可穿戴式平衡诊疗系统评估前庭性眩晕患者动静态平衡功能的初步观察

Preliminary observation of wearable balance diagnosis and treatment system in evaluating dynamic and static balance function in patients with vestibular vertigo

该研究通过研发的可穿戴式平衡诊疗系统测试,初步探讨可反映前庭性眩晕患者异常平衡功能状态的评估指标。该研究为横断面研究,选取2022年7月至2023年5月复旦大学附属眼耳鼻喉科医院门诊诊断为非急性期前庭性眩晕的30例患者为眩晕组,男13例,女17例,年龄(45.7±13.9)岁;同期选取20名健康人为健康对照组,男8名,女12名,年龄(43.6±8.0)岁。采用由复旦大学附属眼耳鼻喉科医院牵头研发的可穿戴式平衡诊疗系统测试并分析两组静态平衡和稳定极限试验(LOS)结果。在静态平衡测试中,眩晕组睁眼有软垫/睁眼无软垫的比值小于健康对照组[1.20%(0.92%,1.53%)比1.49%(1.22%,1.81%),P=0.008]。在LOS中,眩晕组8个方向的方向控制力,以及正前、正后、右前、右后的最大偏移,正后、右后、左后的端点行程均小于健康对照组,左后方向的反应时间长于健康对照组(均P<0.05)。本研究结果提示LOS的方向控制力、最大偏移、端点行程可考虑作为动态平衡功能评估的重要参考指标。

A newly developed wearable balance diagnosis and treatment system was studied to evaluate the indexes of the abnormal balance function in patients with vestibular vertigo.A cross-sectional study was carried out.A total of 30 patients diagnosed with non-acute vestibular vertigo in the outpatient department of Eye,Ear,Nose and Throat Hospital Affiliated to Fudan University from July 2022 to May 2023 were selected as the vertigo group,including 13 males and 17 females,and aged(45.7±13.9)years.Meanwhile,20 healthy controls(8 males and 12 females)were included as the control group,with a mean age of(43.6±8.0)years.The static balance and limits of stability(LOS)function of all subjects were assessed with wearable balance diagnosis and treatment system developed under the leadership of Eye&ENT Hospital of Fudan University.In the static balance test,the ratio of eyes open with cushions to eyes open without cushions in the vertigo group was less than that of the control group[1.20%(0.92%,1.53%)vs 1.49%(1.22%,1.81%),P=0.008],indicating that patients with non-acute vestibular vertigo may compensate static balance ability earlier.In vertigo group,the directional control in 8 directions,the maximum excursion in anterior,posterior,right anterior and right posterior directions,the endpoint excursion in the posterior,right posterior,and left posterior directions were all smaller than those of the control group(all P<0.05).The reaction time in the left posterior direction of vertigo group was longer than that of the control group(all P<0.05).Those results indicated that the directional control,maximum excursion and endpoint excursion of LOS could be considered as important reference indexes for dynamic balance function.
