THE RELIABILITY OF REHABILITATIVE ULTRASOUND IMAGING IN THE MEASUREMENT OF INFRASPINATUS MUSCLE FUNCTION IN THE SYMPTOMATIC AND ASYMPTOMATIC SHOULDERS OF PATIENTS WITH UNILATERAL SHOULDER IMPINGEMENT SYNDROME

摘要

Rehabilitative ultrasound Imaging (RUSI) is increasingly used in the management of musculoskeletal conditions as it provides an objective measure of muscle function while being less invasive than needle electromyography. While research has documented the ability to reliably measure trunk muscles in patients with back pain, no study to date has used RUSI to quantify infraspinatus muscle function in patients with shoulder impingement syndrome (SIS).
