The purpose of this study was to evaluate a sensorimotor assessment and rehabilitation apparatus (SARA) during multiple analogs of space flight (parabolic flight, bed rest, Human Exploration and Research Analog – HERA, and the NASA Extreme Environment Mission Operations - NEEMO). SARA encompasses a battery of behavioral sensorimotor assessment tests that monitor posture, gait, dynamic visual acuity (DVA), and binocular misalignments. The goals of implementing SARA in the HERA were to validate SARA testing in an operational setting (including the ability to self-administer the SARA tests) and to explore changes in sensorimotor function following prolonged exposure to isolated and confined environments. This experiment is a continuation of a study titled, "Sensorimotor Assessment and Rehabilitation Apparatus: Procedures and Equipment" with Mark Shelhamer as the PI.

Specific Aims:

  1. Evaluation of the overall feasibility of using SARA in multiple analogs to space flight (i.e. bed rest, HERA, NEEMO)
  2. Evaluation of the sensitivity of SARA in assessing sensorimotor function as altered by changing gravity conditions.
  3. Evaluation of subject comfort while performing the tasks, especially when making head movements in multiple orientations and multiple g-levels.
