Electromyographic investigations of tremor in aquanauts during simulated immersions.

Electromyographic investigations of tremor in aquanauts under the conditions of stimulated immersions are presented in this paper. The investigations were carried out before the aquanauts entered a barochamber, at specific pressure levels in the barochamber, under the conditions of decompression, and following emergence from the barochamber. The observed manifestations of the tremor under the conditions of increased pressure of trimix exhibited characteristics of parkinsonian tremor.
