Low-level laser for treatment of XXXX : a self-controlled clinical trial.

@entity1 @entity392
BACKGROUND: Despite the high prevalence and morbidity, @entity392 remains an obscure symptom. We assessed the efficacy of low-level laser for treatment of @entity392 . METHODS: It was a self controlled clinical trial study on 61 outpatients with subjective @entity392 . The @entity1 were irradiated with a 650-nm, 5-mW soft laser for twenty days and twenty minutes per day. The sensation of @entity392 was measured on a Visual Analog Scale (VAS) before and two weeks after treatment and they were compared by means of Wilcoxon signed ranktest. RESULTS: Thirty-eight (62.3%) @entity1 were @entity1 and twenty-three (37.7%) were @entity1 . Fourteen @entity1 (31.8%) worked in noisy environment. The VAS mean difference before and after the treatment was statistically significant (p < 0.0001). The best treatment effect was in the youngest group and there were significant differences between this group and the middle age and older groups (p = 0.018 and 0.001, respectively). The mean VAS score reduction was not statistically significant between male and female @entity1 (p = 0.23). Also, the treatment outcome according to the noise level in @entity1 's workplaces was not significantly different in @entity1 (p = 0.693), but it was significant in @entity1 (p = 0.029). CONCLUSIONS: Transmeatal low-level laser irradiation is effective for the treatment of @entity392 and some variables like age and job can affect the treatment outcome.
