Efficacy of Focused ESWT and Dry Needling Among Patients With Myofascial Pain Syndrome of the Upper Trapezius Muscle

Myofascial pain syndrome (MPS) is one of the most common causes of musculoskeletal pain. Among patients with MPS, the upper trapezius muscle appears to be the common muscle that generates pain in the area of upper extremity. The main target treatment for MPS is to eradicate the painful trigger points by using treatment options, such as ultrasound, laser, and dry needling (DN). In the past decade, focused extracorporeal shockwave therapy (fESWT) has become the well-known treatment for pain relief in various musculoskeletal pain conditions. The main advantages of this non-invasive treatment modality are reducing pain, inflammation and promoting tissue healing. However, there were no previous studies compared effects of fESWT to dry needling. Therefore, the present study aims to compare the efficacy of the two treatments in terms of pain reduction and functional improvement.
