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

Electromyographic recordings of human jaw-jerk reflex characteristics evoked under standardized conditions

TL;DR: Reproducible jaw-closing reflexes were evoked following standardized stimuli; subtle variations in motoneurone excitability, such as reflected by differences in jaw-jerk latency between sides, may then become apparent.

An electromyographic study of the immediate effect of an occlusal splint on the postural activity of the anterior temporal and masseter muscles in different body positions with and without visual input
TL;DR: The results indicate that the supine position is the body position to be preferred for centric relation recording as well as for occlusal and splint adjustment.

Bite plates and stabilization splints in mandibular dysfunction. A clinical and electromyographic comparison.
Lars Dahlström,Torgny Haraldson +1 more
TL;DR: Twenty patients with mandibular dysfunction, all women, aged 17-41 years, were randomized for treatment with either a bite plate with a frontal plateau or a full-coverage stabilization splint, and the clinical signs and subjective symptoms improved in both groups.

TL;DR: Extensive literature substantiates the scientific validity of the physical/functional basis of TMD, efficacy of measurement devices and TENS and their use as aids in diagnosis and in establishing a therapeutic neuromuscular dental occlusion.

TL;DR: Five subjects with TMJ dysfunction showed difficulty in making reproducible mandibular border movements as recorded by a pantograph and after one month of treatment, most subjects showed relief of clinical symptoms and improved EMG muscular activity.

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.
