Purpose: The aim of this study was to investigate the kinematics of young adults during ramp climbing at different inclinations. Methods: Twenty-three subjects ascended and descended four steps at four different inclinations(level, $8^{circ},;16^{circ},;24^{circ}$). Temporal-spatial parameters were measured by GaitRite system(standard mat). Groups difference was analysed with on-way ANOVA and Student-Newman-Keuls test. Results: The different kinematics of ramp ascent and descent were analysed and compared to level walking patterns. In ascending ramps, step length and stride length decreased with $24^{circ}$ inclination (p<.000). Stance duration increased with $24^{circ}$, but swing duration decreased with $24^{circ}$ inclination (p<.000). Step time and velocity decreased with $16^{circ}C,;24^{circ}$ inclination (p<.000). Cadence decreased with all inclination($8^{circ},;16^{circ},;24^{circ}$)(p<.000). In descending ramps, step length and stride length, velocity decreased with all inclination($8^{circ},;16^{circ},;-24^{circ}$)(p<.000). Stance duration increased with all inclination($8^{circ},;-16^{circ},;-24^{circ}$) and swing duration decreased with all inclination($-8^{circ},;-16^{circ},;-24^{circ}$)(p<.000). But Step time was not differentiated with different inclinations. Cadence decreased with only. $8^{circ}$ inclination(p<.05). Conclusion: These results suggest that there is a certain inclination angle or angular range where subjects do switch between level walking and ramp walking gait pattern. This shows their motor control strategy between level and ramp walking. Further studies are necessary to confirm and detect the ascent and descent ramp gait patterns.
