Fibr, fibrillation potentials per 10 insertion sites; Amp, amplitude; Dur, duration; Poly, polyphasic motor unit action potentials; IP, interference pattern. The findings are rated from normal (norm.) to highly abnormal (3+). ‘–’ indicates that the response was missing completely. L, left; R, right; n.a., not assessed.
