Motor unit number estimates in the tibialis anterior muscle of young, old, and very old men
The rate of motor unit (MU) loss and its influence on the progression of sarcopenia is not well understood. Therefore, the main purpose of this study was to estimate and compare numbers of MUs in theExpand

Detection of motor unit action potentials with surface electrodes: influence of electrode size and spacing
A model of the motor unit action potential was developed to investigate the amplitude and frequency spectrum contributions of motor units, located at various depths within muscle, to the surfaceExpand

Motor unit number estimation by decomposition‐enhanced spike‐triggered averaging: Control data, test–retest reliability, and contractile level effects
Decomposition‐enhanced spike‐triggered averaging (DE‐STA) has been developed as a method for obtaining a motor unit number estimate (MUNE). We describe the method and report control data for theExpand
