Dynamic topography was generated from the root mean square (RMS) of the HD\u2010sEMG signals to illustrate the anterior neck muscle function in the swallowing process. The averaged power of muscles and the symmetry of swallowing patterns were assessed by objective parameters including average RMS, Left\/Right Energy Ratio, and Left\/Right Energy Difference.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study showed different swallowing patterns between patients with dysphagia and healthy individuals.
