Clinical test results and treatment recommendations.

Vestibular function test results	Abnormal Calorics: 43% Abnormal cVEMPs: 48% Abnormal rotational chair: 54% Abnormal positional: 22% Bilateral dysfunction: 26%
Treatment recommendations	Physical therapy: 73% Canalith repositioning maneuver: 13% Change diet: 13%

cVEMP: cervical Vestibular Evoked Myogenic Potential

Abnormal caloric test: > 24% asymmetry or total eye speed < 20 deg/sec

Abnormal VEMP test: asymmetry > 29% or absent response

Abnormal rotational chair test: reduced gain, phase lead, or directional preponderance

Abnormal positional test: slow phase velocity > 4 deg/sec (> 6 deg/sec for age >65)
