Purpose: Recently ultrasound images has been used to measure the subacromial space with a linear measurement of the acromiohumeral distance. The purpose of this study was to comparison of distance of subacromial space using ultrasonographic measurement on arm positions of shoulder injured patients.
Methods: The subjects were 30 shoulder injured patients (19 males and 11 females). Ultrasonography was performed to measure subacromial space during each shoulder resting position, abduction, internal rotation with abduction and external rotation with abduction.
Results: Subacromial space was a significantly difference between injured arm and normal arm at shoulder resting position. At abduction, subacromial space was narrowing significantly between injured arm and normal arm. At external rotation with abduction, subacromial space were wider in normal arm than in injured arm but it was not significantly. Intra-observer reliability for ultrasonography measurement of subacromial distance was excellent (.96~.99).
Conclusion: These results identified that positions of injured shoulder was related to subacromion space.
