英文摘要

Despite many reports on the role of the sensory system in postural control, only a few studies have reported the relationship between sensory disturbance and dynamic postural control. To investigate capabilities for dynamic postural adjustment, this study quantitatively evaluated the response to translational perturbation. Perturbation was experimentally induced in eight subjects (all male, 21.3 ± 1.4 years old) using a platform movable in four directions (forward, backward, right, and left). The response was measured in terms of the center of pressure (COP) using posturography, and electromyography of the trunk and lower extremities, and joint angle using video analysis. The effect of sensory disturbance was examined when wearing translucent goggles and when standing on a soft mat. A significant difference was found in the displacement of COP between the cases with and without sensory disturbance. With disturbance, the medio-lateral and anterior-posterior components of the displacement increased in the posterior and lateral translations, respectively. In addition, postural response against forward translation was not affected by sensory disturbance compared with backward and medio-lateral translation. The results of these analyses provide information useful for the development of balance rehabilitation using translational perturbation.
