Posture, Stabilometry, Postural oscillations, Cervical ROM, Tongue position


The tongue is considered an important part of the postural system, so it is fundamental to understand how it can interfere with the humans’ postural oscillations. The aim of this preliminary investigation is to understand the effects of different tongue position and cervical ROM on postural oscillations measured in a stabilometric test. Thirteen voluntary subjects were recruited (30.8 ± 9.7 yrs.; 173.6 ± 14.9 cm; 72.6 ± 15.6 kg) and tested in three different random tongue conditions: comfortable tongue position (CT), palatal spot position (ST) and low tongue position (LT). All tests were performed with open eyes. Stabilometric test were performed with a pressure platform. In addition, the cervical ROM was assessed in the CT condition to create a baseline measurement and to find out baseline relationship with cervical ROM and postural oscillations. Data analysis indicates no significant difference in CoP sway path length for CT / ST / LT (260.7 ± 106.5 mm / 236.9 ± 79.3 mm / 272.9 ± 89.3 mm, respectively). A moderate but significant correlation is present between postural oscillations and cervical rotation ROM (R = -0.59; p = .03), indicating that good postural oscillations are connected with a free ROM of the highest part of the body. The results of this preliminary investigation do not support the use of different tongue position during postural assessment to discriminate some postural interferences of the tongue. At the same time the results suggest the relationship between cervical ROM and stability. These results suggest the necessity to study more in deep this phenomenon with other specific class of subjects.
