Biomechanically Based Shoulder Rehabilitation Strategies

The long-term objective of this research is to develop and test the effectiveness of biomechanically based rehabilitation strategies for improving upper extremity function and reducing pain and disability in persons with shoulder pathologies related to abnormal shoulder movement patterns. The project has two main goals. In the first, the researchers are collecting full-shoulder complex kinematics during arm elevation from healthy and symptomatic patients, which will be used in a state-of-the-art shoulder model to describe the three-dimensional function of the muscles to compare the different muscles and their relative abilities to contribute to or reduce kinematic deviations. The second goal is to use imaging data in combination with the kinematic data to animate the imaging data for highly accurate human movement descriptions. These data in combination will also help the researchers determine the effects of abnormal kinematics on the available volume of the subacromial space, providing insight into how specific kinematic deviations create impingement of soft tissue structures. The researchers use software available through MSI to model and visualize the three-dimensional bone structures and available volume. Results to date indicate a Hawkins/Kennedy Impingement test is more effective in reducing subacromial volume as compared to a Neer Impingement Test.
