Abstract
With the aggravation of the problem of aging population, all kinds of lower limb paralysis caused by various diseases occur frequently. People's demand for lower limb nursing and rehabilitation treatment is growing. In this paper, combined with intelligent medical technology and lower limb kinematics model, this paper proposes to build a lower limb joint nursing and rehabilitation system based on intelligent medical treatment. It is expected that, through the following limb joint rehabilitation robot as the main rehabilitation means, a smart nursing rehabilitation system which can quickly respond to users and realize remote rehabilitation nursing can be designed. First of all, it is clear that the main body of the lower limb joint rehabilitation system consists of the robot body and the state display system. Then, the sensor, amplifier, and data acquisition card are set in the data acquisition system, and the plantar balance force is detected using a FlexiForce film pressure sensor. The final control system mainly includes the main control module program and the lower limb action recognition program. The motor control software adopts PID regulation method, and the lower limb action recognition adopts SVM one-to-one classification method. After the construction of lower limb joint nursing and rehabilitation system, the accuracy rate of action recognition and classification was tested. In the third experiment, the accuracy of all the movements was 100%. Then, the joint displacement and angle changes of the experimenter assisted by the system were analyzed. The experimenter's knee joint and hip joint show a normal walking state, and the joint angle changes tend to be normal. Ten out of 55 rehabilitation system users were randomly selected for interview survey. The total scores of operation convenience, wearing comfort, intensity suitability, and movement science of the system were 90, 83, 84, and 91, respectively. This shows that the rehabilitation action designed by the system is scientific and easy to operate and can be put into use in rehabilitation training after improving the wearing comfort.
Highlights
How to meet the growing demand for rehabilitation so that patients can be treated in time and get adequate and scientific rehabilitation nursing is the purpose of this paper. erefore, based on the intelligent medical technology and lower limb kinematics model, this paper proposes a lower limb joint nursing and rehabilitation system. e purpose of this paper is to design a kind of lower limb joint rehabilitation robot to carry out the simulation training of lower limb care and rehabilitation, and construct a kind of lower limb joint rehabilitation robot as the main rehabilitation means, which can quickly respond to the needs of users and realize the intelligent nursing and rehabilitation system of remote home rehabilitation nursing
Classification Accuracy of the System. e subjects and the lower limb joint rehabilitation system were tested for five times of recognition and classification of lower limb movements, including forward, backward, left turn, and right turn
Trial Feedback Results. 55 patients with lower limb dyskinesia were invited to try out the lower limb joint rehabilitation robot system developed in this paper. e age and course distribution of the 55 participants were as follows
Summary
There are many problems in medical rehabilitation treatment, such as long time span, heavy work, and patients’ mobility, especially for patients who need lower limb rehabilitation nursing [2]. In the increasingly aging modern society, various diseases such as stroke, joint injury, and hemiplegia cause more and more lower limb paralysis, increasing people’s rehabilitation needs [3]. How to meet the growing demand for rehabilitation so that patients can be treated in time and get adequate and scientific rehabilitation nursing is the purpose of this paper. Erefore, based on the intelligent medical technology and lower limb kinematics model, this paper proposes a lower limb joint nursing and rehabilitation system.
