A system and method for providing therapy and assessment utilizing vibrotactile feedback is disclosed. Such treatment is useful for the assessment and treatment of disequilibrium, movement and balance disorders. The system and method measures a subject's performance of predetermined tasks with respect to expected parameters using sensors such as force plates, inertial sensors, and three dimensional cameras. Predetermined motions are motions such as stand, sit-to-stand, reach, bend, functional gait, functional gait plus headshake, and other functional tasks. Vibrotactile stimulation may be applied during the subject's performance as disruptive input. Variance and rate of change of variance between measured and expected parameters is used as a tool for assessment of said subject, and is also used for providing real-time vibrotactile training to said subject. The invention is useful in the treatment of Traumatic Brain Injury (TBI), neurologic disorders causing disequilibrium and balance disorders, and the like.

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 sit/stand assistance includes a seat, a frame, a lifting device, and a driving device. This lifting device has a fixed portion connected to the frame and a movable portion pivoted with the seat so as to move the seat up or down. The driving device includes a link, a power portion, and a working rod. One of the power portion and the working rod is pivoted with the link. The other one is pivoted with the frame. When the power portion pushes the working rod, the working rod extends out so as to make said seat moving up or tilting. Hence, it can assist a user from a seated position to a standing position. So, it matches a user's continuous sit-to-stand motion. Plus, it can be directly applied on an existing flush toilet.

A walker to assist a person rising from a seated position, the walker comprising: two or more front legs each having a proximal end, a center and a distal end, the distal end being adapted to contact the ground, one or more cross members secured to and joining the front legs to one another, a handle engaged to the proximal end of each front leg, a joint mechanism engaged to each the front leg, and a rear leg having a proximal end and a distal end, the proximal end being engaged to each joint mechanism allowing the rear legs to pivot relative to the front legs.

A child development sit to stand device comprises a support. At least one fixture is connected to the support for permitting a child to grasp with his hand and raise his own body upwardly under his own ability. A reflective surface is attached to the support for attracting the child to and to use the standing device, facilitating the goal of developing the child's ability to stand. And, a method for assisting in the development of a child to perform a sit to stand movement. The method includes positioning the device into an initial position for the device to be commensurate with the child's ability and, as the child achieves the desired goal of standing, the device is positioned into a more advanced position, increasing the level of difficulty for the child to stand.

A sit-to-stand function assessment method with a non-therapeutic purpose is implemented through a set of sit-to-stand function assessment device. The sit-to-stand function assessment device comprises an upper computer, foot rests, a cushion and a display screen. Sit-to-stand function assessment software is arranged in the upper computer, sole pressure sensors are arranged in the foot rests, and a hip pressure sensor is arranged in the cushion. By adopting the sit-to-stand function assessment device, sit-to-stand function assessment parameters including the maximum pressure of the front portions of the left hip and the right hip during sitting, the maximum pressure of the left sole and the right sole during standing and the average pressure of the left sole and the right sole during standing can be displayed on the display screen in real time through one-time sit-to-stand motion; the maximum pressure change value of the front portions of the left hip and the right hip and the average pressure change value of the front portion of the left hip and the right hip at the stretching earlier stage and the stretching stage of the sit-to-stand process can be obtained through marking time, further the sit-to-stand functions of subjects can be accurately assessed, and the sit-to-stand function assessment method is convenient and feasible.

The sitting to standing lift chair is useful for the elderly and physically impaired when transitioning from a sitting position to a standing position, or vice versa. The chair includes a seat bottom, a seat back rotatably attached to the rear edge of the seat bottom, armrests attached to side edges of the seat back, hand grips on the armrests, a headrest and a footrest rotatably attached to the front edge of the seat bottom. A base and a bottom elevated platform support the other chair components and provide an adjustable height for the chair. The seat bottom is supported on the bottom elevated platform using a sitting to standing mechanism, which provides for raising and lowering the seat bottom while keeping the seat back vertical. Three control switches operate motors for controlling the height of the chair, the position of the footrest and the sitting to standing mechanism.

A therapy tool designed to assist therapist to manually control and facilitate patient elbow and knee flexion-extension during walking, sit to stand, control in standing, and other functions is provided. The therapy tool includes a first cushion adapted to receive at least a portion of a person's shin or forearm, a second cushion adapted to cushion a person's knee, a elongate handle attached the first and second cushions in a manner such that the second cushion is disposed above the first cushion, and a horizontal extension adapted to provide a support surface for the patient.

The invention discloses a sit-to-stand chair, which comprises a chair bracket, a seat, a rotating frame and a driving mechanism, wherein the rotating frame is used for driving the seat to be inclined relative to the chair bracket so as to assist people on the seat to stand up, and the driving mechanism is used for driving the rotating frame to run. One end of the rotating frame and the top of the chair bracket form a rotating pair, the other opposite end of the rotating frame and one end of the seat also form a rotating pair, and a compound hinge driven by the driving mechanism to rotate is arranged in the middle of the rotating frame. The driving mechanism is used for raising up the rotating pair of the rotating frame and the seat by driving the rotating frame to move around the rotating pair formed by the rotating frame and the chair bracket, and expanding the included angle between the rotating frame and the seat by driving the seat to rotate relative to the rotating frame. During the process of assisting standing up, people can feel that the seat has ascending and rotating trends, the standing-up process is steady, and the final rotating angel of the seat is small, so that the old can be effectively prevented from slipping and falling down. The sit-to-stand chair has a simple structure and is wide in application range.
