Postural sway in first-degree relatives of individuals with schizophrenia

Postural control deficits are well documented in schizophrenia. However, postural stability has not been assessed in first-degree relatives of individuals with schizophrenia to our knowledge. We analyzed postural sway in 27 controls (CTR) and 18 …

Postural sway correlates with cognition and quality of life in Parkinson’s disease

We measured postural sway in individuals diagnosed with Parkinson's disease and age-matched controls. Individuals with Parkinson's swayed more, as expected, especially when their eyes were closed. In the people with Parkinson's, sway correlated strongly with cognitive measures, as well as with measures of quality of life and clinical status.

Cerebellar–cortical dysconnectivity in resting‐state associated with sensorimotor tasks in schizophrenia

Abnormalities of cerebellar function have been implicated in the pathophysiology of schizophrenia. Since the cerebellum has afferent and efferent projections to diverse brain regions, abnormalities in cerebellar lobules could affect functional …

Postural Sway

Postural sway can be measuresd using a force plate or balance plate (or even a mobile phone accelerometer or a Nintendo Wii). This is a place for all the projects I am involved in that utilise postural sway.

Postural stability predicts the likelihood of cybersickness in active HMD-based virtual reality

Cybersickness is common during virtual reality experiences with head-mounted displays (HMDs). Previously it has been shown that individual differences in postural activity can predict which people are more likely to experience visually-induced motion …

Postural sway abnormalities in schizotypal personality disorder

We measured postural sway in individuals diagnosed with schizotypal personality disorder, but otherwise free of medication and other comorbidities. They swayed significantly more than matched controls, and as much as people dignosed with schizophrenia, in all conditions.

Disturbances of postural sway components in cannabis users

A prominent effect of acute cannabis use is impaired motor coordination and driving performance. However, few studies have evaluated balance in chronic cannabis users, even though density of the CB1 receptor, which mediates the psychoactive effects …

The Shepard--Risset glissando: music that moves you

Sounds are thought to contribute to the perceptions of self-motion, often via higher-level, cognitive mechanisms. This study examined whether illusory self-motion (i.e. vection) could be induced by auditory metaphorical motion stimulation (without …

Chaos in balance: non-linear measures of postural control predict individual variations in visual illusions of motion

Visually-induced illusions of self-motion (vection) can be compelling for some people, but they are subject to large individual variations in strength. Do these variations depend, at least in part, on the extent to which people rely on vision to …

Spontaneous postural sway predicts the strength of smooth vection

This study asked whether individual differences in the influence of vision on postural stability could be used to predict the strength of subsequently induced visual illusions of self-motion (vection). In the experiment, we first measured spontaneous …
