Acromio-Humeral Distance Variation Measured by Ultrasonography and Its Association With the Outcome of Rehabilitation for Shoulder Impingement Syndrome

Abstract

The ultrasound measure of AHD is reliable and sensitive. Although a distinct pattern of AHD variation in SIS patients could not be confirmed, a strong positive relationship was found between the reduction of AHD narrowing and functional improvement following rehabilitation. Ultrasound measurement of AHD might help identify SIS patients who will benefit from rehabilitation.
