Oswestry功能障碍指数评定腰痛患者的可信性

Reliability of the Modified Oswestry Disability Index for evaluating patients with low back pain

目的 :探讨Oswestry功能障碍指数 (OswestrydisabilityIndex ,ODI)应用于腰痛患者评定的可信性。 方法 :住院拟手术的腰痛患者 2 2例 (男 13,女 9例 ) ,分为同一检查者重复评定 (A组 ) :10例 ,平均年龄 4 7 7岁 ;不同检查者重复评定 (B组 ) ,12例 ,平均年龄 36 6岁。用ODI对所有对象重复评定 ,平均间隔 3 0d。对两组患者的障碍指数进行Pearson相关分析。结果 :两组重复测试ODI的相关系数分别为 0 95 3和 0 912 ,相关性非常显著 (A组 :t =8 85 1,P <0 0 0 1;B组 :t=7 0 0 8,P <0 .0 1)。结论 :用ODI评定腰痛是稳定、可靠的 ,可作为腰痛患者是否需要手术或康复疗效评定的参考指标。

Objective:To determined the reliability of the Oswestry Disability Index(ODI) for evaluating patients with low back pain.Method:22(female 9,male 13) subjects who were inpatients of the orthopedic words were evaluated using the modified ODI in Chinese before operation.They were divided into two groups:intrarater reliability group(n=10) and interrater reliability group(n=12).The patients answered the ODI.The test retest reliability was done in every 3 days and compared using a Pearson Correlation,individually.Result:The highly correlated coefficient of 0 953( t=8 851,P <0 001) and 0 912( t=7 008,P <0 01)were obtained in intrarater reliability group and interrater reliability group individually.Conclusion:The modified ODI in Chinese shows the superior reliability.This assessment method allows the evaluation of multiple parameters of the patient′s function. It can be used to study the clinical outcome of postoperation or rehabilitation in patients with low back pain.
