The statistical method of motor unit number estimation (MUNE) uses the natural stochastic variation in a muscle’s compound response to electrical stimulation to obtain an estimate of the number of recruitable motor units. The current method assumes that this variation follows a Poisson distribution. We present an alternative that instead assumes a binomial distribution. Results of computer simu...

The dependence of the form of the electromyogram (EMG)-force relation on key motoneuron and muscle properties was explored using a simulation approach. Surface EMG signals and isometric forces were simulated using existing motoneuron pool, muscle force, and surface EMG models, based primarily on reported properties of the first dorsal interosseous (FDI) muscle in man. Our simulation results ind...

Objective: Fibrillation potentials and positive sharp waves are pathologic spontaneous potentials which originate disconnection anywhere betweenanterior hornof medulla spinalisto muscle fiber in the motor unit. In clinical practice, the presence and if present the intensity of the spontaneous denervation potentials has been evaluated. In this study, the relations between their amplitudes and pa...
