Purpose In this study, we were trying to find out effect of improved trunk control and ADL performance through upper limb training as functional reaching in the upper limb. Method We selected 12 stroke patients randomly in hospital, who have a problem with their upper limb, trunk and ADL performance. But we excluded 1 stroke patient to discharge in study period suddenly. The patients were divided into conservative training group and the functional reaching training group. In conservative group, we applied only general occupational therapy, but in functional reaching training group, we applied upper limb training as functional reaching instead of general occupational therapy. To compare each group we used several assessment tools such as MBI, total TIS, static TIS, dynamic TIS and coordinative TIS. Result We reached out results as follows. 1) In functional reaching training group, there was statistically reliable in total TIS, dynamic TIS, MB!. 2) We compared changes in before and after training and found that there was relationship among assessment outcomes. Especially, static TIS showed relationship on both group. Conclusion Functional reaching training has influences on trunk control and ADL performance. Especially, functional reaching training group offered static trunk control ability more than conservative training group.
