[Status of the sensory sphere in schizophrenic patients with a cenestopathic-hypochondriacal syndrome].

The state of and interrelations between the kinesthetic and visual sensitivity were studied in 70 patients and 24 normal subjects by using the technique of parallel-sequential sensometry suggested by A. V. Zavyalov. At 30 sec intervals at the constant baseline irritation, 16 thresholds of weight differentiation and 16 thresholds of brightness differentiation were registered. The results were subjected to the correlational and informational analysis. It was established that hyposensitivity of the sensory systems studied was accompanied with the weakening of direct and strengthening of the inverse optical-kinesthetic correlation, the absence of the functional predominance of the kinesthetic analyzer over the visual one, low orderliness of the parameters of the interanalyzer relationship and a sharp liability of the intersensory correlation to the effect of the heterosensory irritant. Changes in the systemic organization of the sensory sphere seem to be responsible for various cenesthopathies.
