Abstract
In POEMS syndrome CrowFukase syndrome the proximal conduction of peripheral nerves innervating leg muscles is difficult to assess using conventional nerve conduction studies NCSs when Fwaves or Hreflexes are not detectable Recently we developed a novel magnetic stimulation method to measure cauda equina conduction time CECT using a powerful coil known as a magnetic augmented translumbosacral stimulation coil MATS coil 1 2 3 This method allows us to investigate CECT even in patients with peripheral neuropathy 3 In this study we applied our method to a patient with POEMS syndromeThe patient was a 72yearold man who was unable to walk 5 months after onset Neurological findings at 6 months after onset revealed weakness with muscular atrophy Medical Research Council scale for muscle strength grades proximal arm 4 distal arm 3 proximal leg 3 and distal leg 1 distal dominant sensory disturbance and areflexia of the extremities Wholebody computed
