Abstract(s)
A disfunção temporomandibular (DTM) é uma disfunção prevalente a nível mundial,
apresentado pela limitação funcional e alterações posturais. Objetivo: verificar a relação entre a
presença ou não de DTM e a postura do quadrante superior, nomeadamente do ângulo crânio-vertebral
durante a trinca e a mastigação, da omoplata e acrómio. Métodos: a amostra foi constituída por 30
estudantes de Fisioterapia da Universidade Fernando Pessoa, com uma média de idade de 22,27 anos,
divididos em dois grupos: um grupo com DTM e grupo sem DTM. Para a distribuição dos participantes
entre grupos utilizou-se o índice de anamnésico de Fonseca. Foi avaliada a postura através da utilização
do software de avaliação postural (SAPO), registando o ângulo acrómio, da omoplata e ângulo crâniovertebral
e comparar este com a trina e mastigação. Resultados: Verificou-se uma angulação crâniovertebral
superior de forma significativa entre os grupos sem mastigação, durante a trinca e mastigação
no grupo com DTM. 40,0% possuíam DTM leve, 46,6% DTM moderada e 13,3% DTM severa. No
grupo sem DTM verificou-se correlação positiva moderada entre o ângulo crânio-vertebral trinca e
ângulo crânio-vertebral. No grupo com DTM verificou-se uma correlação positiva moderada entre o
ângulo crânio vertebral trinca e o ângulo craniovertebral e, por fim o ângulo omoplata e DTM score
apresentaram uma correlação negativa fraca. Conclusão: Neste estudo apenas o grupo com DTM
apresentou um ângulo crânio-vertebral significativamente superior, sem mastigação e durante a fase da
trinca e mastigação, assim como, um aumento significativo deste ângulo durante a trinca.
Temporomandibular dysfunction (TMD) is a prevalent dysfunction worldwide, known as functional limitation and postural changes. Objective: to analyze the relationship between the presence of TMD and the posture of the upper quadrant, namely the cranium-vertebral angle during the crack and chewing, of the shoulder and the acromion angles. Methods: The sample consisted of 30 Physical Therapy students from the Fernando Pessoa University, with a mean age of 22.27 years, divided into two groups: one group with TMD and another without TMD. For the distribution of the participants between groups, the Fonseca anamnestic index was used. The posture was evaluated through the use of the postural evaluation software (SAPO), recording the acromial angle, shoulder angle and craniumvertebral angle and compare during crack and mastication. Results: There were a higher significant angle between groups in the cranium-vertebral angle, during crack and mastication in the TMD group. 40.0% had mild TMD, 46.6% had moderate TMD and 13.3% had severe TMD. In the group with no TMD there was a moderate positive correlation between the cranial-vertebral angle and the craniumvertebral angle. In the group with TMD there was a moderate positive correlation between the vertebral skull angle and the craniovertebral angle, and finally the shoulder blade angle and DTM score showed a weak negative correlation. Conclusion: In this study only the TMD group presented a significantly superior craniovertebral angle, without mastication and during the crack and chewing phase, as well as a significant increase of this angle during the crack.
