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.

Inclusion Criteria:

• Clinical diagnosis of patellofemoral pain syndrome (anterior or peripatellar knee pain aggravated by at least two activities such as stair climbing, prolonged sitting, squatting, or running).
• Symptoms persisting for at least 3 months.

Exclusion Criteria:

• History of previous knee surgery or trauma (e.g., ligamentous laxity, meniscal tear, or patellar fracture).
• Concomitant knee pathology (e.g., tibiofemoral osteoarthritis, patellar tendinopathy, or plica syndrome).
• Presence of metallic implants, pacemakers, or electrical medical devices in the body .
• Recent corticosteroid or hyaluronic acid injection into the affected knee within the last 3 months.
• Pregnancy.
