Abstract
INTRODUCTION: Myofascial pain syndrome (MPS) is a neuromuscular dysfunction consisting of both motor and sensory abnormalities. Considering the high prevalence of MPS and its related disabilities and costs, this study was designed to determine the reliability of new ultrasonographic indexes of the upper trapezius muscle as well as the sensitivity and specificity of 2D ultrasound imaging for diagnostic purposes. Furthermore, we sought to evaluate the effectiveness of dry needling (DN) on studied ultrasonographic indexes.
MATERIALS AND METHODS: This study will be performed in two steps with two different designs. The first is a pilot study and was designed as a semi-experimental study to determine the sensitivity and specificity of ultrasonography for the diagnosis of MPS and the reliability of ultrasonographic measurements like muscle thickness, area of myofascial trigger points (MTrPs) in longitudinal view, echogenicity of MTrPs in longitudinal view, echogenicity of muscle with MTrPs in longitudinal and transverse views, and pennation angle of upper trapezius muscle. The second study is an interventional study which was designed to investigate the effectiveness of DN on ultrasonographic measurements, for which the reliability was determined in the first study.
CONCLUSION: we will quantify the effectiveness of DN on MTrPs and muscle tissue by using novel ultrasonographic indexes. The results of the current study will provide baseline information to design more interventional studies to improve the evaluation of other treatments of MPS.
