i agree with kitt. i started out with an emg/ncs in 2003 with mild to moderate and two years ago it progressed to severe on the emg/ncs. where else is there to go from there? ha! i dont see any point to that. i get get a full pulmonary function test every 3 months and that has been sinking steadily but its important to gauge that closely at this point so a testing i will go. for pn i dont think i need anymore emg/ncs's unless i improve and thats unlikely. i could see doing different tests if new symptoms develop or new breakthroughs are made.
