Abstract
BACKGROUND: Shoulder impingement syndrome (SIS) is the most common disorder of the shoulder, resulting in functional loss and disability The etiology of SIS is multifactorial. Postural, kinematic, and muscle changes have all been demonstrated to directly or indirectly alter the subacromial space dimension. OBJECTIVE: The purpose of this study was to investigate if there is any relationship between core stability measures and the closed chain shoulder function in athletes with shoulder impingement syndrome. METHODS: Forty three patients had participated in this study. With age ranged for twenty to thirty five years. Each patient was assessed for trunk extension, trunk flexion hold times, transversus abdominis activation ratio by ultra sound and Transversus abdominis activation capacity by the pressure biofeedback unit in addition to the upper quarter Y balance test RESULTS: The results showed non-significant association between (the maximum holding times for trunk flexor endurance, transversus abdominis activation ratio measured by ultrasound and transversus abdominis activation capacity measured by the pressure biofeedback unit) and upper quarter Y balance test scores but there was fair positive association between the maximum holding time for trunk extensors endurance and the upper quarter Y balance test scores in athletes with shoulder impingement syndrome
