The Wilcoxon signed-rank test revealed significant differences (95% CI, A within-group comparison of mean outcomes scores of VAS, NDI, SF-ROM, and PPT in Group 1, using a Wilcoxon signed-rank test (two-tailed, N = 15).NDI = neck disability index, SF-ROM = cervical side flexion (unaffected side) range of motion, PPT = pain pressure threshold, VAS = visual analog scale, Z = Z statistics.Significant value if A within-group comparison of mean outcomes scores of VAS, NDI, SF-ROM, and PPT in Group 2, using a Wilcoxon signed-rank test (two-tailed N = 15).NDI = neck disability index, SF-ROM = cervical side flexion (unaffected side) range of motion, PPT = pain pressure threshold, VAS = visual analog scale, Z = Z statistics.Significant value if
