Key result
Low sensory thresholds were associated with a resting state of sympathetic hyperarousal in males (d=0.86) and greater autonomic reactivity to a coldpressor stressor in females.
Why the study?
Autonomic nervous system functioning is theorised to underpin sensory processing differences, but most studies have measured only sympathetic or parasympathetic activity rather than their balance.
Are sensory processing patterns related to autonomic balance at rest and in response to a sensory-based stressor in young adults?
Cross-Sectional (n=100)
No

Standardized Mean Difference: 0.86
Absolute Event Rate: -0.52% vs 0.6%
p-value: p=0.02
Sensory processing patterns are linked to distinct patterns of autonomic balance, with young men having low sensory thresholds exhibiting a resting state of sympathetic hyperarousal.

Hypothesis-generating for autonomic-sensory links in young adults; leaves open causality and clinical utility pending longitudinal data.
Kerley et al. (2022) conducted a cross-sectional in Sensory processing patterns (n=100). Low sensory threshold vs. Typical or high sensory threshold was evaluated on Baseline cardiac autonomic balance (CAB) in males (d 0.86, p=0.02). Low sensory thresholds were associated with a resting state of sympathetic hyperarousal in males (d=0.86) and greater autonomic reactivity to a coldpressor stressor in females.
