Theses, Dissertations and Capstones
Introduction: The medial elbow is supported from valgus loading with the ulnar collateral ligament (UCL), the flexor pronator mass (FPM), and the radial head. Fatigue of muscle can lead to a decrease in force production. The decrease in force production can lead to a decrease in joint stability. This study tested the effect of fatigue of the FPM muscles on the width of the medial joint space.
Methods: Thirty-one participants volunteered for this study (18 female and 12 male, 1 excluded; mean height 170.2±10.1 cm, mean weight 71.2±15.6 kg, mean age 21.53±1.87 years old). Ultrasound images of the width of …

Background: The leading source of general population shoulder pain is subacromial impingement syndrome (SAIS) which can contribute to rotator cuff disease (RCD). 1 It has been reported that up to 12% of musicians end their musical career due to musculoskeletal injury.2 SAIS is a common source of shoulder pain in the bowing arm of upper string musicians.3 However, the mechanisms leading to shoulder pain in upper string musicians are not well known.
Purpose: The purpose of this study was to characterize aspects of the subacromial space anatomy while in standard playing positions of upper string musicians, specifically measurements …
