RESUMEN
BACKGROUND: Behavior change techniques (BCTs) have been extensively used in physical activity interventions for children, however, no systematic reviews have synthesized their effects. PURPOSE: The present review aimed to identify the most promising BCTs used in physical activity interventions associated with (i) increased physical activity behavior and (ii) positive psychosocial outcomes in children with chronic conditions. METHODS: A systematic search of 6 databases identified 61 articles as eligible for inclusion. Data, including BCTs, were extracted from these studies and analyzed descriptively. Due to the heterogeneity of interventions, chronic conditions, and outcome measures, a meta-analysis was not conducted. RESULTS: Social support (unspecified), graded tasks, generalization of target behavior, and credible source were the most commonly reported and most promising (i.e., present in 2+ studies evidencing significant effects) BCTs across all studies. These BCTs were found to be especially relevant to improving psychosocial outcomes in the short- and long-term and improving physical activity behaviors in the long-term. Meanwhile, to improve short-term physical activity behaviors, in addition to social support (unspecified), action planning, goal setting (behavior), and problem solving were found to be promising BCTs. CONCLUSIONS: The BCTs identified in this review may be relevant to incorporate when planning future interventions to support physical activity and psychosocial outcomes for children with chronic conditions.
Children with chronic conditions experience several barriers to engaging in physical activity. In order to overcome these unique barriers, physical activity interventions would need to incorporate specific strategies (called behavior change techniques [BCTs]) to encourage physical activity participation. The present review sought to identify BCTs that were successfully applied to physical activity interventions to increase physical activity behavior and improve psychosocial outcomes for children with chronic conditions. Across the 61 studies included within this review, the most commonly applied BCTs were providing instruction, allowing opportunities to practice the behavior, and demonstration of the behavior. Social support was also found to be the a successful BCT to increase physical activity behavior and improve psychosocial outcomes in the short- and long-term. Future physical activity interventions aimed at supporting physical activity behavior and psychosocial outcomes of children with chronic conditions could benefit from incorporating these strategies within intervention planning and delivery.

AIM: To determine if robotic assisted gait training (RAGT) using surface muscle electrical stimulation and locomotor training enhances mobility outcomes when compared to locomotor training alone in children with cerebral palsy (CP). METHOD: Forty children (18 females, 22 males; mean age 8y 1mo, SD 2y 1mo; range 5y 1mo-12y 11mo) with CP in Gross Motor Function Classification System levels (GMFCS) III, IV, and V were randomly assigned to the RAGT and locomotor training (RAGT+LT) group or locomotor training only group (dosage for both: three 1-hour sessions a week for 6 weeks). Outcomes were assessed at baseline T1 (week 0), post-treatment T2 (week 6), and retention T3 (week 26). The primary outcome measure was the Goal Attainment Scale. Secondary outcome measures included the 10-metre walk test, children's functional independence measure mobility and self-care domain, the Canadian Occupational Performance Measure, and the Gross Motor Function Measure. RESULTS: There were no significant differences between the groups for both the primary and secondary outcome measures. All participants completed the intervention in their original group allocation. There were no reported adverse events. INTERPRETATION: The addition of RAGT to locomotor training does not significantly improve motor outcomes in children with CP in GMFCS levels III, IV, and V. Future studies could investigate health and well-being outcomes after locomotor training. WHAT THIS PAPER ADDS: Marginally ambulant and non-ambulant children with cerebral palsy can participate in locomotor training. Robotic assisted gait training when added to locomotor training does not appear to be any more effective than locomotor training alone.

AIM: To investigate the use of ultrasound and magnetic resonance imaging (MRI) methodologies to assess muscle morphology and architecture in children with cerebral palsy (CP). METHOD: A scoping review was conducted with systematic searches of Medline, Embase, Scopus, Web of Science, PubMed, and PsycInfo for all original articles published up to January 2019 utilizing ultrasound and/or MRI to determine morphological and architectural properties of lower limb skeletal muscle in children with CP. RESULTS: Eighty papers used ultrasound (n=44), three-dimensional ultrasound (n=16), or MRI (n=20) to measure at least one muscle parameter in children and adolescents with CP. Most research investigated single muscles, predominantly the medial gastrocnemius muscle, included children classified in Gross Motor Function Classification System levels I (n=62) and II (n=65), and assessed fascicle length (n=35) and/or muscle volume (n=35). Only 21 papers reported reliability of imaging techniques. Forty-six papers assessed measures of Impairment (n=39), Activity (n=24), and Participation (n=3). INTERPRETATION: Current research study design, variation in methodology, and preferences towards investigation of isolated muscles may oversimplify the complexities of CP muscle but provide a foundation for the understanding of the changes in muscle parameters in children with CP. WHAT THIS PAPER ADDS: Current evidence is biased towards the medial gastrocnemius muscle and more functionally able children with cerebral palsy (CP). Variations in imaging techniques and joint positioning limit comparisons between studies. Clinimetric testing of parameters of CP muscle is not always considered. Assessment of parameter(s) of muscle with measures of participation is sparse.

INTRODUCTION: To characterise somatosensory discrimination impairment of the upper-limb across domains of tactile discrimination, limb position sense and haptic object recognition using the sense_assess© kids and examine associations with upper-limb motor performance in children with hemiplegic cerebral palsy (CP). METHODS: The sense_assess© kids was administered at one timepoint to 28 children, aged 6-15.5 years (M = 10.1, SD = 2.4), with hemiplegic CP (right hemiplegia n = 15) and Manual Ability Classification System Levels I (n = 11) and II (n = 17). Unimanual motor performance was quantified using the Box and Block Test. RESULTS: Tactile discrimination was impaired in 18, limb position sense in 20, and haptic object recognition was impaired in 21 of 28 children. Over 80% (23/28) of children had impaired somatosensory discrimination in one or more domains. Low to moderate correlations were observed between each measure of somatosensory discrimination and motor performance. Manual ability classification was associated with limb position sense and haptic object recognition. A moderate inverse correlation (r = -.57, p < .01) exists between the number of somatosensory domains impaired and motor performance. CONCLUSION: The frequency of somatosensory impairment in the upper limb of children in our sample was high and associated with manual ability, suggesting a need for routine assessment of somatosensation in this population.

BACKGROUND: The aim of this study is to contribute to the knowledge base on the long-term outcomes of evidence-based medical interventions used to improve gross motor function in children and adolescents with Cerebral Palsy. METHOD: Prospective cohort study of children with Cerebral Palsy in the birth years 2000-2009 attending a tertiary level service for children with Cerebral Palsy who's first recorded Gross Motor Function Classification System level was II. RESULTS: A total of 40 children were eligible for the study, of whom 28 (72.7%) enrolled. The Botulinum toxin A treatment for this cohort, (median and interquartile ranges) were: total number of lower limb Botulinum toxin A injections 11 (6.7, 5.5); total dose of Botulinum Toxin A per lower limb treatment 6.95 u/kg (4.5, 11); and dose of Botulinum Toxin u/kg/muscle 2.95 (2.2, 4). For all 28 subjects there was a median of 15 (8.5 to 22) Gross Motor Function Classification System level recordings: six of the 28 children (21.4%) improved from level II to level I, the remaining 22 children remained stable at level II (78.6%). In this highly treated population, the average 66 item Gross Motor Function Measure score for the 22 children in level II was 72.55, which is consistent with the mean of 68.5 reported in the original Ontario cohort. CONCLUSION: This cohort study has confirmed that children with Cerebral Palsy, Gross Motor Function level II treated at a young age with repeated doses of Botulinum Toxin A within an integrated comprehensive service, maintain or improve their functional motor level at a later age.

INTRODUCTION: Currently, our knowledge of standard data for muscle morphology in children is largely limited to the 1969 article by Brooke and Engel (BE). In 2016, we reported normal muscle morphology from vastus lateralis biopsies in ambulant children with cerebral palsy (CP). This report compares our normal biopsy results against BE standard value criteria. METHODS: Single-blind prospective cross-sectional study design. RESULTS: Results of biopsies taken in ambulant children with CP were normal according to morphometry and light and electron microscopy; however, only 5 of 10 fulfilled the BE standard value criteria. DISCUSSION: This short report highlights the requirement for contemporary age-specific normative data from a larger number of biopsies, including typically developing children. Review of the literature suggests that biopsy material may be available from typically developing children who were control patients in research trials. This morphometric data could contribute to expanding the normative data set. Muscle Nerve 59:590-590, 2019.

INTRODUCTION: In this study we aimed to determine the lower limb morphological characteristics of skeletal muscle of ambulant children with spastic cerebral palsy (CP) and typically developing (TD) children. METHODS: Seventeen children with spastic diplegic CP (10 boys and 7 girls, 5-12 years of age, Gross Motor Function Classification System [GMFCS] level I or II) and 19 TD children (8 boys and 11 girls, 5-11 years of age) underwent lower limb T1-weighted MRI. Morphological characteristics of the triceps surae, including muscle volume, anatomical cross-sectional area, muscle length, and subcutaneous adipose tissue, were digitally quantified, and the proportional distribution calculated. RESULTS: Children with GMFCS II had significantly reduced muscle volume, cross-sectional area, and muscle length, and increased subcutaneous fat compared with TD children. Children classified as GMFCS II consistently exhibited the greatest deficits in all morphology variables. DISCUSSION: Morphological variables were significantly different between the groups. These alterations have the potential to influence the functional capabilities of the triceps surae muscle group. Muscle Nerve 58:818-823, 2018.

AIM: This study aimed to track alterations in muscle volume for 6 months in children with cerebral palsy (CP) after the first exposure to botulinum neurotoxin A (BoNT-A), a commonly used focal spasticity treatment. METHOD: Eleven ambulant children (eight males, three females) with spastic CP, mean age 8 years 10 months (SD 3y 1mo) participated. Participants received injections to the affected gastrocnemius. The muscle volume of the gastrocnemius, soleus, tibialis anterior, and hamstrings was measured using magnetic resonance imaging. Muscle volume was normalized to bone length, and changes analysed relative to baseline. Assessments were conducted 1 week before, and 4 weeks, 13 weeks, and 25 weeks after BoNT-A treatment. RESULTS: All children demonstrated positive clinical and functional gains. Muscle volume of the injected gastrocnemius was found to be significantly reduced at 4 weeks (-5.9%), 13 weeks (-9.4%), and 25 weeks (-6.8%). Significant increases in normalized soleus muscle volume were identified at each follow-up, while hamstrings showed significant increase at 4 weeks only. INTERPRETATION: Absolute and normalized muscle volume of the injected muscle reduces after first BoNT-A exposure, and does not return to baseline volume by 25 weeks. Hypertrophy is seen in the soleus up to 25 weeks; the volume of the plantar flexor compartment is stable. WHAT THIS PAPER ADDS: Muscle atrophy after first botulinum neurotoxin A (BoNT-A) exposure in children with cerebral palsy is noted. Mild BoNT-A-induced muscle atrophy is still apparent 6 months after BoNT-A exposure. Hypertrophy is evident in soleus after gastrocnemius BoNT-A exposure. Total plantarflexor volume is unchanged.

BACKGROUND: Of children with hemiplegic cerebral palsy, 75% have impaired somatosensory function, which contributes to learned non-use of the affected upper limb. Currently, motor learning approaches are used to improve upper-limb motor skills in these children, but few studies have examined the effect of any intervention to ameliorate somatosensory impairments. Recently, Sense© training was piloted with a paediatric sample, seven children with hemiplegic cerebral palsy, demonstrating statistically and clinically significant change in limb position sense, goal performance and bimanual hand-use. This paper describes a protocol for a Randomised Controlled Trial of Sense© for Kids training, hypothesising that its receipt will improve somatosensory discrimination ability more than placebo (dose-matched Goal Directed Therapy via Home Program). Secondary hypotheses include that it will alter brain activation in somatosensory processing regions, white-matter characteristics of the thalamocortical tracts and improve bimanual function, activity and participation more than Goal Directed Training via Home Program. METHODS AND DESIGN: This is a single blind, randomised matched-pair, placebo-controlled trial. Participants will be aged 6-15 years with a confirmed description of hemiplegic cerebral palsy and somatosensory discrimination impairment, as measured by the sense©_assess Kids. Participants will be randomly allocated to receive 3h a week for 6 weeks of either Sense© for Kids or Goal Directed Therapy via Home Program. Children will be matched on age and severity of somatosensory discrimination impairment. The primary outcome will be somatosensory discrimination ability, measured by sense©_assess Kids score. Secondary outcomes will include degree of brain activation in response to a somatosensory task measured by functional MRI, changes in the white matter of the thalamocortical tract measured by diffusion MRI, bimanual motor function, activity and participation. DISCUSSION: This study will assess the efficacy of an intervention to increase somatosensory discrimination ability in children with cerebral palsy. It will explore clinically important questions about the efficacy of intervening in somatosensation impairment to improve bimanual motor function, compared with focusing on motor impairment directly, and whether focusing on motor impairment alone can affect somatosensory ability. TRIAL REGISTRATION: This trial is registered with the Australian New Zealand Clinical Trials Registry, registration number: ACTRN12618000348257. World Health Organisation universal trial number: U1111-1210-1726.

BACKGROUND: The sense_assess© kids is a standardised, norm-referenced assessment designed to measure the functional somatosensation capacity of the upper limb of children with cerebral palsy. The objective of the current study was to determine if the sense_assess© kids was clinically acceptable to children and youth. METHODS: A questionnaire was completed by participants following administration of the sense_assess© kids by a trained occupational therapist. Twenty-six children with spastic hemiplegic cerebral palsy (aged 6-15 years six months; mean 10 years eight months; 16 boys) were recruited. Participants responded to questions regarding the administration and level of difficulty of the sense_assess© kids using a Q-Sort of 'like' and 'dislike', Likert scales and short answers. Content analysis was applied. RESULTS: Twenty-one of twenty-six children, indicated that they were 'very happy' or 'happy' with the administration process of the sense_assess© kids. Most participants indicated that they liked the sensation they felt in the hand when tested. CONCLUSION: This study has demonstrated the acceptability of sense_assess© kids for the population for whom it is intended.

OBJECTIVE: This study examined the use of the adult neuroscience-based Sense© intervention with children with hemiplegic cerebral palsy (HCP) to improve upper-limb somatosensory discrimination, motor function, and goal performance. METHOD: Seventeen children with HCP (9 boys, 8 girls; mean age = 10.2 yr) participated in this pilot matched-pairs trial with random allocation and 6-mo follow-up (intervention, n = 7; control, n = 10). The intervention group received Sense training 3×/wk for 6 wk (18 hr). Outcome measures included Goal Attainment Scaling, Sense_assess© Kids, and the Assisting Hand Assessment. RESULTS: The intervention group improved in goal performance, proprioception, and bimanual hand use and maintained improvement at 6-mo follow-up. The control group improved in occupational performance by 6-mo follow-up. CONCLUSION: This study established the feasibility of using the Sense intervention in a pediatric setting and adds preliminary evidence to suggest that improving somatosensory function can improve motor function and goal performance among children with HCP.
RESUMEN
INTRODUCTION: Botulinum toxin A (BoNTA) is routine treatment for hypertonicity in children with cerebral palsy (CP). METHODS: This single-blind, prospective, cross-sectional study of 10 participants (mean age 11 years 7 months) was done to determine the relationship between muscle histopathology and BoNTA in treated medial gastrocnemius muscle of children with CP. Open muscle biopsies were taken from medial gastrocnemius muscle and vastus lateralis (control) during orthopedic surgery. RESULTS: Neurogenic atrophy in the medial gastrocnemius was seen in 6 participants between 4 months and 3 years post-BoNTA. Type 1 fiber loss with type 2 fiber predominance was significantly related to the number of BoNTA injections (r = 0.89, P < 0.001). CONCLUSIONS: The impact of these changes in muscle morphology on muscle function in CP is not clear. It is important to consider rotating muscle selection or injection sites within the muscle or allowing longer time between injections.

AIM: To determine if neuromuscular electrical stimulation (NMES) applied to the ankle dorsiflexors during gait improves muscle volume and strength in children with unilateral spastic cerebral palsy (CP). METHOD: Thirty-two children (15 females, 17 males; mean age 10y 8mo, age range 5y 5mo-18y 1mo) with unilateral spastic CP and a Gross Motor Function Classification System of level I or level II were randomly assigned to either the 8-week daily NMES treatment group or control group (usual or conventional treatments). Outcomes at week 8 (post-NMES) and week 14 (carryover) included magnetic resonance imaging for muscle volumes (tibialis anterior, anterior compartment, and gastrocnemius), strength (hand-held dynamometry for isometric dorsiflexion strength and heel raises for functional strength), and clinical measures for lower limb selective motor control. RESULTS: At week 8, the treatment group demonstrated significantly (p<0.05) increased muscle volumes for tibialis anterior, anterior compartment, medial and lateral gastrocnemius, and dorsiflexion strength not only when compared to their baseline values but also when compared to the control group at week 8. At week 14, both tibialis anterior and lateral gastrocnemius volumes in the treatment group remained significantly increased when compared to their baseline values. However, only lateral gastrocnemius volumes had significantly greater values when compared to the control group at week 14. There were no between group differences in the clinical measures for lower limb selective motor control at week 8 and 14. INTERPRETATION: Eight weeks of daily NMES-assisted gait increases muscle volume and strength of the stimulated ankle dorsiflexors in children with unilateral spastic CP. These changes are use-dependent and do not carry over after the 8-week treatment period. Gastrocnemius volume also increased post-treatment with carryover at week 14.

INTRODUCTION: In this study we aimed to characterize muscle composition of the medial gastrocnemius in children with spastic cerebral palsy (SCP) using quantitative ultrasound. METHODS: Forty children with SCP, aged 4-14 years, participated in this study. Children were grouped according to the gross motor function classification system (GMFCS I-V) and compared with a cohort of age- and gender-matched, typically developing children (TD; n = 12). Ultrasound scans were taken of the medial gastrocnemius. Images were then characterized using grayscale statistics to determine mean echo intensity (EI) and the size and number of spatially connected homogeneous regions (i.e., blobs). RESULTS: Significant differences in skeletal muscle composition were found between children with SCP and their TD peers. Children classified as GMFCS III consistently exhibited the highest EI and blob area. CONCLUSIONS: This study demonstrates altered tissue composition in children with SCP visualized using ultrasound. Further work is required to determine the pathophysiology contributing to these alterations in SCP.

BACKGROUND: The purpose of this study was to determine the orthotic and therapeutic effects of daily community applied FES to the ankle dorsiflexors in a randomized controlled trial. We hypothesized that children receiving the eight-week FES treatment would demonstrate orthotic and therapeutic effects in gait and spasticity as well as better community mobility and balance skills compared to controls not receiving FES. METHODS: This randomized controlled trial involved 32 children (mean age 10 yrs 3 mo, SD 3 yrs 3 mo; 15 females, 17 males) with unilateral spastic cerebral palsy and a Gross Motor Function Classification System of I or II randomly assigned to a FES treatment group (n = 16) or control group (n = 16). The treatment group received eight weeks of daily FES (four hours per day, six days per week) and the control group received usual orthotic and therapy treatment. Children were assessed at baseline, post FES treatment (eight weeks) and follow-up (six weeks after post FES treatment). Outcome measures included lower limb gait mechanics, clinical measures of gastrocnemius spasticity and community mobility balance skills. RESULTS: Participants used the FES for a mean daily use of 6.2 (SD 3.2) hours over the eight-week intervention period. With FES, the treatment group demonstrated a significant (p < 0.05) increase in initial contact ankle angle (mean difference 11.9° 95% CI 6.8° to 17.1°), maximum dorsiflexion ankle angle in swing (mean difference 8.1° 95% CI 1.8° to 14.4°) normalized time in stance (mean difference 0.27 95% CI 0.05 to 0.49) and normalized step length (mean difference 0.06 95% CI 0.003 to 0.126) post treatment compared to the control group. Without FES, the treatment group significantly increased community mobility balance scores at post treatment (mean difference 8.3 units 95% CI 3.2 to 13.4 units) and at follow-up (mean difference 8.9 units 95% CI 3.8 to 13.9 units) compared to the control group. The treatment group also had significantly reduced gastrocnemius spasticity at post treatment (p = 0.038) and at follow-up (dynamic range of motion mean difference 6.9°, 95% CI 0.4° to 13.6°; p = 0.035) compared to the control group. CONCLUSION: This study documents an orthotic effect with improvement in lower limb mechanics during gait. Therapeutic effects i.e. without FES were observed in clinical measures of gastrocnemius spasticity, community mobility and balance skills in the treatment group at post treatment and follow-up. This study supports the use of FES applied during daily walking activities to improve gait mechanics as well as to address community mobility issues among children with unilateral spastic cerebral palsy.

PURPOSE: To determine the effects of functional electrical stimulation (FES) on the main impairments affecting gait in children with unilateral spastic cerebral palsy. METHODS: A 20-week, multiple single-subject A-B-A design included a 6-week pre-FES phase, an 8-week FES phase, and a 6-week post-FES phase. Twelve children, aged 5 to 16 years, wore an FES device (the Walk Aide) daily for 8 weeks. Weekly measures included ankle range of motion, selective motor control, dorsiflexion and plantar flexion strength, gastrocnemius spasticity, single-limb balance, Observational Gait Scale (OGS) score, and self-reported toe drag and falls in the community. RESULTS: Compared with the pre-FES phase, the FES phase showed significant improvements in ankle range of motion, selective motor control and strength, and reductions in spasticity, toe drag, and falls, but no change in OGS score. These improvements were maintained during the post-FES phase. CONCLUSIONS: Intermittent, short-term use of FES is potentially effective for reducing impairments affecting gait in children with unilateral spastic cerebral palsy.

BACKGROUND: Prechtl's General Movement Assessment (GMA) at fidgety age (3-5 months) is a widely used tool for early detection of cerebral palsy. Further to GMA classification, detailed assessment of movement patterns at fidgety age is conducted with the Motor Optimality Score-Revised (MOS-R). Inter-rater reliability and agreement are properties that inform test application and interpretation in clinical and research settings. This study aims to establish the inter-rater reliability and agreement of the GMA classification and MOS-R in a large population-based sample. METHODS: A cross-sectional study of 773 infants from birth-cohort in Perth, Western Australia. GMA was conducted on home-recorded videos collected between 12 + 0 and 16 + 6 weeks post term age. Videos were independently scored by two masked experienced assessors. Inter-rater reliability and agreement were assessed using intraclass correlation coefficient and limits of agreement respectively for continuous variables, and Cohen's Kappa and Gwet's Agreement Coefficient, and percentage agreement respectively for discrete variables. RESULTS: The classification of GMA showed almost perfect reliability (AC1 = 0.999) and agreement (99.9 %). Total MOS-R scores showed good-excellent reliability (ICC 0.857, 95 % CI 0.838-0.876) and clinically acceptable agreement (95 % limits of agreement of ±2.5 points). Substantial to almost perfect reliability and agreement were found for all MOS-R domain subscores. While MOS-R domains with higher redundancy in their categorisation have higher reliability and agreement, inter-rater reliability and agreement are substantial to almost perfect at the item level and are consistent across domains. CONCLUSION: GMA at fidgety age shows clinically acceptable inter-rater reliability and agreement for GMA classification and MOS-R for population-based cohorts assessed by experienced assessors.

OBJECTIVE: Intensive rehabilitation aims to improve and maintain functioning in young people who experience disability due to illness or injury. Day rehabilitation may have advantages for families and healthcare systems over inpatient models of rehabilitation. METHODS: This study evaluated the goals and outcomes of a cohort of young people in Western Australia who attended a specialist intensive day rehabilitation programme ("iRehab") at Perth Children's Hospital. Analysis of the iRehab service database was performed. Rehabilitation goals and outcomes were recorded as per the Canadian Occupational Performance Measure (COPM), Children's Functional Independence Measure (WeeFIM), and Goal Attainment Scale (GAS). RESULTS: There were 586 iRehab admissions between August 11, 2011, and December 31, 2018. Admissions were divided by diagnosis: Cerebral Palsy (228, 38.5%), Acquired Brain Injury (125, 21.3%), Spinal Cord Disorders (91, 15.5%), and Other (141, 24.2%). Mean COPM Performance increased by 2.78 points from admission to discharge (95% CI 2.58 to 2.98, pâ<â0.001). Mean COPM Satisfaction was 3.29 points higher at discharge than admission (95% CI 3.07 to 3.51, pâ<â0.001). Mean total WeeFIM score improved by 6.51 points between admission and discharge (95% CI 5.56 to 7.45, pâ<â0.001), and by 3.33 additional points by six months post discharge (95% CI 2.14 to 4.53, pâ<â0.001). Mean GAS T-scores increased by 27.85 (95% CI 26.73 to 28.97, pâ<â0.001) from admission to discharge, and by 29.64 (95% CI 28.26 to 31.02, pâ<â0.001) from admission to six months post discharge, representing improvement consistent with team expectations. CONCLUSION: This study describes a model by which intensive rehabilitation can be delivered in a day rehabilitation setting. A diverse population of young people who experienced disability achieved significant improvements in occupational performance, independence, and goal attainment after accessing intensive day rehabilitation. Improvements were measured in all diagnostic subgroups and were maintained six months after discharge.

AIM: With evidence for an atrophic effect of botulinum toxin type A (BoNT-A) documented in typically developing muscles, this study investigated the immediate morphological alterations of muscles in children with cerebral palsy (CP) after BoNT-A treatment. METHOD: Fifteen children (10 males, five females; age range 5-11y, mean age 8y 5mo, SD 1y 10mo) with spastic diplegic CP [Gross Motor Function Classification System Levels I (n=9) and II (n=6)] receiving BoNT-A injections for spasticity management were included. None of the children was a first-time receiver of BoNT-A. Magnetic resonance imaging and Mimics software assessed muscle volume, timed 2 weeks before and 5 weeks after injection. All participants received BoNT-A bilaterally to the gastrocnemius muscle, and five participants also received BoNT-A bilaterally to the medial hamstring muscles. Functional assessment measures used were the 6-Minute Walk Test (6-MWT), the Timed Up and Go (TUG) test, and hand-held dynamometry. RESULTS: Whilst total muscle group volume of the injected muscle group remained unchanged, a 4.47% decrease in the injected gastrocnemius muscle volume (p=0.01) and a 3.96% increase in soleus muscle volume (p=0.02) was evident following BoNT-A. There were no statistically significant changes in function after BoNT-A as assessed by the TUG. There was also no statistically significant change in distance covered in the 6-MWT. Muscle strength, as assessed using hand-held dynamometry was also not statistically different after BoNT-A treatment. INTERPRETATION: Muscle volume decreases were observed in the injected muscle (gastrocnemius), with synergistic muscle hypertrophy that appeared to compensate for this decrement. The 4% to 5% decrease in the volume of BoNT-A injected muscles are not dramatic in comparison to reports in recent animal studies, and are a positive indication for BoNT-A, particularly as it also did not negatively alter function.

AIM: To investigate the impact of regular exposure to paediatric medical trauma on multidisciplinary teams in a paediatric hospital and the relationships between psychological distress, resilience and coping skills. METHOD: Symptoms of post-traumatic stress disorder, secondary traumatic stress, depression, anxiety, stress, burnout, compassion satisfaction, resilience and coping skills were measured in 54 health professionals and compared with published norms. RESULTS: Participants experienced more symptoms of secondary traumatic stress (P < 0.01), showed less resilience (P = 0.05) and compassion satisfaction (≥ 0.01), more use of optimism and sharing as coping strategies, and less use of dealing with the problem and non-productive coping strategies than comparative groups. Non-productive coping was associated with more secondary traumatic stress (r = 0.50, P = 0.05), burnout (r = 0.45, P = 0.01), post-traumatic stress disorder (r = 0.41, P = 0.05), anxiety (r = 0.42, P = 0.05), depression (r = 0.54, P = 0.01), and stress (r = 0.52, P = 0.01) and resilience was positively associated with optimism (r = 0.48, P = 0.01). Health professionals <25 years old used more non-productive coping strategies (P = 0.05), less 'sharing as a coping strategy' (P = 0.05) and tended to have more symptoms of depression (P = 0.06). CONCLUSION: Paediatric medical trauma can adversely affect a health professional's well-being, particularly those <25 years of age who make less use of positive coping strategies and more use of non-productive coping. These findings will assist the development of effective and meaningful interventions for health professionals working in paediatric hospitals.
