Influence of Visual Field on Postural Control

Influence of Hemianopic Visual Field Loss on Visual Motor Control

BACKGROUND Homonymous hemianopia (HH) is an anisotropic visual impairment characterized by the binocular inability to see one side of the visual field. Patients with HH often misperceive visual space. Here we investigated how HH affects visual motor control. METHODS AND FINDINGS Seven patients with complete HH and no neglect or cognitive decline and seven gender- and age-matched controls view...

Effect of visual stimulus using central and peripheral visual field on postural control of normal subjects

[Purpose] This study investigated the effects of visual stimulus using central and peripheral vision fields on postural control. [Subjects and Methods] The subjects consisted of 40 young adult volunteers (15 males, 25 females) who had been informed of the study purpose and procedure. The subjects were randomly divided into four groups of differing visual stimulus. Each group was given visual in...

Influence of Sensory Dependence on Postural Control

The Influence of Different Visual Stimuli and Head Movement on the Control of Postural Sway

Visual, proprioceptive and vestibular systems clearly contribute to postural control, as several studies have shown that visual [1] proprioceptive [2] or vestibular [3] stimulation evokes and controls body sway. Each sensory system detects an “error”, indicating a deviation in the body’s orientation from a reference position. The visual system is considered to be the most complex [4] of the sen...

The influence of total knee arthroplasty on postural control.

INTRODUCTION The aim of this study is to assess the changes induced by the unilateral total knee arthroplasty procedure in human postural control. MATERIALS AND METHODS The measurements were performed using the "AMTI AccuGait" force plate. Subjects completed three consecutive double-limb standing balance trials. The mediolateral and anteroposterior displacements were derived from the force an...
