Data are shown as mean ± standard deviation. Abbreviations: CG = control group; EG = experimental group; T0 = baseline measurement; T1 = post-treatment measurement; T2 = 1-month follow-up measurement; SCM = Sternocleidomastoid; a VAS of the last week; b algometry shows the measurements for both sides (kg/cm2); * significant differences (p < 0.05) compared to T0; † significant differences (p < 0.05) compared to T1; and bold indicates significant differences (p < 0.05) between groups. Cohen’s d effect size was calculated for comparisons where statistically significant differences were obtained.
