Brief Summary:
This purpose of this study is to determine the outcomes of the first-known application of robotic therapy in the rehabilitation following rotator cuff repair, using a novel vertical oblique robotic module.

Condition or disease Intervention/treatment Phase
Rotator Cuff Tear Device: Robotic Therapy Not Applicable

Detailed Description:

Musculoskeletal conditions are a leading cause of disability in the United States accounting for more than 130 million patient visits to healthcare providers annually. Rotator cuff tears are one of the most common causes of pain and disability of the upper extremity. Impaired motor control of the shoulder girdle muscles with concomitant instability often exists prior to any surgical procedure. Re-tears and/or attenuation after rotator cuff repairs occur relatively frequently and may compromise the functional result. Loading of the UE during rehabilitation, thus the repair site, following the surgical procedure has been implicated in these complications Conventional shoulder rehabilitation protocols with the human-human interface do not possess the ability to systematically quantify dosing and progression for patients in the subacute stages thus, potentially overloading the repair site. No evidence-based research exists comparing outcomes of specific rehabilitative training protocols in these post-surgical patients. Consensus statements conclude, �a need for clinical trials, and validated outcome measures is essential�.

Advances in robotics technology offer unprecedented opportunities to improve rehabilitation pathways, but until now these technologies have focused primarily on neurological disease. The MIT Newman Laboratory for Biomechanics and Human Rehabilitation upper extremity (UE) robot is an impedance controlled, back-drivable, oblique-vertical vertical robot that has been designed such that it can safely exert controlled, graded forces to move or guide a limb, functioning in passive, active-assistive, active and resistive modes, providing objective data on the motion. A major advantage is its capacity for real-time, graded changes based on patient input, providing stability against random perturbations, increasing or withdrawing assistance and allowing for dose-specific treatment. The vertical robot device has been shown to be safe and well tolerated without any adverse effects such as shoulder pain.

Goal-directed, quantifiable rehabilitation protocols for redevelopment of function through improved range of motion, strength and motor control are lacking in patients with musculoskeletal impairments. The successful robotic-assisted rehabilitation of the acute and chronic, severe impairment provides an impetus for applying this technology to UE musculoskeletal impairments. The ability to objectively control and measure the dosing and progression during the rehabilitation process is a valuable tool in the advancement of evidence�based rehabilitation interventions The proposed pilot clinical trial will determine if 8-weeks of robotic rehabilitation improves the rate and quality of recovery of range of motion, strength, and function following rotator cuff repair compared with a conventional physical therapy rehabilitation protocol.
