Adapted version of constraint-induced movement therapy promotes functioning in children with cerebral palsy: a randomized controlled trial.

OBJECTIVE

To evaluate the effects of constraint-induced movement therapy on the use of the affected arm and on daily functioning in children with hemiplegic cerebral palsy.

DESIGN

A single-blinded randomized clinical trial.

SUBJECTS

Sixteen children with cerebral palsy randomized to intervention (n = 8, 4 males, 4 females, mean age 5 years and 6 months) and control groups (n = 8, 4 males, 4 females, mean age 6 years and 7 months).

INTERVENTIONS

Non-affected arm of intervention group was restricted for 10 hours/ day and the affected arm intensively trained for 3 hours/day for two weeks. The intervention protocol included one week of bimanual functional training following constraint therapy. The control group maintained usual rehabilitation throughout the intervention period.

MAIN MEASURES

Pediatric Evaluation of Disability Inventory (self-care domain) and an adapted version of the Jebsen-Taylor test were administered before and after intervention, and at one month follow-up. General linear models tested differences in gain scores and the number needed to treat estimated relative effectiveness of intervention protocol for functional skills and independence in self-care.

RESULTS

Results are reported for 15 children who completed assessments and intervention. Higher gains were observed in the intervention group for functional skills and independence post intervention (d(functional skills) = 1.61, P =0.0134; d(independence)=1.37; P =0.0001) and follow-up (d(functional skills) = 2.08, P =0.004; d(independence) = 0.85; P =0.0016). No group difference in manual dexterity gains was observed. Low indices of number needed to treat (1.75 and 2.33) illustrate clinical relevance of intervention.

CONCLUSIONS

The protocol associating constraint-induced movement therapy and bimanual functional training was effective in promoting daily living functioning among children with cerebral palsy.
