IMPEDANCE MYOGRAPHY (IMG) is a new technology of human neuromuscular system noninvasive testing based on mechanical muscle tone registration with high temporal resolution, in particular, during muscle response to some stimulus specially applied. The basis and the novelty of the approach is that we accept as tonic parameters shear elastic and shear viscous parameters of surface tissues, separately determined through their mechanical impedance measurement by specialized hardware and software. In other words the Impedance Myography is a branch of “Vibrational Viscoelastometry”, related to mechanical properties study of surface muscles in dynamics. The Impedance Myography reveals new opportunities for human neuromuscular system investigation and for development new clinical methods of its condition diagnostic and its treatment monitoring, appending possibilities of known mechanomyography and electromyography methods.
