摘　　要：目的 分析使用CCD摄像仪检测系统测定老年人平衡能力的敏感性,从而探讨其测定人体平衡功能的可能性. 方法 采用CCD摄像仪检测系统由CCD摄像仪.观察指标主要有：身体动摇角度（TSA）、身体动摇速度（TSS）和跌倒指数（FI）.根据FI分为对照组和平衡功能障碍轻度、中度、重度组.平衡功能障碍组为丽水市第二人民医院老年科收治的脑血管意外患者42例,平均年龄（67.4±8.0）岁.对照组为健康体检志愿者42例,平均年龄（65.3±6.5）岁.所有参与者均Berg平衡量表评分,CCD摄像仪的测定TSA、TSS、FI,使用CCD摄像仪每人开眼（eo）检测3次,闭眼（ec）检测3次,取平均值. 结果 平衡功能障碍组与对照组相比,TSAeo、TSAec、TSSeo、TSSec、FIeo、FIec差异有统计学意义（P＜0.01）;Berg平衡量表评分差异有统计学意义（P＜0.05）.平衡功能障碍组中TSAeo、TSAec、TSSeo、TSSec轻度、中度、重度间均差异有统计学意义（P＜0.05）,重度与轻度间TSAeo、TSAec、TSSeo、TSSec有显著（P＜0.01）.Berg平衡量表评分重度与轻度间有差异（P＜0.05）. 结论 测定人体平衡功能CCD摄像仪检测系统敏感性较高,较Berg平衡量表CCD摄像仪具有更高的敏感度,值得临床推广.Objective To probe into possibilities and sensitivity of CCD video camera system in the assessment of balance function.Methods The system is composed of a CCD video camera,a video image capture board and analysis software.Three indexes：Trunks,ayAngle （TSS Trunk Sway Speed（TSS） and fall index （FI）.the normal group：FI≥I; mild group：0.7≤FI＜I; moderate group：0.4≤FI＜0.7; severe group：FI ＜0.4.Disorder of balance function group：42 patients with cerebrovascular accident,mean age of （67.4±8.0） years.Control group：42 healthy subjects,mean age of （65.3±6.5） years.All cases were measured by Berg balance scale and determinated three times by CCD video camera system with eye opening （eo） and eye closing（ec）,and averaged.Results There were very significant differences in TSAeo,TSAec,TSSeo,TSSec,FIeo,FIec between disorder of balance function group and control group （P＜0.01）.as well as Berg balance scale （P＜0.05）.In disorder of balance function group,the differences among three groups were significant in TSAeo,TSAec,TSSeo,TSSec （P＜0.05）.There were significant differences in TSAeo,TSAec,TSSeo,TSSec between severe group and mild group （P＜0.01） as well as in Berg balance scale （P＜0.05）.Conclusions CCD video camera system has a higher sensitivity in assessment of body,balance than Berg balance sca land great value in clinical application.
