Summary

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.

Conditions

  • Myofacial Pain Syndromes

Interventions

DEVICE

Intravascular laser irradiation of blood (ILIB)

continuous-wave ILIB is performed using a 632.8nm (red light) laser beam from a He-Ne laser machine (Y-J ILIB-5, Bio Human Energy Cooperation, New Taipei City, Taiwan, R.O.C.).The participants sit on a sofa with their arms relax and supported on the table. A 24-gauge catheter is inserted to a superficial vein in upper extremity under sterile preparation, and an optic fiber channel is connected to the catheter for blood irradiation.

DEVICE

Transcutaneous electrical nerve stimulation

TENS over neck for 15 minutes.

OTHER

Stretching exercise

stretching exercise to the involved muscle for 15 minutes.
