The aim of this study was to compare the ability of older individuals to maintain an efficient upright stance in contexts of vestibular sensory manipulation, according to their physical activity status. Two groups of healthy older women (aged over 65) free from any disorders (i.e., neurological, motor and metabolic disorders) and vestibular disturbances, participated in this study. One group comprised participants who regularly practiced gentle physical activities, i.e., soft gym, aquarobic, active walking, ballroom dancing (active group, age: 73.4 (5.8) years, = 17), and one group comprised participants who did not practice physical activities (non-active group, age: 73.7 (8.1) years, = 17). The postural control of the two groups was compared in a bipedal reference condition with their eyes open and two vestibular sensory manipulation conditions (i.e., bipolar binaural galvanic vestibular stimulation (GVS) at 3 mA, in accordance with two designs). The main results indicate that there was no difference between the active and the non-active groups in all the conditions. It is likely that the aging process and the type of physical practice had limited the ability of the active group to counteract the effects of vestibular sensory manipulation on postural control more efficiently than the non-active group.
本研究的目的是根据老年人的身体活动状况，比较他们在前庭感觉操纵情况下保持有效直立姿势的能力。两组健康的老年女性（年龄超过65岁），无任何疾病（即神经、运动和代谢疾病）及前庭功能障碍，参与了本研究。一组由定期进行轻度体育活动的参与者组成，即软体操、水中有氧运动、积极步行、交际舞（活跃组，年龄：73.4（5.8）岁，n = 17），另一组由不进行体育活动的参与者组成（非活跃组，年龄：73.7（8.1）岁，n = 17）。在双足参考条件下，比较两组在睁眼和两种前庭感觉操纵条件（即根据两种设计，在3 mA下进行双极双耳直流电前庭刺激（GVS））下的姿势控制。主要结果表明，在所有条件下，活跃组和非活跃组之间没有差异。衰老过程和体育锻炼类型可能限制了活跃组比非活跃组更有效地抵消前庭感觉操纵对姿势控制影响的能力。
