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.

Abstract Context: The deceleration phase of the throwing motion creates large distraction forces at the shoulder, which may result in posterior shoulder tightness and ensuing alterations in shoulder range of motion (ROM) and may result in an increased risk of shoulder injury. Researchers have hypothesized that various stretching options increase this motion, but few data on the effectiveness of treating such tightness are available. Objective: To evaluate the acute effects of “sleeper stretches” on shoulder ROM. Design: Descriptive with repeated measures. Setting: Biomechanics laboratory and 2 separate collegiate athletic training facilities. Patients or Other Participants: Thirty-three National Collegiate Athletic Association Division I baseball players (15 pitchers, 18 position players; age  =  19.8 ± 1.3 years, height  =  184.7 ± 6.4 cm, mass  =  84.8 ± 7.7 kg) and 33 physically active male college students (age  =  20.1 ± 0.6 years, height  =  179.6 ± 6.6 cm, mass  =  83.4 ± 11.3 kg) who reported no recent participation (within 5 years) in overhead athletic activities. Intervention(s): Range-of-motion measurements of the dominant shoulder were assessed before and after completion of 3 sets of 30-second passive sleeper stretches among the baseball players. The ROM measurements in the nonthrower group were taken using identical methods as those in the baseball group, but this group did not perform any stretch or movement between measurements. Main Outcome Measure(s): Internal and external glenohumeral rotation ROM and posterior shoulder motion (glenohumeral horizontal adduction). Results: In the baseball group, posterior shoulder tightness, internal rotation ROM, and external rotation ROM were −3.5° ± 7.7°, 43.8° ± 9.5°, and 118.6° ± 10.9°, respectively, before the stretches and were −1.2° ± 8.8°, 46.9° ± 9.8°, and 119.2° ± 11.0°, respectively, after the stretches. These data revealed increases in posterior shoulder motion (P  =  .01, effect size  =  0.30) and in internal shoulder rotation (P  =  .003, effect size  =  0.32) after application of the stretches. No other differences were observed in the baseball group, and no differences were noted in the nonthrower group. Conclusions: Based on our results, the sleeper stretches produced a statistically significant acute increase in posterior shoulder flexibility. However, this change in motion may not be clinically significant.
