The effect of bilateral activities on the improvement of upper limb function in CVA patients

1. Dept. of Occupational Therapy, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.Background: Bilateral activity is a rehabilitation method for cerebral vascular accident (CVA) patients with proven efficacy. This study investigated the effects of bilateral activities on the affected side upper limb functions in CVA patients.Methods: In this empirical study, 21 CVA patients were assigned into case and control groups. During 8 weeks interventions the case group received bilateral activities in addition to routine treatment, which performed in both groups. Upper limb function was measured using both Fugl- Meyer and Wolf tests at the beginning and end of the 8 week of the study. Data was analyzed using Chi–Square independent and paired sample T-tests.Results: In the case group, function time and sensory motor score were increased significantly after the intervention (p=0.023 and p-0.002 respectively). There was no significant difference between the case and control groups before and after intervention. Significant difference was not seen either in case or in control group in the motor function scores during the study period.Conclusion: Performing bilateral activities could not lead to significant upper limb function improvement. Due to the small sample size and the long time passed after CVA occurring in our study, it seems that more investigations in this filed is necessary.
