Abstract:

Objective To study the value of combining surface EMG with video EEG and electrocardiogram in the diagnosis of motor seizures in children with epilepsy.Methods Totally 142 children suspected with epilepsy were treated in the Department of Neurology of our hospital from April 2019 to October 2020，all of whom showed recurrent motor seizures，and they were included as research subjects.All the children were examined by surface electromyography，video EEG and electrocardiogram，and the diagnostic results were counted.Results Among the 142 children who were examined，82 were diagnosed with epilepsy;the diagnosis accuracy of pure video EEG was 91.46%(75/82)，which was lower than that of the combined diagnosis (100.0%，82/82)，there being a statistically significant difference(P<0.05).For different types of motor seizures，the onset period and seizure interval of video EEG had typical characteristics，and the synchronous ECG showed the accelerated heart rate at seizures;the surface EMG duration and ECG duration of four different seizure types were within 10 s，and the difference was not statistically significant(P>0.05);motor seizure was synchronized with EMG and ECG.Conclusion The combined monitoring of surface EMG，video EEG and ECG is helpful to detect early epilepsy in children，accurately distinguish the types of motor seizures，and guide clinical treatment.
