COMPUTERIZED DYNAMIC POSTUROGRAPHY: A BRIEF HISTORY

The technique commonly referred to in the clinical literature as Computerized Dynamic Posturography (CDP) was developed though a series of basic research studies on human movement control, which were funded by the National Institutes of Health and NASA in the 1960's and 1970's. CDP as a clinical tool for evaluating the sensory and motor components of balance control was first described by Nashner, et al¹ in 1982 and the technique became available commercially in 1986 when NeuroCom International, Inc. introduced the EquiTest® system. The specific test protocols consisting of the Sensory Organization Test (SOT), Motor Control and Adaptation Tests (MCT and ADT), which classify a device as CDP, were further described in the 1997 Technology Assessment published in Otolaryngology Head & Neck Surgery.²

CDP, is now considered to be the standard quantitative method for isolating and assessing the sensory and motor components of balance.³
