This study introduces a novel device to measure the tactile/somatosensory system's role in subjective vertical perception, aiding otoneurology research into macular and otolithic pathways.

Area of Science:

Otoneurology
Neuroscience
Biomedical Engineering

Background:

Subjective vertical perception is crucial for understanding macular function and central otolithic pathways.
Current devices often assess visual and vestibular contributions, but the somatosensory component requires further investigation.

Purpose of the Study:

To develop and present a new device specifically designed to isolate and assess the tactile/somatosensory subsystem's contribution to subjective vertical perception.
To differentiate the somatosensory input from visual, vestibular, and proprioceptive inputs in verticality assessment.

Main Methods:

A novel handheld device incorporating two orthogonally oriented Micro Electro Mechanical System (MEMS) accelerometers was developed.
The device transmits data to a remote visualization apparatus for analysis.

Patients align the bar vertically based on their perceived verticality, isolating the tactile/somatosensory sense.

Main Results:

The developed instrumentation allows for the specific assessment of the tactile/somatosensory subsystem's role in subjective vertical perception.
This device offers a novel approach compared to existing commercial tools that evaluate other sensory subsystems.

Conclusions:

The new device provides a targeted method for evaluating the somatosensory contribution to subjective verticality.
This advancement can enhance diagnostic capabilities in otoneurology for conditions affecting macular function and central otolithic pathways.
