为了促进多关节运动考虑肢体协调，我们介绍了一种便携式踝关节辅助测力计（AAE）提供被动踝关节运动在一个特定的曲柄角，每个周期在骑自行车。本研究的目的是验证运动适应效果使用发达的AAE在健康的年轻参与者。我们将商用测力计的踏板改装成一个由马达和刹车驱动的踝关节辅助工具。AAE在骑自行车期间从曲柄角的上止点后90°到下止点向年轻成年参与者提供踝关节背屈辅助。我们获得了1）辅助前后下止点处踝关节背屈角速度的显著差异（）和2）背屈肌肉激活的增加（）。这些影响在取消援助后依然存在。我们的研究结果表明，AAE激活中枢模式发生器，并诱导运动适应踝关节运动的肢体协调在一个运动周期。我们认为，拟议的AAE有助于消除障碍，提供循环运动的康复工具的临床实施。
To promote multi-joint movement considering limb coordination, we introduce a portable ankle assist ergometer (AAE) to deliver passive ankle joint motion at a specific crank angle per cycle during cycling. This study aimed to verify the motor adaptation effect using the developed AAE in healthy young participants. We converted the pedals of a commercial ergometer into an ankle-assisting tool driven by a motor and brake. The AAE delivered ankle dorsiflexion assistance to young adult participants from 90° after the top dead center until the bottom dead center of the crank angle during cycling. We obtained 1) a significant difference between the ankle dorsiflexion angular velocity at the bottom dead center before and immediately after assistance () and 2) an increase in dorsiflexion muscle activation (). These effects persisted after the removal of the assistance. Our results suggest that the AAE activates the central pattern generator and induces motor adaptation of ankle movement by limb coordination during a motion cycle. We believe that the proposed AAE contributes to eliminating barriers to the clinical implementation of the rehabilitation tools delivering cyclic motion.
