足下垂是一种活动障碍，限制踝关节背屈，使步态和平衡的摇摆阶段复杂化。这是神经损伤或中风、脑瘫或多发性硬化症等疾病的常见结果。在这里，我们介绍Cadence，一种低成本的辅助鞋，旨在被动地改善足下垂的人的生物力学和步态节奏。当脚向前穿过地面时，鞋通过使用低摩擦材料区域减少了磨损力的大小，该区域可以在站立阶段收回到鞋中以恢复摩擦。我们报告了Cadence的一项试点研究的结果，该研究显示了该设备对五名因神经系统疾病导致的足下垂的成年人的生物力学和性能影响。在5名受试者中的3名中，我们发现鞋子立即改善了步态力学，在地面上的速度和定性步态舒适度。
Foot Drop is a mobility disorder that limits ankle dorsiflexion, complicating the swing phase of gait and balance. It is a common result of a neurological injury or disease such as stroke, cerebral palsy or multiple sclerosis. Here we present Cadence, a low-cost assistive shoe designed to passively improve the biomechanics and rhythmicity of gait for people with foot drop. The shoe reduces the magnitude of scuffing forces when dragging the foot forward across the ground by using regions of low-friction material that can retract into the shoe to restore friction during stance phase. We report the results from a pilot study of Cadence, which show the biomechanical and performance effects of the device for five adults with foot drop due to neurological disorder. In 3 of the 5 subjects, we found that the shoe immediately improved gait mechanics, speed over ground, and qualitative gait comfort.
