Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental group
In 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.
Flying buttress technique
With the volunteer in a supine position, the researcher who applied the technique positioned himself standing at the head of the massage table, supporting the patient's head. He contacted the occipital region, near the occipital-mastoid suture, with the thenar and hypothenar region of his right hand. He contacted the mastoid process of the contralateral temporal bone with the thenar and hypothenar region of his left hand. The forearms were positioned in a straight line. After a slight initial compression, the researcher applied a rhythmic pumping motion with both upper limbs in a convergent direction. The pressure applied was due to the rhythmic movement of the researcher's body. The technique was performed bilaterally and each one lasted for 2 minutes
Control group
In 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.
Placebo technique
With the volunteer in a supine position, the researcher placed the palms of their hands on the patient's shoulders. The palm of the hand rested on the acromioclavicular joint with the rest of the hand relaxed. The placebo technique was performed for 4 minutes.
