Dynamic study of postural tremor in high pressure conditions

Tremor holds a central place in the high pressure nervous syndrome generated by hyperbarism, a fact that prompted us to carry out this study. We found that tremor appears after diving to a depth of 150 m (16ATA) and progressively intensifies with the increase of pressure. We discuss the pathogenic mechanism in which, besides the involvement of several central mechanisms, one can also incriminate some peripheral ones (probably the change of interstitial pressure at the nerve and/or muscle level).
