Abstract
Thirty-one male subjects were tested in accordance with the three phases of this study to investigate their performance on the side arm positional test of kinesthesis. In phase I, five subjects were tested at 13 test angles on two different days. Twenty-one subjects were tested two different days on six test angles in phase II. In phase III, five subjects were tested at two test angles over a 10-day period. The findings in this study would appear to warrant the conclusions that (a) the side arm positional test was found reliable from day to day, (b) statistically significant differences in test performance were found between arms with the nondominant arm deviating less from the specific tested angle, (c) accuracy of test performance tended to improve as the size of the specific test angle increased, and (d) in most instances, test performance was more exact following practice over a 10-day period.
