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.
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.
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.
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.
手部假肢控制训练的康复效果通常得益于康复方案的早期启动以及使用诸如严肃游戏等现代技术来替代更为传统的方法。在本研究中，我们测试了一款基于虚拟现实的肌电假肢训练严肃游戏，具体而言，测试了游戏设计元素如何影响运动控制和训练的不同方面。
十名身体健全的参与者被要求在虚拟现实环境（VRE）严肃游戏中通过控制一个由线性判别分析（LDA）控制的单自由度虚拟手部假肢来执行一系列任务。这些任务包括抓取和操纵虚拟物体以及受控力调制，后者通过在VRE中传达给参与者的人工反馈来实现。
结果表明，游戏物理特性影响了参与者完成任务的方式，而参与者似乎以不同方式接近和执行任务本身。然而，与预期相反，力反馈并未影响参与者精确调制虚拟假肢施加的抓握力的能力。
基于这些结果，可以得出结论，在所提出的框架内可以训练用户以更具吸引力和及时性的方式发展可能转化为实际假肢使用的运动技能。
