Automated Detection and Evaluation of Swallowing Using a Combined EMG/Bioimpedance Measurement System

Figure 2

Schematic of bioimpedance measurement. (a) During breathing, the pharynx is filled with air and tissue resistance is consequently high. (b) On swallowing, the pharynx is closed through muscle action and resistance is reduced.
