The<unk>  <unk>  or<unk>  motor action potential is an electromyography investigation (electrical study of<unk>  function). The<unk>  idealizes the summation of a group of almost simultaneous action potentials from several<unk>  fibers in the same area. These are usually evoked by stimulation of the motor nerve. Patients that suffer from critical illness myopathy, which is a frequent cause of weakness seen in patients in hospital intensive care units, have prolonged<unk> .
