Reorganization of muscle activity in patients with chronic temporomandibular disorders

Highlights • We examined reorganization of masticatory muscle activity in chronic TMD patients. • A functional index of EMG for maximal clenching and gum chewing was introduced. • TMD patients have reduced cooperation and coordination between masticatory muscles. • TMD patients recruited the balanci...

Description
Summary:Highlights • We examined reorganization of masticatory muscle activity in chronic TMD patients. • A functional index of EMG for maximal clenching and gum chewing was introduced. • TMD patients have reduced cooperation and coordination between masticatory muscles. • TMD patients recruited the balancing side more than the control group. • Worse functional index was associated with more severe symptomatology.
