Efficacy of Osteopathic Visceral Treatment in Patients With Chronic Neck Pain

"Diaphragm Stretching:~The participant is seating down and the researcher will be behind, placing their hands on the inferior costal border. Cephalic traction is performed during inhalation, remaining during exhalation. Procedure is repeated 2 times, for 10 respiratory cycles, with 1-minute intervals.~Inferior Mobilization of the Stomach:~The participant is seating down with slight flexion of the torso, while the investigator stands behind them, placing the thumbs on the epigastric region. The volunteer will extend their body while the researcher performs a caudal traction. This procedure lasts 5 minutes.~Liver Pump:~Participant is laying on their back, and the investigator is standing on the participants side. The researcher places one hand on the right side inferior costal border posteriorly and the other one bellow the costal border anteriorly. Researcher compresses during exhalation and releases their hands abruptly during inhalation. This procedure lasts 5 minutes."

In this group, techniques are the exact same as described previously but only liver and stomach ones will be performed.

In the sham group, manual contact without any therapeutic intention will be performed in the same regions as the experimental groups. This contact will be maintained during the same amount of time as for the experimental group A.
