The Orbital Workshop internal arrangement shown here is the medical experimental equipment. In this view, looking from the wardroom area, are the lower-body Negative Pressure (Experiment M092) unit, left, and the ergometer for the vectorcardiograph (Experiment - M093). Both are used in several ways to keep check on the astronauts' condition and tolerance in extended weightlessness. The 1-G trainer permits the astronauts to get experience with all of the equipment and operations except the absence of gravity.
