研究目的
To assess the effects of low-level laser therapy (LLLT) on pain in women with TMDs and whether knowledge of the treatment received influenced their pain perception.
研究成果
Average levels of pain decreased more than 4 points in both groups immediately after LLLT sessions. After 6 months and 1 year, pain levels increased in both groups to a level slightly lower than before treatment.
研究不足
The RCT had a high risk of bias. The researchers did not describe a comparison of all prognostic factors that could have affected the outcome. One-third of the participants enrolled were lost to follow-up.
1：Experimental Design and Method Selection:
The researchers conducted a randomized clinical trial (RCT) to assess the effects of LLLT on pain in women with TMDs.
2：Sample Selection and Data Sources:
66 women with a diagnosis of myofascial pain of muscular origin for at least 3 months were enrolled.
3：List of Experimental Equipment and Materials:
Gallium-aluminum-arsenic laser (Twin Laser, MMOptics).
4：Experimental Procedures and Operational Workflow:
Participants were assigned to receive LLLT or a placebo LLLT.
5：Data Analysis Methods:
Pain levels were measured using a 10-point visual analog scale.
