Gait analysis system based on surface electromyography signals

The invention relates to the technical field of biological signal acquisition, in particular to a gait analysis system based on surface electromyography signals. The system comprises a plurality of electrode sheet units, a myoelectricity amplification and filtering module and a main control module; the electromyography signals, collected by the myoelectricity amplification and filtering module, ofthe surface of the human body are digitally converted through the main control module to reduce the interference of the gait analysis system with the walking motion of a monitored person, and therefore the requirement for multi-channel and high-sampling-rate collection of normal walking motion is met. 本发明涉及生物信号采集技术领域，具体涉及种基于表面肌电信号的步态分析系统，包括多个电极片单元、肌电放大与滤波模块和主控制模块，由于通过主控模块将肌电放大与滤波模块采集的人体表面的肌电信号进行数字化转化，以减少步态分析系统对被监测者步行运动的干扰，进而满足对正常步行运动进行多通道和高采样率采集的要求。
