CCD video camera system in the assessment of balance function Ye Shuangying / 中华老年医学杂志

ABSTRACT

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 indexesTrunks,ayAngle (TSS Trunk Sway Speed(TSS) and fall index (FI).the normal groupFI≥I; mild group0.7≤FI＜I; moderate group0.4≤FI＜0.7; severe groupFI ＜0.4.Disorder of balance function group42 patients with cerebrovascular accident,mean age of (67.4±8.0) years.Control group42 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.
