本研究旨在探讨视觉依赖对痉挛性脑性瘫痪(CP)成人和青少年姿势摆动和视觉运动感觉运动耦合的影响。我们假设患有脑性瘫痪的个体比健康个体表现出更大幅度的摇摆，视觉依赖性(VD)的存在将导致视觉运动方向的不稳定。参与者站在虚拟环境中，在虚拟环境中，视觉场景保持静止或以上下音调连续旋转30度/秒。脑性瘫痪患者在视觉场景运动方向的压力中心和质心反应增强。与视觉独立的患者相比，VD患者在前后方向的频率反应减少。VD提示感觉运动整合不足，这可能导致姿势不稳定和运动功能下降。视觉依赖的脑性瘫痪患者可以从更注重感觉的康复策略中受益。
The current study aimed to explore the impact of visual dependence on sensorimotor coupling of postural sway and visual motion in adults and teens with spastic cerebral palsy (CP). We hypothesized that individuals with CP would exhibit greater magnitudes of sway than healthy individuals, and the presence of visual dependence (VD) would produce instability in the direction of visual motion. Participants stood in a virtual environment in which the visual scene remained static or continuously rotated 30 degree/second in pitch-up or pitch-down. Increased center of pressure and center of mass responses were observed in the direction of visual scene motion in those with CP. Those with VD exhibited reduced frequency responses in anterior-posterior direction than those who were visually independent. VD suggests deficient sensorimotor integration that could contribute to postural instability and reduced motor function. Individuals with CP who are visually dependent may benefit from more sensory focused rehabilitation strategies.
