“…The kinesthetic sensation is more accurate during extreme amplitudes of movement, during the intercuspal position and at maximum jaw opening. 21 The greater the kinesthetic acuity, the greater the improvement in postural adjustments, cervical stability and postural stability observed through the minor indices of SI, MMLD and MAPD during isometric contraction.…”

The objective of this study was to evaluate the stability and the distribution of weight of individuals with TMD (Temporomandibular Disorder) when placed in an orthostatic position. Forty female volunteers, participating in this study, were distributed into a control and a TMD group. Clinical examinations of the craniomandibular system and of the neck were performed. Postural stability was evaluated using a stabilographic platform. Through this system, the sway index (SI), the maximum medial-lateral distance (MMLD), the maximum anterior-posterior distance (MAPD) and the medial-lateral symmetry (MLS) could be determined. Tests were performed in the mandibular rest position and during isometric and isotonic contraction. The variables were analyzed through repeated measures ANOVA. The level of significance was p < 0.05. The results of this study indicate that individuals with TMD present more pain in the cervical region (p < 0.05). The group with TMD showed a significant reduction in SI (p < 0.05), MMLD (p < 0.05) and MLS (p < 0.01). Individuals with TMD presented greater postural asymmetry, and cervical pain demonstrated a potential link with an increase in postural stability.

“…In later experiments, Hannam and Tobias [1980] investigated a subject's ability to estimate their jaw position in space. They demonstrated that zones of heightened acuity occur both near the intercuspal position and at maximum jaw separation.…”

Ageing and the Accuracy of Jaw Muscle Control

This study was designed to investigate the effect of ageing upon the accuracy with which subjects control jaw muscle activity during voluntary tooth clenching. The experiment involved the subjects clenching on a force transducer to achieve and maintain a predetermined target force displayed using a biofeedback light bar. The subjects were seventeen healthy, dentally fit males, ranging in age from 22 to 77 years, each of whom performed the experiment on one occasion. Target forces of 0.5, 1 and 2 Kg were demanded, and were maintained for two minutes duration with an equivalent rest period between each task. Subject performance was a measure of the difference between the force achieved and the target force, and was obtained electrically using an integrator controlled by a timing device. The results showed that performance deteriorated both at higher force levels and with increasing age, although there was a wide variation in ability between different individuals.
