  Title Immediate effects of atlas manipulation on cardiovascular physiology
Journal Clin Chiropr. 2012 Dec;15(3-4):147-157
Peer Review Yes
Publication Type Article

Objective: The aims of this study were (1) to determine if there were any statistically significant immediate effects of atlas Chiropractic Manipulative Therapy (CMT) on cardiovascular physiology among normotensive individuals and (2) to quantify those responses if they were found.

Design: A single-blind, randomized controlled trial.

Setting: Human physiology lab.

Subjects: Forty-eight college students (age = 25.9 ± 3.4 years, height = 1.70 ± 0.10 m, body mass = 76.2 ± 20.1 kg: mean ± SD) were sampled in this study.

Methods: Participants were equally randomized into four study groups: left head-turn control, no contact control, left atlas manipulation, and right atlas manipulation. The CMT provided was a cervical break. Electrocardiogram (ECG), bilateral pulse oximetry, and bilateral blood pressure measurement were performed at baseline, post 1-min intervention, post 10-min intervention, and approximately post 24-h (±1 h) intervention. Between-group dependent variables were analyzed through one-way analysis of variance (ANOVA) at each time point.

Results: No statistically significant difference was shown among any between-group cardiovascular dependent variables in this study.

Conclusions: The results of this research suggest cardiovascular physiology is not affected by CMT of the atlas in normotensive individuals. These findings in relation to existing research suggest future cervical spine CMT studies should be performed focusing on hypertensive patients.
