| Research Abstract |
A prospective cohort study was conducted to determine the kinematic risk factor(s) of impingement syndrome that frequently occurs among athletes who participate in over-head sports. The results indicates that 15 out of 63 baseball pitchers and 21 out of 23 free-style swimmers use shoulder motions indicative of subacromial impingement. None of the participants used shoulder motions indicative of internal impingement. Twenty eight baseball pitchers participated in the cohort study over the period of three years and six participants used consistently the shoulder motions indicative of subacromial impingement during the performance. Of the six, four participants later developed severe shoulder pain, being placed on the disabled list for a while.
