Abstract

Background : We experience many cases complaining of chronic dizziness in our Department of Psychosomatic Medicine. In many of them, we find a physical disorder like secondary hypertonic contraction of neck muscles. However many cases tend to suffer from alexisomia and lack subjective symptoms. In these cases, physical feedback is suggested to modulate their cognitive ability. We investigated the usefulness of intervation of experience-based awareness which makes the cases with chronic dizziness be aware of the existence of hypertonic contraction of neck muscles by hypnosis-induced muscle relaxation. Method : Fifty-six cases complaining of dizziness and hypertonic contraction of neck muscles for longer than 3 months were enrolled to the study. On the first visit, they were divided into two groups, alternately, in the order of entry, i.e. 28 hypnosis vs 28 non-hypnosis cases. Thereafter, we explained that hypertonic contraction of neck muscles was one of the causes of dizziness and progressive muscle relaxation was introduced. In two groups, the degree of dizziness was monitored chronologically by Numerical Rating Scale. Results: In both groups, significant changes in Numerical Rating Scale were observed (p<0.001) In both groups, changes between the first visit and the state 1-month later were significant (p<0.001). In contrast, changes between the first and the third month were not significant. In the hypnosis group, Numerical Rating Scale of dizziness between the first visit and the state 1-month later was not significantly lower than that in non-hypnosis group (p=0.029). Numerical Rating Scale of dizziness between the first visit and the third month was significantly lower (p=0.005). Conclusion : In the hypnosis group, the improvement was greater than that in the non-hypnosis group. This implies that experience-based awareness by hypnosis on the first visit leads to the improvement of dizziness. Experience-based awareness is supposed to stimulate the cases to recognize a relation between subjective physical disorder and chronic dizziness and may be a beneficial approach to treat alexisomia.
