Health-related quality of life
Baseline and after 8 weeks
Study Arms (2)
Study group
ACTIVE COMPARATORControl group
SHAM COMPARATORInterventions
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 Criteria
You may qualify if:
- 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.
You may not qualify if:
- 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.
