Chronic ankle instability is a common sports injury that often presents with increased plantarflexion and restricted dorsiflexion. The cumulative effect of peripheral injuries may induce neuroplasticity in the central nervous system. However, the relationship between dorsiflexion or plantarflexion and the central nervous system in patients with chronic ankle instability remains unknown.

慢性踝关节不稳定背屈和跖屈过程中皮质激活的差异：一项任务功能磁共振成像研究。

慢性踝关节不稳定是一种常见的运动损伤，通常表现为跖屈增加和背屈受限。周围损伤的累积效应可能会引起中枢神经系统的神经可塑性。然而，慢性踝关节不稳定患者的背屈或跖屈与中枢神经系统之间的关系仍不清楚。
