Abstract
Although quantitative metrics (e.g., walking distance and time) are undeniably significant for walking training, researchers often neglect the quality of walking (stride length, walking speed, and floor reaction force), which is greatly influenced by gait and trunk posture. This explains the absence of clear walking instructions and an appropriate quantitative analysis method for walking quality in current medical practice. Therefore, we propose an omnidirectional walking training robot that improves gait and corrects trunk posture for a better quantity and quality of walking. The robot features a specially designed traction device and an omnidirectional movement mechanism. The combination of these two elements allows the robot to move in any directions and adjust spine alignment. The robot is also clinically proven to be useful in enhancing the users’ balance functions, particularly for those of elderly people aged above 70 years old. The findings demonstrate the promising potential of our robot for practical applications in healthcare facilities.
