Blood Flow Restriction Training in Rehabilitation Patients

Stopped early · Not applicable

Conditions studied: Anterior Cruciate Ligament Reconstruction, Volumetric Muscle Loss, Chronic Thigh Muscle Weakness, Knee Arthroscopy

In brief

Occlusion training, resistance exercise performed with a specialized venous tourniquet, leads to beneficial changes in muscle at low resistance and minimal stress on the nearby joint. This novel resistance training has the potential to greatly improve extremity muscle strength gains for rehabilitation patients who are unable for medical reasons to perform high resistance exercise. Our study will explore this with specific rehabilitation populations: post-operative knee scopes, post-operative anterior cruciate ligament (ACL) reconstruction patients who have acute post-operative changes in thigh muscle function and chronic thigh weakness. The primary outcome is to achieve accelerated functional thigh recovery with outcome measures including thigh strength, validated questionnaires, and validated functional testing. Occlusion training can enhance rehab patients outcomes, reduce the cost of care, and improve the skills and efficiency of care providers.
