EMG coherence and spectral analysis in cervical dystonia: discriminative tools to identify dystonic muscles?

Abstract

OBJECTIVE Botulinum toxin injections in the dystonic muscles are the preferred treatment for cervical dystonia (CD), but proper selection of the dystonic muscles remains a challenge. We investigated the use of EMG coherence and autospectral analysis as discriminative tools to identify dystonic muscles in CD patients. METHODS We compared the occurrence of… (More)
