Apparatus and associated methods may relate a to natural gait upper body ergometer and gait therapy (UBEGT) device having a support frame within which is suspended rotationally coordinated left and right natural gait modules (NGMs). A position of each NGM may be defined by corresponding left and right pivot arms which are rotatably coupled to a left and right side of the support frame, respectively, and wherein each gait training module is provided with a corresponding foot support and knee support. The UBEGT may be provided with an upper body ergometer (UBE) rotatably coupled to a front of the support frame and configured to rotate a shaft rotatably connected to the left and right pivot arms when a hand crank is rotated.
