Delay and Acceleration Threshold of Movement Perception in Patients Suffering from Vertigo or Dizziness.

Background: The objective was to evaluate the delay and the acceleration threshold (AT) of movement perception in a population of patients suffering from dizziness and analyze the factors influencing these parameters.

Methods: This prospective study included 256 adult subjects: 16 control and 240 patients (5 acute unilateral vestibular loss, 13 compensated unilateral loss, 32 Meniere diseases, 48 persistent postural-perceptual dizziness (PPPD), 95 benign paroxysmal positional vertigo (BPPV), 10 central cases, 19 bilateral vestibulopathy, 14 vestibular migraine, and 4 age-related dizziness). Patients were evaluated for the sound-movement synchronicity perception (maximum delay between the bed oscillation peak and a beep perceived as synchronous, PST) and AT during a pendular movement on a swinging bed.

Measuring threshold and latency of motion perception on a swinging bed.

Introduction: Our objective was to develop and to evaluate a system to measure latency and threshold of pendular motion perception based on a swinging bed.

Materials And Methods: This prospective study included 30 healthy adults (age: 32 ± 12 years). All subjects were tested twice with a 10 min.
