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.

This invention comprises a low cost, high strength sit-to-stand wheel chair assembly. It is comprised of a base with an upward extension formed of a linear actuator mounted within telescopic members. The telescopic members carry large wheels together with a linkage operated front wheels that are mounted on the forward position of the base. A power linear actuator assembly causes the telescopic members to extend and retract to move the wheelchair assembly from the mobile position to a raised position that permits the base to engage the floor surface and to assist the patient to move from a sitting position to a standing position.

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.
