[Standard electromyographic and kinesiographic parameters in a sample of healthy population]

The authors have examined through the electromygraphic-kinesiographic system provided, the mandibolar movements and the electric activity of the masseter and temporal muscles of group of 25 subjects, aged 22-25 (15 women and 10 men), with complete natural dentition, whose history and clinical examination of cranio-mandibular disorders were negative. The aim of the study is to analyse the values come out by these instrumental researches and to compare them with the already existing literature, trying to obtain standard data of "normality", to be used as comparative and diagnostic parameters for this age range and, on the other hand, as a further method of evaluation for electromyiografic-kinesiographic and electromyiographic analysis of subjects suffering from algic-dysfunctional pathology of the cranio-mandibular apparatus. The analysed champion of healthy subjects, with symmetrical electromyiographic normal values (temporan muscles 0.5-2.5 microvolts, masseter muscles 0.5-2.0 microvolts), presents physiological mandibular movementes along the three space axes: furthermore the results outlined by the existing literature, according to which the female champion has a lower muscular electric potential and mandibular dinamic paths than the male champion, are confirmed. The authors point out the importance of computerised clinical research, not only to get data, but also to store them and to be able to compare them in long term.
