Description

This presentation focuses on the clinical relevance of saccadometry in the assessment of vestibular balance and central compensation mechanisms. By analyzing saccadic eye movement parameters such as latency, velocity, and accuracy, the talk highlights how saccadometry reflects central processes involved in balance control, spatial orientation, and adaptive strategies in patients with dizziness and imbalance. Emphasis is placed on the added clinical value of saccadic measures beyond conventional reflex-based vestibular tests.

Outcome Objectives

At the end of this presentation, participants will be able to:

1.     Describe the role of saccadic eye movements in balance control and vestibular compensation.

2.     Interpret saccadometric findings in relation to central adaptive and maladaptive mechanisms.

3.     Recognize clinical situations in which saccadometry complements standard vestibular balance assessment.

Background

Balance function depends not only on peripheral vestibular input but also on central integration, prediction, and motor planning. Patients with dizziness or imbalance frequently report persistent symptoms despite normal or compensated peripheral vestibular findings. Saccadic eye movements are generated by distributed cortical and subcortical networks that are closely linked to spatial orientation and balance regulation. Saccadometry provides clinically meaningful insight into these central mechanisms and supports a more comprehensive interpretation of vestibular balance complaints.

Description

This presentation focuses on the role of hearing aids within a multisensory clinical framework, emphasizing how auditory input interacts with vestibular and oculomotor systems to support spatial orientation and balance. Using a Bayesian perspective, the talk highlights how improved auditory signal reliability through amplification can influence central sensory integration, visual stabilization, and postural control. The aim is to provide clinicians with a broader understanding of hearing aid benefits beyond speech perception.

Outcome Objectives

At the end of this presentation, participants will be able to:

1. Explain how hearing aid–mediated auditory input contributes to multisensory integration involved in balance and spatial orientation.

2. Describe the concept of sensory reweighting and its relevance to hearing aid fitting in patients with imbalance or dizziness.

3. Incorporate multisensory considerations into hearing aid evaluation and counseling to optimize functional outcomes.

Background

Hearing aid outcomes are traditionally evaluated based on speech understanding and communication performance. However, auditory signals also play a critical role in multisensory networks that integrate vestibular and oculomotor information. In individuals with hearing loss, reduced auditory reliability may lead to maladaptive sensory reweighting, increasing reliance on visual or vestibular cues and contributing to instability and higher cognitive load. Restoring auditory input through hearing aids may support more efficient multisensory integration and improve functional stability, particularly in older adults and patients with coexisting audiovestibular complaints. This perspective supports a more comprehensive approach to hearing aid assessment and clinical decision-making.
