Objective : The purpose of this study was to investigate the effect of mental practice on the upper extremity and ADL(Activity Daily Living) in person with stroke. Methods : Participants were randomly allocated to two groups: experimental(n=7) and control(n=7). The patients were randomly divided into an experimental group and a control group. Both groups participated in mental practice program 5 session 30 minutes per week for 4 weeks. The Upper extremity was measured by MFT, BBT, MAL(Amount of Use; AOU, Quality of Movement; QOM), Grip strengthening. Jae-Shin(2005) development activities of daily living tests were evaluated using. Result : As a result of the analysis of the comparison of the differences between two groups, in respect the areas of upper extremity function, ADL, there were significant differences. Experimental group assessment of upper extremity function and ADL examination showed significant difference(p<.05). Scores showed the improvement in the control group at all assessment items or MAL(quality of movement) items only, showed significant changes. Conclusion : This study demonstrated the effectiveness of mental practice program training on the functional recovery of stroke patients by showing an improved performance of upper-limb functionality, activities of daily living.
