Table 2 Descriptive data of quantitative sensory testing (QST) thresholds before (pre) and during hypnosis according to individual hypnotic susceptibility

From: Hypnotic relaxation results in elevated thresholds of sensory detection but not of pain detection

  LH pre hypnosis LH during hypnosis LMH pre hypnosis LMH during hypnosis HMH pre hypnosis HMH during hypnosis HH pre hypnosis HH during hypnosis
