基于肌阻抗图的非侵入式新型肌疲劳标记物
ANew Non-invasive Marker of Muscle Fatigue Based on Electrical Impedance Myography
摘要
Abstract
Purpose:Muscle fatigue is widespread in daily life.In view of the problem that the traditional parameters(amplitude and phase)of electrical impedance myography(EIM)are not real-time enough in the motion scene,this paper combines the biological tissue equivalent circuit model to carry out muscle fatigue reactance response a-nalysis and proposes a new EIM muscle fatigue marker.Method:According to the specific relationship between re-actance and frequency,a method to calibrate musτcle fatigue with reactance peak frequency was proposed.Combined with the bioelectrical impedance characteristic equation,the solution algorithm of fcwas designed to obtain the rele-vant characteristic parameters R0、R∞、α、τ.Secondly,an in vivo experiment platform for biceps brachii muscle fatigue was built to explore the response characteristics of reactance caused by fatigue and verify the effectiveness of peak frequency of reactance to characterize muscle fatigue.Result:In the process of fatigue,there was a downward trend of fcwith the increase of motion cycle,and the decline range of fcafter fatigue was 4～11 kHz.Through Pear-son correlation test analysis,fcand muscle fatigue showed a negative correlation,the absolute value of average cor-relation coefficient was greater than 0.98,fcof before and after muscle fatigue had a significant difference(p＜0.05).Conclusion:The specific shift of peak reactance frequency during and before and after exercise is expected to be a new marker of muscle fatigue.关键词
