目的：建立一种生物力学测试方法，为临床诊断颈性眩晕提供量化依据。
方法：2004年7月至2006年11月，应用人体重心测试系统对86例正常人(男40例，女46例；年龄20～74岁，平均30岁)和75例颈性眩晕患者(男16例，女59例；年龄20～74岁，平均44.5岁)进行定量测试和定性诊断，并用目前颈性眩晕的临床诊断方法(current diagnosical method of cervical vertigo,CDM法)作为对照，进行临床诊断性试验。对静态站立睁、闭眼时重心测试诊断颈性眩晕(static posturography method of cervical vertigo,SPG法)的临床价值进行评价。
结果：闭眼时SPG法诊断颈性眩晕的灵敏度为76%, 特异度为93%,Youden指数为69%, 符合率为85.1%;阳性预测值为90.5%,阴性预测值为93%,阳性似然比为10.893,阴性似然比为0.258.睁眼时SPG法诊断颈性眩晕的灵敏度为49.3%,特异度为87.2%,Youden指数为38.6%, 符合率为69.6%; 阳性预测值为77.1%, 阴性预测值为87.2%, 阳性似然比为3.857, 阴性似然比为0.581.无论睁眼还是闭眼状态，正常人的重心移动轨迹图以前后型为多见，颈性眩晕患者则以弥散型为多见。
结论：闭眼时人体重心测试法能较准确地鉴别颈性眩晕患者与正常者，其真实性、可靠性及临床应用价值较好，已达到客观化、量化诊断颈性眩晕的基本要求。而睁眼状态时的漏诊率较高，难以满足临床诊断要求。 |

Abstract:
Objective: To provide a quantitative base for diagnosing cervical vertigo by establishing a biomechanics method.
Methods: From July 2004 to Nov 2005,the static posturography(SPG) of normal 86 health individuals and 75 patients with cervical vertigo were quantitatively measured and qualitative diagnosis respectively in closed and open eyes. There were 40 male and 46 female in health adults,ranging from 20 to 74 years old(mean 30 years). There were 16 male and 59 female in vertigo patients,ranging from 20 to 74 years old(mean 44.5 years). In contrast to current diagnosis method of patients with cervical vertigo,the clinical value was evaluated.
Results: Under the state of closed eyes,the sensitivity of SPG diagnosing cervical vertigo was 76%;the specificity was 93%;the Youden index was 69%;the coincidence was 85.1%;the positive predictive value was 90.5%;the negative predictive value was 93%;the positive and negative likelihood ratio were 10.893 and 0.258 respectively. Under the state of open eyes,the sensitivity was 49.3%;the specificity was 87.2%;the Youden index was 38.6%;the coincidence was 69.6%;the positive predictive value was 77.1%;the negative predictive value was 87.2%;the positive likelihood ratio was 3.857;the negative one was 0.581. Regardless of closed or open eyes,foreword-backward type shift orbit was the most common pattern in the normal individuals. However,diffuse type shift orbit was the most prominent pattern in the patients with cervical vertigo.
Conclusion: The patients with cervical vertigo and normal individuals can be diagnosed objectively and quantitatively with SPG under the state of closed eyes,which can achieve the basic requirements of diagnosing cervical vertigo with validity,reliability and good clinical application. However,the rate of missed diagnosis with SPG under the state of open eyes is too high to meet the diagnostic needs. |
