Spinal cord injury leading to paraplegia affects the mobility and physiological well-being of one in a thousand people. Powered exoskeletons can temporarily restore the ability to walk. Their relevance in daily life is still limited because of low performance beyond ground that is even. CYBATHLON is an international competition promoting improvements in assistive technology. In this article, we present the latest design and results of testing of TWIICE One version 2018, one of the competing devices in the 2020 race.
A person with a motor-complete spinal cord injury at thoracic level T10 participated as race pilot. Training ahead of the race took place over one week at a rate of 2 h per day. The time to perform each of the seven tasks of the competition was recorded together with the number of repetitions. Performance is compared over the training period and against the 2016 race results.
Progression was observed in all tasks and accounted for by both user training and technology improvements. Final competition rank was second out of seven participating teams, with a record time of 4'40". This represents an average improvement of 40% with respect to comparable obstacles of the 2016 race, explaining the two ranks of improvement since then.
These results help understand which features had a positive impact on the real-life performance of the device. Understanding how design affects performance is key information to create devices that really improve the life of people living with paraplegia.
导致截瘫的脊髓损伤影响了千分之一人口的行动能力和生理健康。动力外骨骼可以暂时恢复行走能力。但由于在不平坦地面上的性能较低，它们在日常生活中的相关性仍然有限。CYBATHLON 是一项促进辅助技术改进的国际竞赛。在本文中，我们介绍了 2020 年比赛中参赛设备之一 TWIICE One 版本 2018 的最新设计和测试结果。
一名胸 10 节段完全性脊髓损伤的患者作为参赛飞行员参与。比赛前的训练在一周内进行，每天 2 小时。记录完成比赛的七个任务中的每个任务的时间和重复次数。将训练期间的表现与 2016 年比赛结果进行比较。
所有任务都取得了进展，这是用户培训和技术改进的结果。在七支参赛队伍中最终排名第二，比赛记录时间为 4'40"。这代表着与 2016 年比赛可比障碍物相比，平均提高了 40%，解释了自那以来的两个排名提升。
这些结果有助于了解哪些功能对设备在现实生活中的性能产生了积极影响。了解设计如何影响性能是创造真正改善截瘫患者生活的设备的关键信息。
