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

Overview

To study the effect of adding BFRT to strengthening exercises and compare it with strengthening exercises alone in improving, muscular strength, pain, function, joint position sense, and dynamic balance test (star excursion test). in patients with PFPS.

Background: Patellofemoral Pain Syndrome (PFPS) is a common condition characterized by anterior knee pain, particularly affecting individuals aged 15-30. It often involves lower limb muscle weakness, particularly in the quadriceps, which can exacerbate symptoms and affect functional performance. Blood Flow Restriction Training (BFRT) has shown promise in enhancing muscle strength and functional outcomes with reduced intensity compared to traditional high-intensity training. Purpose: This study aims to compare the efficacy of combining BFRT with traditional strengthening exercises versus using strengthening exercises alone in improving muscular strength, pain, function, joint position sense, and dynamic balance in patients with PFPS. Methods: A triple-blinded, randomized controlled trial was conducted at the Almenshawy General Hospital, Tanta, Egypt. Fifty patients with unilateral non-traumatic PFPS, aged 18-35, were randomly assigned to either a strengthening exercises group (SE Group) or a BFRT plus strengthening exercises group (BFRT Group). Both groups underwent a 6-week intervention with three sessions per week. Outcomes assessed included quadriceps and hip abductors strength, pain severity (Visual Analog Scale), functional status (Kujala Patellofemoral Score), joint position sense (measured by digital inclinometer), and dynamic balance (Star Excursion Balance Test).
