Abstract

Introduction: Rehabilitation outcomes of hand prosthesis control training generally benefit from an early start in the rehabilitation regimen as well as the use of modern technologies, like serious games, in lieu of more conventional methods. In this study, we tested a virtual reality based myoelectric prosthesis training serious game, specifically how the game design elements affected different aspects of motor control and training.

Methods: Ten able-bodied participants were asked to execute a series of tasks by controlling an LDA-controlled 1-DoF virtual hand prosthesis within a virtual reality environment (VRE) serious game. The tasks included grasping and manipulating virtual objects and controlled force modulation, the latter facilitated by artificial feedback communicated to participants in the VRE.

Results: The results indicated that the game physics affected the way that the participants completed the tasks, while the tasks themselves appeared to be approached and executed in different ways by the participants. Contrary to expectations, however, the force feedback did not influence the participants' ability to precisely modulate the grasping force applied with the virtual prosthesis.

Discussion: Based on these results, it can be concluded that users can be trained within the proposed framework to develop motor skills that might be translated into the use of a real prosthesis, in a more engaging and timely manner.

上肢假肢控制训练虚拟现实严肃游戏设计特点对运动学习的影响
前言:假肢控制训练的康复效果通常受益于早期的康复方案,以及使用现代技术,如严肃游戏,而不是更传统的方法。在本研究中,我们测试了一个基于虚拟现实的肌电义肢训练严肃游戏,特别是游戏设计元素如何影响运动控制和训练的不同方面。方法:在虚拟现实环境(VRE)严肃游戏中,要求10名身体健全的参与者通过控制lda控制的1-DoF虚拟手假体执行一系列任务。任务包括抓取和操纵虚拟物体以及控制力调制,后者通过向VRE参与者传达的人工反馈促进。结果:结果表明,游戏物理影响参与者完成任务的方式,而任务本身似乎被参与者以不同的方式接近和执行。然而,与预期相反,力反馈并没有影响参与者精确调节虚拟假体所施加的抓取力的能力。讨论:基于这些结果,可以得出结论,用户可以在提议的框架内接受训练,以更有吸引力和更及时的方式发展运动技能,这些技能可能会转化为真正的假肢的使用。
