Markerless Radiostereogammetry Of The Shoulder Joint In Humans: Comparisons Of Scapulohumeral Kinematics Between Individuals With Healthy And Supraspinatus-Impaired Shoulders, Ashley N. Hannon
Electronic Thesis and Dissertation Repository
The purpose of this collection of studies was to further develop the knowledge of shoulder motion in order to better understand joint function through direct measurement of 3D scapulohumeral joint kinematics using a technique of high accuracy. Markerless, bi-planar fluoroscopic radiostereometric analysis using a generic shoulder model was developed in this thesis, reducing the amount of radiation exposure to subjects. The studies compared kinematic data of the scapulohumeral joint in six degrees of freedom with a precise, in-vivo measuring technique. Data were collected on young and older healthy individuals, individuals with a torn supraspinatus and post-surgical intervention.
Although this generic …

Theses, Dissertations and Capstones
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 …
