Abstract

Objective

Dyad motor practice is characterized by two learners alternating between physical and observational practice, which can lead to better motor outcomes and reduce practice time compared to physical practice alone. Robot-assisted therapy has become an established neurorehabilitation tool but is limited by high therapy cost and access. Implementing dyad practice in robot-assisted rehabilitation has the potential to improve therapeutic outcomes and/or to achieve them faster. This study aims to determine the effects of dyad practice on motor performance in a wrist-robotic environment to evaluate its potential use in robotic rehabilitation settings.

Methods

Forty-two healthy participants (18–35 years) were randomized into three groups (n = 14): Dyad practice, physical practice with rest and physical practice without rest. Participants practiced a 2 degree-of-freedom gamified wrist movement task for 20 trials using a custom-made wrist robotic device. A motor performance score (MPS) that captured temporal and spatial time-series kinematics was computed at baseline, the end of training and 24 h later to assess retention.

Results

MPS did not differ between groups at baseline. All groups revealed significant performance gains by the end of training. However, dyads outperformed the other groups at the end of training (p < 0.001) and showed higher retention after 24-h (p = 0.02). Median MPS improved by 46.5% in dyads, 25.3% in physical practice-rest, and 33.6% in physical practice-no rest at the end of training compared to baseline.

Conclusion

Compared to physical practice alone, dyad practice leads to superior motor outcomes in a robot-assisted motor learning task. Dyads still outperformed their counterparts 24-h after practice.

Impact statement

Improving motor function in complex motor tasks without increasing required practice time, dyad practice can optimize therapeutic resources. This is particularly impactful in robot-assisted rehabilitation regimens as it would help to improve patients' outcomes and increase care efficiency.

腕部机器人环境中的双人运动学习：共同学习优于单独学习

目标Dyad运动练习的特点是两个学习者交替进行身体练习和观察练习，与单纯的身体练习相比，这种练习能带来更好的运动效果并减少练习时间。机器人辅助治疗已成为一种成熟的神经康复工具，但受限于高昂的治疗费用和可及性。在机器人辅助康复治疗中实施两人一组的练习有可能提高治疗效果和/或更快地达到治疗效果。本研究旨在确定在腕部机器人环境中，双人练习对运动表现的影响，以评估其在机器人康复环境中的潜在用途。方法将42名健康参与者（18-35岁）随机分为三组（n = 14）：分组练习、有休息的体能练习和无休息的体能练习。参与者使用定制的腕部机器人设备练习 2 自由度游戏化腕部运动任务 20 次。在基线、训练结束和 24 小时后计算运动表现评分（MPS），该评分可捕捉时间和空间时间序列运动学，以评估保持率。到训练结束时，所有组的成绩都有明显提高。然而，双人组在训练结束时的表现优于其他组（p <0.001），24 小时后的保持率更高（p = 0.02）。在训练结束时，与基线相比，双人组的中位 MPS 提高了 46.5%，体能练习-休息组提高了 25.3%，体能练习-无休息组提高了 33.6%。影响声明在不增加所需练习时间的情况下提高复杂运动任务中的运动功能，双人练习可以优化治疗资源。这对机器人辅助康复治疗尤其有意义，因为它有助于改善患者的治疗效果并提高护理效率。

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
