Serial electromyographic findings in Guillain-Barré syndrome patients
We sought to investigate electromyographic characteristics of Guillain-Barré syndrome (GBS) patients in the recovery phase by using serial electromyography (EMG). We included seven GBS patients and assessed their neurologic function at admission and 2, 3 and 6 months post onset using Hughes Function...

We sought to investigate electromyographic characteristics of Guillain-Barré syndrome (GBS) patients in the recovery phase by using serial electromyography (EMG).
