Opposite SI Joint Stretching for GIRD

Sacroiliac Stretching Improves Glenohumeral Internal Rotational Deficit of the Opposite Shoulder in Baseball Players in a Randomized Control Study

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.

Study Overview

• Status: Completed
• Conditions: Shoulder Impingement
• Intervention / Treatment: Procedure: Sleeper Stretch; Procedure: Opposite SI joint Stretch

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Sleeper stretch group; A certified athletic trainer supervised and observed the athlete as he performed the sleeper stretch on his dominant shoulder.	Procedure: Sleeper Stretch; Internal Range of motion of dominant shoulder
Experimental: Opposite SI joint Stretch; A certified athletic trainer supervised and observed the athlete as he performed the SI joint stretch opposite his dominant shoulder.	Procedure: Opposite SI joint Stretch; Internal range of motion of dominant shoulder
