Background
Facial expressions are external manifestations of human subjective mood and emotion and are non-verbal expressions of human psychological behavior. The contraction of facial muscles drags the facial skin to generate expressions such as joy, anger, sadness and the like. Facial paralysis is a complex group of symptoms mainly manifested by loss of facial expression muscle function and muscular tissue dystrophy. Greatly affecting the quality of life of the patient. Therefore, the detection training of the facial muscle strength is one of the important contents of facial paralysis treatment.
Currently, diagnosis of various diseases such as muscular fatigue and muscular atrophy using an electromyographic signal is the most common method. In the diagnosis process, the facial muscle force detection device is a very important part, and the aim of grading and training the facial muscle force of a patient can be achieved with the help of an accurate measurement result. Simultaneously, still should take exercise to facial muscle power, make the tension and the elasticity that keeps patient's expression muscle, avoid expression muscle atrophy, but also can train the limit and detect to observe the exercise condition in real time. Based on this, facial muscle power detects and trainer must satisfy strict work requirement, if the precision of detection part is not high, will lead to some serious patients' facial muscle power to detect, seriously influences the judgement of doctor to the state of an illness, if the effect of training part can not reach due treatment, can influence treatment greatly.
Because the electromyographic signals are very weak, especially the electromyographic signals of facial muscles, such as orbicularis oris muscles, smiling muscles and the like, the requirement on the sensitivity of the sensing device is very high. Meanwhile, when the electromyographic signals are processed by using a filter in the detection process, effective signals and interference signals are required to have different frequency spectrums, but the electromyographic signals are difficult to extract due to weak electromyographic signals, so that the characteristic values of the electromyographic signals can be only roughly calculated in the calculation process. The prior art is lack of a device capable of sensitively detecting the facial muscle strength.
In the prior art, the needle electrode is also commonly used for detecting the muscle strength of the face, but because the needle electrode is invasive, certain trauma can be caused to a patient, and the operation process is complicated, so that the detection efficiency is very low.
Chinese patent "CN105013144A" discloses a "facial muscle exerciser", which is mainly used for exercising facial muscles and does not quantitatively calibrate the real-time situation of the facial muscle force. Although the purpose of exercise is achieved, accurate judgment cannot be given to the recovery condition of the patient. The facial muscles are exercised by shaking up and down, and the exercise mode has different strength, time, mode and the like, and is not balanced enough for the exercise of the facial muscles. But only has the purpose of exercising facial muscles, and the recovery condition of the strength of the facial muscles cannot be measured in real time. Therefore, it is highly likely that the optimal exercise effect is not obtained.
