I guess it was single fibre then - although he only left the needle in for about 30 seconds then moved to another area. No shocks, just asked me to clench then rest.

I had the nerve conduction study in the same session - no needles, just pads and 3-4 shocks on each bit he was testing.

I've read that even single fibre EMG can miss MG - is this correct?

[He said he wouldn't be able to stick them in my throat for obvious reasons!]
