Throwing injuries.


To study the effects of posterior capsule tightness on humeral head position in late cocking simulation.


Eight fresh frozen shoulders were placed in position of “late cocking,” 90 degrees abduction, and 10 degrees adduction and maximal external rotation. 3D measurements of humeral head relationship to the glenoid were taken with an infrared motion sensor, both before and after suture plication of the posterior capsule. Plications of 20% posterior/inferior capsule and 20% entire posterior capsule were performed, followed by plications of 40% of the posterior/inferior capsule and 40% entire posterior capsule.


Cadaver Lab.


Posterior capsular placation.

Main Outcome Measures:

Humeral head position.


40%, but not 20%, posterior/inferior and posterior plications demonstrated a trend to increased posterior-superior humeral head translation relative to controls.


Surgically created posterior capsular tightness of the glenohumeral joint demonstrated a nonsignificant trend to increased posterior/superior humeral head translation in the late cocking position of throwing.

Context: Alterations in posture and motion patterns are thought to play a role in developing shoulder injuries in overhead athletes. Taping is widely used in the sporting population, but there are limited empirical data regarding its effectiveness. Objectives: To determine and compare the effects of rigid and kinesio taping on shoulder rotation motions, posterior shoulder tightness (PST), and posture in overhead athletes. Design: Randomized controlled trial. Setting: Athletic training rooms. Participants: Eighty-six asymptomatic elite overhead athletes. Interventions: Participants were randomly divided into 4 groups: rigid taping group (RTG) that underwent therapeutic rigid taping, kinesio taping group (KTG) that underwent therapeutic kinesio taping, placebo group that underwent placebo kinesio taping (shoulder and scapular region taping for taping groups), and control group (no taping). Main Outcome Measures: Shoulder rotation motions, PST, and head and shoulder posture were evaluated at baseline, immediately after application and 60 to 72 hours after application for all groups. Results: Glenohumeral internal rotation increased immediately (P < .001) and at 60 to 72 hours after application in the KTG (P = .01), whereas it decreased immediately after application in the RTG (P < .001). Immediately after application, total rotation range of motion increased in the KTG (P =.02) and decreased in the RTG (P < .001), and there was a difference between groups (P = .02). Immediately after application, PST increased in the RTG (P < .001); after 60 to 72 hours, it decreased in the KTG (P = .04) and increased in the RTG (P = .01). Posture outcomes did not change significantly (P > .05). Conclusions: Kinesio taping may improve and rigid taping may worsen glenohumeral internal rotation and PST in overhead athletes. For increasing total rotation range of motion, kinesio taping is superior to rigid taping. Taping did not affect posture. Short-term kinesio taping in overhead athletes may be useful to improve glenohumeral internal rotation, total rotation range of motion, and PST.
