Comparing electrical stimulation and physical therapy for knee pain

Official title: A Prospective Randomized Study Comparing the Outcome of Electrical Stimulation of Vastus Medialis Obliquus Muscle and Physical Therapy vs Only Physical Therapy But no Electrical Stimulation in Patients With Patellofemoral Pain Syndrome

Run by Northwell Health · NCT03184545 · Data updated 2026-11-12

This study is testing if using an electrical stimulation device along with physical therapy can help people with knee pain recover faster and feel better compared to just physical therapy alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 18 to 40 with bilateral or unilateral anterior knee pain lasting more than three months and specific pain-related criteria.

Probably not a fit

Patients with a history of knee surgery, patellar dislocation, or other significant knee pathologies may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of an electrical muscle stimulation (EMS) device in conjunction with physical therapy for patients suffering from patellofemoral pain syndrome, commonly known as anterior knee pain. Participants will be divided into two groups: one receiving EMS along with physical therapy, and the other receiving physical therapy alone. The goal is to determine if the addition of EMS accelerates recovery and improves outcomes compared to standard physical therapy. The EMS device used is FDA approved and has shown promise in treating knee-related conditions. This study aims to include a larger patient population to validate previous findings that were limited by small sample sizes.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with patellofemoral pain syndrome, potentially leading to faster recovery times.

How similar studies have gone: Previous studies have shown mixed results with similar approaches, indicating the need for further investigation with larger sample sizes.
