Electrical Impedance Myography Quantifies Holding and Pushing During Isometric Muscle Contractions
For frequencies below the intersection point of the Nyquist plots of the muscle at rest and under contraction ${f} \leq {f}_{x}$ , the resistance and reactance are sensitive to the effects of muscle activity, with a strong Pearson correlation of nearly ${0}.{9}$ with torque. During pushing and small extension angles, the averaged accuracy of the estimated torque is ${T} =\pm {200} \pm {5} \ {\text {Nm}}$ .
