Objective: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. Methods: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. Results: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 （P<0.01）. The visual scores in the T2DM group were lower than those of the PV group（P<0.01） in the anteroposterior and lateral directions. Conclusion: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.
目的：通过动静态姿势描记仪对2型糖尿病和外周性眩晕患者进行直立姿势稳定性测试，分析其利用感觉结构维持平衡的差异。 方法：研究对象分为对照组（52例）、糖尿病组（45例）和眩晕组（47例），所有受试者均进行6种条件下的直立姿势稳定性测试和感觉结构分析。 结果：糖尿病组在条件1（睁眼、硬平板）、条件4（睁眼、泡沫板）、条件6（视觉干扰、泡沫板）的身体压力中心晃动的姿势包络面积较眩晕组大，差异有统计学意义（P<0.01）。通过感觉结构分析发现，在前后方向和侧方，糖尿病组的视觉评分较眩晕组低，差异有统计学意义（P<0.01）。 结论：2型糖尿病患者和外周性眩晕患者保持直立姿势平衡能力下降，其中2型糖尿病患者利用视觉维持平衡的能力比外周性眩晕患者更差。.
