Evaluate the effect of High-Intensity Focused Electromagnetic Therapy on pain, quadriceps strength, and quality of life in patients with patellofemoral pain syndrome
Patients diagnosed with patellofemoral pain syndrome will be recruited from outpatient physical therapy clinics. Following a comprehensive clinical screening, eligible participants will be randomly assigned into two parallel groups: The Study Group: Will receive true High-Intensity Focused Electromagnetic Therapy sessions plus a traditional physiotherapy program for 8 weeks. The Control Group: Will receive sham High-Intensity Focused Electromagnetic Therapy sessions plus the same traditional physiotherapy program for 8 weeks.

20-30 minute sessions, 2-3 times per week for 8 weeks at a clinically effective, tolerable intensity level designed to elicit supramaximal contractions for the quadriceps muscle.
The device protocol, application time, and acoustic feedback will the same as the experimental arm, but with the device in the off state and no muscular contractions in the quadriceps muscle .
Standard rehabilitation program including patellar mobilization with quadriceps and hip abductor strengthening.
Pain level
Visual Analog Scale will be used to assess pain
Time frame: Baseline and after 8 weeks
Quadriceps muscle strength
Isokinetic dynamometry will be used for assessing quadriceps muscle strength
Time frame: Baseline and after 8 weeks
Health-related quality of life
Short Form-12 Health Survey (SF-12) will be used to assess QoL
Time frame: Baseline and after 8 weeks
