  • Stress-induced muscular activity in mandibular dysfunction: effects of biofeedback training.

    • Surface electromyographic (EMG) recordings from the left and right masseteric areas during physical and psychological induced stress were obtained from 20 patients with mandibular dysfunction and 20 healthy controls. Integrated electromyographic activity was not significantly different for the two sides but was higher for patients than for controls during both stress and relaxation. Anxiety level, as measured with the Taylor Manifest Anxiety Scale, was higher for patients. Biofeedback treatment for the patients resulted in significantly reduced signs and symptoms of mandibular dysfunction. When the test procedures were repeated, the controls had not changed in their electromyographic responses during stress, whereas the patients showed a significant decrease in this respect. The results obtained are discussed in terms of a systems-oriented etiological concept.

  • Variability in electromyographic surface recordings of the human masseter muscle.
  • 1989
  • Ingår i: Electromyography and clinical neurophysiology. - 0301-150X. ; 29:2, s. 105-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Serial registrations of integrated unilateral surface masseter EMG were performed in eight healthy subjects in the rest position, during controlled gentle biting and during maximal clenching at five different sessions in order to analyse the variability. The recording conditions were standardised. The EMG activity for the group did not differ significantly between the sessions at any level but individual variations were great in the rest position both within and between days. Good consistency was found at controlled force levels. Temporally stable measurements of masseter activity which permit quantitative comparisons thus seem possible.
