Ultrasonography in Diagnosis of Myofascial Pain Syndrome and Reliability of Novel Ultrasonic Indexes of Upper Trapezius Muscle.
Myofascial pain syndrome (MPS) is a common non-articular musculoskeletal disorder. It is characterized by local and referred pain due to the presence of myofascial trigger points (MTrPs). MTrPs most commonly involve the upper trapezius muscle and can be visualized using ultrasound imaging. This study was designed to determine the inter-rater reliability of some new ultrasonographic indices of the upper trapezius muscle and the sensitivity and specificity of 2D ultrasound imaging in the diagnosis of MPS. ⋯ 1. Our findings indicated that ultrasonography is a useful method for the diagnosis of MPS owing to its high sensitivity. 2. Appropriate reliability of the quantitative ultrasonographic indices of interest, especially the area of MTrPs and their echogenicity, could be useful for long-term monitoring and designing interventional studies for better management of the syndrome.
