This study examines the effects of short-term immobilization of the nondominant upper limb on proprioceptive acuity. Subjects will complete upper limb matching tasks with varying degrees of difficulty in order to examine the effects of immobilization on elbow joint position awareness. Absolute error, defined as the absolute value of the difference between the final target and matching positions, will be the primary measure of overall endpoint matching performance used in this study. It is hypothesized that immobilization of the nondominant elbow joint will result in a transient decrease in proprioceptive ability.
