About this study
Ultrasound-guided infiltration is a common procedure and is known to be locally painful. This care-induced pain leads to strong apprehension in patients who need to benefit from this procedure.
The practice of hypnosis to improve the patient's comfort during a treatment has appeared progressively in hospital departments.
Among the various existing conversational hypnosis techniques, there is the "magic glove" technique. This is the technique that will be used in this study.
The investigators wish to evaluate the interest of hypnosis on the pain felt by the patient when performing an echo-guided infiltration of the hand, one of the most painful extremities during infiltrations.
