The human postural coordination mechanism is an example of a complex closed-loop control system based on multisensory integration [9,10,13,14]. In models of this process, sensory data from vestibular, visual, tactile and proprioceptive systems are integrated as linearly additive inputs that drive multiple sensory-motor loops to provide effective coordination of body movement, posture and alignment [5-8, 10, 11]. In the absence of normal vestibular (such as from a toxic drug reaction) and other… Expand

Sensory substitution for balance control using a vestibular-to-tactile device.
TLDR
The results of two studies suggest that an individual with double partial foot amputation was able to improve his balance control thanks to the use of a vestibular-to-tongue tactile biofeedback balance system and that young healthy individuals were able to take advantage of it to reduce the postural destabilisation induced by plantar-flexor muscle fatigue.

To make sense of our unpredictable world, humans use sensory information streaming through billions of peripheral neurons. Uncertainty and ambiguity plague each sensory stream, yet remarkably our… Expand
Efficacy of electrotactile vestibular substitution in patients with bilateral vestibular and central balance loss
TLDR
The results demonstrate consistent positive and statistically significant balance rehabilitation effects independent of aging and etiology of balance deficit. Expand
Effectiveness of an electro-tactile vestibular substitution system in improving upright postural control in unilateral vestibular-defective patients.
TLDR
Results, demonstrating the effectiveness of the EVSS system in improving upright postural control in unilateral vestibular-defective patients, could have implications in clinical and rehabilitative areas. Expand
Potential Mechanisms of Sensory Augmentation Systems on Human Balance Control
TLDR
A critical review summarizes the reported sensory augmentation findings spanning postural control models, clinical rehabilitation, laboratory-based real-time usage, and neuroimaging to critically evaluate each of the aforementioned mechanistic theories. Expand
Closed Loop Kinesthetic Feedback for Postural Control Rehabilitation
TLDR
A closed loop control of the Center-Of-Pressure (CoP) based on kinesthetic feedback is proposed as a new form of biofeedback and the robustness of this approach is evaluated under experimental conditions that are more realistic with regards to the clinical context of a rehabilitation program involvingBiofeedback-based exercises.

Efficacy of electrotactile vestibular substitution in patients with peripheral and central vestibular loss.
TLDR
A pilot study to test the effectiveness of training with the BrainPort balance device in subjects with a balance dysfunction due to peripheral or central vestibular loss, showing consistent positive and statistically significant improvements in balance, posture and gait. Expand
Auditory biofeedback substitutes for loss of sensory information in maintaining stance
TLDR
The results support the hypothesis that the nervous system uses augmented sensory information differently depending both on the environment and on individual proclivities to rely on vestibular, somatosensory or visual information to control sway. Expand
How Performing a Repetitive One-Legged Stance Modifies Two-Legged Postural Control
TLDR
Data show that the motor systems control body motions better after repetitive stimulation of the sensory cues and should be of interest in physical activities based on a precise muscular length control. Expand
Can an electro-tactile vestibular substitution system improve balance in patients with unilateral vestibular loss under altered somatosensory conditions from the foot and ankle?
TLDR
Preliminary results suggest that patients with unilateral vestibular loss were able to take advantage to a head position-based electro-tactile tongue biofeedback to mitigate the postural perturbation induced by alteration of somatosensory input from the foot and the ankle. Expand

A multisensory integration model of human stance control
TLDR
It is concluded, that the model is capable of studying and quantifying multisensory integration in human stance control and should be applied in the design and development of prostheses and orthoses and the diagnosis of neurological balance disorders. Expand
Multisensory information for human postural control: integrating touch and vision
TLDR
It is suggested that the sensory fusion process behaved in an approximately linear fashion because the experimental paradigm tested postural control very close to the equilibrium point of vertical upright. Expand

Position and velocity coupling of postural sway to somatosensory drive.
TLDR
Fitting of a linear second-order model to the data suggests that postural control parameters are not fixed but adapt to the moving frame of reference, and coupling to both position and velocity suggest that a spatial reference frame is defined by the somatosensory system. Expand
An adaptive model of sensory integration in a dynamic environment applied to human stance control
TLDR
The model results suggest that vestibular-related thresholds are the result of the processing of noisy sensory and motor output signals, and suggests that the environment postural orientation can not be estimated optimally, which causes sensory illusions. Expand

TLDR
Findings show that during quiet stance light touch of the index finger with a stationary surface can be as effective or even more so than vestibular function for minimizing postural sway. Expand
Somatosensory loss increases vestibulospinal sensitivity.
TLDR
Evidence is provided for an increase in the sensitivity of the postural control system to vestibular stimulation when somatosensory information from the surface is disrupted either by peripheral neuropathy or by standing on an unstable surface. Expand
