Different Levels of Blood Flow Restriction Versus Moderate Intensity Exercises in Patients with Knee Osteoarthritis

"Blood Flow Restriction (BFR) therapy involves units use standardized cuffs of varying widths and lengths which are physically attached to the devices and provide the capability of precisely controlling the amount of pressure applied to each limb during exercise or at rest.~We will be using Smart Cuffs® 4.0 which allows for a fast, hassle-free personalized pressure calculation. With the built-in pressure sensor and on-board computer, it will calculate and set the optimal pressure for each participant's limb. There is no need for an external doppler probe or hand pump. Made in the USA, SmartCuffs® are registered with the FDA as a Class 1 Medical Device.~Blood flow restriction therapy is commonly paired with resistive training, so this study will explore the effect of blood flow restriction at rest for patients with osteoarthritis at different restriction levels (50% for first group and 70% for second group)."

Patients assigned to group will receive strengthening of the lower limb musculature through moderate intensity resistance training (60% of 1RM) using a 45° leg-press machine, 90°-0° of knee flexion knee extension machine, leg curl machine and calf raise machine.
