Recording of DC-MEG and peripheral signals in stroke patients

Abstract

As a feasibility study modulation DC-magnetoencephalography (DCMEG) was used on patients with unilateral subacute ischemic stroke. In particular, the DCMEG correlate of the affected and the unaffected hemisphere to continuous finger movements was investigated. Simultaneously, the patient's electromyographic (EMG) activity of the lower arm and heartbeat were monitored. DCMEG showed different amplitudes for the affected and the unaffected hemisphere. For both hemispheres, DCMEG data indicated a consistent participation of the patient with respect to the stimulation sequence. This is supported by the EMG activity levels of both sides and the modest increase of the heartrate during finger movements. © 2009 Springer-Verlag.
