Association of Jaw and Neck Muscle Coordination with Jaw Opening Activity while Chewing in Healthy Individuals

Abstract

Recently, Ishii et al. (9,10) proposed application of transfer function analyses and coherence function analyses to quantitatively analyze jaw and neck muscle coordination while chewing, which revealed an association of coherency and phase regarding jaw and neck muscle activities while chewing. They also noted that temporal synchronization between jaw closing and neck muscle activities, especially for nonchewing side (NC) neck muscle activity, may be associated with coherency between jaw and neck muscle activities while chewing in healthy individuals (9) .
