Postural and Head Control Given Different Environmental Contexts

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 role of head stability in postural control development

Vestibulocollic reflexes in the absence of head postural control.

Percutaneous electrical vestibular stimulation evokes reflexive responses in appendicular muscles that are suppressed during tasks in which the muscles are not contributing to balance control. In neck muscles, which stabilize the head on the torso and in space, it is unclear whether similar postural task dependence shapes vestibular reflexes. We investigated whether vestibulocollic reflexes are...

Vestibulocollic reflexes in the absence of head postural 5 control

50 Percutaneous electrical vestibular stimulation evokes reflexive responses in appendicular 51 muscles that are suppressed during tasks where the muscles are not contributing to balance 52 control. In neck muscles, which stabilize the head on the torso and in space, it is unclear if 53 similar postural task dependence shapes vestibular reflexes. We investigated whether 54 vestibulocollic refle...

Falls and postural control in older adults with cataracts

Background: There is increasing evidence that visual impairment contribute to falling. The aim of this study was to determine the influence of vision impairment of old adult patients with cataract on the occurrence of falls and postural control. Methods:According to the results of screening ophthalmic examination, 48 cataract patients (mean±SD aged 68.5 ± 6.08 yrs.) and 50 individuals withou...
