Effects of mirror therapy in conjunction with task-oriented training for improving upper extremity function in post-stroke patients

Objective To explore the effect of mirror therapy in conjunction with task-oriented training on the upper extremity function of post-stroke patients and the possible mechanisms. Methods Twenty-one post-stroke patients were randomly assigned to a treatment group (10 patients) or a control group (ll patients).The patients in the treatment group were given conventional rehabilitation therapy and mirror therapy in conjunction with task-oriented training for 4 weeks.The control group was given only the same conventional rehabilitation treatment as the treatment group and upper extremity task-oriented training for 4 weeks.Both groups trained 1 h/d,5 d/week.Upper-extremity motor ability was assessed using the Fugl-Meyer assessment (FMA) and the Hong Kong version of the functional test for the hemiplegic upper extremity (FTHUE-HK).Ability in the activities of daily living (ADL) was assessed using the Barthel Index (BI) pre-treatment and after 2 and 4 weeks of treatment. Results At the 2nd week and 4th week evaluations,the FMA,FTHUE-HK and BI scores in both groups had all significantly increased compared with pretreatment.The average FMA score in the treatment group increased significantly more than in the control group at week 2,but by the 4th week both FMA and FTHUE-HK scores in the treatment group significantly exceeded those in the control group.There was no significant difference between the two groups in the improvement of their average BI scores. Conclusions Implementing mirror therapy in conjunction with task-oriented training is efficacious.It may promote upper-extremity motor ability in patients with hemiparesis soon after stroke,but there is no definite improvement in ADL ability.
