The Acute Effects of Different Stretching Methods in Individuals With Subacromial Impingement Syndrome

Not Applicable

Completed

• Conditions: Glenohumeral Internal Rotation Deficit; Subacromial Impingement Syndrome
• Interventions: Other: Isolytic stretching group; Other: Control group; Other: Static stretching group

• Registration Number: NCT03246867
• Lead Sponsor: Dokuz Eylul University

Brief Summary

The purpose of this study is to investigate and compare the acute effects of isolytic and static stretching training in individuals having subacromial impingement syndrome with glenohumeral internal rotation deficit. Isolytic group will receive isolytic stretching in modified cross body position. Static group will receive static stretching in modified cross body position. Stretching groups will be evaluated before and just after stretching exercise. Control group will receive no stretching. Control group will be evaluated for the first time and then will be waited until the duration of the stretching exercise program. Afterwards, second evaluation will be performed

Detailed Description

There is no information in literature about the acute effects of isolytic stretching exercise in individuals having subacromial impingement syndrome with glenohumeral internal rotation deficit. The purpose of this study is to investigate and compare the acute effects of isolytic and static stretching training in individuals having subacromial impingement syndrome with glenohumeral internal rotation deficit.

In modified cross body position, static stretching group will perform active-assistive static stretching by the physiotherapist whereas isolytic stretching group will perform active-assistive isolytic stretching. Stretching exercises will be applied five times each for 15 seconds. After each stretching there will be a resting period for 5 seconds. Control group will receive no stretching. They will be handed a brochure about the stretching techniques and its role in injury prevention. Isolytic and static stretching groups will be evaluated before and just after stretching exercise. Control group will be evaluated for the first time and then will be passively waited until the duration of the stretching exercise program (approximately 4-5 min). Afterwards, second evaluation will be performed.
