What Is the Equilibrium Triad?

depend upon the effective development and functioning of three different but interdependent sensory systems (an “Equilibrium Triad”), namely the vision sense, the Vestibular sense, and the combined tactile/ proprioceptive senses.

What is the sensory triad?

The visual, vestibular and somatosensory systems interact together as a “Triad of Equilibrium” to monitor the position of the head and cervical spine. The brain is encased in a durable shell at the top of the axial system, surrounded by powerful sensory receptors.

What are the 3 sensory input systems involved in maintaining the upright posture?

Upright bipedal stance is traditionally described to depend on sensory (vision, vestibular, and somatosensory) input to provide postural equilibrium and a proper alignment of body segments with respect to gravity. The nature of multisensory interactions has been the subject of a plethora of studies.
