Rehabilitation device and method

A rehabilitation device having automated, multi-positional elements comprising:

• a frame with at least one cross bar and a base member,
• the frame having a first vertical support for a seat and an articulating second vertical support having a pivot joint and supporting a set of handlebars,
• a horizontal support attached to the first vertical support, and a pedal assembly;
• a motor resistance unit coupled to the pedal assembly by a coupling mechanism;
• wherein there are at least two actuators on the pedal assembly,
• the pedal assembly comprising a crank axle and an upper and lower crank arm extending from each end of the crank axle wherein the at least two actuators are on each of the crank arms thereby altering the circumferential diameter of the pedal assembly;
• and
• wherein there may be a plurality of linear actuators for eliciting movement of the seat and the second vertical support.

A portable rehabilitation device comprising:

• a motor resistance unit having a housing;
• a plurality of sensors and a microprocessor contained within the housing;
• a pedal assembly operably connected to the motor resistance unit,
• wherein the motor resistance unit automatically adjusts the rotational speed or simulated resistance,
• wherein the pedal assembly comprises a crank axle and an upper and a lower crank arm extending from each end of the crank axle wherein the at least two actuators are on each of the crank arms thereby altering the circumferential diameter of the pedal assembly;
• and
• a coupling mechanism that operably connects the pedal assembly to the motor resistance unit.
