Study of the Impact of Gastric Interoceptive Signals on the Body Schema Via the Water Load Test II ( GIBS) (GIBS)

Study of the Impact of Gastric Interoceptive Signals on the Body Schema Via the Water Load Test II

The aim of this study was to evaluate whether gastric interoceptive information has a direct impact on the motor and tactile dimensions of the body schema.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
modification of the body schema in its motor and tactile dimensions	The primary endpoint is composite and corresponds to the two differences in SKIN and MOVE scores, measured before and after the gastric interoceptive activation task, which assess the integrity of the body pattern.; The SKIN score is the average difference (in mm) between the actual deviation applied to the shoulder and belly skin and the estimated deviation reported by the participant.; MOVE score is the average ratio between the minimum distance (in mm) between virtual balls thrown at a person's shoulders and belly and from which they are avoided, and the actual morphology of this person at the point where the bullets pass (actual body width in mm).	before and within 10 minutes after gastric interoceptive activation task (day 1)
