Standing balance control relies on multisensory feedback, but little is known about the influence of periodically varying sounds on this process. The level of sensorimotor activation has been shown to be highly correlated with the concept of musical groove. We presented musical stimuli with high and low groove ratings to participants (N=40) as center of pressure (CoP) was recorded using a force...

BACKGROUND The aim of this study was to quantify postural control ability in a group with concussion compared with a healthy control group. METHOD Fifteen concussion patients (4 females, 11 males) and a group of fifteen age- and sex-matched controls were recruited. Participants were tested during the performance of the three stance variants (bilateral, tandem and unilateral) of the balance er...

Upright stance in humans is inherently unstable, requiring corrective action based on spatial-orientation information from sensory systems. One might logically predict that environments providing access to accurate orientation information from multiple sensory systems would facilitate postural stability. However, we show that, after a period in which access to accurate sensory information was r...

Low Back Pain (LBP) is commonly classified as civilization disease. Many authors assume that about 80% of the population over forty have at least one major episode pain in lumbar area. those patients demonstrate lumbosacral radicular symptoms. Sciatica usually develop a result disc-root conflict and can disturb posture balance. The objective this study was to assess effect visual biofeedback ba...

Abstract Background The capacity of postural control is a key factor related to falling in older people, particularly women with low back pain (LBP). Cognitive involvement increases age. However, most scholars have not considered different difficulty levels cognitive loads when exploring the effects cognition on patients LBP. present study investigate how modulate Methods This was cross-section...

The problem of how the nervous system fuses sensory information from multiple modalities for upright stance control remains largely unsolved. It is well established that the visual, vestibular, and somatosensory modalities provide position and rate (e.g., velocity, acceleration) information for estimation of body dynamics. However, it is unknown whether any particular property dominates when mu...

The purpose of this study was to assess the influence of electrotactile feedback on postural control performance during binaural galvanic vestibular stimulation (GVS). Postural equilibrium was measured with a computerized hydraulic platform in 10 healthy adults (6M, 4F, 24-65 y). Feedback of anterior-posterior (AP) and mediallateral (ML) body sway was derived from a 2-axis linear accelerometer ...

Postural sway is considered to have two fundamental stochastic components, a slow non-oscillatory component and a faster damped-oscillatory component. The slow component has been shown to account for the majority of sway variance during quiet stance. Postural control is generally viewed as a feedback loop in which sway is detected by sensory systems and appropriate motor commands are generated ...

INTRODUCTION There is evidence that increased ambient pressure causes an increase in postural sway. This article documents postural sway at pressures not previously studied and discusses possible mechanisms. METHODS Eight subjects participated in a dry chamber dive to 240 msw (2.5 MPa) saturation pressure. Two subjects were excluded due to unilateral caloric weakness before the dive. Postural...
