Binocular Vergence Testing With Posture Cues for Vertigo Rehab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with vertigo exhibit poor binocular motor coordination and postural control, with vergence errors and vestibular dysfunction contributing to their symptoms, necessitating a new clinical management approach that considers the symbiotic interaction between vergence and vestibular function.
Innovation Solution
A method using the REMOBI device to perform vergence and saccade tests in seated and standing positions, combined with posture tests, to measure and improve binocular motor coordination and postural parameters through targeted stimulation with visual or audiovisual targets in real space, followed by rehabilitation sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional vergence tests are performed in a single position (seated or standing), then the test protocol is simple, but the measurement precision of binocular motor coordination is insufficient
Solution Approach 1:
The test protocol is segmented into multiple independent components: seated vergence tests, standing vergence tests, and posture tests. Each component can be administered separately and contributes specific measurement data, allowing comprehensive assessment while maintaining modular simplicity in each individual test segment.
Solution Approach 2:
The assessment transitions from a single-dimensional seated position to multi-dimensional evaluation by adding standing position and postural parameters. This dimensional expansion captures the interaction between vergence and vestibular systems that single-position tests miss, improving measurement precision without requiring complex equipment.
2Reliability
If vergence tests are performed without considering postural position, then the test procedure is simple, but the reliability of diagnosing vertigo-related vergence disorders is reduced
Solution Approach 1:
Vergence testing and postural assessment are merged into a unified protocol where both seated and standing vergence tests are administered with simultaneous postural measurements. This combination captures the symbiotic interaction between vergence and vestibular function, improving diagnostic reliability while maintaining procedural straightforwardness.
Solution Approach 2:
Postural parameters serve as feedback indicators that reveal how vestibular dysfunction affects vergence performance. By comparing vergence metrics across different postural positions, clinicians can identify position-dependent vergence disorders with higher reliability, and the protocol remains easy to administer through systematic data collection.
3Adaptability or versatility
If traditional ocular motor assessment is used without addressing postural control, then the assessment scope is narrow but the evaluation process is simple, but it fails to capture the symbiotic interaction between vergence and vestibular function
Solution Approach 1:
The assessment protocol achieves multi-functionality by simultaneously evaluating vergence performance, saccade accuracy, and postural control within a unified framework. This universal approach captures the symbiotic interaction between oculomotor and vestibular systems without requiring separate specialized tests, making the protocol versatile yet manageable.

AI summary
The present invention relates to a method for measuring binocular motricity parameters and postural parameters in ecologic conditions (both eye viewing targets displaced in the real 3D space) for individuals suffering from vertigo comprising at least two REMOBI tests of eye movements and a posture test, wherein the REMOBI tests are performed using a device physically stimulating vergences or saccades in the real world in three dimensions and contain multiple trials for each type of stimulation, vergences or saccades. The REMOBI eye movement tests are performed once with the individual in seated position and the other time with the individual in standing position. In the latter case, posture is measured simultaneously. It further relates to a method for detecting intrinsic binocular motor abnormalities and/or postural control abnormalities in an individual suffering from vertigo using the same vergence and posture tests. It also relates to a method for improving binocular motor coordination and postural control in an individual suffering from vertigo.
