简要总结
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.
详细描述
Proprioception plays a well-established role in postural control and motor coordination, but increasing evidence supports its involvement in higher-level sensory processing, including spatial localization and multisensory integration. Given the anatomical overlap of trigeminal afferents innervating both oculomotor and orofacial structures, this study focused on the potential interplay between the stomatognathic and visual systems.
This study is an observational investigation with an experimental within-subject design with repeated measures in healthy volunteers.
The aim is to investigate the influence of oral proprioceptive stimuli on visual perception and audiovisual integration in healthy young adults, and explore whether non-invasive oral stimuli could modulate the occurrence of transient visual distortions-specifically Visual pseudo-Scotomas (VS)-when binocular vision is altered, and whether these stimuli could counteract the effects induced by auditory input.
Participants have been screened to ensure normal hearing, vision, and dental status, and underwent testing using the Vertical Maddox Test, which induces a dissociation in binocular vision that relies heavily on proprioceptive cues.
The experimental protocol was composed of four phases:

结局指标
主要结局
Presence of Visual Pseudo-Scotomas (VS) under Auditory and/or Oral Proprioceptive Stimulation
时间窗: During 4-phase experimental protocol (single visit, approx. 45 minutes)
Participants were assessed for the occurrence of functional visual disturbances (pseudo-scotomas, or VS) during each phase of the protocol using the Vertical Maddox Test. Presence or absence of VS was recorded under three experimental conditions: auditory stimulation alone, combined auditory and oral proprioceptive stimulation, and oral proprioceptive stimulation alone.
次要结局
- Elimination of Sound-Induced Visual Pseudo-Scotomas by Oral Proprioceptive Stimuli(Day 1, during phase 3 (auditory + OPS) of the experimental protocol)
- Presence of Visual Pseudo-Scotomas with Oral Proprioceptive Stimulation Alone(Day 1, during phase 4 (OPS alone) of the experimental protocol)
