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… Expand

Decreased postural adaptation in patients with phobic postural vertigo—An effect of an “anxious” control of posture?
TLDR
The results support the hypothesis that a cognitive set of posture, an "anxious control", may underlie the symptoms of PPV, i.e. an increased readiness to react to any perturbation or deviation. Expand
Reduced postural differences between phobic postural vertigo patients and healthy subjects during a postural threat
TLDR
Patients with phobic postural vertigo exhibit an increased high-frequency sway in posturographic tests, but their postural sway becomes similar to the sway of healthy subjects during difficult balance tasks, which may be due to an already maximized postural adaptation. Expand
Phobic postural vertigo: body sway during vibratory proprioceptive stimulation
TLDR
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. Expand
Visual vertigo: symptom assessment, spatial orientation and postural control.
TLDR
The results indicate that VV emerges in vestibular patients if they have increased visual dependence and difficulty in resolving conflict between visual and vestibulo-proprioceptive inputs and it is argued that treating these patients with visual motion desensitization, e.g. repeated optokinetic stimulation, should be beneficial. Expand
Gait characteristics of patients with phobic postural vertigo: effects of fear of falling, attention, and visual input
TLDR
The view that the gait characteristics of PPV can be attributed to an inadequate, cautious gait control is supported, indicating a higher reliance of patients on visual information during walking. Expand
Postural control during galvanic vestibular stimulation in patients with persistent perceptual–postural dizziness
TLDR
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. Expand
Treatment of phobic postural vertigo
In balance clinic practice, phobic postural vertigo is a term used to define a population with dizziness and avoidance behavior often as a consequence of a vestibular disorder. It has been describedExpand
Inadequate interaction between open- and closed-loop postural control in phobic postural vertigo
TLDR
Stabilogram diffusion analysis (SDA) data indicate that subjective imbalance in PPV is associated with characteristic changes in the coordination of open- and closed-loop mechanisms of postural control. Expand
Psychological assessment in patients with phobic postural vertigo.
TLDR
Adaptive compromise was observed in individuals with PPV which was shown to be associated to psychiatric disorders. Expand
One-year follow-up of cognitive behavioral therapy for phobic postural vertigo
TLDR
Cognitive behavioral therapy has a limited long-term effect on phobic postural vertigo, more difficult to treat than panic disorder with agoraphobia, and Vestibular rehabilitation exercises and pharmacological treatment might be the necessary components of treatment. Expand

Phobic postural vertigo. Body sway during visually induced roll vection.
TLDR
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, and the data support the second explanation. Expand
Patients with somatoform phobic postural vertigo: the more difficult the balance task, the better the balance performance
TLDR
Objective balance skills were not impaired in patients with PPV during balance tasks at the limits of postural control and body sway activity and sway path values did not differ between patients and controls. Expand
Phobic postural vertigo: body sway during vibratory proprioceptive stimulation
TLDR
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. Expand
Phobic Postural Vertigo
TLDR
Although an association of PPV with anxiety disorders is evident, not all patients present with symptoms of anxiety or panic during attacks of vertigo, and most patients develop a disabling “phobic/avoidance pattern” (Kapfhammer et al. 1997). Expand

TLDR
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. Expand
Course of illness in phobic postural vertigo
TLDR
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. Expand
Phobic postural vertigo: a new proposed entity.
TLDR
Patients diagnosed with phobic postural vertigo presented with complaints of unsteadiness with or without dizziness, and attacks of sudden veering that caused them to grasp for support that led to effective treatment. Expand

TLDR
Its hallmark is fear of absent visuospatial support (open spaces) and of falling, unlike the fear of public places found in agoraphobia, and better understanding of the pathogenesis may illuminate how anxiety produces some physical symptoms. Expand
