A kind of motor function recovery detector

Abstract

The invention provides a motor function restoration detector so as to improve the processing precision of motor function restoration signals and reduce noise mixed in the motor function restoration signals. The detector comprises a control unit, a motor function training and detecting unit and a signal storage and processing unit, wherein the control unit is used for controlling the motor function training and detecting unit to assist the human body with function training and detection of the motor function restoration signals; the signal storage and processing unit is used for storing the human body motor function restoration signals, which are converted into the digital signal format and output by the motor function training and detecting unit, for analysis and reference. The motor function restoration detector can avoid aliasing and interference of excitation signals with electromyographic signals, greatly overcomes the defect that the existing motor function restoration condition mainly relies on artificial judgement and overcomes the defect that processing of interference and aliasing by existing detecting equipment cannot meet requirements.

Description

technical field [0001] The invention relates to the technical field of signal processing of motor function monitoring equipment, and more specifically, relates to a motor function recovery detector. Background technique [0002] Modern rehabilitation science believes that the motor function of the human body after injury can be recovered through appropriate exercise and exercise, for example, by means of a fitness machine. However, traditional fitness machines are usually simple in function and expensive in price, and are mainly used for physical strengthening training or fitness training of healthy people. Not suitable for functional training for rehabilitation of stroke or hemiplegic patients. In the prior art, functional training for rehabilitation of patients with stroke or hemiplegia is usually done by professional physiotherapists. The cost of treatment is high and the course of treatment is long. Users usually need to go to the hospital for training, which brings a l...

Problems solved by technology

However, the signal obtained by feedback is inevitably mixed with the noise generated by the normal physiological and metabolic functions of the human body, and when the stimulating muscles and the evoked myoelectricity occur at the same time and the positions of the stimulating electrodes and the recording electrodes are close, the myoelectric signals The interference mixed with the excitation signal will affect the acquisition accuracy of the signal
