pain, knee extensor strength
SAID
In this randomized controlled clinical trial of patients with PFP, home-based exercise provided superior clinical outcomes to control after six weeks of follow-up. Moreover, higher knee extensor strength was observed in the intervention group than in the control group after the intervention. Therefore, we recommend home-based exercise as the basis of treatment for patients with PFP.Exercise therapy is important, commonly used in clinical practice, and recommended by the guidelines from the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association [That being said, most previous studies have focused on a supervised exercise program, and there is a lack of evidence for the effectiveness of patient self-management through exercise for PFP. One previous study found that an online exercise program without guidance from a physiotherapist is beneficial for improving pain complaints and neuromuscular performance in PFP patients [Reducing pain and improving function are the main goals of PFP rehabilitation. A previous study demonstrated that an eight-week home physical therapy program had a significant effect on pain relief and function improvement [Quadriceps muscle strength, which is associated with the PFP [
