Pulsed Radiofrequency vs Dry Needling in Myofascial Pain

Myofascial pain (MPS) is the leading cause of chronic and persistent regional pain, affecting as many as 85% of the general population. A variety of treatment methods for myofascial pain have been investigated, including injection of saline, local anesthetics and steroids, dry needle, mini-scalpel, rich platelet plasma and radiofrequency ablation. Ultrasound guided dry needle (DN) and pulsed radiofrequency ablation (PRF) of the trigger point have been considered as two effective and promising treatments for myofascial pain. As far as searched, we failed to identify any study comparing the effects of DN and PRF in myofascial pain patients.
