Summary
The Automated Vestibular Rehabilitation System (AVRS) shows moderate reliability for measuring VOR gain, offering a more accessible approach to vestibular rehabilitation therapy (VRT). This technology could improve dizziness and vertigo treatment accessibility.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Vestibular rehabilitation therapy (VRT) is effective for dizziness and vertigo but faces accessibility challenges.
- Automated systems offer a potential solution to increase VRT accessibility.
Purpose of the Study:
- To evaluate the feasibility and performance of the Automated Vestibular Rehabilitation System (AVRS), a machine vision-based VRT alternative.
- To assess the accuracy and reliability of AVRS in measuring vestibular function.
Main Methods:
- Forty adults completed a standard VRT exercise (X1) using AVRS in seated and standing positions.
- AVRS tracked head and eye movements to calculate VOR gain.
- Test-retest reliability was assessed in 20 participants.
Main Results:
- All participants successfully completed AVRS-guided exercises.
- Mean VOR gain approximated physiologic norms (~-1.0) across sessions.
- Moderate test-retest reliability was observed (ICC: 0.59).
Conclusions:
- The AVRS is a feasible and reliable tool for measuring VOR gain in healthy adults.
- AVRS shows potential as a scalable and accessible platform for VRT delivery.
- Normative data from AVRS can guide VRT progression in clinical settings.

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
