Walkers encounter surfaces of varying angles every day, from shallow accessible ramps to steep outdoor hills. These individuals must constantly alter their joint mechanics to safely transition between surfaces and avoid falling. The present study aimed to evaluate walking kinematics when encountering a staircase.  A total of 30 participants participated in this study. They were all college students. The results showed that when encountering the stairs, participant decreased their heel velocity, but, did not decrease their walking velocity.
