During Computerized Dynamic Posturography, the person stands on a computerized platform while balance is measured under different circumstances. For example, the floor may move beneath the person’s feet, or the patient may be asked to maintain balance with eyes closed (see below for the four parts of the assessment). The reflex movements made by the person to keep from falling are measured and this helps determine which part of the balance system is affected. Increased postural sway is a strong indicator of poor balance and a leading cause of falls. The results of this test may help the neurologist determine the cause of the balance – visual, vestibular, or proprioceptive.
