[Applications and uses of static and dynamic measurement of posture (posturography)]

Posturography is a very useful clinical instrument to quantify, analyze, and document postural sway and to differentiate patterns of instability that are typical for the different types of lesions encountered within the cerebellum and to differentiate cerebellar ataxia from spinal ataxia. An objective method of measurement like this is most valuable for follow-up studies and the surveillance of therapeutic efficacy. The method of recording short, medium, and long latency reflexes in leg muscles after a sudden tilt of a movable platform toe-up is not only totally atraumatic and fast, but more importantly it gives significant hints towards the possible site of a central lesion in the sensory-motor system.
