Myoelectric manifestations of jaw elevator muscle fatigue and recovery in healthy and TMD subjects

Journal of Oral Rehabilitation, 05/02/2012

The results showed that the slope of the mean power spectral frequency (MNF) and the initial average rectified value (ARV) could be used to monitor fatigue of the jaw elevators, the temporalis anterior and masseter muscle show the same myoelectric manifestations of fatigue and recovery and the initial values of MNF and ARV were lower in patients with muscle–related temporomandibular disorders (TMD). The assessment of myoelectric manifestations of fatigue in the masticatory muscles may assist in the clinical assessment of TMDs.
