Abstract
BACKGROUND/OBJECTIVE The end goal of clinical care and clinical research involving spinal cord injury (SCI) is to improve the overall ability of persons living with SCI to function on a daily basis. Neurologic recovery does not always translate into functional recovery. Thus, sensitive outcome measures designed to assess functional status relevant to SCI are important to develop. METHOD Evaluation of currently available SCI functional outcome measures by a multinational work group. RESULTS The 4 measures that fit the prespecified inclusion criteria were the Modified Barthel Index (MBI), the Functional Independence Measure (FIM), the Quadriplegia Index of Function (QIF), and the Spinal Cord Independence Measure (SCIM). The MBI and the QIF were found to have minimal evidence for validity, whereas the FIM and the SCIM were found to be reliable and valid. The MBI has little clinical utility for use in the SCI population. Likewise, the FIM applies mainly when measuring burden of care, which is not necessarily a reflection of functional recovery. The QIF is useful for measuring functional recovery but only in a subpopulation of people with SCI, and substantial validity data are still required. The SCIM is the only functional recovery outcome measure designed specifically for SCI. CONCLUSIONS The multinational work group recommends that the latest version of the SCIM (SCIM III) continue to be refined and validated and subsequently implemented worldwide as the primary functional recovery outcome measure for SCI. The QIF may continue to be developed and validated for use as a supplemental tool for the nonambulatory tetraplegic population.

Abstract
OBJECTIVE To evaluate an implanted neuroprosthesis that allows tetraplegic users to control grasp and release in 1 hand. DESIGN Multicenter cohort trial with at least 3 years of follow-up. Function for each participant was compared before and after implantation, and with and without the neuroprosthesis activated. SETTING Tertiary spinal cord injury (SCI) care centers, 8 in the United States, 1 in the United Kingdom, and 1 in Australia. PARTICIPANTS Fifty-one tetraplegic adults with C5 or C6 SCIs. INTERVENTION An implanted neuroprosthetic system, in which electric stimulation of the grasping muscles of 1 arm are controlled by using contralateral shoulder movements, and concurrent tendon transfer surgery. Assessed participants' ability to grasp, move, and release standardized objects; degree of assistance required to perform activities of daily living (ADLs), device usage; and user satisfaction. MAIN OUTCOME MEASURES Pinch force; grasp and release tests; ADL abilities test and ADL assessment test; and user satisfaction survey. RESULTS Pinch force was significantly greater with the neuroprosthesis in all available 50 participants, and grasp-release abilities were improved in 49. All tested participants (49/49) were more independent in performing ADLs with the neuroprosthesis than they were without it. Home use of the device for regular function and exercise was reported by over 90% of the participants, and satisfaction with the neuroprosthesis was high. CONCLUSIONS The grasping ability provided by the neuroprosthesis is substantial and lasting. The neuroprosthesis is safe, well accepted by users, and offers improved independence for a population without comparable alternatives.

Abstract
STUDY DESIGN Review by the spinal cord outcomes partnership endeavor (SCOPE), which is a broad-based international consortium of scientists and clinical researchers representing academic institutions, industry, government agencies, not-for-profit organizations and foundations. OBJECTIVES Assessment of current and evolving tools for evaluating human spinal cord injury (SCI) outcomes for both clinical diagnosis and clinical research studies. METHODS a framework for the appraisal of evidence of metric properties was used to examine outcome tools or tests for accuracy, sensitivity, reliability and validity for human SCI. RESULTS Imaging, neurological, functional, autonomic, sexual health, bladder/bowel, pain and psychosocial tools were evaluated. Several specific tools for human SCI studies have or are being developed to allow the more accurate determination for a clinically meaningful benefit (improvement in functional outcome or quality of life) being achieved as a result of a therapeutic intervention. CONCLUSION Significant progress has been made, but further validation studies are required to identify the most appropriate tools for specific targets in a human SCI study or clinical trial.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVES To report the feasibility, safety, and utility of vertebral body stapling without fusion as an alternative treatment for adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA The success rate of brace treatment of adolescent idiopathic scoliosis ranges from 50% to 82%. However, poor self-image and brace compliance are issues for the patient. An alternative method of treatment such as a motion-preserving vertebral body stapling to provide curve stability would be desirable. METHODS We retrospectively reviewed 21 patients (27 curves) with adolescent idiopathic scoliosis treated with vertebral body stapling. Patients were immature as defined by Risser sign <or=2. RESULTS The concept of vertebral body stapling of the convex side of a patient with adolescent idiopathic scoliosis is feasible. The procedure was safe, with no major complications and three minor complications. One patient had an intraoperative segmental vein bleed resulting in an increased estimated blood loss of 1500 cc as compared to the average estimated blood loss of 247 cc for all patients. One patient had a chylothorax and one pancreatitis. No patient has had a staple dislodge or move during the follow-up period (mean 11 months, range 3-36 months), and no adverse effects specifically from the staples have been identified. Utility (defined as curve stability) was evaluated in 10 patients with stapling with greater than 1-year follow-up (mean 22.6 months) and preoperative curve <50 degrees. Progression of >or=6 degrees or beyond 50 degrees was considered a failure of treatment. Of these 10 patients, 6 (60%) remained stable or improved and 4 (40%) progressed. One of 10 (10%) in the stapling group had progressed beyond 50 degrees and went on to fusion. Six patients required stapling of a second curve, three as part of the primary surgery, and three as a second stage, because a second untreated curve progressed. The results need to be considered with caution, as the follow-up is still short. CONCLUSIONS The data demonstrate that vertebral body stapling for the treatment of scoliosis in the adolescent was feasible and safe in this group of 21 patients. In the short-term, stapling appears to have utility in stabilizing curves of progressive adolescent idiopathic scoliosis.

Abstract
Thirty-nine consecutive patients have had vertebral body stapling of 52 curves (26 patients with one curve stapled and 13 with two). For the group with patients who were 8 years or older with less than 50 degrees preoperative curve and a minimum 1-year followup, coronal curve stability was 87% when defined by progression less than or equal to 10 degrees . Fusion was necessary in two patients. No curves less than 30 degrees at the time of stapling progressed greater than or equal to 10 degrees . Major complications occurred in one patient (2.6%, diaphragmatic hernia) and minor complications occurred in five patients (13%). Further followup of the patient cohort and further research into efficacy and indications are warranted.

Abstract
STUDY DESIGN Intra-rater reliability study, cross-sectional design. OBJECTIVES To determine reliability of the International Standards for Neurological Classification of Spinal Cord Injury (ISCSCI) motor and sensory exam in children. SETTING Nonprofit pediatric hospital. METHODS In all, 74 subjects had two trials of the motor and sensory exams. Intraclass correlation coefficients (ICC), 95% confidence intervals (CI) were generated for total motor (TM), pin prick (PP) and light touch (LT) scores for the entire sample, four age groups, severity and type of injury. Coefficients >0.90=high reliability; 0.75-0.90=moderate reliability and <0.75=inadequate reliability. RESULTS Children <four years (N=7) were unable to participate in the exams. TM ICC, CI=0.888, 0.821-0.93 (N=73); PP ICC, CI=0.975, 0.96-0.98 (N=67) and LT ICC, CI=0.974, 0.974-0.985 (N=68). When age was considered, 4-5 year: TM ICC, CI=0.917, 0.69-0.98 (N=11), PP=0.912, 0.49-0.985 (N=7), LT=0.948, 0.63-0.993 (N=6); for 6-11 year: TM ICC, CI=0.711, 0.226-0.892 (N=18), PP=0.952, 0.867-0.983 (M=17), LT=0.952, 0.867-0.983 (N=17); for 12-15 year: TM ICC, CI=0.893, 0.723-0.959 (N=19), PP=0.982, 0.953-0.993 (N=19), LT=0.982, 0.953-0.993 (N=19); for 16-21 year: TM ICC, CI=0.912, 0.80-0.961 (N=25), PP=0.98, 0.954-0.991 (N=25), LT=0.98, 0.954-0.991 (N=25). ICC for severity and type of injury >0.90 except for TM in complete injuries (0.808). CONCLUSION The ISCSCI exams may have poor utility in children under 4 years. While reliability values for the motor and sensory exams met or exceeded recommended values, wide CI suggest poor precision of the motor exam in children under 15 years of age and sensory exams in children under 5 years.

Abstract
OBJECTIVE To evaluate the accuracy and agreement of International Standards for Neurological Classification of Spinal Cord Injury (ISCSCI) classification and to determine the effectiveness of formal training for pediatric clinicians. STUDY POPULATION Participants (N = 28) in a formal 90-minute classification training session. OUTCOME MEASURE Pre/post-training examination of 10 case examples of a variety of neurological classifications. RESULTS Regardless of years of experience with the ISCSCI, a statistically significant improvement (P < 0.05) in classification was achieved after formal training. Before training, 27% (539 of 1,960) of the questions were answered incorrectly. After training, the percentage of incorrect classifications decreased to 11% (198 of 1,960) incorrect (P < 0.05). After training, the percentage of incorrect motor level classifications decreased by 23% (42% to 19% incorrect; P< 0.05). Post-training improvements were also demonstrated (P< 0.05) in classifying sensory levels (9% to 3% incorrect), neurological levels (31% to 6% incorrect), and severity of injury (9% to 0% incorrect). After training, reductions in classification errors (P < 0.05) were demonstrated in American Spinal Injury Association (ASIA) Impairment Scale (AIS) A (from 20% to 7%), B (50% to 11%), C (71% to 46%), and D (63% to 16%). CONCLUSIONS This study demonstrated the benefits of formal, standardized training for accurate classification of the ISCSCI. Effective training programs must emphasize the guidelines and decision algorithms used to determine motor level and ASIA AIS designations because these remained problematic after training and are often a concern of patients/parents and are primary endpoints in clinical trials for neurological recovery.

Abstract
PURPOSE The purpose of this study was to evaluate and compare the deltoid to triceps and biceps to triceps transfers for restoration of elbow extension in young persons with tetraplegia. METHODS This was a prospective randomized study. Sixteen arms of 9 subjects between 8 and 20 years of age with cervical-level spinal cord injuries were assigned randomly to undergo either a deltoid to triceps transfer or a biceps to triceps transfer. All arms were followed-up prospectively for at least 2 years after surgery. RESULTS Elbow extension was restored in 8 arms via the deltoid and in 8 arms via the biceps transfers. At the 24-month follow-up evaluation 7 of the 8 biceps transfers produced antigravity strength (grade 3 or better); in contrast only one arm with the deltoid transfer was able to extend against gravity. There was a considerable but subclinical loss (no subject appreciated any functional deficit) of elbow flexion torque after both transfers. Three months after surgery the deltoid group showed a 51% loss of elbow flexion torque and the biceps group showed a 52% loss of elbow flexion torque. By 24 months after surgery both groups improved but still showed a loss of flexion torque (deltoid 32%, biceps 47%). After gaining elbow extension the subjects in both groups rated the performance of most activities of daily living (ADL) and all self-selected activities as better, as measured on the Modified University of Minnesota Tendon Transfer Functional Improvement Questionnaire and the Canadian Occupational Performance Measure, respectively. Likewise all subjects were more satisfied with performance of their goals after undergoing elbow extension reconstruction. CONCLUSIONS This study showed the benefits of restoring elbow extension in persons with tetraplegia and provided support for the biceps transfer as an alternative to the deltoid to triceps transfer in individuals with good brachialis and supinator strength.

Abstract
PURPOSE To evaluate the lower motor neuron (LMN) integrity of upper extremity muscles of persons with high tetraplegia (C1-C4) in order to determine muscles available for stimulation. METHODS Fourteen subjects (23 arms) were evaluated for LMN integrity. Muscles that elicited a functional response (grade 3 or better) to surface electrical stimulation were considered to have intact LMN and good candidates for FES. Strength-duration (S-D) curves were generated on muscles that showed weak (less than grade 3) or no response to surface stimulation. Muscles were considered denervated if S-D curves were discontinuous or depicted steep, increasing amplitude for pulse durations greater than 1 m. RESULTS Muscles for grasp and release had intact LMN in 19 of 23 (83%) arms. The wrist extensors and flexors and pronator were excitable in 17 (74%), 20 (87%) and 19 (83%) arms, respectively. The supinator demonstrated LMN lesion in 80% of the arms. Over 90% of the biceps muscles were unresponsive to electrical stimulation and 85% and 87% of the deltoid and supraspinatus muscles, respectively, were not electrically excitable. The latissimus dorsi and triceps muscles were typically innervated (78% and 91%, respectively) and slightly more than half (52%) of the pectoralis major muscles were excitable. CONCLUSION These data suggest that application of FES in high tetraplegia for hand and arm function would require augmentation because of the inability to stimulate the elbow flexors, deltoid and rotator cuff muscles. These data also show that several paralyzed proximal muscles with intact LMN that have been historically transferred to address shoulder paralysis in other patient populations are available for transfer and stimulation in the population with high level spinal injuries.

Abstract
STUDY DESIGN Postintervention. OBJECTIVES To determine the effectiveness of the Praxis multifunctional implantable functional electrical stimulation (FES) system (Neopraxis Pty. Ltd, Lane Cove, NSW, Australia) to provide standing and stepping ability and bladder and bowel management for individuals with motor complete thoracic level spinal cord injuries (SCI). SETTING Pediatric orthopedic hospital specializing in SCI. SUBJECTS Three males, ages 17 and 21 years, with motor-complete thoracic level SCI and intact lower motor neurons to the muscles targeted for stimulation. METHODS Each subject was successfully implanted with the Praxis FES system. All three subjects received electrodes for upright mobility and the first two subjects received additional electrodes for stimulated bladder and bowel management. Following training, subjects were evaluated in their ability to use FES for nine mobility activities. Acute and chronic experiments of the effect of stimulation on bowel and bladder function were also performed. RESULTS All three subjects could independently stand up from the wheelchair and could walk at least 6 m using a swing through gait pattern. Two subjects were able to independently perform swing through gait for 6 min and one subject was able to independently ascend and descend stairs. Suppression of reflex bladder contractions by neuromodulation (subject 1) and stimulated contractions of the rectum (subject 2) were observed in acute experiments. When stimulation was applied over the course of several weeks, a positive effect on bowel function was measured. Stimulated bladder contractions were not achieved. CONCLUSION The feasibility of using the Praxis FES system for upright mobility and aiding aspects of bladder and bowel function was demonstrated with three subjects with thoracic level SCI.

Abstract
BACKGROUND AND PURPOSE Recent studies suggest that pediatric subjects as old as 8-years-of-age may have difficulty with the ISNCSCI examinations. Our aim was to investigate DTI parameters of healthy spinal cord in children with noncervical IS for comparison with children with SCI and to prospectively evaluate reliability measures of DTI and to correlate the measures obtained in children with SCI with the ISNCSCI. MATERIALS AND METHODS Five controls with thoracic and lumbar IS and 5 children with cervical SCI were imaged twice by using a single-shot echo-planar diffusion-weighted sequence. Axial imaging was performed to cover the entire cervical spinal cord in controls. For the SCI subjects, 2 vertebral bodies above and below the injury were imaged. FA and D values were obtained at different levels of the cervical spinal cord. All subjects with SCI had undergone ISNCSCI clinical examinations. Statistical analysis was performed to access differences of the DTI indices between the controls and SCI subjects, reproducibility measurements, and correlations between DTI and ISNCSCI. RESULTS Subjects with SCI showed reduced FA and increased D values compared with controls. Test-retest reproducibility showed good ICC coefficients in all the DTI index values among controls (≥0.9), while the SCI group showed moderate ICC (≥0.77). There were statistically significant correlations between the various DTI indices and ISNCSCI scores. CONCLUSIONS Preliminary DTI indices in children were determined and showed good reproducibility. Reduced FA and increased D values were seen in children with SCI in comparison with controls and showed good clinical correlation with ISNCSCI examinations.

Abstract
OBJECTIVE To study the utility and functional benefits of an implanted functional electrical stimulation (FES) system for hand grasp and release in adolescents with tetraplegia secondary to spinal cord injuries. DESIGN Intervention study with before-after trial measurement with each subject as his or her own control. SETTING Nonprofit pediatric orthopedic rehabilitation facility specializing in spinal cord injury. PARTICIPANTS A convenience sample of five adolescents between 16 and 18 years of age with C5 or C6 level tetraplegia at least 1 year after traumatic spinal cord injury. Key muscles for palmar and lateral grasp and release were excitable by electrical stimulation. INTERVENTIONS A multichannel stimulator/receiver and eight electrodes were surgically implanted to provide stimulated palmar and lateral grasp and release. In conjunction with implantation of the FES hand system, surgical reconstruction in the form of tendon transfers, tendon lengthenings and releases, and joint arthrodeses was performed to augment stimulated hand function. Rehabilitation of the tendon transfers and training in the use of the FES hand system were provided. MAIN OUTCOME MEASURES Measurements of pinch and grasp force, the Grasp and Release Test (GRT), and an assessment of six activities of daily living (ADL) were administered before implantation of the FES hand system and at regular follow-up intervals. Results of the stimulated response of individual muscles and surgical reconstruction were evaluated using standard and stimulated muscle testing techniques and standard assessment of joint range of motion. All subjects completed followup testing. RESULTS Lateral and palmar forces were significantly greater than baseline forces (p = .043). Heavy objects on the GRT could only be manipulated with FES, and FES increased the level of independence in 25 of 30 ADL comparisons (5 subjects, 6 activities) as compared to baseline. After training, FES was preferred in 21 of 30 comparisons over the typical means of task completion. Of the 40 electrodes implanted, 37 continue to provide excellent stimulated responses and all of the implanted stimulators have functioned without problems. The surgical reconstruction procedures greatly enhanced FES hand function by either expanding the workspace in which to utilize FES (deltoid to triceps transfer), stabilizing the wrist (brachioradialis to wrist extensor transfer), or stabilizing joints (intrinsic tenodesis transfer, FPL split transfer). CONCLUSION For five adolescents with tetraplegia, the combination of FES and surgical reconstruction provided active palmar and lateral grasp and release. Laboratory-based assessments demonstrated that the FES system increased pinch force, improved the manipulation of objects, and typically increased independence in six standard ADL as compared to pre-FES hand function. The study also showed that the five adolescents generally preferred FES for most of the ADL tested. Data on the benefits of the implanted FES hand system outside of the laboratory are needed to understand the full potential of FES.

Abstract
This article briefly discusses several measurement tools for evaluating the upper limb of persons with tetraplegia. Muscle strength testing and electrodiagnostics are discussed as they relate to technique and usefulness for clinical trials. Standardized measures of hand function are reviewed; their limitations for clinical trials during acute spinal cord injury (SCI) care are acknowledged and their strengths for interventional studies and clinical trials during chronic phases of SCI care are defined. Recommendations are set forth for incorporating the International Classification for Surgery of the Hand in Tetraplegia motor and sensory examinations as adjuncts to the International Standards for Neurological Classification of SCI motor and sensory examinations and for further developing electrodiagnostic techniques as measurement tools for acute clinical trials. The Grasp and Release Test is described and recommended for clinical trials involving persons in the chronic stages of SCI. Lastly, we note that much work remains in the development, validation, and clinical deployment of an assessment of upper-limb function in SCI.

Abstract
The application of functional electrical stimulation (FES) to provide upper extremity function for individuals with C4 tetraplegia is under investigation. In this study, a FES system was designed that allowed one individual with complete C4 tetraplegia to coordinate stimulated lateral or palmar prehension with stimulated arm movements using contralateral shoulder position. The system consisted of percutaneous intramuscular electrodes implanted to muscles for hand grasp and release, supination, elbow flexion, and extension and arm adduction. Due to peripheral denervation, transposition and subsequent stimulation of the paralyzed latissimus dorsi muscle provided elbow flexion and transfer and stimulation of the paralyzed extensor carpi ulnaris muscle provided forearm supination. A suspended sling provided shoulder joint stability. The subject controlled stimulation proportionally using contralateral shoulder motion sensed by a position transducer. Control of stimulated hand grasp and release were coupled with stimulated arm motions so that hand-to-mouth activities could be accomplished with one motion of the contralateral shoulder. With this system, the subject was able to grasp a milk carton placed in the hand and lift and lower it from his mouth to drink from a short straw. He could also scoop a semisolid substance with an adapted spoon and lift and lower it from the work surface to his mouth to eat. The subject required assistance to place the milk carton or spoon in his hand and position the plate for scooping. Further investigation is needed to generate the necessary arm movements to make completion of these tasks possible without assistance and to expand the range of activities possible with the FES system.

Abstract
BACKGROUND The incidence of paralytic scoliosis subsequent to acquired spinal cord injury (SCI) has been reported to range from 46% to 97% in patients injured before the adolescent growth spurt. OBJECTIVE The purpose of this report is to review early bracing of children with SCI as a means of preventing or delaying surgical fusion. METHODS Patient records from January 1996 to December 2001 from the Shriners Hospitals for Children-Philadelphia were retrospectively reviewed; 123 patients met the inclusion criteria of cervical or thoracic SCI prior to skeletal maturity. Patients were divided into 5 groups based on their radiographic curve severity at presentation, and then they were subdivided into a group that was managed with prophylactic bracing and a group that was not braced. End-points included completion of bracing regimen, surgery, or cessation of growth. RESULTS Forty-two patients presented with a curve < 10 degrees, 29 of whom were braced, and 13 who were not. Of the braced group, 13 (45%) went on to surgery, whereas 10 (77%) of the nonbraced group had surgical correction (P = 0.03). Of the patients who were initially braced, the average time to surgery was 8.5 years, whereas that for the nonbraced group was 4.2 years (P = 0.002). A similar trend was seen in the patients who presented with an initial curve between 11 degrees and 20 degrees (P < 0.001). There was no significant difference between time to surgery for the braced and nonbraced patient groups at higher (> 20 degrees) initial curve presentations. CONCLUSION Bracing of children with SCI before significant curve formation (< 20 degrees) delays the time to surgical correction of the deformity as it progresses. At smaller curves (< 10 degrees), bracing may even prevent the need for surgery. As curve size increases (> or = 20 degrees), bracing seems to play a limited role, because it does not seem to prevent surgery or delay time to surgical correction.

Abstract
BACKGROUND The prevalence of neuromuscular scoliosis in children with spinal cord injury (SCI) is high. Published reports suggest that age at time of injury is the most important determinant. No studies have evaluated neurological characteristics using standardized methods to determine if they are strong predictors of scoliosis. OBJECTIVE To test the hypothesis that neurological level, motor score, and injury severity are strong predictors of neuromuscular scoliosis. METHODS Two hundred seventeen children were evaluated using the testing guidelines of the International Standards for Neurological Classification of Spinal Cord Injury. Cobb angles were calculated from plain radiographs as a measure of scoliosis. Multivariate analysis with statistical selection was used to determine predictors of worst Cobb angle and spinal fusion. The odds of having a spine fusion for subjects with at least 2-year follow-up and injured prior to (n=16) and after (n=91) 12 years of age were calculated. RESULTS The hypothesis was not supported. Although there was a very high prevalence (100%) of scoliosis in the study sample, age at time of injury was the only predictor of worst curve (P < .0001) and spine fusion (P < .007). The calculated odds ratio demonstrated that children injured <12 years were 3.7 times more likely to have a spine fusion (95% CI, 0.31-44.64). CONCLUSION There is a very high prevalence of neuromuscular scoliosis in pediatric SCI. Neurological level, motor level, and severity of injury are not strong predictors. Age is the only predictor of worst curve and spine fusion.

Abstract
STUDY DESIGN Series of four single subjects with and without intervention design. OBJECTIVES To describe a minimally invasive surgical technique used to implant the Freehand System during initial spinal cord injury (SCI) rehabilitation and to report rehabilitation outcomes of four recently injured adolescents using the Freehand System. SETTING Nonprofit children's hospital specializing in orthopedic and SCI care. METHODS Four subjects with C5 tetraplegia between 13 and 16 years of age and between 9 and 16 weeks following traumatic SCI underwent implantation of the Freehand System using minimally invasive surgical techniques. Outcomes on muscle strength, pinch force, hand function, performance of activities of daily living and satisfaction with and without the Freehand System were collected. RESULTS Each subject was successfully implanted with the Freehand System without perioperative complications and employed the Freehand System during therapy services and ad lib on the rehabilitation floor. At the last follow-up, every subject remained a motor candidate for the Freehand System. With the Freehand System, average lateral and palmar pinch force was 1.8 and 1.6 kg respectively; average pinch force without functional electrical stimulation (FES) was 0.29 kg. With the Freehand System, three subjects improved their rate of performance on The Upper Extremity Capabilities Questionnaire. All subjects increased their level of independence on The Quadriplegia Index of Function. On the Canadian Occupational Performance Measure (COPM) with the Freehand System, average performance and satisfaction scores improved for every patient. Three of the four subjects continued to use the system at home. CONCLUSION This case series demonstrates that the Freehand System can vastly improve hand function and performance of rehabilitation activities within days after a minimally invasive implant procedure during initial SCI rehabilitation. Satisfaction with the Freehand System beyond initial rehabilitation is evidenced by continued use at home.

Abstract
STUDY DESIGN Cross-sectional non-experimental study. OBJECTIVES To examine diagnostic accuracy of diffusion tensor imaging (DTI) for pediatric spinal cord injury (SCI). SETTING Pediatric Orthopedic Hospital. METHODS Thirty-five subjects, 10 SCI and 25 controls, mean age 13.38 years underwent two scans with 3.0 T MR scanner. Fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD) values were calculated. Subjects with SCI underwent examination of muscle strength, sensation and sacral sparing. Mean and s.d. values for FA, AD and RD were compared by group (controls, SCI with sacral sparing, SCI without sacral sparing) using analysis of variance for repeated measures. Comparisons were also made of DTI values at the injury site to values from cervical regions outside of the injury site. Specificity, sensitivity, receiver operating characteristics area under the curve (ROC AUC) and corresponding 95% confidence intervals were calculated. Resampling methods were used to validate the estimates from the final models. RESULTS FA values differed among SCI subjects with intact sacral sparing, absent sacral sparing and controls, P<0.003 (adjusted). DTI values in combination showed the strongest diagnostic accuracy for predicting the presence of anal contraction (AD, RD; ROC AUC=0.90), deep anal pressure (FA; ROC AUC=0.88), S4-5 sensation (FA, RD; ROC AUC=0.93), motor level (FA, AD, RD; ROC AUC=0.92) and MRI level (FA, AD, RD; ROC AUC=0.92). Bootstrap and Jackknife median values indicated consistency of the parameter estimates. CONCLUSION The predictive accuracy of DTI for sacral sparing end points and motor and MRI level of injury was good to strong.

Abstract
STUDY DESIGN Post intervention, repeated measures design, comparing two interventions. SETTING Orthopedic pediatric hospital specializing in spinal cord injury. METHODS Nine subjects, ages 7-20 years, received an eight-channel implanted lower extremity functional electrical stimulation (FES) system for standing and walking. Electrodes were placed to stimulate hip and knee extension, and hip abduction and adduction. Standing and walking were achieved through constant stimulation to the implanted muscles, allowing a swing through gait pattern with an assistive device. After training with FES and long leg braces (LLB), subjects were tested in eight upright mobility activities, which were scored based upon completion time and level of independence. RESULTS Seven subjects completed data collection. These subjects completed four activities faster (P<0.02) and five activities more independently (P<0.025) with FES as compared to LLB. Transitions between sitting and standing, which were scored in isolation for two mobility activities, were achieved faster and with more independence with FES. In addition, subjects reported preferring FES for the majority of activities. No activity required more time or more assistance to complete with FES as compared to LLB. CONCLUSION The implanted FES system provided these subjects with enhanced functional abilities over traditional LLB and decreased the need for physical assistance by a caregiver, suggesting that it is a realistic alternative for upright mobility in a pediatric population with spinal cord injury.

Abstract
STUDY DESIGN Randomized clinical trial. OBJECTIVES To determine the effect of cycling and/or electrical stimulation on hip and knee bone mineral density (BMD) in children with spinal cord injury (SCI). SETTING Children's hospital specializing in pediatric SCI. METHODS A total of 30 children, aged 5-13 years, with chronic SCI were randomized to one of three interventions: functional electrical stimulation cycling (FESC), passive cycling (PC), and non-cycling, electrically stimulated exercise (ES). Each group exercised for 1 h, three times per week for 6 months at home. The hip, distal femur and proximal tibia BMD were examined via dual-energy X-ray absorptiometry (DXA) pre- and post-intervention. RESULTS In all, 28 children completed data collection. The FESC group exhibited increases in hip, distal femur and proximal tibia BMD of 32.4, 6.62 and 10.3%, respectively. The PC group exhibited increases at the hip (29.2%), but no change at the distal femur (1.5%) or proximal tibia (-1.0%). The ES group had no change at the hip (-0.24%) and distal femur (3.3%), but a loss at the proximal tibia (-7.06%). There were no differences between groups or within groups over time. Significant negative correlations were found between baseline BMD and the amount of BMD change. CONCLUSION Although not achieving statistical significance, hip BMD changes observed were greater than the reported 0.9-10% gains after exercise for children with and without disability. Thus, cycling with and without electrical stimulation may be beneficial for skeletal health in pediatric SCI, but further research is needed with a larger sample size.

Abstract
PURPOSE The Patient-Reported Outcomes Measurement Information System (PROMIS(®)) provides adult and pediatric self-report measures of health-related quality of life designed for use across medical conditions and the general population. The purpose of this study was to examine the feasibility and validity of the PROMIS(®) Pediatric Short Form and computer-adaptive test (CAT) mobility measures in children with cerebral palsy (CP). METHODS Eighty-two children with CP completed self-report (PROMIS(®) Mobility Short Form, PROMIS(®) Mobility CAT, Pediatric Quality of Life Inventory™) and performance-based assessments of mobility (Timed Up and Go, Gross Motor Function Measure). Parents provided three proxy reports of child mobility (Pediatric Outcomes Data Collection Instrument, Functional Assessment Questionnaire, Shriners Hospitals for Children CP-CAT). Validity of PROMIS(®) instruments was examined through correlations with other measures and "known groups" analyses determined by Gross Motor Function Classification System (GMFCS). RESULTS On average, the PROMIS(®) CAT required less than seven items and 2 minutes to administer. Both PROMIS(®) measures showed moderate to high correlations with child- and parent-proxy report of child mobility; correlations with performance-based measure were small for the PROMIS(®) Short Form and non-significant for the PROMIS(®) CAT. All measures except for the PROMIS(®) CAT were able to distinguish between GMFCS categories. CONCLUSIONS Results support the convergent and discriminant validity of the pediatric PROMIS(®) Mobility Short Form in children with CP. The PROMIS(®) Mobility CAT correlates well with child report and parent report of mobility but not with performance-based measures and does not differentiate between known mobility groups.

Abstract
BACKGROUND AND PURPOSE DTI in the brain has been well established, but its application in the spinal cord, especially in pediatrics, poses several challenges. The small cord size has inherent low SNR of the diffusion signal intensity, respiratory and cardiac movements induce artifacts, and EPI sequences used for obtaining diffusion indices cause eddy-current distortions. The purpose of this study was to 1) evaluate the accuracy of cervical spinal cord DTI in children using a newly developed iFOV sequence with spatially selective 2D-RF excitations, and 2) examine reproducibility of the DTI measures. MATERIALS AND METHODS Twenty-five typically developing subjects were imaged twice using a 3T scanner. Axial DTI images of the cervical spinal cord were acquired with this sequence. After motion correction, DTI indices were calculated using regions of interest manually drawn at every axial section location along the cervical spinal cord for both acquisitions. Various DTI indices were calculated: FA, AD, RD, MD, RA, and VR. Geometric diffusion measures were also calculated: Cp, Cl, and Cs. RESULTS The following average values for each index were obtained: FA = 0.50 ± 0.11; AD = 0.97 ± 0.20 × 10(-3)mm(2)/s; RD = 0.41 ± 0.13 × 10(-3)mm(2)/s; MD = 0.59 ± 0.15 × 10(-3)mm(2)/s; RA = 0.35 ± 0.08; VR = 0.03 ± 0.00; Cp = 0.13 ± 0.07; Cl = 0.29 ± 0.09; and Cs = 0.58 ± 0.11. The reproducibility tests showed moderate to strong ICC in all subjects for all DTI parameters (ICC>0.72). CONCLUSIONS This study showed that accurate and reproducible DTI parameters can be estimated in the pediatric cervical spinal cord using an iFOV EPI sequence.
