Standard Correction of Vision Worsens EMG Activity of Pericranial Muscles in Chronic TMD Subjects

Figure 3

(a–e) Five different cases involving detection of EMG reactions upon opening of the eyes. (a) A trace representing a bilateral increase in an EMG signal from the anterior temporal musculature. (b) A trace representing a monolateral increase in the EMG signal from the left sternocleidomastoid. (c) A trace representing a bilateral increase in the EMG signal from the sovraioidea musculature (anterior abdomen of the digastrics). (d) A trace representing a monolateral decrease in the EMG signal from the RTA. (e) A trace representing the EMG signal from opening of the eyes.
