Effectiveness of Pulsed Electromagnetic Field Therapy as an Adjunct Modality to Warm-up Exercise: a Randomized Controlled Trial

This clinical trial is designed to evaluate whether pulsed electromagnetic field therapy (PEMF) can enhance the benefits of warm-up exercises in healthy individuals. The focus is on improving the range-of-motion in the knee and reducing muscle stiffness in the quadriceps, which are key factors in preventing sports injuries. By analyzing the immediate effects of a single PEMF session combined with a warm-up exercise, this study aims to uncover potential new methods for protecting against injuries during physical activities. Participants in the study undergo several measurements to assess their knee flexibility and muscle stiffness. Initially, these measurements are taken without any treatment. Then, participants receive a ten-minute PEMF treatment around their knee, followed by another set of measurements. After this, they engage in a five-minute warm-up session on a stationary bike, with a final round of measurements taken afterwards. The outcomes of the PEMF treatment are compared to a sham treatment to determine its effectiveness, using a special ultrasound technique called shear wave elastography to ensure accurate results.
