Introduction: Cervicalspondyloticmyelopathy(CSM)isacommonspinaldisordercausedbydegenerativechangesinthecervicalspine.Itischaracterizedbycompressionofthespinalcord,resultinginpain,motor,andsensorydeficits.WhiletheupperlimbinvolvementinCSMhasbeenwell-documented,littleattentionhasbeengiventotheimpactonthelumbarmuscles.PreviousstudieshavesuggestedtheexistenceoflumbarmuscleabnormalitiesinCSMpatients,butfewhaveinvestigatedtheseabnormalitiesusingnon-invasivetechniquessuchassurfaceelectromyography(sEMG)featureimages.
