Abstract
Tradicionalmente, la alteración de las características neuromusculares de un paciente se ha considerado como un posible factor etiológico o agravante de una maloclusión, debido a que los diferentes patrones de actividad muscular pueden modificar las relaciones estructurales y de crecimiento de la mandíbula con el maxilar. Además, numerosos estudios han confirmado que una maloclusión podría alterar la actividad funcional del paciente, de tal manera que, uno de los objetivos del tratamiento ortodóncico sería proporcionar una adecuada normalidad de las características neuromusculares del paciente a través de la corrección de su maloclusión. Actualmente, las técnicas de electromiografía (EMG) y kinesiografía permiten estudiar cuantitativamente la actividad muscular y los movimientos mandibulares de los pacientes en unas condiciones fisiológicas normales, tanto estáticas como dinámicas. Para poder identificar la anormalidad neuromuscular es necesario previamente tener sistematizados unos valores de normalidad que puedan servir como criterios de referencia para poder reconocer y cuantificar las alteraciones funcionales neuromusculares. Según nuestro conocimiento, existe una falta de estudios sobre la población española en condiciones de normalidad fisiológica que proporcionen unos parámetros de referencia sobre la actividad, simetría y patrones de actividad muscular, así como de los rangos normales de amplitud de los movimientos mandibulares. De igual manera, también existe controversia en los diferentes estudios realizados sobre el dimorfismo sexual observado en estas funciones neuromusculares...
Traditionally, impaired neuromuscular characteristics of a patient have been considered as a possible causative or aggravating factor of malocclusion, because different patterns of muscle activity could modify structural and growth relationships of the mandible with the upper jaw. In addition, numerous studies have confirmed that a malocclusion could alter the functional activity of a patient. Therefore, one of the objectives of orthodontic therapy would be to provide an adequate normal neuromuscular environment through the correction of the malocclusion. Currently, the techniques of electromyography (EMG) and kinesiography allow quantitative study of the muscle activity and jaw movements in a patient, both during static and dynamic normal physiological conditions. In order to identify the neuromuscular abnormality, it is necessary to have systematized normal values which could serve as a reference to recognize and quantify functional neuromuscular disorders. To our knowledge, there is a lack of studies on the Spanish population during normal physiological conditions to provide some reference values of activity, symmetry and patterns of muscle activity and normal ranges of amplitude of jaw movements. Similarly, there is also controversy on the sexual dimorphism observed in these neuromuscular functions...
