Open Access Abstract Background Analysis of rhythmic patterns embedded within beat-to-beat variations in heart rate heart rate variability is a tool used to assess the balance of cardiac autonomic nervous activity and may be predictive for prognosis of some medical conditions such as myocardial infarction. It has also been used to evaluate the impact of manipulative therapeutics and body position on autonomic regulation of the cardiovascular system. However few have compared cardiac autonomic activity in supine and prone positions postures commonly assumed by patients in manual therapy. We intend to redress this deficiency. Methods Heart rate heart rate variability and beat-to-beat blood pressure were measured in young healthy non-smokers during prone supine and sitting postures and with breathing paced at Hz. Data were recorded for 5 minutes .
