Guided Grip Force of the Dominant hand for Male Subjects
Subjective rating has been adopted in quantifying the physical exertion in industrial works. In this study, an experiment was conducted to measure the grip force of twenty male subjects tinder gnidedgripping scenario. The snbjects were requested to apply a power grip force with one of the four exertion levels toward their maximum voluntary contraction (MVC) using their dominant hands. The analysis of variance was conducted to test the variations of the grip forces among different level of force exertion. The results were statistically significant (p<0.0001). A linear regression model was established to describe the relationship between the gripping force and the perceived hand exertion based on the Borgs CR-10 scale. This model was statistically significant at P<0.0001 and with an R2 of 0.9. The Pearsons correlation coefficient between the grip force and the rating of the CR-10 scale was 0.95. The results of this study showed that the guided grip force of the dominant hand of the male subjects had linear relationship with the ratings of CR-10 scale. Therefore, the CR-10 scale is appropriate as a quantitative measure of perceived hand grip exertion of the dominant hand for males.
