“…20,24 Neurophysiology: RNS RNS was reported in 16 of 31 studies. [20][21][22][23][24]29,32,33,35,37,38,41,43,[45][46][47] Of these, 8 studies reported on both sfEMG and RNS data (eTable 3, links.lww.com/WNL/D67). [20][21][22]24,29,32,43,45 The association of an abnormal RNS with risk of SGMG was also mixed: 6 of 16 studies (pooled n = 638) 21,33,35,37,38,47 reported that an abnormal RNS (tested in facial nerve, axillary nerve, ulnar nerve, accessory nerve, orbicularis oculi, proximal/distal limb muscles, abductor digiti minimi, flexor carpi ulnaris, nasalis, trapezius, and deltoid muscles) were associated with risk of SGMG.…”
