Limitations of postural equilibrium tests for examining simulator sickness.

摘要: The psychometric properties of four ataxia tests and their sensitivities to disorientation were examined assess potential for measuring balance disturbances frequently reported with simulator sickness. study was conducted in two parts. In the first, subjects practiced 10 sessions examine learning effects stabilize performance. second, by comparing performance before after exposure sensory conflict produced using a training flight simulator. Subjective measures disorientation, including reports postural disequilibrium, also collected. results indicated initial on all measures. Two tests, Stand One Leg Eyes Closed Sharpened Romberg, exhibited acceptable levels reliability. However, only latter showed sufficient sensitivity corroborate subjective disequilibrium.
