addressed may facilitate design of future trials.

BACKGROUND: Bone mineral density (BMD) of the lumbar spine (L-spine) has been reported to be normal or increased in persons with chronic spinal cord injury (SCI). OBJECTIVE: To determine BMD of the L-spine by dual-energy X-ray absorptiometry (DXA) and quantitative computerized tomography (qCT) in men with chronic SCI compared with able-bodied controls. DESIGN: Cross-sectional, comparative study. SETTING: Clinical research unit, Veterans Affairs Medical Center, Bronx, NY, USA and Kessler Institute of Rehabilitation, West Orange, NJ, USA. METHODS: Measurements of the L-spine were made in 20 men with SCI and compared with 15 able-bodied controls. The DXA images were acquired on a GE Lunar DPX-IQ. The qCT images of the L-spine were acquired on a Picker Q series computerized tomographic scanner. RESULTS: The mean ages for the SCI and control groups were 44+/-13 vs 42+/-9 years, and the duration of injury of the group with SCI was 14+/-11 years. There were no significant differences between the SCI and control groups for L-spine DXA BMD (1.391+/-0.210 vs 1.315+/-0.178 g/m(2)) or for L-spine DXA T-score (1.471+/-1.794 vs 0.782+/-1.481). L-spine qCT BMD was significantly lower in the SCI compared with the control group (1.296+/-0.416 vs 1.572+/-0.382 g/m(2), P=0.05); the T-score approached significance (-1.838+/-1.366 vs -0.963+/-1.227, P=0.059). Subjects with moderate degenerative joint disease (DJD) had significantly higher T-scores by DXA than those without or with mild DJD. CONCLUSION: Individuals with SCI who have moderate to severe DJD may have bone loss of the L-spine that may be underestimated by DXA, reducing awareness of the risk of fracture.

OBJECTIVES: To evaluate the efficacy of acupuncture as a treatment for chronic pain and secondary symptoms after spinal cord injury (SCI) and to identify disease-specific variables associated with response to treatment. DESIGN: A within-subjects design consisting of a 7(1/2)-week no-acupuncture baseline period followed by a 7(1/2)-week treatment period and a follow-up assessment 3 months posttreatment. SETTING: Medical rehabilitation research center. PARTICIPANTS: Twenty-two people with SCI who experienced moderate to severe pain of at least 6 months' duration. INTERVENTION: A course of 15 acupuncture treatments was administered over a 7(1/2)-week period. MAIN OUTCOME MEASURES: Numeric Rating Scale of pain intensity; ratings of interference with activity, individualized symptom rating, Center for Epidemiologic Studies-Depression Scale; Speilberger State Trait Anxiety Inventory, and General Well-Being Schedule. RESULTS: Ten patients (46%) showed improvement in pain intensity and pain sequelae after treatment. However, 6 patients (27%) reported an increase in pain that was still present 3 months after treatment. CONCLUSIONS: About 50% of the study sample reported substantial pain relief after acupuncture treatment, suggesting that acupuncture may provide pain relief for at least a subgroup of individuals with SCI. Future research is needed to determine what part of this effect is because of acupuncture versus nonspecific effects such as placebo effects and regression to the mean.

OBJECTIVE: To determine whether routine catheter changes have any effect on the urinary white blood cell count (WBC) and bacterial culture in asymptomatic individuals with spinal cord injury (SCI) who have indwelling Foley catheters. DESIGN: Prospective case series. SETTING: Urology and SCI outpatient departments of a rehabilitation center. SUBJECTS: Twelve asymptomatic individuals (male and female) with SCI who have chronic indwelling urethral Foley catheters that are changed routinely every month. MAIN OUTCOME MEASURES: Two sets of urinalysis and urinary culture and sensitivity from each individual, one set taken through the Foley catheter before the catheter change and another set after the catheter change. WBC, bacterial identity, and colony count were measured, and the corresponding data were compared. RESULTS: All subjects had pyuria and bacteriuria before and after the catheter change. Analysis of the data showed a statistically significant increase in WBC in the urine after the indwelling Foley catheter was changed (P = .0039). However, bacterial types and corresponding colony counts remained almost completely unchanged. CONCLUSIONS: Routine change of chronic indwelling Foley catheters in asymptomatic individuals with SCI causes a significant rise in the urinary WBC, without altering the bacterial identity or colony count. Pyuria and bacteriuria are prevalent among individuals with SCI (including those who are asymptomatic) with indwelling Foley catheters. This study suggests that urinalysis should be taken before a catheter change.

A tumor that affects the central nervous system can have a dramatic impact on the individual affected, as well as his or her family and friends. The tumor, regardless of extent or location, may affect the physical, social, vocational, and emotional capabilities of the individual. Basic aspects of rehabilitation for patients with tumors affecting the brain and spinal cord are reviewed in this article. The authors have found that the same principles of neurorehabilitation applied to persons with traumatic brain injury, stroke, and traumatic spinal cord injury are equally appropriate for persons with brain and spinal cord tumors. These principles include the prevention of medical complications; the treatment of medical problems such as pain, spasticity, and neuropathic bowel and bladder; and the improvement of patients' mobility and activities of daily living. Rehabilitation specialists can help prevent complications, maximize function, and improve the quality of life for patients with central nervous system tumors.

OBJECTIVE: To determine the effectiveness of acupuncture and Trager Psychophysical Integration (a form of manual therapy) in decreasing chronic shoulder pain in wheelchair users with spinal cord injury (SCI). DESIGN: A prospective clinical trial, with subjects randomized to acupuncture or Trager treatment condition. Subjects served as their own controls by including a 5-week pretreatment baseline period and a 5-week posttreatment follow-up period. SETTING: Rehabilitation hospital research department. PARTICIPANTS: Eighteen subjects with chronic SCI and chronic shoulder pain who used manual wheelchairs as their primary means of mobility. INTERVENTION: Ten acupuncture or 10 Trager treatments over a 5-week period. MAIN OUTCOME MEASURES: Changes in performance-corrected Wheelchair User's Shoulder Pain Index (PC-WUSPI) scores during baseline, treatment, and follow-up periods were assessed by using analysis of variance. RESULTS: The mean PC-WUSPI score +/- standard deviation of the 18 subjects at entry was 48.9 +/- 24.6 (range, 8.0-94). No significant change in mean PC-WUSPI scores occurred during the pretreatment baseline period. Mean PC-WUSPI scores decreased significantly during the treatment period in both the acupuncture (53.4%; 23.3 points) and Trager (53.8%; 21.7 points) treatment groups. The reduced PC-WUSPI scores were maintained in both groups throughout the 5-week posttreatment follow-up period. CONCLUSION: Acupuncture and Trager are both effective treatments for reducing chronic shoulder pain associated with functional activities in persons with SCI.

Autonomic dysreflexia is a syndrome of massive imbalance of reflex sympathetic discharge occurring in patients with spinal cord injury with a lesion above the splanchnic outflow (Thoracic 6). Autonomic dysreflexia is characterized by a sudden and severe rise in blood pressure and is potentially life threatening. Because the onset of this entity is rapid and the potential morbidity is severe, it is important for those caring for spinal cord injury patients to be aware of this syndrome. The paper presents a review of the literature, and familiarizes one with the diagnosis, pathophysiology, and treatment. Two illustrative case reports are also presented.

OBJECTIVE: To assess the electrodiagnostic changes in the lower limbs as measured by nerve conduction studies (NCSs) and electromyography in individuals with chronic complete tetraplegia. DESIGN: Prospective testing of NCS and electromyography. SETTING: Model spinal cord injury rehabilitation center. PARTICIPANTS: Twenty-five individuals with chronic complete tetraplegia without risk factors for peripheral neuropathy or other lower motoneuron disorders. INTERVENTIONS: Nerve conduction parameters recorded from the peroneal, tibial, and sural nerves, and compared with normal values. The presence of spontaneous activity (SA), including fibrillation and positive sharp waves, recorded in 5 muscle groups-2 proximal (vastus medialis, iliopsoas), 2 distal (tibialis anterior, medial gastrocnemius), and L4 lumbar paraspinals. Analysis to see if the presence of SA correlated with the distance of the muscle from the spinal cord or with spasticity (measured by the modified Ashworth scale). MAIN OUTCOME MEASURES: Nerve conduction latencies and velocities; motor and sensory conduction latencies; compound muscle action potential (CMAP) and sensory nerve action potential amplitudes; spontaneous potentials: fibrillation and positive sharp waves; and spasticity. RESULTS: NCS responses were obtained at a decreased frequency relative to able-bodied subjects. Statistically significant results in comparison to normal means included a diminished sural amplitude, and diminished peroneal and tibial CMAP and nerve conduction velocity (p <.0001). SA was recorded in at least 1 of the muscles tested in 92% of subjects, with 72% having SA in more than 1 of the muscles tested affected. A significant difference was seen for SA in the medial gastrocnemius as compared with the iliopsoas (p =.039). No correlation was noted in terms of SA with degree of spasticity. CONCLUSION: A statistically significant difference in NCS responses in the lower limbs in chronic tetraplegia was found relative to normal control values. However, only the frequency of responses elicited and the decreased CMAP of the peroneal nerve are clinically significant. SA was present in many of the lower extremity muscles in the subjects. Predominantly axonal changes were evident in individuals with chronic complete tetraplegia.
