Short Title: DEFERRED: Sensorimotor Countermeasure Suite
Responsible HRP Element: Human Health Countermeasures
Collaborating Org(s):
Flight Analogs Project (FAP)
Research Operations and Integration (ROI)
Funding Status: Terminated - A formerly active task that was stopped before its completion date due to deselection, descoping, reorganization etc.
Procurement Mechanism(s):

This task was deferred by HRP Program Management and was terminated when new science strategies were developed. Appropriate aims of the study will be included in future CM development studies. 

1. Develop a sensorimotor countermeasure suite designed to reduce post landing postural and locomotor dysfunction. The countermeasure suite will be comprised of two integrated countermeasure approaches including pre-flight sensorimotor adaptability training and inflight posture training. We will use a phased-in approach in terms of countermeasure implementation. The preflight sensorimotor adaptability training will be phased-in first on an initial set of subjects (group 1). A second group of subjects will then be tested that will receive both the preflight sensorimotor adaptability training and the inflight posture training (group 2). We will then be able to compare the efficacy of the sensorimotor adaptability training alone with that of a combined training protocol that includes both preflight adaptability training and the inflight posture training.


2. Test the efficacy of the countermeasure suite to reduce post landing postural and locomotor dysfunction. To save on flight resources, the control subjects for this study will consist of astronauts that previously participated in the Functional Task Test (FTT) and Field Test (FT) experiments prior to the implementation of our countermeasure suite. We will use a sub-set of tests from the FTT and FT studies that showed the greatest changes in functional performance due to balance and locomotor alterations.
