Can Osteopathy and Expiratory Resistance be Used in Prevention and/or Treatment of Acute Mountain Sickness ? a Randomized Controlled Field Study

Brief Summary

      The purpose of this research is to support a hypothesis that osteopathic manual medicine
      (OMM) and / or a 10 cmH2O end-expiratory pressure (PEEP) could be used in the prevention of
      acute mountain sickness (AMS).

      During altitude exposure, an exaggerated hypoxemia and the increase of intracranial pressure
      are both known to be major physipathological ways of AMS development.

      The goal of the osteopathic protocol is to release tension on the circulatory structures
      directly related to cranial circulation and drainage. The main hypothesis is that it could
      lead to lower intracranial pressure and help reducing AMS signs. Furthermore the
      investigators would like to define a osteopathic score for individual AMS sensitivity, based
      on cranial bones mobility.

      Several studies have shown that using PEEP at altitude (or hypoxia) increases SpO2. As for
      osteopathy protocol, the investigators would like to apply this experimental condition during
      real altitude exposure in a randomized controlled protocol.
