A randomized controlled trial of self-regulated modified constraint-induced movement therapy in sub-acute stroke patients.

BACKGROUND AND PURPOSE: Emerging research suggests the use of self-regulation (SR) for improving functional regain in patients post stroke. SR is proposed to produce an added effect to effective modified constraint-induced movement therapy (mCIMT). This study aimed to examine the effect of a self-regulated mCIMT programme (SR-mCIMT) for functional regain in patients with sub-acute stroke.

METHODS: Eighty-six patients completed the trial: SR-mCIMT, n = 29; mCIMT, n = 31; or conventional functional rehabilitation, n = 26. All interventions were 2-week therapist-guided training. Outcome measurements, taken by a blinded assessor, examined arm function [Action Research Arm Test (ARAT), Fugl-Meyer Assessment (FMA)], daily task performance [Lawton Instrumental Activities of Daily Living Scale (Lawton IADL)] and self-perceived arm use in functional tasks [Motor Activity Log (MAL)].

RESULTS: Significant differences were found with the SR-mCIMT outperforming the other groups after the intervention (ARAT, P = 0.006; FMA, Lawton IADL and MAL, all Ps < 0.001). In terms of the carry-over effect, the SR-mCIMT group outperformed in the hand and coordination subscales of ARAT and FMA (P = 0.012-0.013) and the self-perceived quality of arm use (P = 0.002).

CONCLUSION: A combination of SR and mCIMT could produce an added effect in functional regain in patients post stroke.
