Rehabilitation device providing locomotion training and method of use

A gait training device for seated or standing gait training comprising:

• a sled coupled to a base, the sled comprising:
• a handle for training arm motion;
• and
• a linkage and gear system operatively connected to the handle for synchronizing arm motion with leg motion, the linkage and gear system operatively connected to at least one footplate;
• the at least one footplate operatively connected to the base, the at least one footplate for securing a foot of a user for gait training;
• and
• a tower operatively connected to the base, the tower comprising a body weight system and a seat for supporting a weight of the user during the gait training, wherein when the user is in a standing position:
• the linkage and gear system causes the handle to trace a single arc from a first maximum translational point to a second maximum translational point through a terminal stance phase and a toe-off phase at a height of the user's hip;
• and
• the handle traces the single arc through a point below both the first maximum translational point and the second maximum translational point.
