dc.description.abstract Introduction. Information regarding stepping time plays an important role in understanding normal and abnormal human gait. Adjusting the time for stepping during gait is a common strategy individual may demonstrate to maintain gait balance. Therefore, we analyzed the stepping time among eight healthy young individuals during both a simple reaction time task (SRT) and a choice reaction time task (CRT). Purpose. The objective of this study is to investigate if SRT and CRT have different effects on Step Time. A secondary aim of this study is to discuss the importance of using the information regarding step time to improve gait training designed for those with gait impairments in physical rehabilitation programs. Methods. Eight healthy young subjects (18-24 years old) participated in this study. All of the participants (four females, four males) were right-leg dominant. Participants were instructed to stand upright and barefoot on a force platform with their feet 25 cm apart. Throughout the experiment, a tape was used to ensure a consistent distance between participants’ feet while standing. Subjects looked straight ahead during the entire trial, with eyes directed toward a target (+) presented on a screen 4 m ahead at eye level. A visual stimulus was presented and remained on the screen for 10 seconds after the (+) sign appeared, allowing subjects to get ready to respond with the appropriate foot and the exact number of steps. We used repeated measures t-test in SPSS to compare the means of ST during SRT and CRT tasks Results. There was no statistically significant difference in ST for SRT task (M=1207.8, SD=73.6) and CRT task (M=1234.1, SD=67.1) (t (7) = - 1.5, p = 0.17) Conclusion. Our results suggest that CRT task has no strong impact on ST. However, the small number of participants must be considered a main factor, which led to this result. en
