Computerized dynamic posturography (CDP), also called test of balance (TOB), is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of posture and balance, both in normal (such as in physical education and sports training) and abnormal conditions (particularly in the diagnosis of balance disorders and in physical therapy and postural re-education). Due to the complex interactions among sensory, motor, and central processes involved in posture and balance, CDP requires different protocols in order to differentiate among the many defects and impairments which may affect the patient's posture control system. Thus, CDP challenges it by using several combinations of visual and support surface stimuli and parameters.
Posturography for the Clinician

The value of posturography to the musculoskeletal clinician is that it enables us to measure movement in a vertical plane, or indeed any movement that can be translated into a vertical plane. This means that we can use standardised objective testing to quantify and document what we do. In addition we can test and measure function in ways that we couldn’t do previously, and we can do all this quickly, and see the results in real time.

I have laid out in Specific Movement and Balance Testing the testing that I do. For further information and how to apply posturography clinically for evaluation and rehabilitation, please subscribe to my blog.

I am currently writing a Posturography training program for Physical Therapists. If you would like to learn how to incorporate Posturographic testing and rehabilitation in your practice register your interest by contacting me.

Inner Ear Pathology

Posturography is a non specific test of balance. It can quantify stability and document the characteristics of instability, however it is not a diagnostic tool for specific pathology. Patients with suspected vestibular pathology should be considered for MRI, VEMP’s (Vestibular Evoked Myogenic Potentials) and Caloric testing, which test the saccule and lateral canals respectively.
