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.
