Gait analysis systems are provided with body support systems for user's self-adjustment of body weight force when ambulating with the body support systems. The gait analysis systems with the body support systems can be used with a treadmill or over a fixed surface for gait training and analysis with the ability to adjust the user's body weight force during the collection of gait data. Gait data for analysis is collected by an array of sensors mounted on the body support systems in various combinations for sensing gait movement, video imaging, heel strike and toe off states, video processing, feet pressure maps and electromyography.
