  • Closed-chain Exercise for Patients with Rotator Cuff Tears  

       

    The purpose of this study is to determine the feasibility, acceptability, and patient-reported and performance outcomes of a 5-month closed-chain rehabilitation protocol for patients with full-thickness rotator cuff tears.Secondarily, the effects of the closed-chain rehabilitation protocol on, shoulder impairments, tendon morphology, and shoulder biomechanics will be assessed. These rehabilitation exercises, if demonstrated to be effective, could be used to direct treatment for future patients with rotator cuff tears. 

    This project is funded by Barbara Fried, Fried Companies, Inc. (2015-2018).

    Do you have a rotator cuff tear?
    We are inviting individuals between the ages of 40 and 85 who have a full-thickness rotator cuff or a failed rotator cuff repair and have not participated in physical therapy within the last 3 months.

    Reliability of Scapula Symtom Alteration Tests in Patients with Shoulder Pain  

    Laboratory studies have revealed abnormal scapular kinematics,reduced scapular muscle performance, and reduced shoulder flexibility in patients with shoulder pain as compared to asymptomatic shoulders. The Scapular Assistance and Scapular Reposition Tests are commonly used during clinical evaluation of patient with shoulder pain however the reliability of these tests has not been established. The purpose of this study is to (1) determine the reliability of the Scapular Assistance and Scapular Reposition Tests and (2) assess if the Scapular Assistance and Scapular Reposition Tests can identify patients who would benefit from scapular focused treatment.

    Assessment of Shoulder Function and Muscle Activation in Patients with Spinal Accessory Nerve Injury

    Shoulder dysfunction is prevalent in individuals with spinal accessory nerve injury. Spinal accessory nerve injury affects the muscle activity and function of the lower trapezius muscle.Weakness or paralysis of the trapezius muscle may cause a loss in shoulder and scapula motor control. However biomechanical factors such as tendon characteristics, shoulder mechanics and muscle activation during arm elevation are not well understood. The purpose of this study is to investigate shoulder function and muscle activity in patients with spinal accessory nerve injury.

    Health Services and Cost Comparison of Clinical Pathways for Shoulder Disorder: Treatment Dosing and Treatment Delivery

     

    Manual therapy (MT) is in the scope of practice of multiplehealthcare providers, and can be an effective intervention forshoulder disorders. However, it is not clear as how much MT (dose)should be used, and if it should be combined with exercise(delivery). Prior research on MT as a treatment for shoulder painhas focused on patient-rated outcomes. Our overall goal is todetermine the impact of MT characteristics on downstreamutilization of healthcare services and costs. Specifically, theaims of the project are to characterize the influence of MT dosingand MT delivery (alone or combined with exercise) on downstreamutilization of healthcare services and costs in the 12 months afteran initial visit for a shoulder condition.

    Shoulder Pain: Effects of Adherence to Practice Guide Lines and Dose of Physical Therapy on Outcomes of Care. SPEADO Project

     

    Clinical Practice Guidelines (CPGs), such as those developed by the Orthopaedic Section, were written to enable clinical decision-making. Shoulder pain is a common complaint, and rotatorcuff (RC) disease is the most prevalent shoulder diagnosis.Recently, evidence-based CPGs have been published for RC disease,but to guide clinicians in the treatment of RC disease. While these CPGs are evidence-based, there is a lack of evidence as to the effects of adherence to the CPGs on patient-rated outcomes, and the relationship to dose of care. This project will convert clinical data into meaningful data elements to define CPG adherence for RC disease, and define the relationships to patient outcomes and dose of care.

      • Mechanisms and Effects of Thoracic Spine Manipulation in Patients with Shoulder Pain 

    The aim of this project is to examine biomechanical and neurophysiological mechanisms of thoracic spinal manual therapy in patients with rotator cuff disease, and to determine the effects on immediate outcomes of shoulder pain and function in patients with rotator cuff disease.

     • Effectivenessof Rehabilitation for Subacromial Impingement Syndrome

    This is a multi-center clinical trial designed to examine the short-term and long-term outcomes of treatment for patients with subacromial impingement syndrome, and to develop a clinical predication rules for those patients who respond and for those who do not respond to a conservative 6-week rehabilitation program consisting of manual therapy to the upper quadrant, therapeutic exercise, posture, and a home exercise program of a prescribed progression and patient education.
