Seamless integration of visual, vestibular, and somatosensory (VVS) systems is key to human movement control. Emerging evidence suggests autonomic nervous system (ANS) function may influence this integration, yet no studies have examined the relationship between ANS activity, indexed by the pupil light reflex, and VVS function....
No actionable change — findings are correlational and do not yet provide validated tools or cut-offs for clinical vestibular or balance assessment.
If autonomic nervous system measures reliably predict sensorimotor integration, they could become useful adjuncts in vestibular and balance disorder workups, broadening the audiologist/vestibular specialist's assessment toolkit.
- 01Study investigated correlations between autonomic nervous system (ANS) function and sensorimotor (movement control) performance.
- 02Sensorimotor integration involves visual, vestibular, and somatosensory (body-position sense) inputs.
- 03Correlational study design limits causal inference.
- 04Relevance to audiology lies in vestibular assessment and balance rehabilitation.
- 05Results may inform future multimodal assessment protocols but require replication before clinical use.
Measures of autonomic nervous system function correlate with sensorimotor performance including vestibular and somatosensory integration.
