  • Publication number: 20240252379
    Abstract: Orthosis systems are disclosed, having a wearable assembly and a user replaceable orthosis effector assembly. The wearable assembly includes a motor mechanism and a coupler that is movable by the motor mechanism between a starting location and an unloading location. The coupler has a receiving space. The effector assembly couples to the wearable assembly and has a tension element that actuates the effector assembly. A first end of the tension element is seated in the receiving space of the coupler when the effector assembly is coupled to the wearable assembly. The first end of the tension element is releasable from the receiving space when the coupler is in the unloading location, decoupling the effector assembly from the wearable assembly.

  • Publication number: 20240082098
    Abstract: Methods and systems for assessing a stroke rehabilitation outcome of a subject include a home-based brain-controlled interface (BCI) apparatus and a computer processor in communication with the BCI apparatus. The BCI apparatus has i) a portable brain signal acquisition headset that acquires a brain signal from a subject; ii) an orthosis device having a body part interface configured to be coupled to a body part of the subject and a plurality of sensors that generate force data and movement data; and iii) a BCI component that receives the brain signal from the brain signal acquisition headset. The BCI component is capable of controlling the orthosis device. The computer processor performs instructions to process input data to output a rehabilitation outcome prediction for the subject, where the input data includes the brain signal, the force data, the movement data, and background information about the subject.

  • Patent number: 11690774
    Abstract: A system for moving or assisting in movement of a body part of a subject, as well as a rehabilitation system including such a movement assistance system, includes a body part interface configured to be secured to the body part, and a motor-actuated assembly connected to the body part interface to move the body part interface to cause flexion or extension movement of the body part. A force sensing module is configured to measure forces applied between the body part interface and the motor-actuated assembly to ascertain at least one of volitional flexion and volitional extension movement of the body part by the subject, among other functions that may be implemented in movement assistance and rehabilitation systems using the disclosed force sensing module designs.

  • Publication number: 20230008704
    Abstract: System and method for providing both powered and free swing operation in a powered orthotic exoskeleton joint. The joint comprises a processor controllable ratchet wheel and pawl type clutch, configured to engage or disengage upon receiving force from a servo actuator. When the processor determines that the clutch should be engaged, it directs the powered actuator to couple the pawls to the ratchet wheel, allowing torque to be transferred from the joint's powered motor, through the clutch, to the gearing that subsequently controls the motion of the joint. Conversely, the processor can direct the powered actuator to decouple the pawls from the ratchet wheel. This in turn decouples the ratchet wheel from the motor, thus allowing the remainder of the joint and any associated joint gearing to engage in relatively free swing motion, without any interference from the motor.

  • Patent number: 11534358
    Abstract: Rehabilitating an impaired body part of a subject such as a stroke patient includes systems, devices, and methods using an orthosis system configured to attach to the impaired body part and to move or assist in movement of the impaired body part. A control system is configured to operate the orthosis system in a mode in which the orthosis system first allows the subject to move volitionally or attempt to move volitionally the impaired body part in a predefined motion and then operates to move or assist in the predefined motion of the impaired body part. Additional modes of operation include a brain computer interface mode of operation and a mode in which the orthosis system operates in a continuous passive mode of operation comprising a plurality of repetitions of an exercise to move the impaired body part.
