Abstract

Purpose：The purpose of this study are analysis characteristic of grasping power with each different elbow flexion degree and grasping power with each different elbow each different hand position and announcement. Methods：Measuring about 10cm wide open position with both feet for each elbow in the line positions of the $0^{\circ}$, $45^{\circ}$, $90^{\circ}$, $135^{\circ}$, and forearm position of supination, mid position, pronation is of the order. Results：The averge position of maximal grip strength was $0^{\circ}$ of elbow flexion with mid position in male and $90^{\circ}$ of elbow flexion with mid position in female. Grip strength in change of wrist position according to elbow flexion was significant difference(P<0.05). Grip strength in change of wrist position according to elbow flexion by sex was significant difference(P<0.05) Conclusion：When the elbow has flexion with $0^{\circ}$, $45^{\circ}$, $90^{\circ}$, $135^{\circ}$ then grasping power has a intimate relation with forearm position. Grasping power with forearm supination, pronation and mid position also has a intimate relation with elbow flexion.
