Comparative Analysis of Surface Electromyography Features on Bilateral Upper Limbs for Stroke Evaluation: A Preliminary Study

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 10984)


The loss of upper limb functionality caused by stroke significantly influences patients daily living. Surface electromyography (sEMG) has been applied for study of stroke rehabilitation for tens of years. This paper is an attempt to evaluate stroke severity using sEMG. An experiment including four basic upper limb arm motions was carried out, with eleven able-bodied and six stroke patients being employed. Several sEMG features of bilateral upper limbs were compared for their relationship with stroke severity, and results showed that a new proposed feature named Envelope Correlation (EC) performed best. The experiment outcomes provided a prospect to evaluate stroke grade using sEMG.
