摘　　要：目的　制定一种对颈椎病患者的症状、体征和功能状态进行临床评估的临床评价量表(CASCS) ,并探讨其在颈椎病临床评价中的信度及效度。方法　对 92例颈椎病患者 (实验组 )应用CASCS与Vernon颈椎残障指数量表 (NDI)进行信度、效度和敏感度分析 ,同时应用CASCS对 2 0例正常人 (对照组 )进行评测。并对颈椎病患者康复治疗前、后的CASCS评测结果进行对比分析。结果　CASCS总积分与各条目积分间的组内相关系数 (ICC)为 0 .78～ 0 .99,信度系数Cronbachα为 0 .84。该量表与NDI有较好的相关性(r =0 .76,P <0 .0 1)。康复治疗前 ,颈椎病患者与正常人的CASCS评价结果间有极显著性差异 (t =14 .76,P <0 .0 1)。颈椎病患者康复治疗前、后的CASCS评测结果间有极显著性差异 (t =2 1.0 3,P <0 .0 1)。结论　CASCS具有较高的信度、效度和敏感度 ,是临床评价颈椎病的一种客观。Objective To investigate the reliability and validity of a clinical assessment scale for cervical spondylosis (CASCS) developed by the authors which can objectively evaluate the symptoms, signs and functional status of the patients. Methods A total of 92 cervical spondylosis patients were measured by CASCS and neck disability index (NDI), 20 healthy volunteers were measured by CASCS only. For reliability test, intraclass correlation coefficients (ICC)and Cronbach α coefficient were studied. For validity, the correlation coefficient between CASCS and NDI was analyzed, and the results obtained by use of CASCS in the patients and normal volunteers before physiotherapy were compared. For responsiveness, the results with CASCS in the patients before and after physiotherapy were analyzed. Results ICC of the total scores and each item scores of CASCS was 0.78～0.99, Cronbach α coefficient was 0.84.CASCS had a positive correlation with NDI ( r =0.76, P <0.01). There was a very significant difference between the results of CASCS obtained from the patients and the healthy volunteers ( t =14.76, P <0.01). The results of CASCS obtained from the patients before and after physiotherapy were significantly different ( t =21.03, P <0.01). The size effect was 1.08. Conclusion The CASCS demonstrated very good reliability, validity and responsiveness. It provided an objective and useful instrument in the clinical evaluation of patients with cervical spondylosis.
