Dynamic Posturography in the Assessment of Balance


Dynamic posturography (i.e., computerized dynamic posturography) tests balance control in situations intended to isolate the factors that affect balance in everyday experiences. Posturography (e.g. NeuroCom EquiTest®) proposes to provide quantitative information on the degree of imbalance present in an individual but does not diagnose specific types of balance disorders.

The individual wears a harness to prevent falls and stands on an enclosed platform surrounded by a visual field. By altering the angle of the platform or shifting the visual field, the test is intended to assess movement coordination and the sensory organization of visual, somatosensory, and vestibular information relevant to postural control. The individual undergoes six different testing situations designed to evaluate the vestibular, visual, and proprioceptive/somatosensory components of balance. In general terms, the test measures an individual’s balance while visual and somatosensory cues are altered.




Randomized controlled studies are lacking for this technology. In addition, the existing studies fail to demonstrate clinical utility of this test that would lead to changes in management that improve outcomes. Therefore, dynamic posturography in the assessment of balance is considered investigational.
