Electromyography
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.
Abnormal EMGs were found in some patients in the 1955 Royal Free Hospital outbreak.[1]
