Sponsor's own description

The goal of this observational study is to investigate how oral proprioceptive stimuli affect visual perception and auditory-visual integration in healthy young adults. The main questions it aims to answer are: * Can Oral Proprioceptive Stimuli (OPS) induce Visual pseudo-Scotomas (VS) in the absence of other stimuli? * Can Oral Proprioceptive Stimuli (OPS) modulate or eliminate Visual pseudo-Scotomas (VS) induced by auditory stimuli? Researchers evaluated 38 healthy adults (aged 20-29) using the Vertical Maddox Test to detect functional visual alterations under different conditions. The study included four phases: * Baseline assessment with no stimuli. * Assessment with auditory stimuli alone. * Assessment with simultaneous auditory and Oral Proprioceptive Stimuli (OPS), including tongue/lip positions (Combined Oral Stimuli) and dental pressure/traction stimuli (Dental Stimuli). * Assessment with Oral Proprioceptive Stimuli (OPS) alone. Visual pseudo-scotomas were recorded based on participant responses. The study was approved by the local ethics committee and all participants gave informed consent.
