Random allocation software will be used to create random sequences. The central randomization method will also be used to hide the allocation concealment, Blinding description: The subjects will be randomly assigned to one of the three study groups . The subjects will not be aware of the type of intervention of other groups. N/A Patellofemoral Pain Syndrome. Intervention 1: Intervention group: The exercises include hip external rotation while lying on the side, hip external rotation while sitting on the table, step down, knee extension between 0 and 30 degrees, and isometric contraction with a ball(subjects hold a ball between their knee), they perform all exercises with 30% of 1RM. This training performed 6 weeks and 3 sessions per week (1 hour per session). Intervention 2: Control group: The traditional exercises include hip strengthening exercises and quadriceps strengthening exercises. The intensity of their exercise is in a comfortable and painless condition. This training performed 6 weeks and 3 sessions per week (1 hour per session). Intervention 3: Intervention group: The training programs with blood flow restriction (BFR) as described before were used in conjunction with blood flow occlusion during exercises. The Katsu device was used for blood flow occlusion. Arterial occlusion pressure was measured by placing a pneumatic cuff on the proximal thigh in a standing position. The cuff pressure was set to 120 mmHg at the beginning of the exercises (this pressure was chosen based on previous research results and the capability of the present study's participants, and the training load was adjusted accordingly). The cuff was removed 30 seconds after the last set of each exercise and reapplied before the first set of the next exercise. Note: Approximately 10% of the participants reported a pain level of 7 or 8. For these individuals, the training pressure was reduced according to the physician's advice, and the exercises were performed with lower pressure. Additionally, since all exercises were performed in the last 30 degrees of knee extension, the reaction force between the patella and femur was minimized, resulting in significantly less pain compared to daily activities. This training performed 6 weeks and 3 sessions per week (1 hour per session). Yes - There is a plan to make this available What will be shared: After Completion of Interventions And Final Evaluation, The Data Will Be Shared Through The Articles To Provide a Comprehensive Treatment Process. When: The Results of This Study Will Be Available In Journals 6 Months After Publication To whom: The Results of The Studies Will Be Accessible to All Individuals in The Community Without Any Restrictions Conditions: The Documentation Provided Can Be Applicable to Many Musculoskeletal Pain Syndromes as a Comprehensive Treatment Intervention That Considers Several Factors. These Interventions Are Applicable If Prescribed And Monitored By Physicists .

Timepoint: The primary outcome measurement time points will be conducted before the intervention and 8 weeks after the intervention. Method of measurement: Pain will be assessed using the Visual Analog Scale (VAS). Balance, Proprioception, Strength, and Knee kinematics. Timepoint: The secondary outcome measurement time points will be conducted before the intervention and 8 weeks after the intervention. Method of measurement: For assessment, the Y Balance Test will be used for dynamic balance, the Stork Test for static balance, a goniometer for proprioception, automated video analysis for dynamic systems to assess kinematics, and a handheld dynamometer for muscle strength. faculty of Sport Sciences, Islamic Azad University,Khorasgan Branch, Isfahan, Iran Approved 2022-11-06 Ethics Committee of Islamic Azad University, Isfahan (Khorasgan) Branch Faculty oof Nursing, Arghavanieh, Jey St, Isfahan, Iran Isfahan Isfehan Iran (Islamic Republic of)
