Comparing the effects of modified constraint-induced movement therapy and bimanual training in children with hemiplegic cerebral palsy mainstreamed in regular school: A randomized controlled study.

PURPOSE: The aim of this study was to compare the effects of modified constraint-induced movement therapy (mCIMT) and bimanual training (BIT) based on the International Classification of Functioning, Disability, and Health, Children and Youth (ICF-CY) conceptual framework.

RESEARCH METHOD: A total of 32 children (mean age 10.43 years [SD 2.9 years]; 15 girls, 17 boys) whose functional motor and communication levels, according to the Manual Ability Classification System, Gross Motor Function Classification System, and Communication Function Classification System, changed between level I and III were randomly distributed to one of the mCIMT or BIT groups with equivalent dosing frequencies and intensities (10 weeks, 3 days/week, 2.5 h/day). Upper extremity body function outcomes (handheld dynamometer), activity outcomes (Quality of Upper Extremity Skills Test, The Children's Hand-use Experience Questionnaire, ABILHAND-Kids, Pediatric Upper Extremity Motor Activity Log), and participation outcomes (Child and Adolescent Scale of Participation) were assessed before and after treatment, and at 16 weeks postintervention. The clinical trial number of the study is NCT04577391.

RESULTS

mCIMT resulted in more significant improvements in all outcomes than BIT at the immediate postintervention period (T2), which were maintained in the mCIMT group throughout the 16-week postintervention period (p<0.001; dmCIMT > dBIT).

CONCLUSION

The potential advantage of mCIMT versus BIT is the larger short-term effect sizes (ESs) and the more sustainable improvements.
