Wearable sensing system and measurement method for measuring knee joint adduction torque

Abstract

The invention discloses a wearable sensing system and a measuring method for knee-joint adduction torque measurement. The wearable sensing system comprises a power source module for supplying energy to the whole system, a pressure signal collecting module for detecting distribution and variation of plantar pressure in the human walking process, a signal conditioning module for processing pressure distribution variation signals to obtain the amplified and conditioned signals, a Bluetooth transmission module for wirelessly transmitting pressure signals and a pressure signal analysis module for analyzing data of the pressure signals, building a neural network model and predicting the value of the knee-joint adduction torque through the model. The knee-joint adduction torque is measured through the system, and the knee-joint adduction torque can be accurately, reliably monitored in real time; sensors have the advantages of being soft, small in size, easy to wear and the like, and can be comfortably worn on socks, and discomfort or inconvenience of the normal life can be avoided.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a wearable sensing system for measuring the adduction torque of the knee joint, and also relates to a measurement method for measuring the adduction torque of the knee joint. Background technique [0002] The knee joint is the most complex and highly coupled joint in the human body. It has a large range of motion and bears a large leverage force, so it is easily injured. Damage to any one of the components of the knee joint can lead to wear and tear on the knee joint over time, eventually leading to knee osteoarthritis. Numerous studies have shown that knee adduction torque is a good indicator of knee osteoarthritis. Compared with the normal population, patients with knee osteoarthritis tend to have significantly increased knee adduction torque. Therefore, real-time measurement of knee adduction torque is of great significance for patients with knee osteoarthritis. Usuall...

AI Technical Summary

Problems solved by technology

This method has great limitations. First of all, this method requires a large-space laboratory and multiple fixed force plates. It cannot monitor the adduction torque of the knee joint in real time, and the real-time monitoring of the adduction torque of the knee joint has a great impact on the It is of great significance for patients with knee osteoarthritis to judge that it can improve the stress of the knee joint and adjust the gait mode

Second, this method requires expensive measuring equipment and is difficult to popularize
