Abstract

The purpose of this study was to investigate the correlation between muscle power of the wrist flexor muscles and muscle strength according to grip type, such as the strength difference between a two-finger pinch grip and four-finger pinch grip. After the preliminary study, six subjects who agreed to participate in this study were recruited and the experiment was conducted. The power of the wrist flexor was measured using a digital manual muscle tester in the sitting position, and the grip strength according to the grip type was measured with a digital grip dynamometer. Spearman's nonparametric test was used to determine the correlation between wrist flexor power and grip strength of the power grip. An independent t-test was used to determine the significance level of the grip strength in the two-finger grip and four-finger grip. The significance level was set at p<.05 for all statistical tests. There was no interaction between the wrist flexor power and grip strength according to grip type (two-finger pinch grip, four-finger pinch grip, and power grip), but there was a significant difference in grip strength between the two-finger grip and four-finger grip (p<.05). The grip method that is necessary for grip strength when performing work may help to prevent musculoskeletal disorders.
