Macroelectromyography findings in neuropathies and myopathies
Summary. The possibility of overall recording of the electrical activity generated by muscle fibres making up the motor unit in its entire territory, is the characteristic and main objective of macro-EMG studies. This is possible because of the technical characteristics of the electrode and the recording conditions whose methodology is described. We describe how parameters of macro-EMG are obtained in normal healthy people, and define changes in parameters in pathological neurogenic and myogenic disorders and their value in the follow-up of reinnervation processes
