Description

Sit down and stand up functional assessment training system

technical field

The invention relates to a sports training device, in particular to a sit down and stand up function evaluation training system.

Background technique

According to statistics, the annual incidence rates of cerebrovascular disease, Parkinson's disease, traumatic brain injury and spinal cord injury in my country are 219/100,000, 100/100,000, 55.4/100,000 and 6/100,000 respectively. And because of aging population, frequent occurrence of natural disasters and increase in accidents, the incidence rate is increasing year by year. These diseases and injuries can cause squat-stand dysfunction. Sitting and standing are functional activities that are performed multiple times a day to maintain functional independence. Transferring and toileting are directly related to this on various ADL scales for assessing disability (such as the Barthel scale), and Usually accounts for a large proportion of the score.

Clinically, the patient's squatting and standing function is generally observed by naked eyes or using simple timing tools. More complex kinematics and dynamics evaluations need to be carried out through high-speed cameras and motion analysis systems. In terms of squat and stand up functional training, the therapist generally performs corresponding specific exercises and integrated exercises for specific problems that cause squat and stand up dysfunction, such as muscle strength, balance, and spasticity. At present, there is still a lack of intelligent equipment for the overall training of squatting and standing functions.
