The Physiology of Vestibular Input

The Physiology of Vestibular Input — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A comprehensive, research-grounded visual explaining why movement, rocking, and spinning help balance, organize, and alert the nervous system.

This infographic covers:

• Anatomical detail: semicircular canals & otoliths, oculomotor alignment, vestibular nuclei, motor control center
• What's happening: movement changes fluid and calcium crystal position in the inner ear; for many individuals, controlled movement acts as a powerful lever to raise low alertness or calm high agitation
• The signal pathway: head/body moves through space → fluid shifts in the inner ear → vestibular nerve transmits signals to the brainstem → brain integrates balance data with visual and proprioceptive input → arousal levels shift → the nervous system achieves equilibrium
• What it can support: arousal regulation, postural control, visual tracking, emotional grounding, spatial confidence
• Autonomic & neurological regulation: rhythmic linear movement soothes an overstimulated system; rotary/dynamic movement boosts alertness; regulation, not stereotypy — self-directed movement is a precise internal effort to balance arousal
• Dynamic effects & movement types: linear input (calming), rotary input (intense, can rapidly alert or cause overload if unregulated), gravitational insecurity, co-regulation support
• What actually helps: offer safe outlets (swings, rocking chairs, trampolines), respect self-pacing, watch for overload signs, combine with deep pressure, honor self-directed motion
• Grounded in Ayres Sensory Integration (ASI); Lane, Reynolds & Thacker (2010); Schaaf & Mailloux (2015)
