Effects of task-specific training on functional ability in children with mild to moderate cerebral palsy

Maintenance of Functional Gains Following a Goal-Directed and FES-Assisted Cycling Program for Children With Cerebral Palsy

PURPOSE

This study investigated whether the functional improvements associated with functional electrical stimulation-assisted cycling, goal-directed training, and adapted cycling in children with cerebral palsy were maintained 8 weeks after the intervention ceased.

METHODS

The intervention (2 × 1-hour supervised sessions and 1-hour home program/week) ran for 8 weeks. Primary outcomes were the Gross Motor Function Measure (GMFM-88) and the Canadian Occupational Performance Measure (COPM). Secondary outcomes included the GMFM-66 and goal scores, 5 times sit-to-stand test (FTSTS), Participation and Environment Measure-Children and Youth (PEM-CY), Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT), and cycling power output (PO). Outcomes were assessed at baseline, 8 and 16 weeks.

RESULTS

Twenty children participated (mean age = 10 years 3 months; SD = 2 years 11 months; Gross Motor Function Classification System II = 5, III = 6, and IV = 9). Improvements were retained above baseline at 16 weeks on the GMFM and COPM. Improvements in cycling PO, PEDI-CAT scores, PEM-CY environmental barriers and FTSTS were also retained.

CONCLUSION

Functional improvements in children with cerebral palsy were retained 8 weeks post-intervention.

Sit-to-stand training for self-care and mobility in children with cerebral palsy: a randomized controlled trial

AIM

To investigate if a sit-to-stand exercise programme for children with cerebral palsy (CP) would improve self-care and mobility.

METHOD

Thirty-eight children with CP (19 males, 19 females; mean age 8y 0mo, SD 2y 4mo, age range 4y 0mo-12y 4mo) classified in Gross Motor Function Classification System (GMFCS) levels III and IV and their caregivers were randomly allocated to sit-to-stand training plus routine physiotherapy (balance and gait training) or routine physiotherapy only (controls). Task-specific sit-to-stand training was completed five times a week for 6 weeks under physiotherapist (twice weekly) and caregiver (three times weekly) supervision. Blinded outcome assessments at week 7 were the self-care and mobility domains of the Functional Independence Measure for Children, Five Times Sit-to-Stand Test (FTSST), and Modified Caregiver Strain Index (MCSI).

RESULTS

The sit-to-stand group self-care increased by 2.2 units (95% confidence interval [CI] 1.3-3.1) and mobility increased by 2.2 units (95% CI 1.4-3.0) compared to the control group. In the sit-to-stand group, the FTSST was reduced by 4.0 seconds (95% CI -4.7 to -3.2) and the MCSI was reduced by 0.8 units (95% CI -1.2 to -0.4) compared to the control group.

INTERPRETATION

A sit-to-stand exercise programme for children with CP classified in GMFCS levels III and IV improved sit-to-stand performance and resulted in small improvements in self-care and mobility, while reducing caregiver strain. What this paper adds Sit-to-stand training improved independence in self-care and mobility for children with cerebral palsy (CP). Home-based sit-to-stand training programmes for children with CP can reduce the burden on supervising caregivers.

Effects of whole-body vibration combined with action observation on gross motor function, balance, and gait in children with spastic cerebral palsy: a preliminary study

This study evaluated the effects of whole-body vibration (WBV) com-bined with action observation on gross motor function, balance, and gait in children with spastic cerebral palsy. The participants were randomized into the WBV combined with action observation (WBVAO) group (n=7) and the WBV group (n=7). The WBVAO group received WBV combined with action observation training, and the WBV group received WBV training for 4 weeks. Both groups received 30 min of training a day, 3 times a week. All participants completed the 5 times sit to stand (FTSTS) test, Timed Up and Go (TUG) test, pediatric reach test, 10-m walk test, 6-min walk test (6MWT), and timed up and down stair (TUDS) test before and after the training intervention. Moreover, the participant’s Gross Motor Function Measure (GMFM) and Pediatric Balance Scale (PBS) scores were assessed. Both the WBVAO and WBV groups demonstrated significant increases in the scores of FTSTS test, GMFM (D and E dimensions), PBS, TUG test, 6MWT, and TUDS test. The WBVAO group improved more significantly compared to the WBV group based on the scores of the FTSTS test, GMFM (D dimension), PBS, 6MWT, and TUDS test. WBV combined with action observation improved lower extremity functional strength, gross motor function, and balance and gait in children with cerebral palsy. These results suggest that WBV combined with action observation is both feasible and suitable for individuals with cerebral palsy.

Effect of task-oriented training on balance and motor function of ambulant children with cerebral palsy

INTRODUCTION AND OBJECTIVES

The study evaluated the effect of task-oriented training (TOT) on the motor function (MF) and balance of ambulant children with cerebral palsy (CP).

MATERIALS AND METHODS

A total of 46 children were randomised into TOT group (n=23) and Control Group (CG [n=23]), but 39 children complete the study. Balance and MF were assessed at baseline, 6th and 12th weeks and 6 weeks post-intervention. Data were analysed with repeated measures ANOVA, Friedman's, Mann-Whitney U, Student's-t and post hoc tests at α≤0.05.

RESULTS

The two groups were comparable in all baseline scores (P>0.05). At the 6th week, significant between-group difference was observed in MF only [TOT=81.9 (18.5); CG=72.8 (19.4)] (P<0.05). There were significant between-group differences in MF [TOT=88.8 (9.4); CG=75.5 (18.5); P<0.05] and balance (TOT=9.4±4.5; CG=13.6±6.9; P<0.05) at the 12th week (P<0.05) and 6 weeks post-intervention (P<0.05).

CONCLUSION

TOT improved the balance and MF of ambulant children with CP.

Effects of a training programme of functional electrical stimulation (FES) powered cycling, recreational cycling and goal-directed exercise training on children with cerebral palsy: a randomised controlled trial protocol

INTRODUCTION

Children with cerebral palsy (CP) experience declines in gross motor ability as they transition from childhood to adolescence, which can result in the loss of ability to perform sit-to-stand transfers, ambulate or participate in leisure activities such as cycling. Functional electrical stimulation (FES) cycling is a novel technology that may provide opportunities for children with CP to strengthen their lower limbs, improve functional independence and increase physical activity participation. The proposed randomised controlled trial will test the efficacy of a training package of FES cycling, adapted cycling and goal-directed functional training to usual care in children with CP who are susceptible to functional declines.

METHODS AND ANALYSIS

Forty children with CP (20 per group), aged 6-8 years and classified as Gross Motor Function Classification System (GMFCS) levels II-IV will be recruited across South East Queensland. Participants will be randomised to either an immediate intervention group, who will undertake 8 weeks of training, or a waitlist control group. The training group will attend two 1 hour sessions per week with a physiotherapist, consisting of FES cycling and goal-directed, functional exercises and a 1 hour home exercise programme per week, consisting of recreational cycling. Primary outcomes will be the gross motor function measure and Canadian occupational performance measure, and secondary outcomes will include the five times sit-to-stand test, habitual physical activity (accelerometry), power output during cycling and Participation and Environment Measure-Children and Youth. Outcomes will be assessed at baseline, postintervention (8 weeks) and 8 weeks following the intervention (retention).

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Griffith University (2018/037) and the Children's Health Queensland Hospital and Health Service (CHQHHS) Human Research Ethics Committee (HREC/17/QRCH/88). Site-specific approval was obtained from CHQHHS research governance (SSA/17/QRCH/145). Results from this trial will be disseminated via publication in relevant peer-reviewed journals.

Daily and Weekly Rehabilitation Delivery for Young Children With Gross Motor Delay: A Randomized Clinical Trial Protocol (the DRIVE Study)

PURPOSE

The proposed project tests the principle that frequency of rehabilitation is an important regulator of therapeutic response in infants.

METHODS

We will randomize 75 infants with cerebral palsy, 6 to 24 months of age and/or Gross Motor Function Classification System levels III to V (higher severity), to determine the short-term and long-term effects of 3 dosing protocols consisting of an identical number of 2-hour sessions of the same motor learning-based therapy applied over a different total number of calendar weeks.

RESULTS AND CONCLUSIONS

The results will inform clinicians, families, and scientists about dosing and will provide needed recommendations for frequency of rehabilitation to optimize motor function and development of young children with cerebral palsy.

Activity training on the ground in children with cerebral palsy: Systematic review and meta-analysis

Purpose: To systematically review the evidence about whether activity training on the ground is effective on activity or participation in children with cerebral palsy. Methods: Randomized controlled trials (RCTs) were searched in databases using relevant keywords. RCTs were included with children (≤18 years) with cerebral palsy who received activity training on the ground only or activity training on the ground combined with another type of physiotherapy. Outcome measures classified as measures of activity or participation according to the International Classification of Functioning, Disability, and Health were analyzed. Results: Nine RCTs (257 participants) were included in this review. Individual studies resulted in conflicting results when activity training on the ground was compared to no intervention. Based on meta-analysis, activity training on the ground was not more effective than no intervention (standardized mean difference [SMD]: 0.18; confidence interval [CI]: -1.49 to 1.86) or other therapies (SMD: -0.09; CI: -0.86 to 0.69) (I² > 75%) on improving activity or participation. Results from a single study demonstrated that activity training on the ground combined with other physiotherapy intervention was not more effective than no intervention (SMD: -0.18 CI: -0.89 to 0.54). Conclusions: The available evidence shows little effect of activity training on the ground on activity or participation in children with cerebral palsy, suggesting that rigorous trials with larger samples and larger "dosage" of activity training on the ground are needed in the future.

Bike skills training for children with cerebral palsy: protocol for a randomised controlled trial

INTRODUCTION

Two-wheel bike riding can be a goal for children with cerebral palsy (CP) and a means of participating in physical activity. It is possible for some children with CP to ride a two-wheel bike; however, currently far fewer can ride compared with their typically developing peers. Evidence supports training targeted towards goals of the child with CP and their family; yet there is little evidence to guide best-practice bike skills training. Task-specific training may lead to attainment of two-wheel bike-specific goals. This study aims to determine if a novel task-specific approach to training two-wheel bike skills is more effective than a parent-led home programme for attaining individualised two-wheel bike-specific goals in independently ambulant children with CP aged 6-15 years.

METHODS AND ANALYSIS

Sixty eligible children with CP (Gross Motor Function Classification System levels I-II) aged 6-15 years with goals relating to riding a two-wheel bike will be randomised to either a novel task-specific centre-based group programme (intervention) or a parent-led home-based programme (comparison), both involving a 1-week intervention period. The primary outcome is goal attainment in the week following the intervention period (T1). Secondary outcomes include: goal attainment and participation in physical activity at 3 months postintervention (T2) and bike skills, attendance and involvement in bike riding, self-perception and functional skills at T1 and T2. Economic appraisal will involve cost-effectiveness and cost-utility analyses. Adherence of clinicians and parents to the intervention and comparison protocols will be assessed. Linear and logistic regression will be used to assess the effect of the intervention, adjusted for site as used in the randomisation process.

ETHICS AND DISSEMINATION

This study was approved by the Human Research and Ethics Committees at The Royal Children's Hospital (#36209). Results will be disseminated via peer-reviewed publications and conference presentations.

Active exercise interventions improve gross motor function of ambulant/semi-ambulant children with cerebral palsy: a systematic review

PURPOSE

Evaluate effectiveness of active exercise interventions for improving gross motor activity/participation of school-aged, ambulant/semi-ambulant children with cerebral palsy (CP).

METHOD

A systematic review was conducted following PRISMA guidelines. Five databases were searched for papers including school-aged children with CP, participating in active, exercise interventions with gross motor outcomes measured at the Activity/Participation level. Interventions with previous systematic reviews were excluded (e.g. hippotherapy). Evidence Level and conduct were examined by two raters.

RESULTS

Seven interventions (34 studies) met criteria. All studies reported on gross motor function, however, a limited number investigated participation outcomes. Strong positive evidence was available for Gross Motor Activity Training (n= 6, Evidence Level II-IV), and Gross Motor Activity Training with progressive resistance exercise plus additional physiotherapy (n = 3, all Evidence Level II). Moderate positive evidence exists for Gross Motor Activity Training plus additional physiotherapy (n = 2, all Evidence Level II) and Physical Fitness Training (n = 4, Evidence Level II-V). Weak positive evidence was available for Modified Sport (n = 3, Evidence Level IV-V) and Non-Immersive Virtual Reality (n = 12, Evidence Level II-V). There was strong evidence against Gross Motor Activity Training plus progressive resistance exercise without additional physiotherapy (n = 4, all Evidence Level II).

INTERPRETATION

Active, performance-focused exercise with variable practice opportunities improves gross motor function in ambulant/semi-ambulant children with CP. Implications for rehabilitation Active exercise interventions improve gross motor function of ambulant/semi-ambulant children with cerebral palsy. Gross Motor Activity Training is the most common and effective intervention. Practice variability is essential to improve gross motor function. Participation was rarely measured and requires further research, particularly in interventions that embed real-world participation opportunities like Modified Sport.

Effectiveness of cognitive orientation to (daily) occupational performance (CO-OP) on children with cerebral palsy: A mixed design

BACKGROUND

Cerebral palsy (CP) is the most common cause of physical disabilities during childhood. Therapeutic interventions mainly focus on impairment reduction to address motor-based difficulties. In contrast, Cognitive Orientation to daily Occupational Performance (CO-OP) is a cognitive approach, providing intervention at the level of activity and participation.

AIMS

This study aims to determine whether the CO-OP approach improves motor skills and achievement in motor-based occupational performance goals in children with CP.

METHODS AND PROCEDURES

In this mixed design research (i.e., a multiple baseline single case experimental design and a one-group pretest-posttest design), five children with CP participated in 12 CO-OP intervention sessions. Repeated measures of motor skills for the multiple baseline single case experimental design were taken using the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP); pre- and post-measures of parent/child perception of performance and satisfaction were identified using the Canadian Occupational Performance Measure (COPM); level of achievement was identified using Goal Attainment Scaling (GAS).

OUTCOMES AND RESULTS

According to the BOTMP results, all children were able to engage in the CO-OP intervention to improve motor performance. Significant differences after treatment were found in both performance and performance satisfaction ratings using the COPM as rated by parents and children. The GAS results showed progress in achievement levels for all children; all goals were achieved or exceeded.

CONCLUSIONS AND IMPLICATIONS

CO-OP intervention can be helpful in improving motor skills and achieving self-identified, motor-based goals in children with CP.

Ability of independently ambulant children with cerebral palsy to ride a two-wheel bicycle: a case-control study

AIM

Limited information exists on the ability of children with cerebral palsy (CP) to ride a two-wheel bicycle, an activity that may improve health and participation. We aimed to describe bicycle-riding ability and variables associated with ability to ride in children with CP (Gross Motor Functional Classification System [GMFCS] levels I-II) compared with children with typical development.

METHOD

This case-control study surveyed parents of 114 children with CP and 87 children with typical development aged 6 to 15 years (115 males, mean age 9y 11mo, standard deviation [SD] 2y 10mo). Kaplan-Meier methods were used to compare proportions able to ride at any given age between the two groups. Logistic regression was used to assess variables associated with ability to ride for children with CP and typical development separately.

RESULTS

The proportion of children with CP able to ride at each level of bicycle-riding ability was substantially lower at each age than peers with typical development (p<0.001). While most children with typical development were able to ride independently by 10 years of age, 51% of children with CP classified as GMFCS level I and 3% of those classified as GMFCS level II had obtained independent riding in the community by 15 years of age. Variables associated with ability to ride for children classified as GMFCS level I were age and parent-rated importance of their child being able to ride.

INTERPRETATION

Some independently ambulant children with CP can learn to ride a bicycle, in particular if they are classified as GMFCS level I. Variables associated with ability to ride deserve consideration in shaping future efforts for the majority of this population who are not yet able to ride.

Task-specific gross motor skills training for ambulant school-aged children with cerebral palsy: a systematic review

OBJECTIVES

The primary objective is to systematically evaluate the evidence for the effectiveness of task-specific training (TST) of gross motor skills for improving activity and/or participation outcomes in ambulant school-aged children with cerebral palsy (CP). The secondary objective is to identify motor learning strategies reported within TST and assess relationship to outcome.

DESIGN

Systematic review.

METHOD

Relevant databases were searched for studies including: children with CP (mean age >4 years and >60% of the sample ambulant); TST targeting gross motor skills and activity (skill performance, gross motor function and functional skills) and/or participation-related outcomes. Quality of included studies was assessed using standardised tools for risk of bias, study design and quality of evidence across outcomes. Continuous data were summarised for each study using standardised mean difference (SMD) and 95% CIs.

RESULTS

Thirteen studies met inclusion criteria: eight randomised controlled trials (RCTs), three comparative studies, one repeated-measures study and one single-subject design study. Risk of bias was moderate across studies. Components of TST varied and were often poorly reported. Within-group effects of TST were positive across all outcomes of interest in 11 studies. In RCTs, between-group effects were conflicting for skill performance and functional skills, positive for participation-related outcomes (one study: Life-HABITS performance SMD=1.19, 95% CI 0.3 to 2.07, p<0.001; Life-HABITS satisfaction SMD=1.29, 95% CI 0.40 to 2.18, p=0.001), while no difference or negative effects were found for gross motor function. The quality of evidence was low-to-moderate overall. Variability and poor reporting of motor learning strategies limited assessment of relationship to outcome.

CONCLUSIONS

Limited evidence for TST for gross motor skills in ambulant children with CP exists for improving activity and participation-related outcomes and recommendations for use over other interventions are limited by poor study methodology and heterogeneous interventions.

Evaluation of group versus individual physiotherapy following lower limb intra-muscular Botulinum Toxin-Type A injections for ambulant children with cerebral palsy: A single-blind randomized comparison trial

This study aimed to evaluate efficacy of group (GRP) versus individual (IND) physiotherapy rehabilitation following lower limb intramuscular injections of Botulinum Toxin-Type A (BoNT-A) for ambulant children with cerebral palsy (CP). Following lower limb BoNT-A injections, 34 children were randomly allocated to GRP (n=17; mean age 7y8m SD 2.0; 13 males; Gross Motor Function Classification System (GMFCS) I=5, II=8, III=4) or IND physiotherapy (n=17; mean age 8y7m SD 2.0; 11 males; GMFCS I=9, II=5, III=3). Primary outcomes were the Canadian Occupational Performance Measure (COPM) and Edinburgh Visual Gait Score (EVGS) assessed at baseline, 10 and 26 weeks post intervention. There were no baseline differences between groups. GRP intervention had greater, but not clinically meaningful, improvement in COPM satisfaction (estimated mean difference EMD 1.7, 95% CI 0.4-3.1; p<0.01) at 26 weeks. Both groups demonstrated clinically significant improvements in COPM performance and satisfaction, but minimal change in quality of gait (EVGS). Six hours of direct physiotherapy (either GRP or IND) with an additional indirect dose (median 16 episodes) of individualized home programme activities following lower limb BoNT-A injections, however, was inadequate to drive clinically meaningful changes in lower limb motor outcomes.

Daily Intervention for Young Children With Cerebral Palsy in GMFCS Level V: A Case Series

PURPOSE

To describe a daily physical therapy (PT) intervention program and outcomes for 2 young children with spastic quadriplegia, Gross Motor Function Classification System (GMFCS) level V, and to evaluate the feasibility of using a daily program in an urban children's hospital outpatient setting.

SUMMARY OF KEY POINTS

Two young children, GMFCS level V, received 2 hours of PT intervention based on motor learning principles 5 days a week for 4 consecutive weeks. Gross Motor Functional Measure (GMFM-66, GMFM-88) and the Bayley Scales of Infant Development, Third Edition, were used as pre- and postoutcome measures. The daily, high intensity intervention was well tolerated. Improvements in motor function, language, and cognitive skills were found.

STATEMENT OF CONCLUSION

A daily PT program appears feasible and may improve overall development in young children with cerebral palsy in GMFCS level V.

Capacity of adolescents with cerebral palsy on paediatric balance scale and Berg balance scale

The Berg balance scale (BBS) and the paediatric balance scale (PBS) are reliable tools for measuring balance ability. However, reports of BBS and PBS scores in adolescent cerebral palsy have been limited. The objectives of this study were to investigate functional balance capacities, as tested with the BBS and PBS in adolescents with cerebral palsy, to compare the total PBS and BBS scores between Gross Motor Function Classification System-Expanded and Revised (GMFCS-E&R) levels and to compare the static balance PBS and BBS scores within each GMFCS-E&R level. Fifty-eight school-aged adolescents with cerebral palsy between the ages of 12 and 18 years with GMFCS-E&R levels of I to IV were recruited. The Kruskal-Wallis test was utilized to compare the median scores for the PBS and BBS between the different GMFCS-E&R levels. Wilcoxon signed-rank tests were performed to examine the differences in the static balance scores between the PBS and the BBS within the same GMFCS-E&R levels. The results reveal that there were differences in the BBS and PBS scores among the four GMFCS-E&R levels. A significant difference was found between the BBS and PBS scores only among the patients with cerebral palsy and level III GMFCS-E&R. The BBS and PBS are valid and reliable tools for clinical examination and for distinguishing between levels of functional balance in adolescents with cerebral palsy.
