Background: Grip and pinch strength are the most important factors affecting the performance of hand. The reaction time is defined as the time interval between the stimulus presentation and the emergence of the response. This study was conducted to investigate the relationship between reaction time, age, gender, and body mass index (BMI) with the results obtained from grip and pinch strength.Methods: This cross-sectional study was performed on 60 staffs of Isfahan University of Medical Sciences, Isfahan, Iran. To determine the reaction time and grip and pinch strength, respectively, reaction timer, dynamometer, and pinch gauge were used.Findings: There was a reverse relationship between simple reaction time and grip and pinch strength of both hands and also between discriminative reaction time with grip and pinch strength in right hand. However, no relationship was observed between discriminative reaction time and grip and pinch strength in left hand. There was no relationship between selective reaction time with grip and pinch strength in both hands. Moreover, with the increase in BMI, the grip strength of left hand and pinch strength of right hand increased. The mean grip and pinch strength of both hands was significantly higher in men compared to women, but there was no significant relationship between age and grip and pinch strength in both hands.Conclusion: In occupations that require high grip and pinch strength, it is recommended to use men and people with high percentage of attention to prevent work-related musculoskeletal disorders (WMSDs).
