Deficits in motor control, often accompanied by loss of muscle strength, have been reported after space flight. These deficits contribute to the inability to produce coordination patterns associated with maintaining upright posture. Posutre disequilibrium can greatly hamper prompt egress from a vehicle after space flights, particularly those of moderate or long duration. In conjunction with NASA's Extended Duration Orbiter Medical Project, the Motor Performance laboratory is working to develop in-flight countermeasures that prevent loss of muscle strength and movement coordination and protect these abilities at landing.
