Background
Masticatory movement occurs complicatedly and bilaterally. Although the tongue plays an important role in mastication, bilateral tongue function during mastication has not been clarified yet.
Objective
To investigate the effect of food properties on posterior tongue activity and coordination of muscles bilaterally by electromyography (EMG).
Methods
Twenty healthy adults (10 males and...
Background
Retraction of the posterior tongue facilitates bolus formation, food transfer and Stage II transport in chewing and swallowing. Surface electromyography of the neck region (N‐EMG) enabled the evaluation of muscle function at the posterior tongue. Although previous studies showed that food hardness increased masticatory muscles EMG activity and volitional chewing altered swallowing, the...
