Patellofemoral Pain Syndrome
Conditions
Brief summary
Evaluate the effect of High-Intensity Focused Electromagnetic Therapy on pain, quadriceps strength, and quality of life in patients with patellofemoral pain syndrome
Detailed description
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.
Interventions
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.

Eligibility
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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain level | Baseline and after 8 weeks | Visual Analog Scale will be used to assess pain |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quadriceps muscle strength | Baseline and after 8 weeks | Isokinetic dynamometry will be used for assessing quadriceps muscle strength |
| Health-related quality of life | Baseline and after 8 weeks | Short Form-12 Health Survey (SF-12) will be used to assess QoL |
