Tilt Determination in MEMS Inertial Vestibular Prosthesis

Journal of Biomechanical Engineering, 2006
Background: There is a clear need for a prosthesis that improves postural stability in the balance impaired. Such a device would be used as a temporary aid during recovery from ablative inner-ear surgery, a postural monitor during rehabilitation (for example, hip surgery), and as a permanent prosthesis for those elderly prone to falls.

Optical nerve stimulation for a vestibular prosthesis

SPIE Proceedings, 2009
Infrared Nerve Stimulation (INS) offers several advantages over electrical stimulation, including more precise spatial selectivity and improved surgical access. In this study, INS and electrical stimulation were compared in their ability to activate the vestibular branch of the VIII th nerve, as a potential way to treat balance disorders.

Development of a biophysical model for vestibular prosthesis research

Journal of Vestibular Research, 2003
Physiologic properties of primary vestibular neurons are compared and contrasted with properties of primary auditory neurons. The differences and similarities suggest possible coding strategies for a vestibular implant. The degree of spike rate variability, or coefficient of variation (CV), is a prominent physiological property of vestibular neurons ...

Chronic Vestibulo-Ocular Reflexes Evoked by a Vestibular Prosthesis

IEEE Transactions on Biomedical Engineering, 2007
We are developing prosthetics for patients suffering from peripheral vestibular dysfunction. We tested a sensory-replacement prosthesis that stimulates neurons innervating the vestibular system by providing chronic pulsatile stimulation to electrodes placed in monkeys' lateral semicircular canals, which were plugged bilaterally, and used head angular ...

Stimulation management for a multichannel vestibular neural prosthesis

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
This paper describes the stimulation management unit for a multichannel vestibular neural prosthesis. The unit is designed as part of a stimulator ASIC in the implantable subsystem of the prosthesis. This digital unit provides the stimulator ASIC the ability to generate biphasic current pulses at specified amplitude, duration and pulse rate to drive ...

A closed-loop neural prosthesis for vestibular disorders

10th Symposium on Neural Network Applications in Electrical Engineering, 2010
Vestibular disorders can cause severe problems including nausea, inability to concentrate, and visual deficits. The CLONS project is developing a closed-loop sensory neural prosthesis to alleviate these symptoms. Conceptually, the prosthesis restores vestibular information by stimulating the semicircular canals according to measurements from inertial ...

An integrated vestibular-cochlear prosthesis for restoring balance and hearing

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
An integrated vestibular-cochlear implant can be rapidly prototyped and clinically tested by modifying an existing modern cochlear implant. The modifications include addition of gyroscope sensors and reallocation of several electrodes that are normally used for auditory nerve stimulation to the semicircular canals, while sharing the external DSP ...

A noninvasive vibrotactile stimulator prosthesis for bilateral vestibular dysfunction

2013 First International Symposium on Future Information and Communication Technologies for Ubiquitous HealthCare (Ubi-HealthTech), 2013
Patients with bilateral vestibular disease (BVD) often present a severe balance disability and treatment of BVD disease is complex and time-consuming. Patients can be treated with balance retraining exercises but the improvement is not likely to be full recovery.
