Objectives : The purpose of this study was to identify the position and wrist flexion difference of Grip Strength. Methods : The subjects of this study were with total 67 people, They are the students in C college in Ulsan. Position was divided into three categories(standing position, sitting position, lying position). Wrist flexion was divided into four categories(0°, 23°, 50°, 80°). The subjects were measured three times using JAMAR Hydraulic Hand Dynamometer test. The collected materials through that evaluation was analyzed by using SPSS 22.0. Results : Especially sitting position of grip showed relatively high numerical value in the grip strength. 23° Wrist flexion of grip showed relatively high numerical value in the grip strength. Conclusion : This study shows that there are significant differences in the grip strength to position and wrist flexion. Further study is needed to examine impacts of grip position and the age on grip strength. and to identify appropriate grip strength for each hand.
