TLDR
The individual variation of the electromyographic findings pointed to a differentiated etiology more than to a general increase of activity for emotional reasons, as its location differed among patients and was limited to single muscles in most cases.Abstract:
— In 39 patients with functional disorders of the temporomandibular joint and the muscles of mastication and in 45 dental students without such disorders, the activity in the temporal and masseter muscles was recorded with the subjects seated upright and the mandible at rest. On the average, the level of postural activity in the patients was significantly stronger than in the control group. The increase was not a general trait including all muscles under study, as its location differed among patients and was limited to single muscles in most cases. In the temporal muscles, increased activity was associated with tenderness by palpation. Strong postural activity in the masseter muscles was associated with pain in the cheek and tenderness of the deep part of the muscle. The individual variation of the electromyographic findings pointed to a differentiated etiology more than to a general increase of activity for emotional reasons.read more

Wavelet analysis of masseter muscle activity resulting from stimulation of hypothalamic behavioral sites
TL;DR: This paper compares the traditional techniques of amplitude and mean power frequency analysis with the continuous quantification of frequency content of a signal over time, known as multi-resolution wavelet analysis.

TL;DR: It would be considered that occlusal habits with sustained isometric jaw retrusion might have higher probability to provoke the discomfortableness in the neck, shoulder and back regions than those with protrusion, and that the habits with the retrusions might be more injurious in a supine than in an upright position, while those with the protrusion more injureful in a upright position.

TL;DR: In this paper, the authors investigated whether temporomandibular joint (TMJ) is affected in patients with hemophilia or other coagulation factor disorders (von Willebrand disease and rare factor deficiencies) and the control group consisted of 45 healthy individuals.

Etiology of the pain-dysfunction syndrome
TL;DR: According to the psychophysiologic theory, masticatory muscle spasm is the primary factor in myofascial pain-dysfunction syndrome as mentioned in this paper, and emotional rather than mechanical factors are the prime etiologic agents in stimulating chronic oral habits that produce muscle fatigue.

Dysfunctional temporomandibular joint and muscle pain
TL;DR: The occlusal stability in centric relation was found to be of extreme importance for muscle harmony during swallowing, and electromyographic evidence of muscle balance in rest position could be obtained in more than one-half of the patients in spite of Occlusal interference and temporomandibular joint pain.

Psychological aspects of temporomandibular joint dysfunction
TL;DR: Reasonable grounds exist for asserting that there is a significant relationship of psychological factors to nonorganic TMJ dysfunction, that these factors can be treated, and that this treatment results in relief of physical symptoms as well.
