Three-dimensional architecture characteristics and diffusion properties of masticatory muscles assessed with diffusion tensor imaging and diffusion spectrum imaging: a pilot study of differences, reproducibility and sensitivity to microenvironment changes [PDF]
BMC Musculoskeletal DisordersBackground Diffusion spectral imaging (DSI) could overcome the inherent limitation of diffusion tensor imaging (DTI), but its outcomes in masticatory muscle fiber-tracking have not been well-established. Therefore, the objective of this prospective study

Masticatory Muscles Activity in Sport Climbers. [PDF]
Int J Environ Res Public Health, 2020 Masticatory muscle activity during teeth clenching is associated with changes in many physiological parameters throughout the body. Clenching can improve muscle activity, force production, rate of force development, and joint fixation. Hence, teeth clenching and masticatory muscle activity can be important in competitive sports activities.

Pulsatile control of the human masticatory muscles [PDF]
The Journal of Physiology, 2003 Spectral analysis of jaw acceleration confirmed that the human mandible ‘trembles’ at a peak frequency around 6 Hz when held in its rest position and at other stationary jaw openings. The 6 Hz tremor increased during very slow movements of the mandible, but other lower‐frequency peaks became prominent during more rapid jaw movements.

Evaluation of Electromyographic Activity of Masticatory Muscles in Adults with Posterior Crossbite [PDF]
International Journal of Dentistry, 2022 Introduction. There is evidence that patients with posterior crossbite (PXB) have neuromuscular changes in the masticatory muscles. However, up to the present time, the relationship among these changes on the electromyographic activity of the masticatory

Masticatory muscles and the skull: A comparative perspective [PDF]
Archives of Oral Biology, 2006 Masticatory muscles are anatomically and functionally complex in all mammals, but relative sizes, orientation of action lines, and fascial subdivisions vary greatly among different species in association with their particular patterns of occlusion and jaw movement. The most common contraction pattern for moving the jaw laterally involves a force couple

Standardised indexes reduce the variability of masticatory muscles electromyographic values [PDF]
European Journal of Translational MyologyIn dentistry, surface electromyography (sEMG) is currently used in both clinical and research fields to study the electrical activity of the masticatory muscles, such as the anterior Temporals and Masseters, which are easily accessible.

Morphology and Physiology of Masticatory Muscle Motor Units [PDF]
Critical Reviews in Oral Biology & Medicine, 2001 Motor unit territories in masticatory muscles appear to be smaller than territories in limb muscles, and this would suggest a more localized organization of motor control in masticatory muscles. Motor unit cross-sectional areas show a wide range of values, which explains the large variability of motor unit force output.

Electromyographic activity of masticatory muscles in women with osteoporosis [PDF]
Brazilian Dental Journal, 2009 The purpose of this study was to analyze the electromyographic (EMG) activity and the maximal molar bite force in women diagnosed with osteoporosis in the maxillary and mandibular regions, considering the habits and conditions that lead to development of generalized skeletal bone loss, including on face bones, can disturb the functional harmony of the ...

Depression and Resting Masticatory Muscle Activity [PDF]
Journal of Clinical Medicine, 2020 Background: The aim of this study was to determine the influence of moderate depression determined based on Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMDs) Axis II on the bioelectrical resting activity of temporal muscles and masseter muscles. Methods: The research participants were 68 healthy adult women. Of these, 46 people h (
