Described herein are various embodiments of differential air pressure systems and methods of using and calibration such systems for individuals with impaired mobility. The differential air pressure systems may include an access assist device configured to help a mobility impaired user to stand in a pressure chamber configured to apply a positive pressure on a portion of the user's body in the sealed pressure chamber. The system may also include load sensors configured to measure the user's weight exerted inside and outside the chamber. The system may be calibrated by determining a relationship between the actual weight of the user and the pressure in the chamber, where the actual weight of the user may be measured by more than one load sensor and at least one load sensor is not in the pressure chamber.

An electronic device includes: one or more motion sensors; a memory; and at least one processor connected to the memory and the at least one motion sensor and configured to: calculate a vector on the basis of a sensor value received from the one or more motion sensors; identify changes in time of the x-axis angle and the y-axis angle of the vector over a period of time; detect a start time and an end time of a designated movement based the changes in the x-axis angle and the y-axis angle of the vector over the period of time; and produce exercise information based on the start time and the end time.

The present disclosure relates to a wheelchair treadmill that helps a wheelchair user do an aerobic exercise by rolling driving wheels of a wheelchair in place while in the wheelchair. One embodiment of the present disclosure provides a wheelchair treadmill that supports home fitness of a wheelchair user, the wheelchair treadmill including: a footplate portion configured to assist entry or exit of a wheelchair; a roller portion which has a plurality of roller members disposed in parallel corresponding to first and second driving wheels of the wheelchair and configured to roll in a predetermined rolling direction due to rolling of each of the first and second driving wheels; a support portion coupled to one side of the footplate portion and configured to rollably support the plurality of roller members; and a brake portion rotatably coupled to the support portion and configured to stop the roller portion by being coupled to a rolling shaft of the roller members.

An accessory for wheelchairs for playing football as a sport includes a pair of mutually independent mechanisms, symmetrical in respect of a central longitudinal plane, each of which includes an operating bar (3) and a mechanism made up of a hinged quadrangle, formed of an articulated linkage base which forms a fixed part joined to the body of the chair and which houses a pin (5) for the operating bar (3) to rotate; a propulsion body (9) for propelling and retaining a ball, hinged to the fixed part on a hinge pin (91); an operating lever (17) joined to the lower part of the operating bar (3), and able to turn with said bar; and an auxiliary part (18), hinged to the operating lever (17) on a hinging pin (93), and to the mechanism for propelling and retaining the ball on one hinging pin (92).

A portable exercise apparatus utilized for exercising, stretching, and training multiple muscle groups of the body of a user. The apparatus is adapted to be worn about the waist or carried as a bandolier about the user's body. The apparatus has at least one releasably closable pocket and fixation rings for securing and carrying accessories, such as attachable handles, suspension lines, and elastic bands. The apparatus and methods of use provide the user with a plurality of configurations for assisted exercise regimens and the flexibility to exercise anywhere.

A robotic integrated platform for rehabilitating an upper limb of a subject, comprising: a rehabilitation device, said rehabilitation device comprising a mobile platform, a fixed platform, an upper limb platform and a movement altering device; wherein said mobile platform is movable in regard to said fixed platform, and wherein the upper limb of the subject is in physical contact with said upper limb platform, for exerting a force against said upper limb platform; and wherein said movement altering device alters a movement of said mobile platform; a controller interface for controlling said movement altering device; a computational device for controlling said controller interface, said computational device comprising a VR (virtual reality) module for constructing a VR environment, wherein said computational device provides haptic feedback to the subject through said rehabilitation device; and a VR display for the subject to view the VR environment.

Provided is a swimming assistance apparatus, which is worn on a user's both feet to provide the user with buoyancy, such that the user can float on water and swim in a good swimming style while repeatedly moving the waist from side to side like a fish, thereby reinforcing the user's waist muscles. Persons who have knee joint arthralgia or backache or persons who have disability in the lower body can use the swimming assistance apparatus for medical purposes, such as pain relief or treatment.

Exercise equipment, particularly a linear movable structure and associated selectable elastic resistance bands with or without guide track members are designed to allow low-impact exercises for one or two persons at the same time while permitting either or both participants to remain stationary when utilizing the equipment.

The present invention provides a body lift-assist walker device for gait training is provided by the invention. The patient wears a pressurized body suit over all or a portion of his lower body, and the suit is attached to the walker device. A positive pressure or vacuum condition is applied to the interior of the suit, so that the differential pressure condition across the suit offloads a portion of the patient's body weight to the ground through the supportive walker device to make it easier for him to walk or run. The walker device also includes a lift-assisted body weight support device operated by a constant force mechanism like a pneumatic air cylinder that can lift the patient from a sitting position to a standing position with minimal physical effort. The device provides a portable and convenient system for persons undergoing physical therapy for treatment of gait or balance problems following an injury, stroke, or neurological disorder, or for use by elderly or disabled persons who have encounter difficulties in the sit-to-stand movement or walking.

A therapy system combining sensory input configured to enhance patients balance and stepping is provided. The system may include a mat that selectively receives a plurality of targets. The targets are contacted by the patient's feet and return an audible signal. The system allows a healthcare professional or patient to analyze gait and balance, and correct the same if needed.
