Blood Flow Restriction Therapy in Lower Limb Extensor Injuries: A Randomized Controlled Double-Blind Study
NYU Langone Health
Summary
The primary objective of the study is to determine the efficacy of blood flow restriction therapy on patients with lower limb extensor injuries by measuring pre and post blood flow restriction therapy strength and muscle mass.
Description
The purpose is to restrict venous outflow with an inflatable cuff to create a high intensity environment increases muscle hypertrophy, thus promoting a more efficient form of rehabilitation. Blood flow restriction therapy is a blood pressure cuff placed around the desired limb with a handheld device that controls the pressure exerted by the cuff. The cuff is placed around the desired limb before a specific exercise, the physical therapist determines the appropriate pressure and time, and the patient completes the exercise as they normally would. The monitor determines the limb occlusion pressu…

Inclusion Criteria: * Must be at least 18 years of age and younger than 65 years of age * ASA class I-II * Diagnosed with a lower limb extensor injury (quadriceps tendon rupture, patella tendon rupture, patella fracture) * Intention to receive physical therapy as standard of care Exclusion Criteria: * Legally incompetent or mentally impaired (e.g. minors, Alzheimer's subjects, dementia, etc.) * Younger than 18 years of age or older than 65 * Any patient considered a vulnerable subject * Patients with impaired circulation, peripheral vascular compromise, previous revascularization of the ext…
Interventions
- BehavioralPhysical Therapy with pressure cuff
6 weeks of physical therapy will have similar exercises to standard therapy however the patients will use a cuff around the affected leg during the exercises.
- BehavioralPhysical Therapy with placebo pressure cuff
6 weeks of physical therapy will have similar exercises to standard therapy however the patients will use a pressure cuff around the affected leg during the exercises. The pressure cuff will have 50% of the pressure that will be considered effective.
