Split-crank pedaling devices and methods of operation support patient use and rehabilitation, particularly for stroke patients. A split-crank pedaling device includes first and second crank assemblies. First and second motors are operably connected to the first and second crank assemblies. A first shaft sensor produces an indication of a position of the shaft of the first crank assembly. A second shaft sensor produces an indication of a position of the shaft of the second crank assembly. A controller is communicatively connected to the first and second motors and the first and second shaft sensors and calculates a phase error between the positions of the first and second shafts and a predetermined phase relationship between the first and second shafts. The controller operates at least one of the first motor or the second motor to provide a supplemental torque to one of the first crank assembly and the second crank assembly.
