Gait training is an important rehabilitation exercise that requires large space and support. To help it succeed, we developed an automatic speed-controlled treadmill with a sensor frame. A Microsoft Kinect sensor detects the user’s legs, measuring step length and stride width. Leg information is used to control treadmill belt speed. Force sensors in the sensor frame measure support force and its center. Gait analysis using these values is discussed without including treadmill speed control. Subjects were healthy young males aged 22 to 23. Step length indicates the suitable belt speed for a subject. In experiments with automatic belt-speed control, the controller adjusts belt speed automatically based on how a user walks.
