N2 - Objective: The purpose of this study was to investigate the immediate effects of cervical spine manipulation (SM) compared with muscle energy technique (MET) on neck muscle activity and range of motion in asymptomatic people. Methods: A randomized parallel-group study was conducted at a chiropractic teaching clinic in Durban, South Africa. Fifty asymptomatic participants between 18 and 35 years of age were randomly assigned into group 1 or group 2. Group 1 received cervical SM, and group 2 received MET. Participants were blinded to group allocation only. Baseline and post-test measurements consisted of resting upper trapezius and posterior cervical muscle activity and cervical spine range of motion (ROM) in lateral flexion and extension. Results: A significant difference was found in cervical ROM within groups (P <.001), with no significant difference observed between the 2 groups. The right posterior cervical muscles showed a significant difference in group 1 only (P =.012). No significant muscle activity changes occurred in group 2. Resting muscle activity measures showed no statistically significant changes between groups. Conclusion: A single application of SM and MET to the cervical spine immediately increased cervical ROM. Neither cervical SM nor MET changed resting posterior cervical and upper trapezius muscle activity.
