Embodiment Construction

[0026] The present invention is based on the Android system knee osteoarthritis movement monitoring method, in figure 1 In the schematic diagram of the overall structure shown, the patient with knee osteoarthritis wears the acceleration sensor 1 and the acceleration sensor 2 on the thigh and calf of the human body respectively, and the X axis of the acceleration sensor is required to be parallel to the downward direction and the Y axis of the sagittal plane of the human body. It is parallel to the left direction of the sagittal plane of the human body, and the Z axis is parallel to the rear direction of the frontal plane of the human body. The standardized rehabilitation training is that the trainee lies flat on his back, one leg is bent, the other leg is straightened, the bent leg is kept still, and the straight leg is raised slowly and smoothly at an angle of about 30°, held for 5 seconds and then lowered slowly, 10 times per group Second-rate. exist figure 2 The schemati...

Abstract

The invention relates to the field of knee osteoarthritis motion monitoring, in particular to a knee osteoarthritis motion monitoring method based on an Android system. The method is characterized in that signals of acceleration sensors worn on thighs and shanks of a human body are collected through a wireless collection device, the signals are transmitted to an Android mobile terminal in a wireless transmission mode, by means of a signal processing system arranged on the Android mobile terminal, the collected acceleration signals are filtered in a Bayesian filtering algorithm, and motion standardization is recognized through a rule induction method. By means of the method, nonstandard motions of a patient during sports can be well recognized, and application requirements of motion monitoring can be well met.

Description

technical field [0001] The invention relates to the field of motion monitoring of knee osteoarthritis (Knee Osteoarthritis, KOA), in particular to a method for monitoring motion of knee osteoarthritis based on an Android system. Background technique [0002] Knee Osteoarthritis Motion Monitoring is a set of monitoring system specially designed for standardized rehabilitation training for patients with knee osteoarthritis. Standardized rehabilitation training can effectively enhance the strength of knee flexion and knee extension muscles, and play a good role in stabilizing the condition and alleviating symptoms, while irregular rehabilitation training will increase the burden on the patient's knee joints, leading to the progression of the disease. deterioration. Therefore, research on knee motion monitoring becomes a necessity. At present, the main means of human motion monitoring are PC-based image analysis and acceleration analysis. Image analysis technology requires hi...
