Abstract:  This study is to investigate the character of peripheral neuropathy associated with end stage liver disease and the effect of liver transplantation on peripheral neuropathy. Twenty-five patients admitted for a liver transplantation were involved in this study. All patients underwent neural conduction study before liver transplantation and 6 months after liver transplantation. Based on results of this study, motor amplitude score, motor velocity score (MVS), sensory amplitude score (SAS), and sensory velocity score were calculated. The changes between before and after liver transplantation were evaluated. The SAS and MVS substantially increased after transplantation. Nerve conduction study showed the improvement in sensory and motor nerve after liver transplantation.
