Popis:	A comparative study of nociceptive sensitivity of the skin in 115 men (51 healthy and 64 with neurasthenia, a natural model of chronic psychoemotional stress) was undertaken with the aid of focused ultrasound. The group of patients revealed a distinct tendency for lowering of the pain threshold, weakening of adaptation to repeated presentation of a nociceptive stimulus of threshold strength, and sensitization. When these deviations were found in subjects, they were found to have a pain syndrome relatively more often. Since exposure to focused ultrasound of fairly high intensity involves primarily C afferents (not only cutaneous but also visceral nociceptors), it is suggested that the changes in nociceptive sensitivity observed in patients with neurasthenia are not confined to the skin, but extend also to the internal medium, facilitating the formation of a pain syndrome.
