NCS of the tibial nerve proximal to the knee was performed with an optimized high\u2010voltage electrical stimulation (HV\u2010ES) method in 21 normal subjects, 5 with MMN, and 11 with ALS. HV\u2010ES, but not magnetic stimulation, could supramaximally stimulate the cauda equina. Cauda equina motor conduction time determined by HV\u2010ES, but not that with F\u2010waves, correlated well with cauda equina length on magnetic resonance imaging. HV\u2010ES revealed proximal lesions in 4 MMN patients but in none of the ALS patients. Importantly, 1 patient with \u201cMMN without conduction block (CB)\u201d had a CB in the cauda equina. Cauda equina motor conduction is better evaluated by HV\u2010ES than with F\u2010wave study or magnetic stimulation. HV\u2010ES can help to distinguish MMN and \u201cMMN without CB\u201d from ALS.
