Evaluation of the Relationship Between Head Posture, Mandibular Movements and Emotional Tension

Introduction: The head, due to its structure and assigned functions, is a unique part of our body. In a number of studies, an association has been confirmed between the base of the head, the cervical spine, and temporomandibular joint disorders. Research objective: The aim of the study was to evaluate the correlation of spatial head position, temporomandibular joint mobility and emotional tension. Material and methods: The study comprised32 participants, aged 20 to 30 years. The position of the head in the sagittal and frontal planes was evaluated via the photogrammetric method. The mobility of the temporomandibular joints was assessed by measurements made with a ruler. Electrodermal activity was measured with the "Bitalino 3DP by BEEVERYCREATIVE" device, and stress intensity assessment was estimated using the PSS-10 scale. Results: A significant (p<0.01) linear correlation was found between electrodermal activity (EDA Min) and the values of angles describing head tilt (FHT1 and HTA). Higher EDA values are associated with higher angle values. No significant correlations (p>0.05) were found between mandibular mobility and EDA scores, or between mandibular mobility measurements and head position. Conclusions: The study revealed a relationship between head positioning and electrodermal EDA activity.
