TI  - Short-term vestibular responses to repeated rotations in pilots.
PG  - 285-7
AB  - INTRODUCTION: [corrected] It has been suggested that vestibular function in 
      pilots differs from that of non-pilots. METHODS: Short-term vestibular responses 
      to repeated rotations were explored in pilots and non-pilots using a rotating 
      chair. Vestibulo-ocular reflex tests were done in 30 pilots (VOR-P) and 30 
      non-pilots (VOR-NP) at rotation frequencies of 0.01, 0.02,0.04, 0.08, 0.16, and 
      0.32 Hz. In a separate experiment, VOR tests were done at 0.16 Hz before and 
      after four successive velocity-step tests in twenty-five pilots (STEP-P) and 
      their results were compared with the results of twenty-five non-pilots (STEP-NP) 
      who were studied earlier. RESULTS: VOR-P exhibited normal VOR gains (mean values 
      0.47, 0.57, 0.63, 0.69, 0.67, and 0.74, respectively, for the frequencies listed 
      above) compared with those of VOR-NP (0.48, 0.54, 0.59, 0.67, 0.72, and 0.79). 
      VOR gain at 0.16 Hz showed little change in STEP-P (0.64 +/- 0.04 to 0.58 +/- 
      0.032), while it increased in STEP-NP (0.59 +/- 0.03 to 0.78 +/- 0.06). 
      DISCUSSION: VOR gain may be a useful measurement for differentiating pilots' 
      vestibular function from that of non-pilots. After-rotary VOR may be suppressed 
      in pilots.
