Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in Lake Louise Score from baseline to altitude continuous exposure.	Signs of acute mountain sickness regarding its severity according the official Lake Louise Score.	mesured and reported every hour during a 10 hours altitude exposure
Secondary	Changes in numeric scale of well being from baseline to altitude continuous exposure.	Quantification of general feeling on a scale from 0 (feeling as before ascent) to 10 (worst feeling)	every hour during a 10 hours altitude exposure
