Meige syndrome: a clinical and EMG study
European Neurology
|January 1, 1981
Summary
This study reports two cases of Meige syndrome, characterized by involuntary facial movements. Electromyography (EMG) revealed synchronized muscle activity, aiding comparison with hemifacial spasm.
Area of Science:
- Neurology
- Clinical Neuroscience
Background:
- Meige syndrome, first described in 1910, involves involuntary oral-facial movements.
- Idiopathic hemifacial spasm is a related neurological condition with distinct characteristics.
Purpose of the Study:
- To report two cases of asymptomatic oral-facial dyskinesia consistent with Meige syndrome.
- To compare the clinical and electromyography (EMG) findings of these cases with idiopathic hemifacial spasm.
Main Methods:
- Clinical observation of involuntary movements in two patients.
- Electromyography (EMG) to record muscle activity patterns.
Main Results:
- Patients presented with oral-facial dyskinesia.
- EMG demonstrated spontaneous potential bursts with synchronism across different facial muscles.
Conclusions:
- The clinical and EMG findings in these cases support the diagnostic criteria for Meige syndrome.
- EMG data provides a basis for differentiating Meige syndrome from idiopathic hemifacial spasm.
