Objective: Low intensity carbon dioxide laser has been used to the therapeutic modality for various musculoskeletal pain while there are little evidences about the treatment effect. We aimed to evaluate the efficacy of low intensity carbon dioxide laser therapy on musculoskeletal pain.
Method: Thirty patients with musculoskeletal pain were recruited and randomly assigned to one of two groups. Treatment group was administered with laser for 20 minutes on the site of pain. Placebo group was administered as the same manner but with laser power off state. Visual analogue scale for pain intensity was measured before treatment, immediately after, and 20 minutes after the treatment.
Results: Baseline pain intensity was same between the two groups (p=0.866). Changes of pain intensity immediately and 20 minutes after the treatment were not statistically different between the two groups (p=0.123 and p=0.328, respectively).
Conclusion: Low intensity carbon dioxide laser therapy on the musculoskeletal pain was not efficacious.
