Description

Myoelectric evoked potential meter based on tremor analysis

technical field

Background technique

Myoelectric evoked potential instrument is an important inspection equipment for clinical application analysis and inspection of brain diseases, which is of great significance to clinical scientific research, medical diagnosis, neuroscience research and rehabilitation medicine. It can inspect and study neurological diseases, deafness, tinnitus, hearing impairment, visual impairment, etc. Currently, the clinical departments include neurology, otology, ophthalmology, orthopedics, occupational diseases and sports medicine.

The function of electromyographic evoked potential instrument is not strong enough, and it cannot be diagnosed for some diseases.

At present, the number of Parkinson's patients in the world has exceeded 10 million, and the number of Parkinson's patients in my country has exceeded 5 million, accounting for one-half of the number of patients. It can make the patient's limbs become stiff, gradually lose motor function, and due to the disorder of movement, it can cause the patient to have psychological disorders and intellectual impairment, and lead to a decline in immunity. Its onset is relatively insidious, and early patients do not have obvious symptoms, and it is difficult to detect abnormalities in all aspects of patients, so it is difficult to detect.

At present, the diagnosis of patients with Parkinson's disease mainly relies on the unified Parkinson's disease rating scale, and the evaluation of the condition is achieved through the evaluation and scoring of both doctors and patients. The higher the score, the more severe the disease. This method is highly subjective, and the results need to be evaluated by a doctor. The final score may be quite different from the actual severity of the disease, which is not conducive to treatment. Therefore, it is necessary to design a device that can detect Parkinson's disease.
