Dynamic Posturography

Abstract

The arrival of a patient with imbalance can often lead to a silent groan from the treating otolaryngologist. Often it is easy to conclude the clinic visit with “your imbalance is multifactorial” without precisely identifying the contributing factors. Computerized dynamic posturography (CPD) attempts to replicate real-life balance disturbances in an effort to objectively identify potential causes of imbalance. Testing specifically identifies weakness in somatosensory input, visual input, vestibular input, and overall compensation to give a complete picture of a patient’s control of posture. This chapter aims to provide an overview of the techniques and findings of CPD.
