An Electromyographic Study Of Lower Trapezius Muscle Activity During Exercise In Traditional And Modified Positions, Erika Engelstad
Physical Therapy Scholarly Projects
Shoulder rehabilitation commonly overlooks the influence of scapular muscles in providing the stability necessary for the shoulder to function properly. When considering muscles acting on the scapulothoracic articulation, literature suggests that the lower trapezius is a key stabilizer of this articulation. Traditionally, the lower trapezius is exercised while the patient is in a prone position with the humerus abducted 1450 while performing forward elevation. Unfortunately, repeated overhead activity has been proven to increase the incidence of shoulder impingement. In an effort to avoid exercising the lower trapezius in a position that would compromise the shoulder complex, a modified position of …

An Electromyographic Study Of The Shoulder Musculature During Codman's Exercises, Myndi L. Frey
Physical Therapy Scholarly Projects
Codman's exercises are commonly used in physical therapy as a supposed passive shoulder activity to help increase range of motion without causing detrimental damage to the injured tissue or surgical graft. These mild shoulder exercises are often the first exercises used post- operatively. Some clinicians often add a weight to the hand or wrist with the assumption that the distraction will decrease the impingement between the acromion and the shoulder musculature while performing these exercises. The purpose of this study is to determine the level of muscle activity within the shoulder musculature during Codman's exercises with and without the addition …
