BACKGROUND Overhead sports place the greatest strain on the elbow of any of the upper extremity joints. Unfortunately, athlete-specific functional outcome tools do not exist for the elbow. HYPOTHESES THE ELBOW DEMAND RATING SCALE (EDS) WILL DEMONSTRATE STRONG RELIABILITY AND VALIDITY PROPERTIES: (1) test-retest reliability with a 2-week EDS administration, (2) internal reliability of the subs...
