Aims:The aim of the study was to evaluate the effects of body mass index on grip and pinch strength in various position of the dominant side amongst young adults.Method: This study included 150 healthy subjects between the age group of 19-33 yrs.Handgrip strength of the subject was measured using a jamar dynamometer.and pinch strength of the subject was measured using a B&L pinch gauge.Grip strength was measurement in various position in shoulder and elbow.And the pinch strength was measurement in various elbow position.Results: There is significant correlation between body mass index and pinch and grip strength in dominant hand girls and boys. Conclusion:There is a significant difference between hand grip and pinch grip in various position.And there is also significant difference in between standing and sitting posture of pinch grip.
