  • Patent number: 9849048
    Abstract: A mobility system includes a wheeled base, an exoskeleton assembly, and a docking assembly arranged to support the exoskeleton assembly on the wheeled base. The exoskeleton assembly has an upper torso portion, upper leg portions pivotal relative to the torso portion and lower leg portions pivotal relative to respective ones of the upper leg portions. The docking assembly is operable to couple the exoskeleton assembly to the wheeled base in a sitting position. The seating surface in the sitting position and the position control motors for operating the exoskeleton from sitting to standing are all separable from the wheeled base together with the exoskeleton assembly. Alternatively, extensible links may dock the standing exoskeleton to the wheeled base so that the base can trail the exoskeleton through a walking motion.

  • Patent number: 9788936
    Abstract: A corrective device for the positioning of a foot is an apparatus used to treat foot drop. The apparatus includes a spring, a bone anchor assembly, and a tendon anchor assembly. The spring is used to prevent the foot from drooping downward. The spring includes a coil, a first spring coupler, and a second spring coupler. The first spring coupler is used to connect the coil to the bone anchor assembly. The bone anchor assembly anchors the apparatus to a human tibia. The second spring coupler is used to connect the coil to the tendon anchor assembly. The tendon anchor assembly is used to anchor the apparatus to one or more tendons in the foot. Because the coil is anchored above and below the ankle, rotations about the ankle may be limited by the coil.

  • Patent number: 9622518
    Abstract: Articles of apparel include: (a) a garment structure having one or more fabric elements structured and arranged to provide a close fit to at least one predetermined portion of a body (e.g., area(s) of the body for which enhanced position sensing and/or feedback are desired, such as the lower back, the arch of the foot, etc.); and (b) a body position feedback system engaged with or integrally formed as part of the garment structure. The body position feedback system may apply higher tensile or constricting forces to selected portions of the wearer's body, which can help stimulate or interact with nerves and deep tissue receptors located in various portions of the body. The increased forces at selected locations of the body give the wearer sensory feedback regarding the position or orientation of these parts of the body and can improve or accelerate development of “muscle memory.

  • Patent number: 9610208
    Abstract: A lower extremity exoskeleton, configurable to be coupled to a person, includes: leg supports configurable to be coupled to the person's lower limbs and designed to rest on the ground during stance phases, with each leg support having a thigh link and a shank link; two knee joints, each configured to allow flexion and extension between respective shank and thigh links; an exoskeleton trunk configurable to be coupled to the person's upper body, rotatably connectable to the thigh links of the leg supports, allowing for the flexion and extension between the leg supports and the exoskeleton trunk; two hip actuators configured to create torques between the exoskeleton trunk and the leg supports; and at least one power unit capable of providing power to the hip actuators. In use, power is supplied to the hip actuators in an amount to reduce the energy consumed by a user during a walking cycle.

  • Patent number: 9603736
    Abstract: According to various embodiments of this disclosure, an orthopedic rehabilitation device includes a splint, a sole coupled with the splint, and a protective covering. The splint is configured to engage a lower portion of an individual's leg that extends above the individual's ankle. The splint includes at least a first rigid support member that prevents flexing of the lower portion and at least partially immobilizes the individual's ankle. The sole is configured to receive the individual's foot. The sole includes at least a second rigid support member that prevents flexing of the individual's foot. The protective covering is configured to receive the individual's forefoot. The protective covering includes a rigid mesh or solid layer that protects the individual's forefoot from an external force, such as a falling object or any other impact encountered in a work, athletic, training, combat, or other environment where protective apparel is required or recommended.

  • Patent number: 9572588
    Abstract: A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the femoral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.

  • Patent number: 9561395
    Abstract: An ankle strengthening exercise device is disclosed. The device is intuitive and simple to use by a patient even without professional medical supervision since the device indicates a specific movement of a foot by pivoting an ankle of the patient. In particular, the device may have an extension member that can be positioned on a frame of the device. The foot of the patient may engage the device. An elastic member may be secured to the extension member and the foot. The direction of the elastic member indicates the direction the foot of the patient should move by pivoting his or her ankle to specifically work or strengthen and exercise a particular ankle muscle of the patient.
