Abstract
BACKGROUND Orthotic devices are required for walking in many individuals with myelomeningocele. Evidence concerning orthosis use is sparse, partly because of heterogeneity among groups and different definitions of the neurological level. OBJECTIVES The objective of this study was to investigate ambulation regarding orthosis use and satisfaction with orthoses after intense orthotic management during childhood. STUDY DESIGN The study design is a retrospective follow-up with a cross-sectional study at adult age. METHODS Participants comprised 59 persons born in 1985 or later. Ambulation was categorized as community (Ca), household (Ha), nonfunctional (N-f), and nonambulation (N-a) groups. Orthosis use was registered at approximately 5 (Age5) and 12 (Age12) years of age and in adulthood (AdultAge). Satisfaction with orthoses was evaluated at AdultAge. RESULTS At Age5, Age12, and AdultAge, orthoses were used by 100%, 98%, and 78% of participants, respectively. Ambulation deteriorated between Age5 and Age12 in 17% of participants and between Age12 and AdultAge in 46%. At AdultAge, 63% maintained their ambulatory function; and muscle function and hip and knee flexion contractures were strongly correlated with ambulation. The ambulation groups did not differ regarding satisfaction with device or services, except in 2 single items where the Ha group differed in ratings from the N-f and N-a groups. CONCLUSION The high frequency of orthosis use and similar satisfaction in all ambulation groups emphasize that early planning and follow-up of orthosis treatment during growth are important for mobility in adulthood. Our results also underline the importance of a close assessment of each individual's condition.

Abstract
Quantitative data assessment on the basis of three-dimensional gait analysis has been routinely used in the evaluation of pathological gait of children with cerebral palsy. However, a similar quantitative methodology has not been applied for spina bifida patients in whom atypical gait patterns are thought to correlate with various levels of neurological paralysis. The purpose of this study is to investigate the differences among gait patterns in spina bifida between different levels of neurological lesions using quantitative methods: Gait profile score (GPS) and gait variable scores (GVS), scoring subject's gait deviation from a reference. In this cross-sectional study, 22 children with spina bifida (11 women, 11 men; mean age 9.4 years, SD 3.8 years, range 3-17 years), were examined using three-dimensional gait analysis from 2008 to 2018. Physical examination allowed for classification of each of the 44 limbs as either L4, L5 or S1 and comparison with the GPS and GVS using a linear mixed model. GPS and the GVS of the pelvis and hip range of motion in the coronal plane were significantly higher in the L4 group than in the L5 and S1 groups (GPS, P = 0.041, P = 0.003, respectively; GVS of pelvis, P = 0.001, P = 0.001; GVS of hip, P < 0.001, P < 0.001) GVS (foot progression angle) was significantly lower in the S1 group than in L4 and L5 groups (P < 0.001, P = 0.037). We found that GPS and GVS enable us to quantitatively assess the differences among gait patterns between different neurological levels. The scoring tool showed the potential for detecting individual neurological changes.

Abstract
PURPOSE Previous studies have found motor function to correlate with spinal motor level and, accordingly, individuals with spina bifida are frequently categorized clinically in this manner. The aim of the current study was to describe how lower extremity functions including strength, selective motor control, and mirror movements vary by motor level in children and young adults with spina bifida. METHODS A single center, retrospective, cross-sectional, descriptive study using data collected in the National Spina Bifida Patient Registry and by a gait laboratory was performed. RESULTS Seventy-seven individuals with spina bifida were included with the majority having myelomeningocele (59 lumbar, 18 sacral motor level). Lower extremity strength and selective motor control varied to a certain extent with motor level. However, 90% of individuals showed strength or weakness in at least one muscle group that was unexpected based on their motor level. Mirror movements did not clearly vary with motor level. CONCLUSION Lower extremity strength, selective motor control, and mirror movements in individuals with spina bifida were not entirely predicted by motor level. This highlights the possible need for an improved spina bifida classification system that describes not only spinal motor level but more clearly defines a particular individual's functional motor abilities.

Abstract
OBJECTIVE To provide descriptive data on ambulatory ability and muscle strength in a large cohort of individuals with spina bifida enrolled in a National Spina Bifida Patient Registry and to investigate factors associated with ambulatory status. DESIGN Cross-sectional analysis of data from a multisite patient registry. RESULTS Descriptive analysis of mobility variables for 2604 individuals with spina bifida aged 5 and older are presented from 19 sites in the United States. Analysis of a subset of National Spina Bifida Patient Registry data from 380 individuals from 3 sites accompanied by data from a specialized spina bifida electronic medical record revealed that those with no history of a shunt, lower motor level, and no history of hip or knee contracture release surgery were more likely to be ambulatory at the community level than at the household or wheelchair level. CONCLUSION This study is the first to examine factors associated with ambulatory status in a large sample of individuals with myelomeningocele and nonmyelomeningocele subtypes of spina bifida. Results of this study delineate the breadth of strength and functional abilities within the different age groups and subtypes of spina bifida. The results may inform physicians of the characteristics of those with varying ambulatory abilities.

Abstract
OBJECTIVES To describe walking measurement in children with spina bifida and to identify patterns in the use of walking measures in this population. DATA SOURCES Seven medical databases-Medline, PubMed, Embase, Scopus, Web of Science, CINAHL, and AMED-were searched from the earliest known record until March 11, 2014. Search terms encompassed 3 themes: (1) children; (2) spina bifida; and (3) walking. STUDY SELECTION Articles were included if participants were children with spina bifida aged 1 to 17 years and if walking was measured. Articles were excluded if the assessment was restricted to kinematic, kinetic, or electromyographic analysis of walking. A total of 1751 abstracts were screened by 2 authors independently, and 109 articles were included in this review. DATA EXTRACTION Data were extracted using standardized forms. Extracted data included study and participant characteristics and details about the walking measures used, including psychometric properties. Two authors evaluated the methodological quality of articles using a previously published framework that considers sampling method, study design, and psychometric properties of the measures used. DATA SYNTHESIS Nineteen walking measures were identified. Ordinal-level rating scales (eg, Hoffer Functional Ambulation Scale) were most commonly used (57% of articles), followed by ratio-level, spatiotemporal measures, such as walking speed (18% of articles). Walking was measured for various reasons relevant to multiple health care disciplines. A machine learning analysis was used to identify patterns in the use of walking measures. The learned classifier predicted whether a spatiotemporal measure was used with 77.1% accuracy. A trend to use spatiotemporal measures in older children and those with lumbar and sacral spinal lesions was identified. Most articles were prospective studies that used samples of convenience and unblinded assessors. Few articles evaluated or considered the psychometric properties of the walking measures used. CONCLUSIONS Despite a demonstrated need to measure walking in children with spina bifida, few valid, reliable, and responsive measures have been established for this population.

Abstract
We aimed to disentangle the proportional contributions of upper and lower motor neuron dysfunction to motor impairment in children with spina bifida. We enrolled 42 children (mean age, 11.2 years; standard deviation, 2.8 years) with spina bifida and 36 control children (mean age, 11.4 years; standard deviation, 2.6 years). Motor impairment was graded to severity scales in children with spina bifida. We recorded motor evoked potentials after transcranial and lumbosacral magnetic stimulation and compound muscle action potentials after electric nerve stimulation. Regarding lower motor neuron function, severely impaired children with spina bifida demonstrated smaller compound muscle action potential areas and lumbosacral motor evoked potential areas than control children; mildly impaired children hardly differed from control children. Compound muscle action potential latencies and lumbosacral motor evoked potential latencies did not differ between children with spina bifida and control children. Regarding upper motor neuron function, children with spina bifida demonstrated smaller transcranial motor evoked potential areas and longer central motor conduction times than control children. The smallest motor evoked potential areas and longest central motor conduction times were observed in severely impaired children. In children with spina bifida, the contribution of upper motor neuron dysfunction to motor impairment is more considerable than expected from clinical neurologic examination.

Abstract
PURPOSE To determine the effect of enhanced sensory input on the step frequency of infants with myelomeningocele (MMC) when supported on a motorized treadmill. METHODS Twenty-seven infants aged 2 to 10 months with MMC lesions at, or caudal to, L1 participated. We supported infants upright on the treadmill for 2 sets of 6 trials, each 30 seconds long. Enhanced sensory inputs within each set were presented in random order and included baseline, visual flow, unloading, weights, Velcro, and friction. RESULTS Overall friction and visual flow significantly increased step rate, particularly for the older subjects. Friction and Velcro increased stance-phase duration. Enhanced sensory input had minimal effect on leg activity when infants were not stepping. CONCLUSIONS : Increased friction via Dycem and enhancing visual flow via a checkerboard pattern on the treadmill belt appear to be more effective than the traditional smooth black belt surface for eliciting stepping patterns in infants with MMC.

Abstract
PURPOSE To describe motor development toward ambulation in children with myelomeningocele. METHODS Forty-three children were followed prospectively from 6 months to 6 years of age. RESULTS Walking function had been achieved at the 1-year follow-up in 2 of 38 children, at the 1.5-year follow-up in 7 of 39, at the 2-year follow-up in 14 of 36, at the 3-year follow-up in 21 of 28, at the 4-year follow-up in 28 of 36, and at the 6-year follow-up in 30 of 38. At the 6-year follow-up, spasticity was present in 22 of 38 children, 42 of 43 used orthoses, and 9 children had not achieved ambulation expected with respect to muscle function. CONCLUSIONS In children with myelomeningocele, walking starts in some during the first year of life and is seen increasingly more frequently until 6 years of age. Motor development before ambulation varies among children with similar muscle function. An increased incidence of spasticity is found among those not having achieved ambulation with respect to muscle function.

Abstract
The use of quantitative models for evaluating upper extremity (UE) dynamics in children with myelomeningocele (MM) is limited. A biomechanical model for assessment of UE dynamics during Lofstrand crutch-assisted gait in children with MM is presented. This pediatric model may be a valuable tool for clinicians to characterize crutch-assisted gait, which may advance treatment monitoring, crutch prescription, and rehabilitation planning for children with MM. Nine subjects with L3 or L4 level myelodysplasia (mean+/-S.D. age: 11.1+/-3.8 years) were analyzed during forearm crutch-assisted gait: (1) reciprocal gait and (2) swing-through gait. Three-dimensional (3D) dynamics of the UE were acquired and the Pediatric Outcomes Data Collection Instrument (PODCI) was administered. The goal of this study was to determine if meaningful differences occur between gait patterns in UE kinematics and kinetics, and if correlations exist between dynamics and functional outcomes. Temporal-distance parameters showed significant differences between reciprocal and swing-through gait in stride length, and stance duration. All joint ranges of motion were greater during swing-through gait. Thorax, elbow and crutch ranges of motion were found to be significantly different between gait patterns. Kinetic results demonstrated significant differences between reciprocal and swing-through gait, bilaterally, at all joints for the force variables of mean superior/inferior force, range of force, and maximum inferior force. Functional outcomes were strongly correlated with joint dynamics. Accurate quantitative assessment is essential for preventing injury in long-term crutch users. This study has potential for improving clinical intervention strategies and therapeutic planning of ambulation for children with MM.

Abstract
OBJECTIVES Describe and discuss the efficacy and safety of botulinum toxin type A (BTX-A) intradetrusor injections in children with neurogenic detrusor overactivity (NDO) and urinary incontinence or overactive bladder symptoms of neurogenic origin (NOAB). METHODS A MEDLINE and EMBASE search for clinical studies involving BTX-A injected into the detrusor of children with NDO or NOAB was performed, prior to data analysis. RESULTS A total of six articles evaluating the efficacy and safety of Botox in patients with NDO and incontinence/NOAB were selected. The underlying neurological disease was myelomeningocele in 93% of patients. Most were over 2 years of age. The most common amount of Botox injected was 10-12 U/kg with a maximal dose of 300 U, usually as 30 injections of 10 U/ml in the bladder (excluding the trigone) under cystoscopic guidance and general anaesthesia. Most of the studies reported a significant improvement in clinical (65-87% became completely dry) as well as urodynamic (in most studies mean maximum detrusor pressure was reduced to <40 cm H(2)O and compliance was increased >20 ml/cm H(2)O) variables, without major adverse events. CONCLUSIONS Botox injections into the detrusor provide a clinically significant improvement and seem to be very well tolerated in children with NDO and incontinence/NOAB refractory to antimuscarinics.

Abstract
The use of quantitative methods for evaluating upper extremity (UE) dynamics in children with myelomeningocele (MM) is currently limited. We present a novel biomechanical model for assessment of UE dynamics during Lofstrand (forearm) crutch-assisted gait with application in 9 children with MM. Two prominent types of forearm, crutch-assisted gait patterns were studied: 1) reciprocal gait (RG) and 2) swing-through gait (STG). The model demonstrated the ability to successfully detect meaningful differences in wrist, elbow, shoulder and crutch dynamics in the population of 9 children tested. Significant differences in kinetics with reciprocal and swing-through gait patterns were found bilaterally at all joints. Notable differences were found in the mean superior/inferior joint forces, ranges of joint force, and maximum inferior joint forces. Accurate quantitative assessment may help to prevent injury from longer-term crutch use and has the potential for improving clinical intervention and therapeutic management of ambulation in children with MM.

Abstract
PURPOSE Modern principles for treatment of patients with myelomeningocele include early closure of the neural tube defect, neurosurgical treatment of hydrocephalus and treatment aimed at minimizing contractures and joint dislocations. The aim is to achieve a better survival rate and a better quality of life (QOL). Better ambulatory function is thought to improve the management of activities of daily living. This study focused on evaluating which factors might affect ambulation, function and health-related QOL in children with myelomeningocele. METHODS Thirty-eight patients with neurological deficit from myelomeningocele were examined in an unbiased follow-up. This included a physical examination using validated methods for ambulatory function and neuromuscular status, chart reviews and evaluation of radiographs in terms of hip dislocation and spine deformity. The Pediatric Evaluation of Disability Inventory (PEDI) was used to measure mobility, self-care and social function, and the Child Health Questionnaire (CHQ-PF50) was used to measure QOL. RESULTS Muscle function class, quadriceps strength, spasticity in hip and/or knee joint muscles and hip flexion contracture as well as the ambulatory level all affected functional mobility as well as self-care/PEDI. Patients with hip dislocation, spinal deformity or those who were mentally retarded also had significantly worse functional mobility. Besides being affected by the severity of the neurological lesion, self-care/PEDI was significantly impaired by hip flexion contracture and absence of functional ambulation. General health-related QOL was significantly lower in this patient group than for US norms. Nonambulatory and mentally retarded patients had a significantly lower physical function of their QOL (CHQ). CONCLUSIONS The severity of the disease, i.e. reduced muscle strength and occurrence of spasticity around hip/knee, affected ambulation, functional mobility and self-care. Acquired deformities (hip dislocation and spine deformity) affected functional ambulation only. Patients with reduced functional mobility and self-care experienced lower physical QOL. Children with myelomeningocele had significantly reduced QOL compared to healthy individuals.

Abstract
Appropriate models for quantitative evaluation of upper extremity dynamics in children with myelomeningocele are limited. Therefore, a three-dimensional (3D) biomechanical model of the upper extremities was developed for quantification during Lofstrand crutch-assisted gait in children with myelomeningocele. The model accurately tracks the joint angles of the trunk, shoulders, elbows, wrists, and crutches. Lofstrand crutches are instrumented with six-axis load cells to obtain force and moment components. The model is applied while performing crutch-assisted ambulatory patterns (alternate gait and swing-through gait). Analysis indicates that the model is suitable for quantifying upper extremity motion during crutch-assisted gait. This model has been designed for dynamic assessment of ambulatory patterns (upper and lower extremities) that present with pediatric myelomeningocele. It is hoped that the study findings will prove useful through advances in treatment monitoring, crutch prescription and therapeutic planning.

Abstract
A consecutive series of 17 children (six males, 11 females; mean age 11y 11mo [SD 4y 5mo]; range 3y 11mo-17y 4mo) with plantarflexor weakness was assessed to compare gait differences between a carbon fibre spring orthosis (CFSO) and participants' regular orthoses. Twelve children had myelomeningocele, four children had arthrogryposis, and one child had neuropathy with peripheral muscle pareses. All participants underwent clinical examination and 3D gait analysis. Parents answered a questionnaire to assess subjective perceptions of the orthoses. Results from 3D gait analysis provided evidence that CFSOs enhance gait function in most participants by improving ankle plantarflexion moment (p<0.001), ankle positive work (p<0.001), and stride length (p<0.001). The CFSO did not suit all participants, which emphasizes the importance of analyzing each patient's needs.

Abstract
BACKGROUND/OBJECTIVE We present a 3-dimensional biomechanical model of the upper extremities to characterize joint dynamics during 2 patterns of Lofstrand crutch-assisted gait in children with myelomeningocele. The upper extremity model incorporates recommendations by the International Society of Biomechanics. METHODS A Vicon motion analysis system (14 cameras) captured the marker patterns. Instrumented crutches measured reaction forces. Five subjects with L3 or L4 level myelodysplasia (aged 9.8 +/- 1.6 years) were analyzed during reciprocal and swing-through Lofstrand crutch-assisted gait. RESULTS The mean walking speed, cadence, and stride length were greatest during swing-through gait. Although the gait patterns had different morphologies, the thorax and elbows remained in flexion, the wrists remained in extension, and the shoulders demonstrated both flexion and extension throughout the gait cycles. Swing-through gait showed larger ranges of motion for all joints than reciprocal gait. Peak crutch forces were highest during swing-through gait. The model was effective in detecting significant differences in upper extremity joint dynamics between reciprocal and swing-through crutch-assisted gait in children with myelomeningocele. CONCLUSIONS Results support continued testing. Future work should include clinical and functional assessment in a correlated study of dynamics and function. Knowledge from the study may be useful in treatment planning and intervention.
