【摘要】:目的 :改良Oswestry功能障礙指數(shù)(Oswestry disability index,ODI)量表評價體系,評估其臨床信度和效度。方法:采用包含多種評價指標的隨訪表對100例手術患者進行術前及術后3個月隨訪,根據(jù)隨訪結果,剔除依從性差的評價項目,篩選出適合國人的、能反映術后短期腰部功能改善情況的指標,將"生活自理"、"提重物"、"性生活"、"社會生活"、"旅游"5個評定項目換為"下肢麻木程度"、"臥位翻身"、"坐位站起"、"家務勞動"、"工作情況"5個評定項目,建立改良版ODI量表。采用JOA腰痛評分(Japanese Orthopaedic Association low back pain score)、ODI及改良版ODI量表對41例行手術治療的患者進行隨訪評定,其中22例行微創(chuàng)椎間盤手術,19例行開放椎間盤手術。評定時間點為術前及術后1周、2周、4周、8周、12周、24周,以內部一致性、分半信度為指標評估量表的信度,以因子分析、Pearson相關系數(shù)評價量表的結構效度和內容效度。結果:改良版ODI量表總的Cronbach′sα系數(shù)為0.849,各項目的 Cronbach′sα系數(shù)均在0.813~0.861之間,分半信度系數(shù)為0.894;因子分析的檢驗結果顯示,KMO值為0.857,Bartlett球形檢驗P0.001。主成分分析提取全部10個因子,累計方差貢獻率為67.2%;內容效度的檢驗結果顯示,改良ODI與JOA、ODI分值顯著相關,相關系數(shù)分別為-0.695(P0.001)、0.819(P0.001)。結論:改良版ODI量表具有良好的信度和效度,適合國人進行腰椎功能評定及手術后短期的療效評定,中長期的評定效果有待進一步驗證。
[Abstract]:Objective: to evaluate the clinical reliability and validity of Oswestry dysfunction index (Oswestry disability index) evaluation system. Methods: 100 patients were followed up preoperatively and 3 months after operation with multiple evaluation indexes. According to the results of follow-up, the items of poor compliance were excluded, and the suitable ones for Chinese were selected. An index that can reflect the improvement of lumbar function in the short term after operation, The five items of "living self-care", "lifting heavy objects", "sexual life", "social life" and "tourism" were changed to "numbness degree of lower extremity", "lying position turn over", "sitting up", "housework work", "work condition", and established the improved ODI scale. JOA low back pain score and modified ODI scale were used to evaluate 41 cases of surgical treatment. 22 cases were treated with minimally invasive disc surgery and 19 cases with open disc surgery. The evaluation time points were pre-operation and postoperation 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks. The reliability of the scale was evaluated by internal consistency and split-half reliability. The structural validity and content validity of the scale were evaluated by factor analysis and Pearson correlation coefficient. Results: the total Cronbach's 偽 coefficient of modified ODI scale was 0.849, the Cronbach's 偽 coefficient of each item was between 0.813 and 0.861, and the split-half reliability coefficient was 0.894.The result of factor analysis showed that the total Cronbach's 偽 coefficient was 0.849, the Cronbach's 偽 coefficient of each item was between 0.813 and 0.861, and the factor analysis showed that the Cronbach's 偽 coefficient was 0.857Bartlett spherical test (P0.001). All 10 factors were extracted by principal component analysis (PCA), and the cumulative contribution rate of variance was 67.2%. The results of content validity test showed that there was a significant correlation between the scores of modified ODI and JOAA ODI, and the correlation coefficients were -0.695g P 0.001C 0.819g P0.001g. Conclusion: the modified version of ODI scale has good reliability and validity, which is suitable for the evaluation of lumbar spine function and the short-term curative effect after operation, and the medium and long term evaluation results need to be further verified.
