简要总结
Hypnotic glove anesthesia is a hypnosis technique wherein the patient, following the suggestions of the hypnotherapist, is mentally capable to create a loss of sensation in areas of the hand that would be covered by a glove. We investigated the effects of hypnotic glove anesthesia on skin temperature measured by thermography.
详细描述
After 20 min installation and temperature equilibration (T0), the subject skin temperature was recorded in 5 regions of both hands (1 = distal hand, 2 = proximal hand, 3 = wrist, 4 = distal forearm, 5 = proximal forearm) using infrared thermography.
After 10 min of latency, skin temperature was recorded again in both hands (T1).
A first noxious stimulus (NOX1) is then applied by the hypnotherapist by pinching the webbing between the thumb and index fingers of the dominant hand between the thumb and the index. Pain intensity is assessed on a 0-10 (0 = no pain, 10 = maximal pain imaginable) numerical rating scale (NRS1).
The hypnotic glove is then mentally created by the subject on his dominant hand following the suggestions of the hypnotherapist (T2). To assess the efficacy of the hypnotic glove, a second noxious stimulus (NOX2) is applied similarly to NOX1 and the NRS was recorded (NRS2).
The subject is then invited to mentally wear off the glove (T3). Skin temperature is then recorded in both hands, and a third noxious stimulus (NOX3) is applied similarly to NOX1 and NOX2 to verify the disappearance of hypnotic anesthesia.

结局指标
主要结局
Change in skin temperature during the experiment in the hand and forearm
时间窗: During the study experiment, from the beginning of the experiment, after 20 min installation and temperature equilibration, to the end of the experiment, 5 min after the glove is mentally withdrawn (approximately 1 h).
Comparison of skin temperature between the dominant ("wearing" the hypnotic glove) and the non-dominant hand and forearm in the 5 predefined regions from Time 0 to Time 4.
次要结局
- Change in pain intensity during the experiment following noxious stimulation(During the study experiment, from 10 min after the beginning of the experiment to 5 min before the end of the experiment, when the glove is mentally withdrawn (approximately 45 min).)
