An exercise device upon which a user generally standing upright supported by foot platforms suspended from a frame via linkages in which the linkage lengths and pivot points correspond generally to the users upper and lower legs and hip and knee joints. This device not only allows natural free and spontaneous leg movement, able to simulate such exercises as walking, jogging, running, stepping, skiing or gliding, bicycling, climbing, reverse action and various isolated leg exercises, where the exercises can be performed at random generally without the need to reconfigure the device. This device preferably includes an isolation system capable of simulating natural forces throughout the entire range of movement in the horizontal and / or vertical plane. A safety / suspension system can be provided, alone or in combination with the isolation system, to resist sudden foot movement in the same direction, yet allows a slow and controlled tilting of the linkages whereby the user may simulate uphill and downhill travel.

An exercising system and method for the treatment and rehabilitation of the paralyzed muscles of the legs. Stimulators and sensors are implanted in several of the main muscle groups of the legs. A computerized controller uses wireless signals for communications with the implanted stimulators and sensors. The person receiving the treatment sits on an exercise machine such as a stationery bicycle, a leg press, a rowing machine or other leg exercising machine. The controller determines the position of the legs and transmits a series of commands to the stimulators to provide functional electrical stimulation (FES) to the muscles of the legs, which move the legs in a cyclical or reciprocating manner, such as that needed to pedal a bicycle. Using data provided by the implanted sensors, the controller is able to adjust the stimulation commands sent to the muscles of the legs to control the amount of force exerted by the foot, to limit user fatigue and to keep the foot in a neutral position on the pedal or footrest. Users of the system who are partially paralyzed in the legs can receive an implanted EMG sensor and the controller can synchronize the stimulation of their paralyzed leg muscles with the user's own voluntary activation of their leg muscles.
