Figure 5

An example of a single swallow and normal drinking of 100 cc of water by a patient with severe throat problem (dysphagia and odynophagia due to tonsillectomy, second postoperative day, pain score 7). MS – masseter activity, SUB – submental activity, INF – infrahyoid activity. (In real EMG records these lines are of different colors). INF line is very high (normally this line is the lowest at the record), SUB line is lower than normal and almost similar to MS line. The single swallow is prolonged and done in two shares. Drinking is arrhythmic, swallows are small.
