Summary

Objective: To compare the effectiveness of application of low-level laser therapy (LLLT) to trigger points and traditional acupoints for patients with cervical myofascial pain syndrome (MPS).

Design: A single-blinded, randomized, placebo-controlled trial Setting: University rehabilitation hospital Participants: One hundred and twenty one patients with cervical MPS Intervention: The investigators performed this experiment using low level 810-nm gallium aluminum arsenide (Ga-Al-As) laser. One hundred participants were randomly assigned to four treatment groups, including (1) acupoint therapy (2) acupoint control (3) trigger point therapy and (4) trigger point control groups.

Main Outcome measures: The investigators evaluated the patient's visual analogue scale (VAS) pain scores, pressure pain threshold and cervical range of motion (ROM) before and after the therapy.
