Patients with vestibular loss diagnosed by senior ENT doctors with the gold standard ENT measures (caloric testing, head impulse test and/or vestibular evoked myogenic potential, ocular and cervical)

People with no vestibular loss

To evaluate walking abilities, participants performed the Timed-Up & Go (TUG) f our times (practice trial, normal, slow and fast speed). Patient's performances are videorecorded with an Intel RealSense depth camera D435i to capture their movements, and manual time recording of time taken (in seconds) and number of steps are carried out by the experimenters.

Complementary to manual experimenter recording, a 2D human pose estimation method (OpenTUG) is applied to automatically extract the time and the number of steps taken by the participant during the TUG task.

evaluation to assess attention (Test for Attentional Performance -TAP-) Alertness and Divided attention tasks. Median reaction time and standard deviation of the median (regularity) are record in milliseconds. Slow reaction times and large standard deviations indicate more difficulties.

evaluation to assess quality-of-life (DHI -Dizziness Handicap Inventory, Jacobson & Newman, 1990, Demanez 1991) 25-items, each scored on a 5-point Likert scale. Covering three main areas of difficulties: functional, physical, and emotional aspects related to dizziness and instability.

Higher scores = higher complains

evaluation to assess quality-of-life (Anxiety and depression symptoms, measured with the French version of the Hospital Anxiety and Depression Scale (HADS) (Zigmond & Snaith, 1983), using a 14-item self-assessed questionnaire, each with a 4-point response Likert scale.

Higher scores = higher complains

evaluation to assess subjective perception of cognitive difficulties associated to vertigo with the Neuropsychological Vertigo Inventory - NVI (Lacroix et al., 2016), using 28-items, each scored on a 5-point Likert scale and divided into 7 distinct subscales measuring attention, memory, emotion, space perception, time perception, vision, and motor abilities.

Higher scores = higher complains

Participants performed the Timed-Up & Go (TUG) four times (practice trial, normal, slow and fast speed). They have to stand up from a chair, walk until a line on the ground marked at 3 meters, turn, go back to the chair, and sit down again. The time is recorded. There is no time limit to the task.
