ASA S3.45 – American National Standard Procedures for Testing Basic Vestibular Function

Scope

This Standard specifies procedures for conducting six separate tests, which, together with the dataanalysis and reporting requirements specified in this Standard, constitute the Basic VestibularFunction Test Battery. The six tests cover:

(a) spontaneous nystagmus (see 5.2);
(b) gaze-evoked nystagmus (see 5.3);
(c) saccade test (see 6);
(d) pursuit testing (see 7);
(e) positioning and positional nystagmus (see 8); and
(f) caloric testing (see 9).

Each of these tests evaluates a response of the vestibular system by the vestibulo-ocular reflexthrough the measurement of electrical signals generated by eye movements recorded by electrooculography.
