Spatial distribution of motor units recruited during electrical stimulation of the quadriceps muscle versus the femoral nerve

Introduction: in this study we investigated differences in the spatial recruitment of motor units (MUs) in the quadriceps when electrical stimulation is applied over the quadriceps belly versus the femoral nerve. Methods: M-waves and mechanical twitches were evoked using over-the-quadriceps and femo...

Methods: M-waves and mechanical twitches were evoked using over-the-quadriceps and femoral nerve stimulation of gradually increasing intensity from 22 young, healthy subjects. Spatial recruitment was investigated using recruitment curves of M-waves recorded from the vastus medialis (VM) and vastus lateralis (VL) and of twitches recorded from the quadriceps. Results: at maximal stimulation intensity (Imax), no differences were found between nerve and over-the-quadriceps stimulation. At submaximal intensities, VL M-wave amplitude was higher for over-the-quadriceps stimulation at 40% Imax, and peak twitch force was greater for nerve stimulation at 60% and 80% Imax. Conclusions: for the VM, MU spatial recruitment during nerve and over-the-quadriceps stimulation of increasing intensity occurred in a similar manner, whereas significant differences were observed for the VL.This work was supported by funds from De Reuter foundation, the Geneva Academic Society, and the Ernest Boninchi foundation.WileyIngeniería Eléctrica y ElectrónicaIngeniaritza Elektrikoa eta Elektronikoa2013info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttps://hdl.handle.net/2454/55595reponame:Academica-e.
