Effect of Pulsed Electromagnetic Field Therapy as an Adjunct Modality to Warm-up Exercise

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

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 20 (actual)
• Sponsor: Chinese University of Hong Kong · Academic / Other
• Sex: All
• Age: 18 Years – 40 Years
• Healthy volunteers: Accepted

Summary

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.
