2型糖尿病和外周性眩晕患者感觉结构分析的异同

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

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。

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(T2 DM)(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 T2 DM 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 T2 DM 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.
