Abstract

A system for use in rehabilitation of a target patient is provided. The system includes at least two bicycle devices for use by the target patient and a second operator other than the target patient. The at least two bicycle devices each include pedals. At least one of the pedals may have at least one sensor mounted thereon for monitoring operation of the first bicycle device and the target'"'"'s condition. A servomotor is coupled to the pedals for providing gear-like resistance or pedal assistance for the at least two bicycle devices. A controller is programmed to electrically couple the at least two bicycle devices to each other.
