“…In the future, studies combining postural measures and specific vestibular and visual rehabilitative therapy for Usher patients will be necessary to assess the progress and improvement of these patients objectively. Moreover, studies could investigate treatment approaches using invasive- or non-invasive vestibular prosthetics for potential use in such patients to improve their quality of life (41).…”

This study investigated postural performances and vestibular impairment in Usher patients. The three groups studied were: 11 patients with Usher type I (with visual and vestibular impairment), 14 patients with Usher type II (with only visual impairment), and 14 healthy control subjects. Postural stability was measured with a Framiral Multitest Equilibre platform with three visual conditions: eyes open (EO), eyes closed (EC), and vision disturbed by optokinetic stimulation (OPT), and two different postural conditions: stable or unstable platform. The surface and mean velocity of the center of pressure displacement (CoP) were measured and a postural instability index (PII) was calculated. Usher type I and II patients were more unstable than control subjects, but only for the unstable platform. Patients with Usher type I (with severe vestibular impairment) were also significantly more unstable than patients with Usher type II (with normal vestibular function) on the unstable platform. The severity of the vestibular impairment was correlated with the surface of the CoP displacement. We suggest that poor postural control of Usher patients is due to the abnormalities in their visual and, when defective, vestibular inputs. Measurements of postural stability on an unstable platform can distinguish type I from type II Usher patients. We emphasize the importance of multisensory evaluation in these patients to guide development of personalized visuo-vestibular rehabilitation techniques to improve their postural stability and improve their quality of life.

“…An emerging area of vestibular research is looking into surgically implanted vestibular prostheses, which generate electrical signals based on head motion that are delivered to the ampullary nerves [76]. Vestibular implants/prostheses work by replacing the lost natural afferent spike activity in the vestibular nerve with electrical stimulation [4]. Vestibular implants take advantage of MEMS gyroscopes and accelerometers to provide head movement signals to trigger the stimulators [77].…”

“…On the other hand, bilateral hypofunction is loss or diminished function on both right and left. People with bilateral vestibular impairments in the US and Europe are approximately 500,000-700,000, with the figures reportedly downplayed due to the difficulty in diagnosis [4]. Vestibular loss is mainly common among the elderly.…”

The vestibular system is dedicated to gaze stabilization, postural balance, and spatial orientation; this makes vestibular function crucial for our ability to interact effectively with our environment. Vestibular hypofunction (VH) progresses over time, and it presents differently in its early and advanced stages. In the initial stages of VH, the effects of VH are mitigated using vestibular rehabilitation therapy (VRT), which can be facilitated with the aid of technology. At more advanced stages of VH, novel techniques that use wearable technologies for sensory augmentation and sensory substitution have been applied to manage VH. Despite this, the potential of assistive technologies for VH management remains underexplored over the past decades. Hence, in this review article, we present the state-of-the-art technologies for facilitating early-stage VRT and for managing advanced-stage VH. Also, challenges and strategies on how these technologies can be improved to enable long-term ambulatory and home use are presented.
