The aim of this study was to compare the effect of the central posteroanterior mobilization to the thoracic rotary posteroanterior manipulation on pain and active cervical range of motion in the treatment of bilateral mechanical neck pain. Sixty patients with bilateral mechanical neck pain with mean aged (SD) 43.8 (11.8) years were recruited. The subjects were randomly allocated into either cervical mobilization or thoracic manipulation group using concealed envelopes. The outcome measurements investigated in this study were active cervical range of motion, pain intensity, and global perceived effect. Oneway ANOVA was use to investigate the effectiveness of spinal manipulative therapy between two groups. Paired t-test was used to investigate the effectiveness of spinal manipulative therapy within group. No statistically significant pain reduction and improving active cervical range of motion noted between two groups (p > 0.05). However, statistically significant pain reduction both at rest and on most painful movement noted within groups (p<0.01).
