Abstract
[Purpose] In this study, we investigated the intra-rater and the inter-rater reliability of the tandem gait test. [Subjests and Methods]: Fifty-seven adult people (49 females and 8 males, 66.2 ± 8.3 years) were assessed twice by two assessors who had different clinical experience. The participants were instructed to walk heel to toe on a line of 50 mm width, red tape. We measured the three different values by tandem gait tests using the time of 5 m tandem gait and the number of mis-step(s). Intra- and inter -rather reliability were tested with the Intraclass Correlation Coefficient (ICC) and Bland-Altman analysis. [Results and Conclusion] The tandem gait tests can guarantee high reliability under a specific measurement condition, such as two or more repetitive measurements, and depend on the clinical experience of the assessor.
