Analysis of Stable sEMG Features for Bilateral Upper Limb Motion

It is evident that the objective physiology-based diagnostic methods are desired to improve the evaluation efficiency for stroke assessment, however the assessment relies mainly on the diagnosis scale and the experience of the therapists in clinic. This paper aims to evaluate the features based on sEMG from bilateral upper limb, which can be used to show the bilateral upper limb differences and to map the stroke scale. Preliminary experiments were conducted on eleven healthy subjects and some classical and innovative features were evaluated. With all the work of this paper, we anticipate that Root Mean Square (RMS), Crest Factor (CF) and Impulse Factor (I), are able to be used to evaluate stroke scale.
