Abstract
Background/aims The purpose of this study was to examine the intra-rater reliability of the Gait Real-time Analysis Interactive Laboratory system during self-paced mode, in repeated gait analysis of healthy individuals. Methods A total of 10 healthy men (age: 35.4 ± 13.3 years; body mass index: 25.2 ± 4.3) and 10 healthy women (age: 41.1 ± 16.4 years; body mass index: 24.5 ± 2.6) were split into two groups according to sex. They walked on a split-belt, self-paced treadmill. Each participant completed two gait assessments separated by an average of 7 ± 3 days. Key gait kinematic, kinetic and spatial-temporal parameters were analysed. The interclass correlation coefficient, standard error of measurement and minimum detectable change were calculated to evaluate the reliability of these gait parameters. Results There was a high repeatability of spatial temporal and excellent repeatability of kinematic and kinetic parameters in both groups. Conclusions The findings suggest that the Gait Real-time Analysis Interactive Laboratory system in self-paced mode is a good instrument to evaluate gait parameters for women as well as men.
