Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Background:

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo requiring expert diagnosis.
Current diagnosis relies on physician observation of nystagmus and vertigo during positional changes.

Purpose of the Study:

To integrate eye movement video and head position data for BPPV diagnosis.
To apply artificial intelligence (AI) methods to enhance BPPV diagnostic accuracy.

Main Methods:

Developed a BPPV dataset from 518 patients (Jan-Mar 2021).
Proposed a multimodal deep learning model combining video understanding, self-encoder, and cross-attention mechanisms.

Main Results:

The model achieved an average accuracy of 81.7% on the test set.
Demonstrated the effectiveness of combining head position and eye movement information.
Highlighted the critical role of postural and oculomotor data in diagnosis.

Conclusions:

AI-based methods show potential for improving BPPV diagnostic accuracy.
Integrating postural and oculomotor information is crucial for effective BPPV diagnosis.
