Name Time Method Change in the vestibulospinal reflex threshold. The reflex threshold will be determined by a psychometric test procedure. Accordingly, the vestibulospinal reflex responses (trunk movements) to a vestibular stimulus (sinusoidal galvanic vestibular stimulation (1 Hz)) at varying amplitudes (0 to 1.9 mA) will be measured (by means of motion sensors attached to the forehead and chest) and the smallest stimulus amplitude that elicits a reflex response will be psychometrically determined. This amplitude will be defined as the vestibulospinal reflex threshold. The threshold test lasts for ~ 5 minutes.
