Abstract Recently, various gait rehabilitation robots have been used as therapy in clinical fields for stroke, spinal cord injuries, and several neurological disorders. We investigated the kinematic differences with joint trajectories of two types of gait rehabilitation robots, i.e., exoskeleton and end-effector devices. Furthermore, we compared the end-effector device’s stair climbing and descending motions to actual motions. The exoskeleton device shows larger hip and knee angle than the end-effector device during gait. However, exoskeleton ankle joint was restricted in dorsiflexed position. The end-effector device’s stair climbing motion was similar to actual stair motion, although there was a delayed and lower maximum flexion. Compared with the actual motion, the stair descending motion had a lower maximum flexion angle for both hip and knee joints in the end-effector device. In addition, the end-effector device’s ankle trajectory was aligned with the dorsiflexion angle, while descending to the bottom stair.
