STS-55 Pilot Henricks with baroreflex collar in SL-D2 module onboard OV-102
STS055-233-019 (26 April-6 May 1993) --- Terence T. (Tom) Henricks, STS-55 pilot, wears a special collar for a space adaptation experiment in the science module onboard the Earth-orbiting Space Shuttle Columbia. The Baroreflex (BA) experiment is designed to investigate the theory that light-headedness and a reduction in blood pressures upon standing after landing may arise because the normal reflex system regulating blood pressure behaves differently after having adapted to a microgravity environment. These space-based measurements of the baroreflex will be compared to ground measurements to determine if microgravity affects the reflex.
