Recovery effect of constraint-induced movement therapy on upper extremity activity of stroke patients with hemiparasis

Objective To explore the rehabilitation effect of constraint-induced movement therapy(CIMT) on upper extremity motor function of stroke patients with hemiparasis.Methods 20 chronic stroke patients were divided into 2 groups: CI group(10 cases),the patients were treated with CIMT for 3 weeks,3 h per day;control group(10 cases),the patients were treated with repetitive occupational therapy for 3 weeks,3 h per day.MAL score and WMFT score were measured in two groups before treatment and 1 week,6 months and 12 months after treatment.Results There were improvement of MAL score in both CI group and control group 1 week after treatment compared with pre-treatment(P0.01),and the scores of MAL on post-treatment 6 months and 12 months were higher than those of pre-treatment in CI group(P0.05,P0.01),but no significant difference in MAL score between post-treatment 6 months and 12 months and pre-treatment in control group;there was no significant difference in WMFT between pre-treatment and post-treatment 1 week,12 months in CI group and control group(P0.05).Conclusion CIMT can significantly increase the use ability on the upper extremity of hemiplegic patients after stroke,but can not improve the motor function of upper extremity in stroke patients.
