研究概览
简要总结
The goal of this clinical trial is to assess the effectiveness of pulsed electromagnetic field therapy as an adjunct to warm-up exercises, in healthy participants. Researchers will investigate both the immediate effect of one round of pulsed electromagnetic field therapy (PEMF) and after a warm-up exercise, on participants' range-of-motion (ROM) at the knee and quadriceps' muscle stiffness, measured through shear wave elastography, an ultrasound technique. This may be useful in future interventions to protect against sports injuries.
Participants will have their knee ROM and quadriceps' muscle stiffness measured thrice, once at baseline, once after PEMF/sham treatment, and once after 5 minutes of warm-up stationary bike exercises.
Researchers will compare with sham treatment to see if there are any significant effects from PEMF therapy.

Participants will have their knee ROM and quadriceps' muscle stiffness measured thrice, once at baseline, once after PEMF/sham treatment, and once after 5 minutes of warm-up stationary bike exercises.
- Baseline measurement of knee ROM and quadriceps' muscle stiffness
- Receive PEMF for ten minutes around their knee joint
- Interim measurement of knee ROM and quadriceps' muscle stiffness
- Perform 5 minutes of warm-up exercise on a stationary bike
- Final measurement of knee ROM and quadriceps' muscle stiffness
Researchers will compare with sham treatment to see if there are any significant effects from PEMF therapy.

结局指标
主要结局
Change in knee range-of-motion from baseline immediately after PEMF and after warm-up exercise, as assessed by goniometer
时间窗: From before PEMF/sham treatment to end of treatment and warm-up exercise, within 1 hour
A goniometer will be used to measure the knee range-of-motion: the static arm will follow a line joining the knee to the greater trochanter of the femur, and the moving arm a line from the knee to the lateral malleolus of the ankle
次要结局
- Change in quadriceps muscle stiffness from baseline immediately after PEMF and after warm-up exercise, as assessed by ultrasound shear wave elastography(From before PEMF/sham treatment to end of treatment and warm-up exercise, within 1 hour)
