Biomechanics of the knee during closed kinetic chain and open kinetic chain exercises.
PURPOSE Although closed (CKCE) and open (OKCE) kinetic chain exercises are used in athletic training and clinical environments, few studies compared knee joint biomechanics while these exercises are performed dynamically. Expand

Osseous Adaptation and Range of Motion at the Glenohumeral Joint in Professional Baseball Pitchers *
The throwing shoulder in pitchers frequently exhibits a paradox of glenohumeral joint motion, in which excessive external rotation is present at the expense of decreased internal rotation. The objectExpand

Operative Treatment of Ulnar Collateral Ligament Injuries of the Elbow in Athletes
Over a 6-year period, the senior author (JRA) performed 91 ulnar collateral ligament reconstructions (N 78) or repairs (N 13). All patients were male and between the ages of 15 and 39 years (average,Expand
