Effect of Adding Blood Flow Restriction to Strengthening Exercise in Patients With Patellofemoral Pain Syndrome

"Blood flow restriction training is an accessory to a variety of different exercise modes (e.g., resistance exercise, walking, cycling) has recently become a popular research topic. It involves the application of pressurized cuffs to the proximal portion of each lower extremity or upper extremity. It enhance blood pooling in the capillary beds of the limb muscles distal to the tourniquet or cuff.~The 3rd Generation SmartCuffs® pump (SmartCuffs® 3.0 PRO) is Personalized Pressure feature which allows for a fast, hassle-free personalized pressure calculation. With the built-in pressure sensor and on-board computer, it is calculate arterial occlusion pressure and set the optimal pressure for patient's body. There is no need for an external doppler probe or hand pump. This unit will do everything for patient. Smart Cuffs 3rd generation is FDA Approved Listed Class 1 device.~The automatized tourniquet (Smart Tools) contains a ring-shaped single- chamber"
