  • Patent number: 11154750
    Abstract: 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.

  • Patent number: 10238318
    Abstract: A system and method are provided for targeted training of a person walking on a powered backward moving surface. Kinematic information of motor performance, such as ankle position and velocity, is measured throughout one or more phases of a gait cycle with a detector. The gait phase is determined, and a resistive/assistive force is applied to the leg that differs depending upon the gait phase and the measured kinematic information.

  • Publication number: 20150293200
    Abstract: Systems and methods for producing imaging biomarkers that indicate a tissue state in the nervous system of a subject based on diffusion tensor imaging (“DTI”) of the subject's spinal cord or brain are provided. The imaging biomarker can indicate a tissue state in the central nervous system (e.g., brain or spinal cord) of a subject based on DTI of the subject's spinal cord. As another example, however, the imaging biomarker can indicate a tissue state in the subject's spinal cord based on DTI of the subject's brain. The imaging biomarker is also capable of determining an efficacy of a treatment administered to a subject's spinal cord.

  • Patent number: 5472438
    Abstract: A laparoscopic vacuum delivery device is used for placing an epimysial electrode at the phrenic nerve motor point. The vacuum delivery device is adapted to hold the epimysial electrode while the electrode is introduced through a port into the abdomen during a laparoscopic procedure. The electrode is forcibly held against the diaphragm muscle surface for test stimulation using a suction ported through the delivery device. Multiple test sites may be explored by controlling the suction to and the position of the delivery device. The electrode is secured at an optimal location on the diaphragm muscle using an endoscopic stapler.
