Brief summary (from the registry)
Myofascial pain syndrome (MPS) is characterized by single or multiple trigger points (TrP) in taut bands within the affected muscles. Chronic MPS over neck is prevalent and responsible for markedly loss of work-day and a reduction of quality of life. Intravascular laser irradiation of blood (ILIB) involves in vivo illumination of the blood by low-level laser light through an optical fiber inserted in a vein. Researches disclosed that ILIB reduced blood viscosity, enhanced erythrocyte deformity, and increased oxygen saturation in blood. However, no research studies the effectiveness of ILIB to treat MPS. Real-time sonoelastography (RTS) and shear wave velocity (SWV) are used to detect the stiffness of skeletal muscles. RTS is displayed as a color-coded graphic to represent the relative stiffness of structures. For a given material, faster SWV indicates the greater stiffness. To our knowledge, only one research using RTS and SWV to study MPS. To elucidate the effectiveness of ILIB to treat chronic MPS over neck, and the validity of RTS and SWV for MPS, we conducted this study.
