Position Statement: Rotational (Rotary) Chair Testing

The American Academy of Otolaryngology—Head and Neck Surgery recognizes that the following tests are medically indicated and appropriate in the evaluation of certain persons with suspected balance or dizziness disorders:

  1. Rotational chair step velocity testing
  2. Rotational chair sinusoidal harmonic acceleration testing
  3. Rotational chair high frequency or high velocity sinusoidal rotation
  4. Rotational chair rotation with visual fixation
