Objective: Improvement of independence of hemiplegics patient especially in balance maintenance is most significant aim of such rehabilitation. Areas of brain lesions in hemiplegics patient and also function of their right and left brain hemispheres were different. We study balance abilities in this two groups of patients.

Materials & Methods: In this comparative and cross sectional study 30 patients with brain stroke were selected with non probability and simple selection in two groups by right hemiplegics (16 objects) and left hemiplegics (14 objects). Ranges of Their age were 30 – 58 years and 6 months passed of stroke. The patient balance ability evaluated by Berg Balance Scale (B.B.S) and Forward Functional Reach (F.F.R) and data were analyzed by use of statistical tests such as: Kolmogorov – Smirnov, Independent T and paired T test.

Results: According to results, average difference of two groups in (B.B.S) test was significant (P=0.030) but average of score of right group (38/36) was more than left group (28/90). But in (F.F.R) test, average difference between two groups wasn’t significant (P=0.841).

Conclusion: According to results, balance especially dynamic balance was related to the side of lesion but in static balance, there was no difference between two groups. According to such results, we can consider good rehabilitation program for improvement of balance of such patients.
