Intervention model: SINGLE_GROUP
Intervention model description: All 23 players of a minor league baseball team voluntarily participated in the study.
Primary purpose: TREATMENT

Brief summary: The purpose of this study is to investigate if stretching the contralateral sacroiliac (SI) joint improves GIRD in baseball players. Additionally, we aimed to compare our SI joint stretching regiment with a classically described sleeper stretch routine.

Detailed description: Abstract:

Background:

Glenohumeral Internal Rotational Deficit (GIRD) is a well-documented finding in throwing athletes.

Hypothesis/Purpose:

The purpose of this study is to investigate if stretching the contralateral sacroiliac (SI) joint improves GIRD in baseball players. Additionally, the effect of the SI joint stretch will be compared to that of the classically described sleeper stretch.

Study Design:

Randomized Controlled Clinical Trial

Methods:

With the athlete supine and arm abducted 90o, internal rotation of both shoulders was measured in 23 minor league baseball players.

Next, each player randomly was assigned to either a control (sleeper stretch of dominant shoulder) or experimental (stretch of the SI joint contralateral to the dominant shoulder) group supervised by a certified athletic trainer. The players performed their own stretches.

Finally, the initial two investigators, unaware of to which group the player was assigned, re-measured the end-range internal rotation of each athlete's dominant shoulder.

Eligibility criteria: Inclusion Criteria:

* All members a minor league baseball team

Exclusion Criteria:

* Any active shoulder or back injury or history of shoulder or back injury

Primary outcomes:
measure: Shoulder internal ROM after stretching opposite SI joint
timeFrame: Measurement made within 30 minutes of stretching
Secondary outcomes:
measure: Shoulder Internal ROM after sleeper stretch
timeFrame: Measurement made with 30 minutes of stretching
