正常人与脊髓灰质炎后遗症患者肌电图的功率谱分析

ANALYSIS OF POWER SPECTRUM OF THE HEALTH SUBJECT AND POLLOMYELITIS PARALYTICS ELECTROMYOGRAM

本实验对正常人和脊髓灰质炎后遗症患者的胫前肌和腓肠肌肌电图(EMG)进行功率谱分析(FFT),描述了两者在FFT中的特点。实验结果表明:正常人FFT相对集中在低频范围,而患者的FFT能量分散在较大的频率范围内。为临床诊断、治疗提供了一个辅助手段和客观指标。

The experiment was to analysc different power spectrum (FFF) of muscle tibalis anterier and gastrocnemius electromyogram(EMG) between health subject and poliomyelitis paralytics. Our results showed that the energy spectrum of health FFF existed in lower fre- quency range and that of the paralytics distributed among widely frequency area.
