Array electromyographic signal acquisition device and lower back pain auxiliary diagnostic system

Abstract

The invention discloses an array electromyographic signal acquisition device and a lower back pain auxiliary diagnostic system. The array electromyographic signal acquisition device comprises a waistband body and a wireless transmission module. A plurality of electrodes which are distributed to form arrays are embedded in the inner side of the waistband body, are connected to the wireless transmission module by an embedded wire and are used for acquiring surface electromyographic signals of the waists of human bodies and transmitting the surface electromyographic signals to the wireless transmission module, and the wireless transmission module is used for transmitting the surface electromyographic signals in a radio form. The array electromyographic signal acquisition device and the lower back pain auxiliary diagnostic system have the advantages that users can easily wear the array electromyographic signal acquisition device and the lower back pain auxiliary diagnostic system on the bodies, the electrodes can be prevented from falling off, heat dissipation can be facilitated, and the comfort and the signal acquisition accuracy and reliability can be improved.

Description

technical field [0001] The invention relates to auxiliary diagnostic equipment for the waist and back of a human body, in particular to an array type myoelectric signal acquisition device and an auxiliary diagnosis system for low back pain. Background technique [0002] Low back pain is an extremely common orthopedic disease, and it is the second leading reason for seeking medical attention after upper respiratory tract infection. About 70%-85% of people in the world have experienced low back pain at least once in their lifetime, and its lifetime prevalence rate can be as high as 60%-90%, and the annual prevalence rate is 15%-45%. Musculoskeletal disorders are the most common and costly occupational health problems in both developing and developed countries. The pain caused by low back pain can limit the activity intensity and range of the lumbar muscles to varying degrees, resulting in muscle atrophy and functional degeneration; and the decrease in muscle contraction abili...

AI Technical Summary

Problems solved by technology

On the one hand, due to differences in clothing, fat and thin, gender, etc., there are certain limitations and inconveniences in measuring the EMG signals of the back and waist, and it takes a long time for the testers to perform electrode pads and block signal transmitters on the testers. installation

On the other hand, since the tester is collecting myoelectric signals when exercising the waist and back, the block signal transmitter will slide during the exercise,
