Feasibility of family-directed home-based bimanual intensive therapy combined with modified constraint induced movement therapy (h-BITmCI) in very low and low bimanual functional level: A brief report.

Objective: To examine the feasibility of a home-based hybrid Bimanual-Intensive-Therapy combined with modified Constraint-Induced-Movement-Therapy (h-BITmCI) in children with spastic unilateral cerebral palsy (SUCP) with low and very low bimanual functional level.

Methods: A single-group of 10 children aged 5-8 years old, performed the hybrid home Bimanual-Intensive-Therapy (BIT, 80 hours) combined with modified Constraint-Induced-Movement-Therapy (mCIMT, 20 hours): h-BITmCI. Thus, Bimanual Functional Performance (BFP), Quality of Life (QoL) and expectations from families were measured through the Assisting Hand Assessment, (AHA), Pediatric Quality of Life Inventory, for Cerebral Palsy, (PedsQL v. 3.0, CP) and a specific questionnaire for families for baseline period (week 0), during the treatment phase (week 4 and week 8) and after the intervention (week 10). Repeated measures ANOVA analysis (with post hoc test correction) was used for the BFP and QoL, with a confidence interval (CI) of 95% and with value <.008 considered statistically significant.

Results: Ten children completed the study with an average of 77-hours-BIT and 17-hours-mCIMT. None of the participants dropped out of the study during the follow-up process, and the parents' expectations were fulfilled, indicating high caregiver compliance. During the first 80 hours of BIT, a mean increase of 3.7 AHA units was obtained for the BFP (p = 1.00) and 1.64 points in the QoL (p = 1.00). Clinically relevant changes were observed in the last two weeks (20 hours mCIMT) with a mean increase of 10.6 AHA units in BFP and 6.29 points in QoL (p < .001).

Conclusions: h-BITmCI protocol is feasible to be performed at home with the family's involvement, obtaining the greatest improvements after 100 hours of both therapies. Thus, mCIMT would be a relevant condition to increase the affected upper limb functionality, rather than the dosage used to obtain clinically relevant changes.
