Interlimb neural coupling might underlie human bipedal locomotion, which is reflected in the fact that people swing their arms synchronously with leg movement in normal gait. Therefore, arm swing should be included in gait training to provide coordinated interlimb performance. The present study aimed to develop a Rotational Orthosis for Walking with Arm Swing (ROWAS), and evaluate its feasibility from the perspectives of implementation, acceptability and responsiveness. We developed the mechanical structures of the ROWAS system in SolidWorks, and implemented the concept in a prototype. Normal gait data were used as the reference performance of the shoulder, hip, knee and ankle joints of the prototype. The ROWAS prototype was tested for function assessment and further evaluated using five able-bodied subjects for user feedback. The ROWAS prototype produced coordinated performance in the upper and lower limbs, with joint profiles similar to those occurring in normal gait. The subjects reported a stronger feeling of walking with arm swing than without. The ROWAS system was deemed feasible according to the formal assessment criteria.
肢体间神经耦合可能是人类双足行走的基础，这体现在人们在正常步态中手臂与腿部运动同步摆动这一事实上。因此，手臂摆动应纳入步态训练以提供协调的肢体间表现。本研究旨在开发一种带手臂摆动的旋转式步行矫形器（ROWAS），并从实施、可接受性和反应性角度评估其可行性。我们在SolidWorks中开发了ROWAS系统的机械结构，并在一个原型中实现了这一概念。正常步态数据被用作原型肩、髋、膝和踝关节的参考性能。对ROWAS原型进行了功能评估测试，并使用五名身体健全的受试者进行了进一步评估以获取用户反馈。ROWAS原型在上肢和下肢产生了协调的表现，关节轮廓与正常步态中出现的相似。受试者报告称，与不摆动手臂行走相比，摆动手臂行走的感觉更强。根据正式评估标准，ROWAS系统被认为是可行的。
