传统上，姿势是通过分离个体控制途径来确定其具体作用的。然而，如果这些通路对功能上下文有响应，那么当系统同时接收来自多个通路的输入时，它们的响应可能会有所不同。因此，我们可能永远无法完全理解中枢神经系统（CNS）是如何通过在实验室最小环境中进行的研究来组织现实世界中的行为的。这样做的结果是，当实验室的研究结果应用于治疗干预时，干预可能不适合所有情况，也不能完全满足患者的需要。我们将沉浸式动态虚拟环境与姿态平台的运动结合起来，记录对视觉、前庭和本体感觉输入的生物力学和生理反应。虚拟环境具有内容、对比和纹理，因此我们可以检查姿势反应，因为它们可能发生在复杂的现实世界环境中。在本文中，我们具体描述了指导我们选择虚拟技术的因素，并提供了来自年轻人、老年人和双侧迷路丧失患者的数据，以证明多模态输入如何影响他们的姿势反应组织。对未来实验和康复方案的重要意义也进行了讨论。
Posture has traditionally been examined by isolating individual control pathways to determine their specific contributions. However, if these pathways are responsive to functional contexts, then their responses may differ when the system is receiving simultaneous inputs from multiple pathways. Thus, we may never fully understand how the central nervous system (CNS) organizes behaviors in the real world from studies conducted in the minimized environment of the laboratory. The consequence of this is that when findings from the laboratory are applied to therapeutic intervention, the intervention may not be appropriate for all circumstances and will not fully meet the needs of the patient. We have united an immersive dynamic virtual environment with motion of a posture platform to record the biomechanical and physiological responses to combined visual, vestibular, and proprioceptive inputs. The virtual environment possesses content, contrast, and texture so that we can examine postural responses as they might occur in a complex, real-world environment. In this paper we specifically describe the factors guiding our choices of virtual technology and present data from young adults, elderly adults, and an individual with bilateral labyrinthine loss to demonstrate how multimodal inputs influence their postural response organization. Significant implications for future experimental and rehabilitation protocols are also discussed.
