두부의 위치와 두진이 지각조절검사에 미치는 영향

Background and Objective: The effects of head position and head shaking on equilibrium have rarely been reported. This study was performed to assess the effects of head position and head shaking on normal healthy young adult using dynamic posturography. Materials and Methods: Twenty two healthy male and female volunteers aged 20-27 years (mean 24.7 years) were assessed by means of dynamic posturography with head centered and then head position changed (head extended and head flexed), and head shaking. SOT (sensory organization test) was tested to determine the effects of head position change and shaking on vestibular function. Results: With head centered, we obtained control data in each condition. In condition 5 of SOT, significant lower score was obtained in both sexes when head extended. Under head flexion and headshaking, no significant effect was found. Conclusion: Head extension induce the impairment of vestibular input, but with head flexed and after headshaking vestibular function does not significantly affected.
