Upper Extremity Strength and Strength Relationships Among Young Women

Abstract
The static strength of 10 upper extremity muscle groups of 3 1 young women was tested bilaterally to gain a preliminary estimate of the strength of the muscle groups and the relationship between the strength of the muscle groups. Strength was measured using a hand-held dynamometer. Descriptive statistics were calculated for the measurements obtained. Inferential statistics revealed a significant difference in strength between the left and right side for only three muscle groups. The only antagonistic muscle groups that differed significantly on both the left and right side were the elbow flexor and extensor muscles. The strength of each muscle group was significantly related to the strength of every other muscle group on each side. The strength values and strength relationships reported herein should prove useful to clinicians testing the upper extremity strength of young women. J Orthop Sports Phys Ther 1986;8(3):128-133.
