Protocol Overview. A) Diagrammatic representation of the relative chair position over the course of each cycle. B) Representation of movement into the pitch-forward position during centrifugation. Subjects were oscillated back at forth and 5 frequencies to produce sufficient centripetal acceleration to create corresponding gravitoinertial acceleration (GIA) that produced similar perceptions of tilt to the pitch-tilt chair protocol.
