High Frequency RF Current Effects on Muscle Pain and Function
Acute and Chronic Effects of High Frequency RF Electrical Current on Pain and Muscle Function in Individuals With Musculoskeletal Pain
Aristotle University Of Thessaloniki
160 participants
Apr 30, 2022
INTERVENTIONAL
Conditions
Summary
The purpose of this study is to examine the acute and chronic effects of high frequency electrical current transfer (frequently called "TECAR") on pain and functional movement in individuals with a musculoskeletal injury or pain. The participants will be assigned into an experimental or a control group and outcome measures will be measured prior to, after, 24 and 48 hours following a single intervention session (Acute effects) as well as 3 and 6 months after the intervention (chronic effects).

Interventions
Radiofrequency Electrical Currents (TECAR) will be delivered using a winback system (Winback, Villeneuve-Loubet, France) propagating radiofrequency waves of 448 kHz using metallic electrodes via a coupling medium. Radiofrequencies will be used in the capacitive mode , which aims to treat superficial /soft tissues in the area. The "active" plate will be applied sequentially on the skin in the injured or painful region. The base plate will be located to the other side of the injured body region (for back thigh muscle injuries, for example, the base plate will be located on the frontal thigh area, to close the current circuit. Therapy will be applied for 20 minutes, with a target intensity of 40% and a frequency of 0.5Mhz.
Transcutaneous nerve stimulation (TENS) will be delivered using a Chattanooga Intellect Advanced Combo system (Chattanooga, Hixson, TN 3 7343, USA). Two electrodes will be placed on the skin at a distance so that they cover the entire painful area. The TENS asymmetric biphasic mode (phase 300 ms, frequency 80Hz, continuous cycle) will be applied. The intensity will be adjusted between 0 and 110A, such that it is tolerable by the participant. The total application time will be 20 minutes or equal to that applied for the TECAR group.
