Which sense is consistently accurate across CTSIB conditions 4, 5, and 6?

Explanation:
In these challenging CTSIB conditions, the body must rely on information about head movement and orientation relative to gravity rather than what is seen or felt through the feet. Vision is either removed or made unreliable, and the support surface somatosensation is degraded. That leaves the vestibular system as the consistent source of spatial orientation. It detects head motion and equilibrium cues independent of eye input or surface feedback, so it remains accurate across these conditions. The other senses become unreliable or unavailable, which is why vestibular information stands out as the consistent contributor to balance in these scenarios.
