Department of Rehabilitation Medicine, National Rehabilitation Hospital,Department of Biomedical Engineering, College of Health Science, Yonsei University* Background: Accelerometer is one convenient device that can easily measure human movement and provideboth qualitative and quantitative information about it. The purpose of this study is to find out useful parameters oftrunk accelerometry in evaluating gait abnormalities of stroke patients with hemiparesis by comparing it withother characteristics of hemiparetic gait. Methods: Nine hemiparetic stroke patients were enrolled in the study. Aportable accelerometer was attached between L3,4 intervertebral area, and vertical and medio-lateral accelerationwere measured during 10m walking of each subject. Other gait characteristics such as linear parameters, foot con-tact area and force, center of pressure were measured by F-scan. Results: Swing symmetry showed significantcorrelation with mean value of peak I of unaffected side, standard deviation of step time of unaffected side, steptime ratio and walking velocity. Stance symmetry showed significant correlation with standard deviation of steptime of unaffected side, step time ratio and walking velocity. (p<0.05) Anteroposterior distance of center of pres-sure, maximal force and foot contact area did not show significant correlation with accelerometric parameters.C o n c l u s i o n s: In evaluating gait abnormalities of hemiparetic stroke patients by trunk accelerometry, step timeratio, standard deviation of step time and mean of peak I in unaffected side can be used as useful parameters thatreflect gait symmetry. 대한뇌졸중학회지제6권제1호2 0 0 4년5월
