[Electromyography in the diagnosis of vibration diseases].
A total of 50 vibration disease patients were assessed by stimulation and needle myography. The authors revealed highly diagnostic parameters: wider range of excitation velocity in motor axons of mixed nerves, preferential decrease in minimal motor velocity, lower number of motor units (MU) functioning, denervation changes of MU action potentials, potentials of spontaneous activity of muscular fibers and fasciculations. Distal muscles of limbs demonstrate the most striking changes in electric activity of MU.
