The purpose of this study was to determine whether a one-week period of immobilization resulted in a significant decrease in the grip strength and/or pinch strength of normal subjects.; The participants in this investigation were right-handed females between the ages of 21 and 45. Throughout the one-week period between the pre-test and post-test, each subject assigned to the experimental group had her left hand immobilized in a cast. During the pre-test and post-test, all of the subjects had their left hands tested for grip strength and pinch strength. A separate unpaired t-test was then calculated for grip strength measured with the handle of the hand dynamometer in each of the five positions as well as for the strength of the three-jaw chuck, tip prehension, and lateral prehension.; After analyzing the data, it was concluded that a one-week immobilization period did not significantly affect the strength of grip or pinch.
