[EMG analysis of masticatory muscle fatigue and recovery rate during gum chewing].
An EMG computer analysis system was developed to analyze the mandibular function. The system enabled measurements of the masticatory muscle's rhythm, activity, and power spectrum for the same EMG burst during mastication. This study revealed that a power spectrum analysis was able to be carried out by a fast Fourier transform algorithm of the isometric contraction components of EMG bursts durin...
متن کاملEffect of jaw opening on masticatory muscle EMG-force characteristics.
This study was designed to evaluate the way in which changes in vertical jaw opening affected the relative contributions of various masticatory muscles to bite force production. EMG activity was recorded simultaneously from the masseter, and anterior, middle, and posterior temporalis muscles, during controlled isometric biting at different force levels and vertical jaw openings. EMG-force chara...

متن کاملEffect of Selective Muscle Training Using Visual EMG Biofeedback on Infraspinatus and Posterior Deltoid
We investigated the effects of visual electromyography (EMG) biofeedback during side-lying shoulder external rotation exercise on the EMG amplitude for the posterior deltoid, infraspinatus, and infraspinatus/posterior deltoid EMG activity ratio. Thirty-one asymptomatic subjects were included. Subjects performed side-lying shoulder external rotation exercise with and without visual EMG biofeedba...
متن کامل[Application of EMG biofeedback to patients with mandibular dysfunction. Part 2. Validity of frontal EMG biofeedback].
The purpose of this study was to investigate the mean integral EMG level of the masseter muscle, which was obtained from the EMG biofeedback of the frontal muscle of those patients whom once had a case of mandibular dysfunction, and to use this as an effective means of treatment. Furthermore, the correlation between the psychological characteristics of mandibular dysfunction patients and EMG bi...
