Electromyography Evaluation of Subscapularis Function After Total Shoulder Arthroplasty

NCT00779974 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 32

Last updated 2023-11-03

No results posted yet for this study

Summary

The primary objective is to document function of the structurally intact subscapularis after total shoulder arthroplasty by using electromyography. Structural integrity of the subscapularis will be confirmed using ultrasound.

The secondary objective is to determine the diagnostic accuracy of the belly compression and lift off tests in evaluating the integrity and function of the subscapularis when compared to the ultrasound and electromyography (EMG).

This will be accomplished by enrolling and evaluating patients with a primary diagnosis of osteoarthritis who have had a total shoulder replacement preformed by the PI from September 2003 through December 2007.

Evaluation

For this research study each enrolled subject will have a clinical exam, including range of motion (ROM), and strength testing. The lift off and belly compression tests will be performed. An ultrasound of the shoulder will be done to determine the integrity of the subscapularis tendon. An EMG will be done to determine functionality of the subscapularis.
