Problems solved by technology

At the same time, after the completion of the STS exercise, due to the decline in the strength of the lower limbs of the elderly and patients, their balance ability is weakened. If they stand up quickly, they will lose their balance and fall.

Abstract

The invention discloses an auxiliary standing chair and a research method for the movement track thereof. The method comprises the following steps: the AMTI three-dimensional force measuring platformis used for three-dimensional pressure measurement in the process of the human body standing up, and the pressure change curve is obtained in the process of the movement; a VICON gait capture system is used to carry out dynamic measurement of the center of gravity of human body in the process of standing-up motion, the track of the center of gravity of human body is obtained, and the dynamic curveis obtained by taking a second derivative. The pressure curve measured by AMTI three-dimensional dynamometer is combined with the track of human body center of gravity, the movement of human body isdivided into three phases, and the three phases are analyzed one by one. The auxiliary kinetic parameters of each stage were obtained. The invention has the beneficial effects that the working efficiency of the seat and the comfort degree of the person are improved, the safety and the reasonable safety speed can ensure that the body of the elderly and the patient is not injured and can also standsafely, and the problem that the hip joint trajectory measurement and the dynamic parameters thereof are difficult to be accurately determined is solved.

Description

technical field [0001] The invention relates to the related technical field of medical equipment engineering, in particular to an auxiliary standing chair and a research method for its motion trajectory. Background technique [0002] Stand-up (sit-to-stand, STS) exercise is the basis of daily life, it requires people to change from sitting to standing posture, normal people perform STS exercise 60±22 times a day on average. The normal elderly in the community have more STS exercises than the elderly in the hospital and the elderly in the rehabilitation ward. Due to the deterioration of muscle strength, joint range of motion and balance ability of the elderly and patients, their STS exercise in daily life is increased. risk. In the face of a huge demand group, there is an urgent need to develop a comfortable and safe auxiliary standing seat. [0003] At present, the existing representative products include the anti-gravity balance assisted standing system of the University ...
