Examination of the reliability of Gait Assessment and Intervention Tool in patients with a stroke
本研究检验了步态评估与干预工具（GAIT）在15名脑卒中患者中的信度，发现评估者间信度良好，最小可检测变化为7.68分，表明该工具可用于临床步态评估。
The Gait Assessment and Intervention Tool (GAIT) has been recently developed for gait assessment in patients with stroke, and it is considered as a tool that may identify clinically relevant deviations from normal gait and quantifies relevant changes in gait because of an intervention. The objective was to analyze the GAIT psychometric properties in participants with stroke. A convenience sample of 15 adults with stroke was selected (58.15±7.8 years; 5.38±3.3 years from injury). We used the GAIT for evaluating the gait in patients with stroke. GAIT scoring is based on observations of anterior/posterior and lateral-view video documents. Inter-rater reliability of the GAIT between trained raters was good (intraclass correlation coefficient=0.762; P=0.008; 95% confidence interval=0.749-0.926). The minimal detectable change was 7.68 points (12.39%). Inter-rater reliability for the hip, knee, and ankle items was also good. In conclusion, the current study demonstrated that GAIT has good inter-rater reliability and good internal consistency.
