Official title
Restoration of Glenohumeral Internal Rotation Deficit (GIRD) After Throwing: A Randomized Clinical Trail Comparing the Sleeper Stretch to the 90/90 Hip Lift With Balloon Blow Exercise
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary purpose of this study is to determine if the loss of internal rotation following a throwing session is best restored through soft tissue stretching with the sleeper stretch or with scapular repositioning with the 90/90 hip lift with balloon blow exercise. This study will progress the body of research related to internal rotation deficits with regards to baseball throwers. The research will be relevant to clinicians who treat patients with baseball players with internal rotation loss. High school baseball players will be the targeted subjects for this study. They will perform two exercises (one per week) designed to increase shoulder internal rotation over the course of three weeks with one week of rest between intervention weeks. The primary outcome will be shoulder internal rotation range of motion improvements over the course of one week's time. There are no known adverse risks to either intervention.
