Brief Summary

The most important regulatory system in the body is the autonomic nervous system. There are several studies that evaluate the effect of techniques applied at the base of the skull on the autonomic nervous system. The aim of this study is to evaluate the effect of the flying buttress technique on the autonomic nervous system.

Detailed Description

The most important homeostatic regulatory system in the body is the autonomic nervous system (ANS), as it coordinates functions of many organs and tissues, including the cardiac muscle.

ANS regulation in most visceral organs reflects a balance between sympathetic and parasympathetic modulation. In the neural control of the heart, there is a balance between sympathetic excitation and vagal inhibition of sinoatrial node activity, which contribute to fluctuations in heartbeat, known as heart rate variability (HRV).

HRV is considered a valuable non-invasive measurement tool for assessing ANS function, as it is relatively simple and quickly performed.

Previous studies provide evidence that osteopathic treatment is associated with changes in HRV that appear to be indicative of increased cardiac vagal modulation in various conditions.

The aim of this study is to evaluate the effect of the osteopathic technique flying buttress on the ANS through HRV.

Control groupPlacebo techniqueIn each participant, HRV will be measured for 2 minutes, then the placebo technique will be applied. After the technique, HRV will be recorded for 2 minutes, and 5 minutes later, HRV will be measured again for 2 minutes.
Experimental groupFlying buttress techniqueIn each participant, HRV will be measured for 2 minutes, then the flying buttress technique will be applied. After the technique, HRV will be recorded for 2 minutes, and 5 minutes later, HRV will be measured again for 2 minutes.
