Am writing a summary of myasthenic weakness. Have been reading some posts on the site about SFEMG´s and don´t ever remember having any needles involved in the SFEMG I was referred for. Does this sound about right?......
Ulnaris and Facialis muscles......3 and 10 Hz each time with a total of about 50 electric shock/spasms..... no needles but 2 flat electrodes - like silver batteries taped to wrist and neck. Took about 20 minutes.....result averaged out few days later (no decrement on my results)
