Purpose: The purpose of this study was to investigate characteristics of the muscle activities during level walking and stairs ascending in young adults.
Methods: Fifteen young adult were recruited this study. Muscle activity (BIOPAC System Inc., Santa Barbara, U.SA). Statistical analysis was difference between level and stair walking.
Results: In stance phase, muscle activity of low extremity generally more increased during ramp ascent both young adults. In swing phase, muscle activity of low extremity generally more increased during stairs ascent in young adults.
Conclusion: These results indicate that stair and ramp ascent is more difficult task than level walking in young adults. Muscle activity was more changed at ramp ascent. In the future, we suggest that studies of stair and ramp gait pattern regarding ambulatory patient with disabilities be further studied and an appropriate stairs and ramp inclination will be indicated.
