Synonyms and keywords: Loss of balance; imbalance; off balance; unsteadiness

Overview

Disequilibrium refers to an impaired sense or absence of balance or equilibrioception, which primarily occurs during standing or walking usually without any cephalic sensations like headache, nausea and vomiting. It is one among the causes of dizziness[1] and is often accompanied by spatial disorientation.
