System, methods, and other embodiments described herein relate to a device for providing mobility assistance to a user. In one embodiment, a mobility system includes a support component including at least a waist device that is configured to secure the mobility system to the user at a waist area of the user. The mobility system includes a limb attached to the support component and extendable from the support component to a floor when the user is in a standing position. The limb is configured to support the user by providing a rigid structure between the floor and the user. The limb is configured to assist the user in transitioning from a seated position to the standing position by applying a substantially upward force to the user through the support component when transitioning to the standing position.

A system for physical rehabilitation is disclosed. The system comprises a plurality of motors configured to be coupled to a ceiling, and a plurality of cable portions. Each cable portion is connected at a first end to a motor, among the plurality of motors, and connected at a second end to a connector element for attaching to a patient. The system also comprises a controller in operative communication with the plurality of motors to move the connector element in relation to a staircase. The controller is configured to adjust one or both of position and speed of the connector element based on tracked kinematics of the patient as the patient moves along the staircase.

An apparatus for assisting a user with safer descent of a stairway that has at least one handrail. The apparatus essentially serves as a second handrail which the user can hold onto and depend on to support their weight, while holding onto a handrail while they descend the stairway. The user would use the apparatus in the handrail engaged configuration when descending a stairway, and in the stowed configuration for all other venues. The portability allows the user to bring the apparatus with them everywhere, enabling the user to become comfortable and confident with the apparatus' use.

Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.

A method and apparatus for recognizing a gait motion are provided. The apparatus may set a gait motion recognition period based on measured right and left hip joint angle information, may input, to a trained neural network, right and left hip joint angle information and vertical acceleration information measured during the gait motion recognition period, and may recognize a gait motion.

A system for physical rehabilitation is disclosed. The system may comprise a plurality of motors configured to be coupled to a ceiling; a plurality of cable portions, wherein each cable portion is connected at a first end to a motor and connected at a second end to a connector element; and a controller in operative communication with the plurality of motors to move the connector element in relation to a staircase.

Embodiments of crutches are disclosed. A crutch has a main body having a substantially vertical tubular member with a plurality of apertures formed therein; an angled portion extending upwardly from the substantially vertical tubular member; an arm rest support extending perpendicularly from the angled portion for receiving an arm rest; and a handle extending outwardly from the arm rest support. The crutch further includes a leg telescopically received into the substantially vertical tubular member, and a foot exchangably received by the leg.

Disclosed herein are novel embodiments of progressive mobility aid devices. Such progressive mobility aid devices are designed to progress through a variety of configurations to accommodate the use of the progressive mobility aid device in a safe and secure manner as the user of the progressive mobility aid device traverses a variety of surfaces and terrain such as traversing irregular surfaces including sidewalks and stone-based surfaces; loose surfaces and terrain including gravel and sand; soft surfaces including wet ground and carpeted surfaces; and variable gradient surfaces including stairs and inclining or declining surfaces and terrain. The progressive mobility aid devices accommodate such uses with an articulating design that provides for front legs of the progressive mobility aid device to be pivotably adjusted with respect to the rear legs of the progressive mobility aid device, and with wheel assemblies that are selectively deployable and retractable.

A system for assisting a user with navigating a set of stairs includes a pulley system positioned adjacent to the stairs, the pulley system including a first pulley, a second pulley, and an elongated member coupled to and looped around the first pulley and the second pulley. The system further includes a motor coupled to the first pulley, a sensing assembly operatively coupled to the pulley system, the sensing assembly being structured and configured to sense that a force is being applied to or that is about to be applied to the elongated member by the user, and a controller coupled to the motor and the sensing assembly. The controller is structured and configured to, responsive to the sensing assembly sensing the force, turn the motor on to drive the first pulley.

A moving body includes: a plurality of wheels capable of rotating around a plurality of rotating shafts disposed on a circumference around a common axis; and a supporting unit supporting the plurality of rotating shafts to be capable of revolving around the axis. A first power source is connected to the plurality of wheels to be capable of transmitting power so as to rotate the plurality of wheels. A second power source is connected to the supporting unit to be capable of transmitting power so as to revolve the plurality of wheels.
