Methods: From January 2015 to January 2016, 107 patients suffering from shoulder pain underwent both US and MRI of the shoulder at a medical center to identify their shoulder pathology, and were included in this work. The US was performed by a physiatrist at a US laboratory, and the US findings for the SS tendon were classified as normal, tendinosis (calcific/ non-calcific), a partial-thickness tear, or …

The Role Of Scapular Morphology In Reverse Shoulder Arthroplasty, Ashish Gupta

Electronic Thesis and Dissertation Repository

Baseplate fixation in a reverse shoulder arthroplasty depends on adequate bone stock. In cases of severe glenoid bone loss and revision shoulder arthroplasty, deficiency of the glenoid vault compels the surgeon to attain screw fixation in the three columns of the scapula. The relationship of these columns demonstrated that the coracoid is closer to the lateral scapular pillar in females than in males. Significant gender dimorphism exists between the orientations of the three columns. The gender dimorphism is further evaluated by anthropometric measurements of the scapular body and the glenoid. The clinical significance lies in the ability to reconstruct the …

Methods: Nine healthy competitive college tennis players from a Division III college participated in this study. High speed motion capture allowed for 3-D analysis of shoulder kinematics during a tennis serve. Two conditions were evaluated while the athletes performed a high velocity tennis serve: standard tennis shirt and a …

Wearable Imu For Shoulder Injury Prevention In Overhead Sports, Samir A. Rawashdeh, Derek A. Rafeldt, Timothy L. Uhl

Physical Therapy Faculty Publications

Body-worn inertial sensors have enabled motion capture outside of the laboratory setting. In this work, an inertial measurement unit was attached to the upper arm to track and discriminate between shoulder motion gestures in order to help prevent shoulder over-use injuries in athletics through real-time preventative feedback. We present a detection and classification approach that can be used to count the number of times certain motion gestures occur. The application presented involves tracking baseball throws and volleyball serves, which are common overhead movements that can lead to shoulder and elbow overuse injuries. Eleven subjects are recruited to collect training, testing, …

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 …

Assessment Of Shoulder Active Range Of Motion In Prone Versus Supine: A Reliability And Concurrent Validity Study, James Furness, Scott Johnstone, Wayne Hing, Allan D. Abbott, Michael Climstein

Allan D. Abbott

BACKGROUND: As swimming and surfing are prone dominant sports, it would be more sport specific to assess shoulder active range of motion in this position. OBJECTIVES: To determine the reliability of the inclinometer and HALO© for assessing shoulder active range of motion in supine and prone and the concurrent validity of the HALO©. Concurrent validity is based on the comparison of the HALO© and inclinometer. To determine if active range of motion (AROM) differences exists between prone and supine when assessing shoulder internal (IR) and external rotation (ER). DESIGN: The design included clinical measurement, reliability and validity. METHODS: Thirty shoulders …

A Rigid Body Model For The Assessment Of Glenohumeral Joint Mechanics: Influence Of Osseous Defects On Range Of Motion And Dislocation, Mark F. Welsh, Ryan T. Willing, Joshua W. Giles, George S. Athwal, James A. Johnson

Bone and Joint Institute

© 2016. The purpose of this study was to employ subject-specific computer models to evaluate the interaction of glenohumeral range-of-motion and Hill-Sachs humeral head bone defect size on engagement and shoulder dislocation. We hypothesized that the rate of engagement would increase as defect size increased, and that greater shoulder ROM would engage smaller defects. Three dimensional computer models of 12 shoulders were created. For each shoulder, additional models were created with simulated Hill-Sachs defects of varying severities (XS=15%, S=22.5%, M=30%, L=37.5%, XL=45% and XXL=52.5% of the humeral head diameter, respectively). Rotational motion simulations without translation were conducted. The simulations ended …

The Painful Long Head Of The Biceps Brachii: Nonoperative Treatment Approaches, Kevin E. Wilk, Todd R. Hooks

Physical Therapy Faculty Research and Publications

Pain associated with the long head of the biceps (LHB) brachii seems to be increasingly recognized in the past 4 to 5 years. The LHB has long been considered a troublesome pain generator in the shoulder. Abnormality involving the LHB brachii has long been an area of debate, with Codman in 1934 even questioning the specificity of the diagnosis of biceps tendinitis. Biceps tendon abnormality is often associated with rotator cuff impingement. Shoulder pain originating from the biceps tendon can be debilitating, causing a severe decrease in shoulder function. As a result of the frequent clinical presentation of biceps pain, …
