*Friedman ANOVA, level of significance (before vs after vs 1-month follow-up vs 3-months follow-up). **Kruskal-Wallis ANOVA, level of significance (HILT vs HILT (p) vs LLLT vs LLLT (p) group). SD: standard deviation; HILT: high-intensity laser therapy group; HILT (p): high-intensity laser therapy sham group; LLLT: low-level laser therapy group; LLLT (p): low-level laser therapy sham group.
