Treatment of Upper Trapezius Muscle Myofascial Pain Syndrome

Myofascial Pain Syndrome (MAS) is a common condition encountered in the daily practice of musculoskeletal medicine. Dry needling is a commonly used technique by clinicians in the treatment of myofascial trigger points. Dry needling can be classified into two main categories based on the depth of needle insertion: superficial and deep dry needling. Dry needling can be performed using either manual palpation techniques or ultrasonographic imaging. Ultrasound allows for more precise needle placement. It must be recognized that the depth of needling (superficial insertion vs. deep insertion) varies for every structure and that without ultrasound guidance, differentiation between needling into the superficial fascia and beyond the deep fascia maybe difficult. In clinical settings, using ultrasound can help visualize the different layers and guide the needle to the appropriate depth. The aim of this study is to compare the effectiveness of deep fascia and intramuscular trigger point dry needling techniques, guided by ultrasound, on pain, disability, functional impairment, and quality of life in patients diagnosed with myofascial pain syndrome of the upper trapezius muscle.
