Description

Initial State of Gap: Individual astronauts show significant diversity in their ability to adapt to gravitational transitions.  Tests to identify individuals who experience particular difficulty with microgravity and partial gravity sensorimotor adaptation do not exist.

Target for Gap Closure: Develop pre-flight tests to identify individual capacity to produce adaptive change (rate and extent) in sensorimotor function (as defined in SM 2.1) and produce customized sensorimotor training prescriptions that target the specific needs of each crew member based on their individual adaptive characteristics.

Interim steps:
1.Review information gathered as tasks are completed under sensorimotor gaps SM2.1, SM6.7, SM7.1, and SM26.
2.Develop a battery of tests and measures to identify individual capacity to produce adaptive change in sensorimotor function.
3.Conduct ground studies to verify efficacy of test battery as a predictive measure of sensorimotor adaptability using a novel discordant sensory environment.
4.Develop individualized training prescriptions based on predictive metrics.
5.Conduct ground studies to verify efficacy of individualized training prescriptions to increase sensorimotor adaptability.
6.Conduct flight studies to verify efficacy of test battery as a predictive measure of sensorimotor adaptability and to verify individualized training prescriptions. 
7.Transition to Operations.

Approach: Perform tests that will delineate individual sensory biases in tests of visual, vestibular and proprioceptive function. Measure individual differences in regional brain volumes, white matter integrity, functional network integrity, and sensorimotor adaptation task-related functional brain activation. Determine if, together, these metrics predict how quickly subjects adapt to a novel discordant sensory environment and if individualized training prescriptions based on predictive metrics can be used to optimize sensorimotor adaptability training countermeasures (SM28).

Target for Closure
Develop pre-flight tests to identify individual capacity to produce adaptive change (rate and extent) in sensorimotor function (as defined in SM 2.1) and produce customized sensorimotor training prescriptions that target the specific needs of each crew member based on their individual adaptive characteristics.
