[State of peripheral circulation in the late stages of vibration disease]

The paper is concerned with a description of the results of polyrheovasographical studies in 102 patients with late stages of vibrational disease. The authors distinguished 3 variants of vascular disturbances: hypertonic, hypotonic, dystonic. The cold test detected in most of the patients changes of the vascular reactivity in the form of increased, decreased and--less frequently--inverse reactions to this stimula. The conclusion is made that polyrheovazographical studies permit to clarify the character and degree of the expressiveness of vascular disorders in most of the patients with vibrational disease which is very important for defining the stage of the disease and the assessment of the working capacity in this contingent.
