Aim: To investigate long-term development of hand function after repeated botulinum neurotoxin A (BoNT-A) and occupational therapy at a young age.Method: Twenty children with unilateral spastic cerebral palsy (CP) (14 males, six females; median inclusion age 3y 1mo, range 1y 11mo-4y 3mo) participated in this longitudinal study. Ten children received occupational therapy after a randomized controlled trial and 10 repeated BoNT-A plus occupational therapy during 1-year. The Assisting Hand Assessment (AHA) and active supination, assessed the following 3 years. The assessments were compared with data from a reference group to investigate development over time.Results: The improvement in AHA (7.5 AHA units) after BoNT-A plus occupational therapy was maintained at final follow-up. The occupational therapy group, unchanged after 1-year, improved by 5 AHA units (96% confidence interval [CI] 2-10), thus there was no difference between the groups. Median active supination increased in comparison with the reference group. In the BoNT-A/occupational therapy group, 9 out of 10 (97.85% CI 45 115) children improved in active supination. In the occupational therapy group, 7 out of 10 (97.85% CI -2 to 68) children improved in active supination. No correlation between active supination and AHA was found.Interpretation: Bimanual performance achieved after BoNT-A plus occupational therapy was maintained, while it increased by follow-up in the occupational therapy group, suggesting that combined intervention gave earlier access to bimanual skills. Active supination was unrelated to AHA.What This Paper Adds: Children whose bimanual performance improved after botulinum neurotoxin A and/or occupational therapy, maintained skills or progressed during follow-up. Bimanual performance increased with age, similar to a quality-register reference group. Increased active supination after intervention improved at follow-up but was not related to bimanual performance. [ABSTRACT FROM AUTHOR]

Aim: To test the hypothesis that improvements in gait and function following individualized interdisciplinary interventions consisting of physical therapy, orthotics, spasticity management, and orthopaedic surgery using instrumented gait analysis are superior to 'usual care' in children with cerebral palsy (CP).Method: This was a prospective, single-blind, parallel-group, randomized controlled trial investigating the effectiveness of interventions based on the use of gait analysis. Primary outcome was gait (Gait Deviation Index) and secondary outcomes were walking and patient-reported outcome measures of function, disability, and health-related quality of life. Follow-ups were done at 26 weeks (questionnaires) and at the primary end point of 52 weeks (all outcomes).Results: Sixty participants with CP (39 males, 21 females, mean age 6y 10mo, standard deviation 1y 3mo, range 5y-9y 1mo) in Gross Motor Function Classification System levels I or II, were randomized to interventions with or without gait analysis. No significant or clinically relevant between-group differences in change scores of the primary or secondary outcomes were found. The recommended categories of interventions were dominated by non-surgical interventions and were applied in 36% to 86% of the participants.Interpretation: Interventions using gait analysis were not superior to 'usual care' on gait, walking, or patient-reported outcomes in a sample of relatively young and independently walking children with CP not expected to need surgery.What This Paper Adds: Gait analysis in children with cerebral palsy in Gross Motor Function Classification System levels I or II recommends interdisciplinary interventions. Compliance to interventions recommended after gait analysis was low. No statistically significant advantages were identified for the intervention group versus the control group.

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.

Aim: To investigate the responsiveness of the ACTIVLIM-CP questionnaire after two evidence-based interventions for children with cerebral palsy (CP).Method: Seventy-five children with CP either participated in an intensive motor-skill learning intervention (hand-arm bimanual intensive therapy including lower extremities [HABIT-ILE], n=47) or received botulinum neurotoxin-A (BoNT-A) injection(s) into lower extremities combined with conventional physical therapy (n=28). All children were assessed three times: at baseline (T0 ; before HABIT-ILE/the day of BoNT-A injection), at T1 (last day of HABIT-ILE/6wks after BoNT-A injection), and at follow-up (T2 ; 3-4mo after the beginning of intervention). Parents completed ACTIVLIM-CP and three other activity questionnaires. Responsiveness was analysed using group (based on intervention), subgroup (based on gross motor function level), and individual approaches.Results: For the HABIT-ILE group, significant improvements in ACTIVLIM-CP were observed for the T0 -T1 period (p<0.001) but not for the T1 -T2 period. No significant changes were found in the BoNT-A group during assessments (p=0.84). In the subgroup analysis for the HABIT-ILE group (T0 -T1 ), greater changes were demonstrated for children in Gross Motor Function Classification System levels III and IV (p<0.001, effect size=1.36). The individual approach was congruent with the group approach.Interpretation: ACTIVLIM-CP demonstrated high responsiveness after HABIT-ILE, showing that this scale may be used to investigate global activity performance in clinical trials focusing on improving daily life activities.What This Paper Adds: Good responsiveness of ACTIVLIM-CP questionnaire during intensive motor-skill learning intervention. Higher responsiveness for children in Gross Motor Function Classification System (GMFCS) levels III and IV versus I and II after intensive intervention. ACTIVLIM-CP is useful to identify children improving their performance after botulinum neurotoxin-A injection. [ABSTRACT FROM AUTHOR]

Aim: To determine whether intrathecal baclofen (ITB) therapy improves performance and performance satisfaction in goal areas identified by patients' parents.Method: This study formed part of an ongoing multicentre national audit involving six paediatric ITB pump implant centres across Australia. The Canadian Occupational Performance Measure was the primary outcome measure utilized at baseline, 6 months, and 12 months after pump implants in paediatric patients receiving ITB therapy for the first time between 31st December 2009 and 31st December 2014.Results: Twenty-five children had goals identified (mean age 11y 1mo), 19 had a diagnosis of cerebral palsy and 22 were at Gross Motor Function Classification System level IV, V, or equivalent. Strong evidence for an improvement in goal performance (2.33, 95% CI 1.70, 2.96, p<0.001) and performance satisfaction scores (3.08, 95% CI 2.28, 3.88, p<0.001) were demonstrated at 6 months, compared to baseline. The differences were clinically significant and were sustained to 12 months.Interpretation: ITB therapy in paediatric patients with hypertonia results in clinically significant improvements in average performance and performance satisfaction scores.What This Paper Adds: The most commonly identified goals of parents of children treated with intrathecal (ITB) therapy were: improving ease of dressing, positioning, and transfers. ITB therapy is effective in improving performance and performance satisfaction in children with hypertonia. Score improvements are mainly evident within the first 6 months of therapy.

Aim: To identify a cohort of children with cerebral palsy (CP) from hospital data; determine the proportion that participated in standardized educational testing and attained a score within the normal range; and describe the relationship between test results and motor symptoms.Method: This population-based retrospective cohort study used data from New South Wales, Australia. We linked hospital data for children younger than 16 years of age admitted between 1st July 2000 and 31st March 2014 to education data from 2009 to 2014. Hospital diagnosis codes were used to identify a cohort of children with CP (n=3944) and describe their motor symptoms. Educational outcomes in the CP cohort were compared with those among children without CP.Results: Of those with educational data (n=1770), 46% were exempt from reading assessment because of intellectual or functional disability, 7% were absent or withdrawn from testing and 47% participated in testing. About 30% of all children with educational data had test scores in the normal range. The proportion was greatest among those with hemiplegia (>40%) and lowest among those with tetraplegia (<10%).Interpretation: One-third of children with CP participated in standardized testing and achieved a result in the normal range. The proportions were lower in children with more severe motor symptoms.What This Paper Adds: From 2009 to 2014, most Australian children with cerebral palsy (CP) attended a mainstream school. The rate of disability-related exemption from standardized educational testing was almost 50%. Thirty per cent of children with CP achieved educational scores in the normal range.
