The purpose of this study was to describe the physical activity level of adolescents with cerebral palsy (CP) and to investigate the associated factors. The physical activity level was measured by means of a questionnaire filled in by the parents of 72 adolescents with CP (12-16 years of age) and expressed in METs. Older age, female gender, and hip dysplasia were significantly associated with a lower level of physical activity. Eighty-nine percent were not physically active enough according to the Dutch norm. Physical activity needs to be promoted, especially among older adolescents with CP (age 14-16 years), girls, and adolescents with hip dysplasia. [ABSTRACT FROM AUTHOR]

Objective: Intrathecal baclofen treatment is used for the treatment of dystonia in patients with severe dyskinetic cerebral palsy; however, the current level of evidence for the effect is low. The primary aim of this study was to provide evidence for the effect of intrathecal baclofen treatment on individual goals in patients with severe dyskinetic cerebral palsy.Methods: This multicenter, randomized, double-blind, placebo-controlled trial was performed at 2 university medical centers in the Netherlands. Patients with severe dyskinetic cerebral palsy (Gross Motor Functioning Classification System level IV-V) aged 4 to 24 years who were eligible for intrathecal baclofen were included. Patients were assigned by block randomization (2:2) for treatment with intrathecal baclofen or placebo for 3 months via an implanted microinfusion pump. The primary outcome was goal attainment scaling of individual treatment goals (GAS T score). A linear regression model was used for statistical analysis with study site as a covariate. Safety analyses were done for number and type of (serious) adverse events.Results: Thirty-six patients were recruited from January 1, 2013, to March 31, 2018. Data for final analysis were available for 17 patients in the intrathecal baclofen group and 16 in the placebo group. Mean (standard deviation) GAS T score at 3 months was 38.9 (13.2) for intrathecal baclofen and 21.0 (4.6) for placebo (regression coefficient = 17.8, 95% confidence interval = 10.4-25.0, p < 0.001). Number and types of (serious) adverse events were similar between groups.Interpretation: Intrathecal baclofen treatment is superior to placebo in achieving treatment goals in patients with severe dyskinetic cerebral palsy.

Purpose state: Orthotic wearing time may be an important confounder in efficacy studies of treatment in children with spastic cerebral palsy (SCP). Most studies measure parent-reported wearing time (WTparent) with questionnaires, but it is questionable whether this yields valid results. This study aims to compare WTparent with objectively measured wearing time (WTobj) in children with SCP receiving orthotic treatment. Method: Eight children with SCP participated in this observational study. For one year, they received knee-ankle-foot orthosis (KAFO) treatment. WTparent was measured using questionnaires. WTobj was measured using temperature sensor-data-loggers that were attached to the KAFOs. The 2.5th and 97.5th percentiles and median of differences between methods (per participant) were used to calculate limits of agreement and systematic differences. Results: There was no systematic difference between WTparent and WTobj (0.1 h per week), but high inter-individual variation of the difference was found, as reflected by large limits of agreement (lower limit/2.5th percentile: −1.7 h/week; upper limit/97.5th percentile: 11.1 h/week). Conclusions: Parent-reported wearing time (WTparent) of a KAFO differs largely from objectively measured wearing time (WTobj) using temperature sensors. Therefore, parent-reported wearing time (WTparent) of KAFOs should be interpreted with utmost care. Low wearing time of orthoses may be a cause of inefficacy of orthotic treatment and incorrect reported wearing time may bias results of efficacy studies. Results of this study show that parent-reported wearing time is not in agreement with objectively measured wearing time. Parent-reported wearing time of KAFOs should be interpreted with utmost care. Objective methods are recommended for measuring orthotic wearing time. [ABSTRACT FROM AUTHOR]

Purpose: To determine the relationship between isometric leg muscle strength and mobility capacity in children with cerebral palsy (CP) compared to typically developing (TD) peers.Method: Participants were 62 children with CP (6–13 years), able to walk with (n = 10) or without (n = 52) walking aids, and 47 TD children. Isometric muscle strength of five muscle groups of the leg was measured using hand-held dynamometry. Mobility capacity was assessed with the 1-min walk, the 10-m walk, sit-to-stand, lateral-step-up and timed-stair tests.Results: Isometric strength of children with CP was reduced to 36–82% of TD. When adjusted for age and height, the percentage of variance in mobility capacity that was explained by isometric strength of the leg muscles was 21–24% (walking speed), 25% (sit-to-stand), 28% (lateral-step-up) and 35% (timed-stair) in children with CP. Hip abductors and knee flexors had the largest contribution to the explained variance, while knee extensors showed the weakest correlation. Weak or no associations were found between strength and mobility capacity in TD children.Conclusion: Isometric strength, especially hip abductor and knee flexor strength, is moderately related to mobility capacity in children with CP, but not in TD children. To what extent training of these muscle groups will lead to better mobility capacity needs further study.Implications for RehabilitationStrength training in children with cerebral palsy (CP) may be targeted more specifically at hip abductors and knee flexors.The moderate associations imply that large improvements in mobility capacity may not be expected when strength increases.

Background. A vicious circle of decreased physical fitness, early fatigue, and low physical activity levels (PAL) is thought to affect children with cerebral palsy (CP). However, the relationship of changes in physical fitness to changes in PAL and fatigue is unclear. Objective. The objective of this study was to investigate the associations among changes in physical fitness, walking-related PAL, and fatigue in children with CP. Design. This study was a secondary analysis of a randomized controlled trial with measurements at baseline, 6 months (after the intervention period), and 12 months. Methods. Twenty-four children with bilateral spastic CP and 22 with unilateral spastic CP, aged 7 to 13 years, all walking, participated in this study. Physical fitness was measured by aerobic capacity, anaerobic threshold, anaerobic capacity, and isometric and functional muscle strength. Walking-related PAL was measured using an ankle-worn activity monitor for 1 week. Fatigue was determined with the Pediatric Quality of Life (PedsQL) Multidimensional Fatigue Scale. Longitudinal associations were analyzed by random coefficient regression analysis. Results. In children with bilateral CP, all fitness parameters showed a positive, significant association with walking-related PAL, whereas no associations between physical fitness and walking-related PAL were seen in children with unilateral CP. No clinically relevant association between physical fitness and fatigue was found. Limitations. Although random coefficient regression analysis can be used to investigate longitudinal associations between parameters, a causal relationship cannot be determined. The actual direction of the association between physical fitness and walking-related PAL, therefore, remains inconclusive. Conclusions. Children with bilateral spastic CP might benefit from improved physical fitness to increase their PAL or vice versa, although this is not the case in children with unilateral CP. There appears to be no relationship between physical fitness and self-reported fatigue in children with CP. Interventions aimed at improving PAL may be differently targeted in children with either bilateral or unilateral CP. [ABSTRACT FROM AUTHOR]

The article focuses on a study which investigates the impact of a six-month physical activity stimulation programme on social participation, self-perception and quality of life in children with cerebral palsy. Topics include paediatric physiotherapy practices, motivational interviewing, home-based physiotherapy and four months of fitness training and efforts of International Convention on the Rights of the Child.

Abstract: Question: In children with cerebral palsy, does a 6-month physical activity stimulation program improve physical activity, mobility capacity, fitness, fatigue and attitude towards sports more than usual paediatric physiotherapy? Design: Multicentre randomised controlled trial with concealed allocation, blinded assessments and intention-to-treat analysis. Participants: Forty-nine walking children (28 males) aged 7–13 years with spastic cerebral palsy and severity of the disability classified as Gross Motor Function Classification System level I–III. Intervention: The intervention group followed a 6-month physical activity stimulation program involving counselling through motivational interviewing, home-based physiotherapy, and 4 months of fitness training. The control group continued their usual paediatric physiotherapy. Outcome measures: Primary outcomes were walking activity (assessed objectively with an activity monitor) and parent-reported physical activity (Activity Questionnaire for Adults and Adolescents). Secondary outcomes were: mobility capacity, consisting of Gross Motor Function Measure-66 (GMFM-66), walking capacity and functional strength, fitness (aerobic and anaerobic capacity, muscle strength), self-reported fatigue, and attitude towards sport (child and parent). Assessments were performed at baseline, 4 months, 6 months and 12 months. Results: There were no significant intervention effects for physical activity or secondary outcomes at any assessment time. Positive trends were found for parent-reported time at moderate-to-vigorous intensity (between-group change ratio=2.2, 95% CI 1.1 to 4.4) and GMFM-66 (mean between-group difference=2.8 points, 95% CI 0.2 to 5.4) at 6 months, but not at 12 months. There was a trend for a small, but clinically irrelevant, improvement in the children's attitudes towards the disadvantages of sports at 6 months, and towards the advantages of sports at 12 months. Conclusions: This physical activity stimulation program, that combined fitness training, counselling and home-based therapy, was not effective in children with cerebral palsy. Further research should examine the potential of each component of the intervention for improving physical activity in this population. Trial registration: NTR2099.

Aims: We aimed to determine factors associated with the longitudinal development of social participation in a Dutch population of individuals with Cerebral Palsy (CP) aged 1-24 years.Methods and Procedures: For this multicentre prospective longitudinal study, 424 individuals with CP aged 1-24 years were recruited from various rehabilitation centers in The Netherlands. Social participation was measured with the Vineland Adaptive Behavior Scales. We assessed associations with age, intellectual impairment, level of gross motor function, gender, type of CP, manual ability, epilepsy, hearing-, visual-, speech impairment and pain, internalizing- and externalizing behavioral problems, type of education and parental level of education. Each individual was measured 3 or 4 times. The time between measurements was 1 or 2 years.Outcomes and Results: Epilepsy and speech impairment were each independently associated with the longitudinal development of social participation. The effects were rather small and did not change with age. Also, a trend was found that children attending special education develop less favorably in social participation.Conclusions and Implications: Our results might provide parents and caregivers with starting points to further develop tailored support for individuals with epilepsy, with speech impairment and/or attending special education at risk for suboptimal social participation.

Purpose: To compare walking activity of children with and without cerebral palsy (CP) between the Netherlands and the United States., Methods: A cross-sectional analysis on walking activity data from an international retrospective comparison study including a convenience sample of 134 walking children aged 7-12 years with spastic CP, classified as Gross Motor Function Classification System (GMFCS) level I (N = 64), II (N = 49) or III (N = 21), and 223 typically developing children (TDC) from the Netherlands and the United States. Walking activity was assessed during a one-week period using a StepWatch™ activity monitor. Outcomes were the daily number of strides, daily time being inactive and spent at low (0-15 strides/min), moderate (16-30 strides/min) and high stride rate (31-60 strides/min). Walking activity was compared between countries using multiple linear regression analyses., Results: Walking activity of TDC was not significantly different between countries. Compared to their American counterparts, Dutch children in GMFCS level I and II showed less walking activity (p < 0.05), whereas Dutch children in GMFCS level III showed more walking activity (p < 0.05)., Conclusion: The absence of differences in walking activity between Dutch and American TDC, and the presence of differences in walking activity between Dutch and American children with CP suggest that between-country differences affect walking activity differently in children with CP., Implications for Rehabilitation: Physical activity of children with CP should be promoted in both the United States and the Netherlands. The between-country differences in walking activity illustrate that apart from the severity of the CP walking activity seems to be influenced by environmental aspects. In the promotion of physical activity, practitioners should pay attention to environmental barriers that families may experience for increasing physical activity.

Purpose: The aim of this study was to describe the physical activity levels of 5- and 7-year-old children with cerebral palsy (CP, n = 97), to compare their physical activity levels with those of typically developing peers (TD, n = 57) and the Dutch recommendation for physical activity, and to investigate the associated factors., Method: The level of physical activity (hours spent on sports and physical activity per week) and contextual factors were assessed with standardised questionnaires., Results: Mean duration of self-reported physical activity for children with CP was 3.4 (+/- 1.9) h/week, which was significantly less than the 5.8 (+/- 2.3) h/week for TD-peers. Ninety-three percent of the children with CP were insufficiently physically active according to the Dutch recommendation for physical activity. Multiple regression analyses showed that younger age and lower educational level of the mother were significantly associated with lower levels of physical activity for children with CP, while severity of CP was not associated with physical activity levels. Twenty-two percent of the parents reported that more facilities in sport and games are required for children with CP., Conclusion: Physical activity is low in young children with CP and needs to be promoted at an early stage.

Objectives: To describe the course of gross motor function over 2 years in children with cerebral palsy (CP) aged 9 to 15 years, and to investigate its relationship with impairments and age., Design: Prospective cohort study., Setting: Rehabilitation department of a university medical center in the Netherlands., Participants: Seventy boys and 40 girls with CP (mean age +/- standard deviation, 11.2+/-1.7y)., Interventions: Not applicable., Main Outcome Measure: The Gross Motor Function Measure (GMFM)., Results: GMFM item scores were stable over the 2 years for the whole group. No difference was found in the course of GMFM item scores between the Gross Motor Function Classification System (GMFCS) levels. We found significant differences in the course of GMFM item scores (corrected for GMFCS) for the different levels of limb distribution, selective motor control, muscle strength, range of motion in the hip and knee, spasticity of the hamstrings, and type of education. There were significantly larger decreases in the more severely affected children. Multivariable analysis showed that a poor selective motor control was the most important determinant of a less favorable course of gross motor function., Conclusions: Some impairment characteristics may be used to identify children who are at risk for deterioration in gross motor function, and may serve as a guide for interventions.
