摘要：

Neuromuscular reflex forces are overwhelmed by inertial reaction forms when a human limb is suddenly displaced. A method, using forced sinusoidal oscillations of the limb when the limb musculature is relaxed, is described for determination of the moment of inertia of the limb. The slope of the graph of peak to peak force versus peak to peak acceleration of each of a series of oscillation frequencies (peak velocity maintained constant) yields an accurate measurement of the moment of inertia. When the moment of inertia is multiplied by the displacement acceleration and the result subtracted from the corresponding force record, neuromuscular reflex forces, and the viscoelastic properties of activated muscle may be observed.
