RESUMO
Cervical spinal cord injury (SCI) results in significant sensorimotor impairments below the injury level, notably in the upper extremities (UEs), impacting daily activities and quality of life. Regaining UE function remains the top priority for individuals post-cervical SCI. Recent advances in understanding adaptive plasticity within the sensorimotor system have led to the development of novel non-invasive neurostimulation strategies, such as spinal cord transcutaneous stimulation (scTS), to facilitate UE motor recovery after SCI. This comprehensive review investigates the neuromotor control of UE, the typical recovery trajectories following SCI, and the therapeutic potential of scTS to enhance UE motor function in individuals with cervical SCI. Although limited in number with smaller sample sizes, the included research articles consistently suggest that scTS, when combined with task-specific training, improves voluntary control of arm and hand function and sensation. Further, the reported improvements translate to the recovery of various UE functional tasks and positively impact the quality of life in individuals with cervical SCI. Several methodological limitations, including stimulation site selection and parameters, training strategies, and sensitive outcome measures, require further advancements to allow successful translation of scTS from research to clinical settings. This review also summarizes the current literature and proposes future directions to support establishing approaches for scTS as a viable neuro-rehabilitative tool.
RESUMO
PURPOSE: Activity-based locomotor training improves intrinsic trunk control in children with spinal cord injury (SCI). To reinforce these improvements, there is a need to develop community integration activities to allow a patient to apply the retrained nervous system at home. One activity that has been explored is rocking in a rocking chair. This paper describes the design, fabrication, and evaluation of a rocking chair for children with SCI. MATERIALS AND METHODS: The Quality Function Deployment (QFD) design process was used. Fundamental needs and features for the rocking chair were defined in a focus group with experienced therapists, and needs were then rated for importance. A House of Quality (HOQ) matrix was developed to correlate needs with design features, and a prototype design was generated. Virtual motion studies and finite element analysis (FEA) were utilized to assess the design. The chair was fabricated and physical testing was performed, including tipping and static and dynamic load assessments. RESULTS AND CONCLUSIONS: The needs identified through the QFD process were categorized into (1) safety, (2) therapeutic, (3) practical and aesthetic, and (4) data to track chair use. Features selected to meet these needs include safety stops, padding, straps, a stable base, armrests, adjustable footrest, and sensors to capture rocking data. FEA showed a factor of safety (FOS) > 5. Physical testing confirmed physical integrity, load-bearing capacity, and stability of the prototype glider rocking chair. The prototype provides a safe tool for further investigation of rocking for promotion of trunk muscle activation in children with SCI.
Rocking in a rocking chair promotes carryover of gained trunk control capacity, from clinic to home in a population that is non-ambulatory.Rocking provides opportunity for self-practice in population with severely compromised capacity.Rocking is a movement that may be performed when other types of movement cannot be readily performed, e.g., resistance exercise, movement against gravity.Rocking creates opportunity for repetitive, voluntary, self-directed movement that is inherently pleasurable and reinforcing.
RESUMO
Background: Acute flaccid myelitis (AFM) occurs rarely in children and adolescents when damage to spinal motor neurons rapidly causes flaccid paralysis of limb, trunk, and neck muscles and potentially respiratory failure. When neck muscles are weakened or paralyzed, a child loses head control, severely compromising engagement with their environment. Compensation for lack of head control is achieved with external support devices attached to a wheelchair, but there is no indication in the AFM literature of therapeutic efforts to restore head control. In this case series, we explore the possibility of the recovery of head control when children with AFM received activity-based restorative therapies (ABRTs) guided by principles targeting motor control. Case description: Three children, two male and one female, aged 6, 9, and 7, with a history of AFM-onset at 5, 7, and 4 years respectively, enrolled in an activity-based restorative therapies outpatient program targeting activation of the neuromuscular system below the lesion. Each of them lacked head control, was either ventilator-dependent or had a tracheostomy, and was a power wheelchair user via hand/foot control. Methods: Activity-based restorative therapies were provided 5 days/week: 1.5â h of activity-based locomotor training and 1.5â h of activity-based neuromuscular electrical stimulation. Results: An approach to addressing head/neck control developed iteratively across disciplines, from complete compensation with passive external head support to emerging head control during diverse tasks, e.g., sitting, reaching, driving a power chair, sit-to-stand, standing, stepping on a treadmill, and walking. Key principles identified and employed were (a) passive facilitation, (b) external head support, (c) posterior head support, (d) graded manual facilitation, and (e) independent head control. Discussion: The recovery of head control in children with paralysis due to AFM may be accelerated when executing a step-wise progression to effectively target and challenge head control in parallel with activity-based restorative therapies. In treating three children with a chronic lack of head control, a therapeutic strategy was iteratively developed guided by scientific principles, e.g., segmental assessment of control, to promote recovery of head control. While this strategy is encouraging, gaps in sensitive and responsive measurement instruments and treatment technologies persist in guiding assistance, challenging, and promoting independent head control.
RESUMO
OBJECTIVE: In adults with cervical spinal cord injury (SCI), transcutaneous spinal stimulation (scTS) has improved upper extremity strength and control. This novel noninvasive neurotherapeutic approach combined with training may modulate the inherent developmental plasticity of children with SCI, providing even greater improvements than training or stimulation alone. Because children with SCI represent a vulnerable population, we first must establish the safety and feasibility of any potential novel therapeutic approach. The objectives of this pilot study were to determine the safety, feasibility, and proof of principle of cervical and thoracic scTS for short-term effect on upper extremity strength in children with SCI. MATERIALS AND METHODS: In this nonrandomized, within-subject repeated measure design, seven participants with chronic cervical SCI performed upper extremity motor tasks without and with cervical (C3-C4 and C6-C7) and thoracic (T10-T11) site scTS. Safety and feasibility of using cervical and thoracic sites scTS were determined by the frequency count of anticipated and unanticipated risks (eg, pain, numbness). Proof-of-principle concept was tested via change in force production during hand motor tasks. RESULTS: All seven participants tolerated cervical and thoracic scTS across the three days, with a wide range of stimulation intensities (cervical sites = 20-70 mA and thoracic site = 25-190 mA). Skin redness at the stimulation sites was observed in four of 21 assessments (19%) and dissipated in a few hours. No episode of autonomic dysreflexia was observed or reported. Hemodynamic parameters (systolic blood pressure and heart rate) remained within stable limits (p > 0.05) throughout the assessment time points at baseline, with scTS, and after the experiment. Hand-grip and wrist-extension strength increased (p < 0.05) with scTS. CONCLUSIONS: We indicated that short-term application of scTS via two cervical and one thoracic site is safe and feasible in children with SCI and resulted in immediate improvements in hand-grip and wrist-extension strength in the presence of scTS. CLINICAL TRIAL REGISTRATION: The Clinicaltrials.gov registration number for the study is NCT04032990.
RESUMO
Incomplete spinal cord injuries (ISCI) in pediatrics and adults can lead to asymmetric motor impairments exhibiting as asymmetries of posture and gait. Recently, rehabilitation guidelines for adults with neurologic injuries have focused on gaining a functional gait pattern as measured by speed and distance, even if asymmetry deficits persist. Activity-based restorative therapies (ABRT) take advantage of activity-dependent neuroplasticity to change an individual's neuromuscular capacity. This is a report of an ambulatory child with chronic ISCI presenting with significant postural and gait asymmetries who enrolled in an ABRT program. Across 79 ABRT sessions, the child gained symmetry during sitting, standing, and walking. Even though this child was a functional ambulator at enrollment, targeting symmetry of movements via improved neuromuscular capacity further enhanced her achievement of kinematically appropriate function for participation in daily activities.
RESUMO
Neuromodulation via spinal stimulation is a promising therapy that can augment the neuromuscular capacity for voluntary movements, standing, stepping, and posture in individuals with spinal cord injury (SCI). The spinal locomotor-related neuronal network known as a central pattern generator (CPG) can generate a stepping-like motor output in the absence of movement-related afferent signals from the limbs. Using epidural stimulation (EP) in conjunction with activity-based locomotor training (ABLT), the neural circuits can be neuromodulated to facilitate the recovery of locomotor functions in persons with SCI. Recently, transcutaneous spinal stimulation (scTS) has been developed as a noninvasive alternative to EP. Early studies of scTS at thoracolumbar, coccygeal, and cervical regions have demonstrated its effectiveness in producing voluntary leg movements, posture control, and independent standing and improving upper extremity function in adults with chronic SCI. In pediatric studies, the technology of spinal neuromodulation is not yet widespread. There are a limited number of publications reporting on the use of scTS in children and adolescents with either cerebral palsy, spina bifida, or SCI.

The immature central nervous system is recognized as having substantial neuroplastic capacity. In this study, we explored the hypothesis that rehabilitation can exploit that potential and elicit reciprocal walking in nonambulatory children with chronic, severe (i.e., lower extremity motor score < 10/50) spinal cord injuries (SCIs). Seven male subjects (3-12 years of age) who were at least 1-year post-SCI and incapable of discrete leg movements believed to be required for walking, enrolled in activity-based locomotor training (ABLT; clinicaltrials.gov NCT00488280). Six children completed the study. Following a minimum of 49 sessions of ABLT, three of the six children achieved walking with reverse rolling walkers. Stepping development, however, was not accompanied by improvement in discrete leg movements as underscored by the persistence of synergistic movements and little change in lower extremity motor scores. Interestingly, acoustic startle responses exhibited by the three responding children suggested preserved reticulospinal inputs to circuitry below the level of injury capable of mediating leg movements. On the other hand, no indication of corticospinal integrity was obtained with transcranial magnetic stimulation evoked responses in the same individuals. These findings suggest some children who are not predicted to improve motor and locomotor function may have a reserve of adaptive plasticity that can emerge in response to rehabilitative strategies such as ABLT. Further studies are warranted to determine whether a critical need exists to re-examine rehabilitation approaches for pediatric SCI with poor prognosis for any ambulatory recovery.

CONTEXT/OBJECTIVE: Spinal cord injury (SCI) often results in a significant loss of mobility and independence coinciding with reports of decreased quality of life (QOL), community participation, and medical complications often requiring re-hospitalization. Locomotor training (LT), the repetition of stepping-like patterning has shown beneficial effects for improving walking ability after motor incomplete SCI, but the potential impact of LT on psychosocial outcomes has not been well-established. The purpose of this study was to evaluate one year QOL, community participation and re-hospitalization outcomes between individuals who participated in a standardized LT program and those who received usual care (UC). DESIGN/SETTING/PARTICIPANTS: A retrospective (nested case/control) analysis was completed using SCI Model Systems (SCIMS) data comparing one year post-injury outcomes between individuals with traumatic motor incomplete SCI who participated in standardized LT to those who received UC. OUTCOME MEASURES: Outcomes compared include the following: Satisfaction with Life Scale (SWLS™), Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF™), and whether or not an individual was re-hospitalized during the first year of injury. RESULTS: Statistically significant improvements for the LT group were found in the following outcomes: SWLS (P = 0.019); and CHART subscales [mobility (P = <0.001)]; occupation (P = 0.028); with small to medium effects sizes. CONCLUSION: Individuals who completed a standardized LT intervention reported greater improvements in satisfaction with life, community participation, and fewer re-hospitalizations at one year post-injury in comparison to those who received UC. Future randomized controlled trials are needed to verify these findings.

Objectives: To conduct a systematic review to examine the scientific literature for rehabilitation/habilitation among individuals with pediatric-onset spinal cord injury (SCI). Methods: A literature search of multiple databases (i.e., PubMed/MEDLINE, CINAHL, EMBASE, PsychINFO) was conducted and was filtered to include studies involving humans, published as full-length articles up to December 2020, and in English. Included studies met the following inclusion criteria: (1) ≥50% of the study sample had experienced a traumatic, acquired, nonprogressive spinal cord injury (SCI) or a nontraumatic, acquired, noncongenital SCI; (2) SCI onset occurred at ≤21 years of age; and (3) sample was assessed for a rehabilitation/habilitation-related topic. Studies were assigned a level of evidence using an adapted Sackett scale modified down to five levels. Data extracted from each study included author(s), year of publication, country of origin, study design, subject characteristics, rehabilitation/habilitation topic area, intervention (if applicable), and outcome measures. Results: One hundred seventy-six studies were included for review (1974-2020) with the majority originating from the United States (81.3%). Most studies were noninterventional observational studies (n = 100; 56.8%) or noninterventional case report studies (n = 5; 2.8%). Sample sizes ranged from 1 to 3172 with a median of 26 (interquartile range [IQR], 116.5). Rehabilitation/habilitation topics were categorized by the International Classification of Functioning, Disability and Health (ICF); most studies evaluated ICF Body Function. There were 69 unique clinical health outcome measures reported. Conclusion: The evidence for rehabilitation/habilitation of pediatric-onset SCI is extremely limited; nearly all studies (98%) are level 4-5 evidence. Future studies across several domains should be conducted with novel approaches to research design to alleviate issues related to sample sizes and heterogeneity.

Background: Spinal cord injury (SCI) in infancy halts typical development secondary to paralysis/paresis and the limited ability to engage with the environment. Traditional therapies further restrict a child via bracing, equipment, and medications. In contrast, activity-based restorative therapies (ABRT) promote activation of the neuromuscular system below the level of injury and affords a more typical sensorimotor experience. Case Description: A premature male infant exhibiting hypotonia, poor head control, and extremity weakness was diagnosed at age 5 months with a remote incomplete upper cervical SCI based on magnetic resonance imaging (MRI), presumed to have occurred perinatally. From 4 to 15 months of age, he received physical, occupational and speech therapies. Enrolled in an ABRT program at 15 months, he was unable to sit, pull-to-stand, stand, or walk and had upper extremity impairments. Results of the Bayley-III Scales of Infant and Toddler Development revealed gross and fine motor scores consistent with a 4-month-old. Methods: Activity-based restorative therapies was provided 5 day/week: 1.5 h of activity-based locomotor training and 1 h of activity-based occupational therapy. Results: Activity-based restorative therapies are reported for 177 sessions and are on-going. Improvements are noted in trunk control, standing, walking, grasp, in-hand manipulation, and associated kinematics. Bayley-III fine motor score improved to that of a 16-month-old and gross motor score to that of a 7-month-old. Discussion: While the two treatment periods (i.e., 4-15 months old and 15-24 months) were each â¼9 months, the child's accelerated progress toward typical development during the latter, ABRT period is noteworthy. In comparison to the period of traditional therapies in which paralysis was compounded by a restrictive environment and compensation, ABRT provided a potentially rich sensorimotor experience with an emphasis on active weight-bearing and proper kinematics to activate the neuromuscular system below the lesion in an age-appropriate, task-specific context of activities. Improved physical capacity enabled exploration more typically associated with development at this age expanding the positive impact to other developmental domains.
RESUMO
As infancy is characterized by rapid physical growth and critical periods of development, disruptions due to illness or disease reveal vulnerability associated with this period. Spinal cord injury (SCI) has devastating consequences at any age, but its onset neonatally, at birth, or within the first year of life multiplies its impact. The immediate physical and physiological consequences are obvious and immense, but the effects on the typical trajectory of development are profound. Activity-based restorative therapies (ABRT) capitalize on activity-dependent plasticity of the neuromuscular system below the lesion and when provided to children with SCI aim to improve the child's neuromuscular capacity, health and quality of life. This is a report of an infant with a cervical SCI at birth resulting in paralysis of leg and trunk muscles and paresis of arm and hands who was enrolled in an ABRT program at 3 years of age. After 59 sessions of ABRT, the child demonstrated significant improvements in trunk control and arm function, as well as social and emotional development. Despite the chronicity of injury and low expectations for improvement with therapeutic interventions, ABRT had a positive impact on the child's physical capacity and provided benefits across multiple developmental domains.
RESUMO
OBJECTIVES: To establish the utility and feasibility of the International Spinal Cord Injury/Dysfunction (SCI/D) Bowel Function Basic Data Set Version 2.0 in pediatric SCI populations. METHODS: This was a noninterventional, repeated measure design conducted in Pennsylvania, Maryland, Illinois, Kentucky, and South Carolina. The International Spinal Cord Injury/Dysfunction (SCI/D) Bowel Function Basic Data Set Version 2.0 was administered repeatedly, twice at the point of care and once over the phone. Time to complete the data set was recorded. Inter- and intrarater reliability was examined by intraclass correlation coefficients (ICC) with 95% confidence intervals (CI), and agreement between the bowel function basic data set variables and medical records was calculated using percentages. Intrarater reliability involved the same person administering the data once at the point of care and once over the phone. RESULTS: Forty-one children/youth ages 1 to 20 years participated in this study. Average time to complete the data set was 5.17 minutes. Interrater reliability was good to excellent (ICC ≥ 0.75) for most variables. Five variables had moderate interrater reliability (ICC = 0.05-0.74) and three had poor interrater reliability (ICC < 0.05). With the exception of one variable that had poor intrarater reliability (constipating agent, ICC = 0.00) and one that approached moderate reliability (digital evacuation, ICC = 0.74), intrarater reliability was good to strong for every bowel variable (ICC = 0.88-1.00). Only 12 (32%) medical records had explicit documentation of one or more of the variables on the Basic Bowel Function Basic Data Set V2.0. CONCLUSION: The results support future research with a larger and more diverse sample of children with SCI to build upon the psychometric work described herein.

BACKGROUND: A recent study in pediatric spinal cord injury (SCI) demonstrated activity-based locomotor training (ABLT) improved trunk control, measured by the Segmental Assessment of Trunk Control (SATCo). It is not known whether improved trunk control is maintained and, if so, for how long. OBJECTIVES: The purpose was to determine the durability of improvements in trunk control after ABLT is stopped. We hypothesized that SATCo scores at follow-up would not significantly regress (a) beyond the score measured at discharge and (b) to the initial SATCo pre-ABLT level. METHODS: Patients were assessed pre ABLT, after completing an episode of care, and upon returning to the clinic 1 or more months without ABLT. Durability is a score change less than 3, which is the measurement error of the SATCo. RESULTS: Twenty-eight children (10 females; 4 ± 2.5 years old) completed at least 40 sessions of ABLT and returned for the follow-up 8 ± 7 months (range, 1-38) after the episode of care. Trunk control improved 6 ± 3/20 points with ABLT (p < .0001). At the follow-up, average SATCo score decreased 2 ± 2/20 points, and the follow-up SATCo score was 4 ± 3 points higher than pre ABLT (p < .0001). There was no correlation between the change in SATCo scores and changes in age, weight, height or elapsed time between discharge and follow-up. CONCLUSION: Improvements in trunk control due to ABLT were maintained, indicating ABLT is neurotherapeutic. Although not achieving complete recovery of trunk control, the immediate effects and sustained improvements provide support for a clinical shift to neurotherapeutic approaches and for continued research to achieve enhanced recovery.

In children with spinal cord injury (SCI), scoliosis due to trunk muscle paralysis frequently requires surgical treatment. Transcutaneous spinal stimulation enables trunk stability in adults with SCI and may pose a non-invasive preventative therapeutic alternative. This non-randomized, non-blinded pilot clinical trial (NCT03975634) determined the safety and efficacy of transcutaneous spinal stimulation to enable upright sitting posture in 8 children with trunk control impairment due to acquired SCI using within-subject repeated measures study design. Primary safety and efficacy outcomes (pain, hemodynamics stability, skin irritation, trunk kinematics) and secondary outcomes (center of pressure displacement, compliance rate) were assessed within the pre-specified endpoints. One participant did not complete the study due to pain with stimulation on the first day. One episode of autonomic dysreflexia during stimulation was recorded. Following hemodynamic normalization, the participant completed the study. Overall, spinal stimulation was well-tolerated and enabled upright sitting posture in 7 out of the 8 participants.

INTRODUCTION: Activity-based therapies (ABTs) focus on activating the neuromuscular system below the level of spinal cord injury (SCI) promoting neuromuscular capacity. CASE DESCRIPTION: A 2 year 7 month old with history of prematurity at 29 weeks, neonatal epidural abscess, resultant cervical SCI, respiratory failure, and global developmental delays presented for enrollment in an outpatient activity-based therapy program. Upon presentation to this program, he required nighttime mechanical ventilation via tracheostomy and daytime suctioning. He could not perform any age-appropriate activities and was described by his mother as 'present', neither engaged nor attentive. During and after 7 months of participation in ABTs including locomotor training and neuromuscular electrical stimulation, the patient demonstrated unexpected changes in his respiratory status leading to ventilator weaning with concomitant improvements in head and trunk control, participation, development, and quality of life. DISCUSSION: ABT was not only safe for a medically complex child, but also this intervention had a remarkable effect on unresolved respiratory capacity and a more widespread impact on other functions as well as development. A child with a chronic, severe SCI demonstrated positive and impactful improvements in health, functional status, and quality of life during an episode of ABT.
RESUMO
We investigated the impact of spinal cord injury (SCI) on cough capacity in 10 children (Mean ± SD, age 8 ± 4 years) and compared it to 15 typically developing children (age 8 ± 3 years). Participants underwent spirometry, single and sequential cough assessment with surface-electromyography from respiratory muscles. Inspiratory phase duration, inspiratory phase peak flow, inspiratory phase rise time, compression phase duration, expiratory phase rise time, expiratory phase peak airflow (EPPF) and cough volume acceleration (CVA) parameters of single and sequential cough were measured. Root mean square (RMS) values of right pectoralis-major, intercostal, rectus-abdominus (RA), and oblique (OB) muscles were calculated and mean of three trials were compared. The significance criterion was set at P < 0.05. The SCI group produced significantly lower lung volumes, EPPF, CVA, and RMS values of RA and OB during expiratory phases of single and sequential coughs. The decrease in activation in expiratory muscles in the SCI group accounts for the impaired expiratory flow and may contribute to risk of respiratory complications.

To investigate and compare trunk control and muscle activation during uncompensated sitting in children with and without spinal cord injury (SCI). Static sitting trunk control in ten typically developing (TD) children (5 females, 5 males, mean (SD) age of 6 (2)y) and 26 children with SCI (9 females, 17 males, 5(2)y) was assessed and compared using the Segmental Assessment of Trunk Control (SATCo) test while recording surface electromyography (EMG) from trunk muscles. The SCI group scored significantly lower on the SATCo compared to the TD group. The SCI group produced significantly higher thoracic-paraspinal activation at the lower-ribs, and, below-ribs support levels, and rectus-abdominus activation at below-ribs, pelvis, and no-support levels than the TD group. The SCI group produced significantly higher lumbar-paraspinal activation at inferior-scapula and no-support levels. Children with SCI demonstrated impaired trunk control with the ability to activate trunk muscles above and below the injury level.
RESUMO
INTRODUCTION: Spinal cord injury (SCI) in infancy magnifies the complexity of a devastating diagnosis. Children injured so young have high incidences of scoliosis, hip dysplasia, and respiratory complications leading to poor health and outcomes. We report the medical history, progression of rehabilitation, usual care and activity-based therapy, and outcomes for a child injured in infancy. Activity-based therapy (ABT) aims to activate the neuromuscular system above and below the lesion through daily, task-specific training to improve the neuromuscular capacity, and outcomes for children with acquired SCI. CASE PRESENTATION: A 3-month-old infant suffered a cervical SCI from a surgical complication with resultant tetraplegia. Until age 3, her medical complications included scoliosis, kyphosis, and pneumonia. Even with extensive physical and occupational therapy, she was fully dependent on caregivers for mobility and unable to roll, come to sit, sit, stand or walk. She initiated ABT at ~3 years old, participating for 8 months. The child's overall neuromuscular capacity improved significantly, especially for head and trunk control, contributing to major advances in respiratory health, novel engagement with her environment, and improved physical abilities. DISCUSSION: From injury during infancy until 3 years old, this child's health, abilities, and complications were consistent with the predicted path of early-onset SCI. Due to her age at injury, severity and chronicity of injury, she demonstrated unexpected, meaningful changes in her neuromuscular capacity during and post-ABT associated with improved health, function and quality of life for herself and her caregivers.

Background: In synergy with the mounting scientific evidence for the capacity of recovery after spinal cord injury (SCI) and training, new evidence-based therapies advancing neuromuscular recovery are emerging. There is a parallel need for outcome instruments that specifically address recovery. The Pediatric Neuromuscular Recovery Scale (Pediatric NRS) is one example with established content validity to assess neuromuscular capacity within task performance. Objective: The objective of this study was to determine interrater reliability of the Pediatric NRS to classify motor capacity in children after SCI. Methods: Pediatric physicians (3), occupational therapists (5), and physical therapists (6) received standardized training in scoring the scale, then rated video assessments of 32 children post SCI, 2-12 years of age, 78% non-ambulatory. Interrater reliability was analyzed using Kendall coefficient of concordance for individual Pediatric NRS items and overall score. Results: The interrater reliability coefficient was determined to be near 1 for the overall Pediatric NRS score (ICC = 0.966; 95% CI, 0.89-0.98). Twelve of 16 individual items exhibited high concordance coefficients (Kendall's W ≥ 0.8) and four items demonstrated concordance coefficients, < 0.8 and > 0.69. Interrater reliability was equivalent among groups defined by age and neurological level, but lower among non-ambulatory individuals. Conclusion: Strong interrater reliability was demonstrated by pediatric clinicians who scored children with SCI using the Pediatric NRS.

Background: Activity-based therapies aim to improve neuromuscular capacity after spinal cord injury (SCI). Objective: The purpose of this prospective study was to report the impact of Activity-based Locomotor Training (AB-LT) on neuromuscular capacity in pediatric patients with SCI. Methods: Participants were enrolled for their first episode of AB-LT for a minimum of 60 daily, 1.5-hour sessions. The Segmental Assessment of Trunk Control (SATCo) and the Pediatric Neuromuscular Recovery Scale (Pediatric NRS) were assessed initially, every 20 sessions, and post 60 sessions. Results: Twenty-six consecutive patients, mean age 5 years (SD = 3), completed a mean 55 sessions (SD = 4) within 63 weekdays (SD = 9). The Pediatric NRS total score improved significantly, adjusted mean 11.4, from initial to post-60 sessions (p < .05) with an average adjusted evaluation-to-evaluation 3.7 change. SATCo scores improved significantly across 60 sessions, mean change 5.2, an estimated 1.7 change between evaluations (p < .05). Age at enrollment and chronicity had no effect; however, initial neuromuscular capacity scores were negatively correlated with change scores (p < .05). Conclusion: Sixty AB-LT sessions significantly improved trunk and neuromuscular capacity in children with SCI, regardless of age or chronicity at enrollment. Patients with lower initial scores made greater improvements than patients with higher initial neuromuscular capacity. Anecdotal parent reports of their child's functional change in the home and community highlight the synergy between quantitative change in neuromuscular capacity and meaningful, improved quality of life and the need for formal investigation of this relationship.
