Patients with phobic postural vertigo (PPV) often report a particularly increased unsteadiness when looking at moving visual scenes. Therefore, the differential effects of large-field visual motion stimulation in roll plane on body sway during upright stance were analyzed in 23 patients with PPV, who had been selected for the integrity of their vestibular and balance systems, and in 17 healthy subjects. Visual motion stimulation induced a sensation of apparent body motion (roll vection) in all… 

Spontaneous visual exploration during locomotion in patients with phobic postural vertigo

Gaze control of locomotion in patients with PPV is characterized by a preferred deviation of gaze more downward and by horizontal explorations for suitable auxiliary means for potential postural support in order to prevent impending falls.

Phobic Postural Vertigo

Rehab has to be pointed to restore correct integration between special and general proprioception and the correct internal representation of posture in order to recover appropriate balance strategies.

Phobic postural vertigo: body sway during vibratory proprioceptive stimulation

Phobic postural vertigo patients are more sensitive to proprioceptive disturbances than healthy subjects are, and less apt to use visual information to control upright stance, which might be part of an anxious mode of balance control.

Postural control during galvanic vestibular stimulation in patients with persistent perceptual–postural dizziness

GVS may be helpful to identify thresholds of vestibular perception and to modulate vestibulo-spinal reflexes in PPPD, with dissociable effects with respect to perceptible and imperceptible stimuli.

Posturographic profile of patients with persistent postural-perceptual dizziness on the sensory organization test.

Patients with PPPD had difficulties with postural control across multiple sensory challenges, consistent with postulated neurophysiologic mechanisms of this condition.

Vestibular function in panic disorder patients: a vestibular-evoked myogenic potentials and video head impulse test study

The VEMPs and vHIT tests demonstrated that there is no evidence of hypofunction of the semicircular canals in the high-frequency spectrum of VOR functioning, and there are no indications of impairment of the otolith system in patients with PD, regardless of their subjective vestibular sensations.

本邦におけるPhobic postural vertigo (恐怖性姿勢めまい) 症例について

The diagnosis of PPV was important to improve the prognosis because the key for a correct diagnosis is not anxiety but the subjective dizziness itself, and an obsessional personality is often observed.

In patients with visual vertigo, the presence of additional CNS or strabismic symptoms may cause inappropriate postural reactions in environments with conflicting or disorienting visual stimuli, probably by reducing the ability to resolve the sensory conflict.

Despite a considerable rate of improvement in vertigo complaints, the group of patients with phobic postural vertigo as a whole presented with significant psychological problems at follow‐up term, requiring specific psychiatric and/or psychotherapeutic interventions.

A survey among 116 crew members of seagoing vessels confirmed that mal de debarquement (M-D) is a transient feeling of swinging, swaying, unsteadiness, and disequilibrium, and it is suggested that M-D represents a dynamic, multisensorimotor form of CNS adaptive plasticity.
