crystal. Thanks for your question. If the study is performed with good quality, an increased jitter is a sign for disturbed neuromuscular transmission. It may be MG but other conditions e.g with reinnervation also show this abnormality. Degree of SFEMG abnormality is related to degree of severity in tested muscle. So, un unsuspected finding of increased jitter must be investigated further; clinically, antiAch antibodies, other EDS tests.
Hello dear master i have a question i had 2 patients with diurnal ptosis and normal SFEMG one of them has injected dysport 2 years ago what do i do? occular MG is possible in physical examination and routine markers are negative(i dont have agrin antibody) both of them are young do you recommend sympthom therapy?thanks a lot
Dear Cooleague Dysport. If that should explain ptosis, SFEMG should be abnormal, provided that you have performed SFEMG in orb oc or frontalis. A negative SFEMG with concomitant weakness is usually a relative strong indicator against MG. Do not give your patients unnecessary treatment unless vital indication. Test that patients again after 3 months Erik Stålberb
Hello dear master, thank you for your valuable educational videos Can you send more clips on how to perform the SFEMG test? (With commentary)
what does it mean if a sfemg comes back abnormal evidence of neuromuscular junction disorder and there were minimal changes?

@@jittertube thank you my dr is concerned about Als and I've been a wreck hoping that's not what it is 😔
