Abstract

Backgrounds: Grip strength is a specific part “muscular strength” of upper limb required to be used in pulling or grasping an object. Handgrip strength assessment is importance in determining the effectiveness of different treatment strategies or effects of different procedures. As studies on the effect of elbow and wrist positions on grip strength remain controversial. Objectives: This study aimed to evaluate the effect of elbow and wrist joint positions on grip strength and to find advantageous position for powerful grip to improve grasp function. Methods: This study included 178 (110 males and 68 females) healthy normal subjects with group age group of 20 – 39 years at Hong Bang International University. A standard adjustable hydraulic hand Jamar Dynamometer was used for measuring grip strength of various positions of elbow and wrist. Anthropometric index information is collected by direct measurement. Results: The result of the study showed that the elbow and wrist positions had impact on the grip strength when considered individually (p<0,001). The results of ANOVA findings indicated differences (p<0.001) in grip strength between elbow 90o flexion and full extended with respect to writs in neutral and 30o extension. Conclusions: This study showed different effects on grip strength when individuals use different hand with variations in elbow and wrist positions to grip. Grip strength   in dominant hand was maximum with elbow in full extension and wrist in neutral.
