  • Method, apparatus, and system for motorized rehabilitative cycling
    Patent number: 12551744
    Abstract: Provided herein is a method, apparatus, and system a motor-assisted stationary rehabilitation cycle employing a closed-loop control scheme. Methods may include: determining a desired set point rotational speed of a pair of pedals connected to a crankshaft; determining an upper bound and a lower bound about the desired set point rotational speed; determining a crankshaft rotational speed; increasing torque using a motor connected, at least indirectly, to the crankshaft in a first rotational direction, resisting rotation of the crankshaft in response to the rotational speed of the crankshaft approaching the upper bound; and increasing torque using the motor in a second rotational direction, opposite the first rotational direction in response to the rotational speed of the crankshaft approaching the lower bound.
