The purpose of this study was to examine the accuracy and reproducibility of intracranial pressure (ICP) measured by the external ventricular drainage (EVD) system. The effect of specific gravity (SpGr) of cerebral spinal fluid (CSF) on the accuracy of the EVD-measured-ICP was also determined. Sixty-two subjects with EVD system were included. The ventriculostomy catheter connected to both the ICP monitor and EVD system was used to measure ICP. ICP was repeatedly measured 6 times in three positions: head at 0 degree, head up 15 degree, and head up 30 degree. The accuracy of the EVD-measured-ICP was determined using the Pearson’s correlation, paired t-test, and the Bland-Altman method. Analysis of the reproducibility of ICP measurements by EVD system was done with the Pearson' correlation and coefficient of variation (CV). The mean ICP between two measurements was significantly correlated (r = .93, p < .001) at head 0 degree position; the bias (mean difference) showed significant differences (p < .001); the standard deviation was 2.0 ± 1.6 mmHg; and the limit of agreement (bias ± 2SD) were between − 1.2 and 5.2 mmHg. Position at head up 15 degree displayed significant correlation (r = .94, p < .001); the bias showed significant differences (p < .001); and the standard deviation was 2.1 ± 1.5 mmHg, with the limits of agreement being − 0.9 and 5.2 mmHg. At head up 30 degree, the correlation between measurements was significant (r = .95, p < .001); the bias had significant difference (p < .001); the standard deviation was 2.0 ± 1.6 mmHg; and the limits of agreement were − 1.2 and 4.9 mmHg. There was no significant correlation between SpGr of CSF and difference of mean ICP by EVD system and monitor measurements (p > .05). The EVD-measured ICP had good reproducibility (p < .001). The CV at head 0 degree was 3.69%, head up 15 degree was 6.62%, and head up 30 degree was 7.88%. In conclusion, the agreement of ICP measurements between the EVD system and monitor was poor and th

背景与目的:本研究目的为验证台湾版特定活动平衡信心量表(Chinese version of the Activities-specific Balance Confidence scale)应用於中风患者之再测信度。方法:本研究徵召13位居住於社区且能独立行走之慢性中风患者,每位患者都会接受由同一位物理治疗师所施测之台湾版特定活动平衡信心量表,前後共两次。研究者使用Cronbach's α检验量表的内在一致性,并且利用级内相关系数(intraclass correlation coefficient, ICC)验证再测结果之信度。结果:台湾版特定活动平衡信心量表具有很高的内在一致性(Cronbach's α=0.96),且级内相关系数高达0.94(95%信赖区间为0.83-0.98),表示有相当良好的再测信度。结论:本研究显示台湾版特定活动平衡信心量表有高度的内在一致性和良好的再测信度,可提供临床治疗师和研究人员一个符合台湾地区中风患者族群使用的评估工具,可应用於量测中风患者执行日常生活时自我平衡的信心程度。

研究目的:本研究目的为验证中风复健动作评估量表(Stroke Rehabilitation Assessment of Movement , STREAM)之再测信度。研究方法:研究者徵召50名复健科门诊慢性期中风病人,接受治疗师於前後问隔一周共2次的STREAM测量。研究者利用组内相关系数(intra-class correlation coefficient, ICC)验证再测结果之一致性。再依据ICC计算测量标准误(standard error of measurement, SEM)及最小真正改变量(smallest real difference SRD),以利临床及研究人员解释个别病患或群体病患动作能力恢复是否超过测量误差。研究结果:STREAM再测信度ICC值高达0.989(95%信赖区闲为0.981~0.994),显示2次测量结果之一致性良好。STREAM总分之SEM数值代表受试群体改变值(within-group change)是否具备真实变化(或超过测量误差)之阈值为2.00。STREAM总分之SRD数值代表单一个案改变值(within-individual change)是否为真正改变之阈值为5.54。结论:本研究结果证实STREAM具有良好的再测信度与测量误差,临床治疗师和研究人员可根据STREAM之SEM及SRD数值判断中风病人之动作功能进步量是否超过测量误差。
