A lift system has a back panel and a seat panel to provide a seat for a user. The back panel is slidably mounted on a support column via slider so that the back panel can be moved up and down to adjust the seat height. The seat panel can be flipped back to accommodate a user in a standing posture. With the support column, the lift system can be attached to a wheeled frame, a pole, a rotatable arm, a wall or a ceiling depending on the need of the user.

Disclosed embodiments include a stair step assisting device which aids a user, recovering from surgery or having an injury which prevents bearing weight on one foot or ankle, in climbing or descending a staircase. The stair step assisting device has a main body, a lower body and an upper body, which in some embodiments are adjustable relative to one another to accommodate heights of different users and/or different riser heights of different staircases. The device includes lower and upper tread interface surfaces which rest on treads of two adjacent steps, and lower and upper riser interface surfaces which are positioned against risers of two adjacent steps.

This invention relates to a cane/crutch accessory, arranged to be fastened near a distal end (13) of a cane/crutch (11) or similar also equipped with a ferrule (12), by means of a fastening means (5, 17), optionally including adaptor ring/s (15), which accessory includes an arm (28) protruding from said fastening means (5, 17) and a hook-shaped member (6) protruding at an angle in relation to said arm (28), thereby creating a simple grasping device with no moving parts between the arm (6) and the ferrule (12), wherein said arm (6) preferably having a ramp profile (28) to avoid getting caught in objects.

An adjustable step system for assisting a person walking up or down a flight of stairs. The system includes adjustable steps that can be mounted to the stairs of the flight of stairs. The adjustable steps effectively reduce the required vertical height of a step that a person is required to take for each stair. The adjustable steps are also movable and can be positioned at a desired location along the width of the stairs when not in use.

A walker for maintaining balance and stability has extendable and retractable struts positioned within tubular legs for leveling the walker when climbing stairs, a curb or an incline. The struts on each side of the walker are connected to one another via cables which coordinate the motion of the struts so that when the front struts retract within their respective tubular legs the rear struts extend proportionally and vice versa. The cables may be arranged using pulleys mounted within the tubular legs or Bowden cables may be used within each of the tubular legs. User actuated clutches engage the cables to arrest the motion of the struts and temporarily fix them in a desired configuration.

A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.

Walking assistance apparatuses and methods of controlling the walking assistance apparatus are provided. The walking assistance apparatus may recognize a type of a gait task of a user, and may assist a gait of the user to be suitable for the recognized gait task. The walking assistance apparatus may recognize the gait task as various categories using a pre-trained recognizer.

An autonomous wearable leg device employs an array of sensors embedded along a support area, whereby a controller can generate a controlling command and send a controlling command to a prosthetic, orthotic, exoskeletal or wearable component to thereby control the prosthetic, orthotic, exoskeletal or wearable component. A method for controlling autonomous wearable device collects kinetic signals from an array of sensors embedded in a prosthetic, orthotic or exoskeletal component, wherein all values are extracted from at least one feature of the collected kinetic signals, which are applied to a controller that generates a controlling command that is sent to the prosthetic, orthotic exoskeletal component to thereby control the prosthetic, orthotic or exoskeletal component during a portion of a gait cycle.

A walking assistance apparatus includes: a walking assistance attachment to be attached to a leg of a human body and including a variable stiffness mechanism having stiffness that is changeable in a direction where the human bends and stretches the knee by motor driving; and a controller. The controller includes a foot-end motion calculation part configured to receive an output from a sensor to detect motion of a leg and successively calculate a relative velocity of a foot end with reference to a waist of the human body; and a leg state determination part configured to determine shift timing between a swing phase and a stance phase based on the relative velocity of the foot end.

A step aid device has a series of support structures positioned on a flight of stairs to assist a user with a lower leg injury to climb the stairs. A first support structure may be disposed on a first plane. The first support structure has a first side, a second side oppositely disposed from the first side, and a perimeter disposed between the first side and the second side. A second support structure may be disposed on a second plane. The second support structure has a first side, a second side oppositely disposed from the first side, and a perimeter disposed between the first side and the second side. The second support structure the second plane may be offset from the first plane.
