INTRODUCTION/PURPOSE: Shoulder dysfunction and injury are common in throwing athletes. Loss of internal rotation has been correlated to shoulder pathologies. The purpose of this study was to assess the effects of a stretching protocol on passive internal rotation. The purpose of this study was assess the effects of a stretching protocol on passive internal rotation motion in the throwing shoulders of collegiate baseball players.
Pre-Post, intervention, using a within subjects comparison of a convenience sample.
Glenohumeral internal rotation and external rotation of the throwing and non-throwing shoulders of NCAA Division I baseball players were measured using a universal goniometer. Determinations were made as to the degree of Glenohumeral Internal Rotation Deficit (GIRD) in the throwing shoulder. A daily (5 days per week), 12-week posterior capsule stretching program was administered. Post-stretching internal rotation and external rotation measures were again obtained. The coaches and athletic trainers of the included team monitored the players for shoulder injuries and innings of training/competition lost due to shoulder injuries during the 12 week intervention.
A significant increase in range of motion was found for dominant arm internal rotation (IR) and total range of motion (TOT) following the stretching program. No statistically significant improvement in range of motion was found for external rotation (ER), non-throwing arm internal rotation (NDIR), non-throwing arm external rotation (NDER), and non-throwing arm total motion (NDTOT).
Implementation of a posterior capsule stretching program may be helpful to facilitate increased passive internal rotation range of motion at the glenohumeral joint. Further research should be performed using a control group not receiving the stretching program in order to more completely establish the impact of stretching on measures of passive glenohumeral range of motion.

引言/目的：肩部功能障碍和损伤在投掷运动员中很常见。内旋丧失与肩部病变相关。本研究的目的是评估一种拉伸方案对被动内旋的影响。本研究的目的是评估一种拉伸方案对大学棒球运动员投掷肩部被动内旋运动的影响。
前后对照、干预性研究，采用便利样本的受试者内比较。
使用通用测角仪测量美国大学体育协会（NCAA）一级棒球运动员投掷肩和非投掷肩的肱盂内旋和外旋。确定投掷肩的肱盂内旋不足（GIRD）程度。实施为期12周的每日（每周5天）后关节囊拉伸计划。再次获得拉伸后的内旋和外旋测量值。在为期12周的干预期间，所纳入球队的教练和运动训练师监测球员的肩部损伤情况以及因肩部损伤而损失的训练/比赛局数。
拉伸计划后，优势臂内旋（IR）和总活动范围（TOT）的活动范围显著增加。外旋（ER）、非投掷臂内旋（NDIR）、非投掷臂外旋（NDER）和非投掷臂总活动范围（NDTOT）的活动范围在统计学上没有显著改善。
实施后关节囊拉伸计划可能有助于增加肱盂关节的被动内旋活动范围。应使用未接受拉伸计划的对照组进行进一步研究，以便更全面地确定拉伸对肱盂被动活动范围测量的影响。
