The objective of the experiment was to evaluate the participants' ability to detect painful zones by palpating with their hands.

Greg's method for detecting pain involved pressing on muscles to find tension points that would reproduce the subjects' pain and observing their defensive reactions, such as spasms or avoiding movement.

Healthcare professionals can differentiate a very hard zone from a softer zone, feel skin texture and temperature, and detect a person's heart rhythm with their hands.

Lisa, a newly graduated physio, was the second most successful at locating subjects' painful areas, followed by Flavien, and then Viviane.

Viviane from Scilabus and Greg from Major Mouvement conducted an experiment in the south of France to test what could be deduced from simple palpation of people's backs.
