A Pilot Feasibility Study on the Use of Dual-Joystick-Operated Ride-on Toys in Upper Extremity Rehabilitation for Children with Unilateral Cerebral Palsy

Children with unilateral cerebral palsy (UCP) require task-oriented practice several hours per week to produce meaningful gains in affected upper extremity (UE) motor function. Clinicians find it challenging to provide services at the required intensity and sustain child engagement. This pilot study assessed the acceptance and utility of a child-friendly program using dual-joystick-operated ride-on toys incorporated into an intensive UE rehabilitation camp. Eleven children with UCP between four and 10 years received ride-on-toy navigation training for 20-30 min/day, five days/week, for three weeks as part of camp programming. We report session adherence and percent time children spent in task-appropriate attention/engagement across sessions. The overall effects of camp programming on children's motor function were assessed using the Shriner's Hospital Upper Extremity Evaluation (SHUEE) from pretest to posttest and using training-specific measures of bimanual UE use and navigational accuracy. Children showed excellent adherence and sustained task-appropriate engagement across sessions. The combined program led to improved navigational accuracy (p-values ≤ 0.007) as well as spontaneous affected UE use during bimanual activities outside the training context (p < 0.001). Our pilot study provides promising evidence for using modified, commercially available ride-on toys to incentivize rehabilitation and boost repetitive, task-oriented UE practice among children with UCP.

Upper limb manual training for children with cerebral palsy: A systematic review and network meta-analysis of randomized controlled trials

OBJECTIVE

There are different upper limb manual training protocols, namely constraint-induced movement therapy, modified constraint-induced movement therapy, hand-arm bimanual intensive training, hand-arm bimanual intensive training including lower extremity, action observation training, and mirror therapy, available for improving functional outcomes in children with cerebral palsy. However, the effect and priority of these strategies remain unclear.

DATA SOURCES

We searched the PubMed, Cochrane Library, and Embase databases for relevant articles from inception to October 12, 2022.

REVIEW METHODS

To assess the effect and priority of different strategies of upper limb manual training protocols through a systematic review and network meta-analysis of randomized controlled trials.

RESULTS

We included 22 randomized controlled trials in this network meta-analysis. The ranking probability and standard mean differences with 95% credible intervals of the comparison between placebo and other forms of upper limb manual training were as follows: mirror therapy = 2.83 (1.78, 3.88), hand-arm bimanual intensive training including the lower extremity = 0.53 (0.09, 0.96), constraint-induced movement therapy = 0.44 (0.18, 0.71), hand-arm bimanual intensive training = 0.41 (0.15, 0.67), modified constraint-induced movement therapy = 0.39 (0.03, 0.74), and action observation training = 0.18 ( - 0.29, 0.65). No significant inconsistency was noted between the results of direct and indirect comparisons.

CONCLUSION

We suggest that mirror therapy could be the upper limb manual training protocol of choice for improving functional outcomes in patients with cerebral palsy.

The Efficacy of Two Models of Intensive Upper Limb Training on Health-Related Quality of Life in Children with Hemiplegic Cerebral Palsy Mainstreamed in Regular Schools: A Double-Blinded, Randomized Controlled Trial

BACKGROUND

Children with hemiplegic cerebral palsy (CP) are at risk of reduced upper limb function and poorer quality of life than their typically developing peers. Although upper limb impairments have potential negative impact on the health-related quality of life (HRQOL) in children with hemiplegic CP, the efficacy of upper limb rehabilitation approaches aiming to improve upper limb impairments on HRQOL has not been adequately investigated.

OBJECTIVE

This study compares the efficacy of two modes of activity-based upper limb rehabilitation (modified constraint-induced movement therapy [mCIMT] and bimanual training [BIM]) on HRQOL outcomes in children with hemiplegic CP mainstreamed in regular schools.

METHODS

Thirty children with hemiplegic CP aged between 7 and 11 years (mean age 8.53 ± 1.54 years) who had functional ability levels of I-III according to the Manual Ability Classification System (MACS), Gross Motor Classification System (GMFCS), and Communication Function Classification System (CFCS) were randomly assigned to receive mCIMT or BIM training. Result: Both mCIMT and BIM yielded statistically significant improvements in all HRQOL domains immediately after the 10-week interventions (P < .001), which were retained at 16 weeks.

CONCLUSION

While there were some differences in the intervention effects, both of these upper limb rehabilitation approaches based on intensive unimanual or bimanual activity may be beneficial for improving perceived life satisfaction related to physical activity, general mood, family, friends, and school among children with hemiplegic CP mainstreamed in regular schools.

Bilateral Sensorimotor Cortical Communication Modulated by Multiple Hand Training in Stroke Participants: A Single Training Session Pilot Study

Bi-manual therapy (BT), mirror therapy (MT), and robot-assisted rehabilitation have been conducted in hand training in a wide range of stages in stroke patients; however, the mechanisms of action during training remain unclear. In the present study, participants performed hand tasks under different intervention conditions to study bilateral sensorimotor cortical communication, and EEG was recorded. A multifactorial design of the experiment was used with the factors of manipulating objects (O), robot-assisted bimanual training (RT), and MT. The sum of spectral coherence was applied to analyze the C3 and C4 signals to measure the level of bilateral corticocortical communication. We included stroke patients with onset <6 months (n = 6), between 6 months and 1 year (n = 14), and onset >1 year (n = 20), and their Brunnstrom recovery stage ranged from 2 to 4. The results showed that stroke duration might influence the effects of hand rehabilitation in bilateral cortical corticocortical communication with significant main effects under different conditions in the alpha and beta bands. Therefore, stroke duration may influence the effects of hand rehabilitation on interhemispheric coherence.

Process Evaluation of Home-based Bimanual Training in Children with Unilateral Cerebral Palsy (The COAD-study): A Mixed Methods Study

PURPOSE

To evaluate the processes and factors that influenced implementation and impact of a home-based bimanual training program in children with unilateral cerebral palsy aged 2 through 7 years.

METHODS

The program encompassed bimanual task-specific training (3.5 hours/week for 12 weeks) adopting either implicit or explicit motor learning. A therapist and remedial educationalist coached parents. This mixed methods study included course attendance monitoring, questionnaires, registration form, video analysis, interviews, focus group discussion, and drop-out monitoring.

RESULTS

Fourteen families participated. The program was not fully implemented as intended. Parents positively experienced the training and were well able to provide it. The program was demanding for the children and time-consuming for parents. Several components positively contributed to the program: task-analysis, instructional videos, and coaching by a therapist and remedial educationalist. Several modifications to the program were proposed.

CONCLUSION

Home-based bimanual training forms a demanding but promising therapeutic approach with potential for optimization.

Effect of Home-based Bimanual Training in Children with Unilateral Cerebral Palsy (The COAD-study): A Case Series

Purpose: To explore the child- and parent-related effects of home-based bimanual training in children with unilateral cerebral palsy.Methods: Case series of 14 children (2-7 years) who completed goal-oriented task-specific training for 3.5 hours/week for 12 weeks by a program adopting implicit (n = 5) or explicit (n = 9) motor learning. A therapist and remedial educationalist coached parents. Progression on bimanual goals (Canadian Occupational Performance Measure (COPM)) and therapy-related parental stress (interviews) were of primary interest. Data were collected at baseline (T0), halfway through and at the end of training (T1 and T2), and after 12 weeks (T3).Results: On the COPM performance scale a clinically relevant change was seen in 50% (7/14), 86% (12/14), and 85% (11/13) of the children, at T1, T2, and T3, respectively. Some parents indicated that they had experienced stress because of the training intensity.Conclusion: The child- and parent-related effects of the home-based bimanual training programs are encouraging.

Including a Lower-Extremity Component during Hand-Arm Bimanual Intensive Training does not Attenuate Improvements of the Upper Extremities: A Retrospective Study of Randomized Trials

Hand-Arm Bimanual Intensive Therapy (HABIT) promotes hand function using intensive practice of bimanual functional and play tasks. This intervention has shown to be efficacious to improve upper-extremity (UE) function in children with unilateral spastic cerebral palsy (USCP). In addition to UE function deficits, lower-extremity (LE) function and UE-LE coordination are also impaired in children with USCP. Recently, a new intervention has been introduced in which the LE is simultaneously engaged during HABIT (Hand-Arm Bimanual Intensive Therapy Including Lower Extremities; HABIT-ILE). Positive effects of this therapy have been demonstrated for both the UE and LE function in children with USCP. However, it is unknown whether the addition of this constant LE component during a bimanual intensive therapy attenuates UE improvements observed in children with USCP. This retrospective study, based on multiple randomized protocols, aims to compare the UE function improvements in children with USCP after HABIT or HABIT-ILE. This study included 86 children with USCP who received 90 h of either HABIT (n = 42) or HABIT-ILE (n = 44) as participants in previous studies. Children were assessed before, after, and 4-6 months after intervention. Primary outcomes were the ABILHAND-Kids and the Assisting Hand Assessment. Secondary measures included the Jebsen-Taylor Test of Hand Function, the Pediatric Evaluation of Disability Inventory [(PEDI); only the self-care functional ability domain] and the Canadian Occupational Performance Measure (COPM). Data analysis was performed using two-way repeated-measures analysis of variance with repeated measures on test sessions. Both groups showed similar, significant improvements for all tests (test session effect p < 0.001; group × test session interaction p > 0.05) except the PEDI and COPM. Larger improvements on these tests were found for the HABIT-ILE group (test session effect p < 0.001; group × test session interaction p < 0.05). These larger improvements may be explained by the constant simultaneous UE-LE engagement observed during the HABIT-ILE intervention since many daily living activities included in the PEDI and the COPM goals involve the LE and, more specifically, UE-LE coordination. We conclude that UE improvements in children with USCP are not attenuated by simultaneous UE-LE engagement during intensive intervention. In addition, systematic LE engagement during bimanual intensive intervention (HABIT-ILE) leads to larger functional improvements in activities of daily living involving the LE.

Hand and Arm Bimanual Intensive Therapy Including Lower Extremity (HABIT-ILE) in Children With Unilateral Spastic Cerebral Palsy: A Randomized Trial

BACKGROUND

Intensive bimanual training results in more improvement in hand function in children with unilateral spastic cerebral palsy (USCP) than lower intensity conventional interventions. However, it is not known whether combined upper and lower extremity training in an intensive protocol is more efficacious for upper and lower functional abilities than conventional therapies provided in usual customary care.

OBJECTIVE

To determine the efficacy of Hand and Arm Bimanual Intensive Therapy Including Lower Extremity (HABIT-ILE) for children with USCP.

METHODS

Twenty-four children with USCP were randomized into 2 groups: an immediate HABIT-ILE group (IHG, initially receiving HABIT-ILE, 10 days = 90 hours), and a delayed HABIT-ILE group (DHG), which continued their conventional/ongoing treatment for an intended total duration of 90 hours. In phase 2, children in the DHG were crossed over to receive HABIT-ILE and children of the IHG were followed in their ongoing conventional therapy. Children were assessed using the Assisting Hand Assessment (AHA, primary outcome), the ABILHAND-Kids, and the Pediatric Evaluation of Disability Inventory. Dexterity (Box and Blocks Test [BBT]) and pinch strength were also measured. Locomotor abilities were assessed with Six-Minute Walk Test (6MWT, primary outcome) and ABILOCO-kids. Social participation was measured with the Assessment of Life-HABITs.

RESULTS

A 2 (groups) × 3 (test sessions) analysis of variance indicated significant improvements for primary outcomes (AHA, P < .001; 6MWT, P = .002) and all secondary assessments except BBT, step length and bodyweight distribution following HABIT-ILE, but not conventional therapy.

CONCLUSION

The findings suggest that combined upper and lower extremity in an intensive training protocol may be efficacious for improving both upper and lower extremity function in children with USCP.

Comparison of Structured Skill and Unstructured Practice During Intensive Bimanual Training in Children With Unilateral Spastic Cerebral Palsy

Background High-intensity training aims to improve hand function in children with unilateral spastic cerebral palsy (USCP). However, the extent to which skill training is required is not known. Objectives To compare the effects of intensive bimanual training with and without structured progression of skill difficulty, on manual dexterity, bimanual hand use, daily functioning, and functional goals in children with USCP. Method Twenty-two children were randomized to structured practice group (SPG) or unstructured practice group (UPG), and received 6 h/d training during 15 days. Children from the SPG were engaged in fine and gross motor bimanual activities, with skill progression and goal training. Children from UPG performed the same activities without skill progression or goal training. Participants were evaluated before, immediately and 6 months after training by a physical therapist blinded to group allocation. The primary outcomes were the Jebsen-Taylor Test of Hand Function (JTTHF) and Assisting Hand Assessment (AHA). Secondary outcomes included the Canadian Occupational Performance Measure (COPM), Pediatric Evaluation of Disability Inventory (PEDI), and ABILHAND-Kids. Results Both groups showed similar improvements in the JTTHF, AHA, ABILHAND-Kids, COPM-satisfaction, and PEDI (P < .05). A significant interaction in the COPM-performance scale (P = .03) showed superior improvements of the SPG immediately, but not 6 months, after the intervention.

CONCLUSIONS

Children from both groups demonstrated improvements in dexterity and functional hand use. This suggests that for intensive bimanual approaches, intensive training at such high doses may not require structured practice to elicit improvements. However, there may be immediate added benefit of including goal training.
