[The pain sensitivity of the skin in chronic psychoemotional stress in man].
The focused ultrasound has been used for the comparative study of skin sensitivity to pain in 51 healthy men and 64 patients with neurasthenia, natural model of the chronic psycho-emotional stress. The patients showed a distinct tendency to a decrease of the pain threshold, lowered adaptation to the repeated threshold stimulus, sensitization. With the presence of the above-mentioned factors the pain syndrome occurred relatively more often. Taking into account the fact that the focused ultrasound of rather high intensity affects, first of all, C-afferents which are not only cutaneous but visceral nociceptors as well, an assumption is made that changes in pain sensitivity in the neurasthenic patients are not limited by skin but develop also in the inner medium forming the pain syndrome.
