An Analysis of the Reliability and Validity of a Korean Version of the Mobility and Gait Assessment Tools for Patients with Stroke

ABSTRACT

PURPOSE: This study aimed to systematically analyze the reliability and validity of Korean versions of mobility and gait assessment tools for patients with stroke. METHODS: Two reviewers conducted an independent literature search and systematically reviewed the literature. Literature published until June of 2017 was searched using search engines for electronic databases. The 2 reviewers reviewed the title and abstract of each article. Among the articles examined, we read the full text of those judged to be suitable for our study. We classified the selected data into research methods and results. The determination was made through mutual agreement. RESULTS: The reviewers selected 5 articles related to the purpose of this study. The DGI was found to be moderately associated with BBS, 10MWT, and TUG in intra-rater reliability (ICC=0.92), inter-rater reliability (ICC=0.88), and concurrent validity tests. The FGA demonstrated a high level of reliability with intra-rater (ICC=0.92–0.95) and inter-rater reliability (ICC=0.91, 0.95). The intra-rater reliability of the RMI was high at ICC=0.98. Its concurrent validity showed a high association with STREAM and BI. The intra-rater reliability of the MAS was ICC=0.75–0.99. Its inter-rater reliability was very high, exceeding 0.99. The inter-rater reliability of the Tinetti-gait Scale was ICC=0.91, and its concurrent validity was moderately associated with the DGI, 10WMT, OLST, FM-L/E, and STS. CONCLUSION: The results of this study revealed that the reliability and validity of the Korean versions of the mobility and gait assessment tools were high.
