Resumo
Aim: We compared the efficacy of hand-arm bimanual intensive training (HABIT) in two doses (90 vs. 45 hours) and two schedules of the same dose (90 vs. 2 × 45 hours) on hand and daily functioning. Method: Eighteen children with unilateral cerebral palsy were randomized to receive 6 hours of daily training over 3 weeks, totaling 90 hours (Group 90, n = 9) or receive 6 hours of daily training over 1.5 weeks, totaling 45 hours (Group 2 × 45, n = 9). After 6 months, Group 2 × 45 received an additional 45 hours. Hand (Jebsen–Taylor Test of Hand Function, Assisting Hand Assessment) and daily functioning tests (Canadian Occupational Performance Measure, Pediatric Evaluation of Disability Inventory) were administered before, immediately after, and 6 months after interventions. Results: Both groups demonstrated significant improvements in hand and daily functioning after 90 hours (Group 90) or the first 45 hours (Group 2 × 45), without differences between groups. However, more children from Group 90 obtained smallest detectable differences in the Assisting Hand Assessment. The addition of the second bout of 45 hours (Group 2 × 45) did not lead to further improvements. Conclusions: As this study was powered to test for large differences between groups, future investigations on larger samples will be needed to compare differences at the two dosage levels.
