[Sensory organization test results for maintaining an upright balance in patients with type 2 diabetes mellitus and patients with peripheral vestibular disorders].

To research the differences of sensory organization testing in maintaining postural stability between patients with type 2 diabetes mellitus and patients with peripheral vertigo using computerized posturography. Participants were divided into the control group （52 cases）, the type 2 diabetes mellitus group （T2DM） （45 cases）, and the peripheral vertigo group （PV） （47 cases）. All participants were examined under six conditions by computerized posturography: The sensory organization test, a part of computerized dynamic posturography, was used to assess the abilities of vision, somatosensory and vestibular systems in maintaining postural stability. The scores of statokinesiogram （SKG） of the T2DM group in condition 1 （standing on static platform with eye open）, condition 4（standing on foam platform with eyes open） and condition 6（standing on foam platform with servo-controlled vision） were significantly greater than that in the vertigo group （<0.01）. The visual scores in the T2DM group were lower than those of the PV group（<0.01） in the anteroposterior and lateral directions. Patients with type 2 diabetes and peripheral vertigo have a decreased ability to maintain balance in the upright position. Patients with type 2 diabetes have a poorer ability to maintain balance with visual systems than patients with peripheral vertigo.
