Lower extremity rehabilitation has seen recent increased interest. New tools are available to improve gait retraining in both adults and children. However, it remains difficult to determine optimal ways to plan interventions due to difficulties in continuously monitoring outcomes in patients undergoing rehabilitation. In this paper, we introduce an extension of the Force Field Adaptation Paradigm, used to quantitatively assess upper extremity motor adaptation, to the lower extremity. The algorithm is implemented on the Lokomat lower extremity gait orthosis and utilized to assess short-term motor adaptation. Establishing an understanding of how healthy adults' motor systems adapt to external perturbations will be important to understanding how the adaptive mechanisms involved in gait are altered by disease.
近年来，下肢康复越来越受到关注。现在有了新的工具来改善成人和儿童的步态再训练。然而，由于难以持续监测接受康复治疗患者的治疗效果，因此确定最佳干预方案仍然很困难。在本文中，我们将用于定量评估上肢运动适应性的力场适应范式扩展到了下肢。该算法在Lokomat下肢步态矫形器上实现，并用于评估短期运动适应性。了解健康成年人的运动系统如何适应外部干扰，对于理解步态中涉及的适应性机制如何因疾病而改变至关重要。
