There are also a few things that can cause a false negative on the sfemg - it relies heavily on the technician's skill and experience, and with MG, the muscles will perform more normally if they're cold. I can't find the study but the difference of a few degrees cooler can easily tip you from positive to negative. Also maybe it was just a good day for you or they tested the wrong muscles.
I hope the appointment went well |
