Objectives: The present work was aimed to assess the variation of grip strength with the changes of posture and body joint angles and to establish an optimal body posture and joint angle for the maximum grip strength for adult Bengalee population. Methods: Adult male (n=156) and female (n=224) were involved in this study. The hand grip strength was measured by using Lafayette hand grip dynamometer. Results: The results revealed that male subjects had a significantly greater (p<0.001) grip strength compared to that of female subjects and the highest grip strength was found in standing posture with elbow angle of 90 0 in both adult male and female subjects. Conclusions: From the results it may be recommended that the grip strength of Bengalee population may be measured in standing posture with elbow angle of 90 0 , shoulder angle of 180 0 , and the trunk and wrist in neutral positions to provide maximum force.
