Abstract

Background: Stroke is a widespread and complex health issue, with many survivors requiring long-term rehabilitation due to upper-limb impairment. This study is aimed at comparing the perceived usability of two feedback-based stroke therapies: conventional mirror therapy (MT) and immersive virtual reality mirror therapy (VR).

Methods: The study involved 45 participants, divided into three groups: the stroke survivors (n = 15), stroke-free older adults (n = 15), and young controls (n = 15). Participants performed two tasks using both MT and VR in a semirandom sequence. Usability instruments (SUS and NASA-TLX) were applied at the end of the activities, along with two experience-related questions.

Results: The results indicated that both MT and VR had similar levels of perceived usability, with MT being more adaptable and causing less overall discomfort. Conversely, VR increased the perception of task difficulty and prevented participants from diverting their attention from the mirror-based feedback.

Conclusion: While VR was found to be less comfortable than MT, both systems exhibited similar perceived usability. The comfort levels of the goggles may play a crucial role in determining the usability of VR for upper limb rehabilitation after stroke.

传统镜像治疗与沉浸式虚拟现实镜像治疗:中风后的感知可用性。

背景:脑卒中是一个广泛而复杂的健康问题，由于上肢损伤，许多幸存者需要长期康复。本研究旨在比较两种基于反馈的卒中治疗方法:传统镜像治疗(MT)和沉浸式虚拟现实镜像治疗(VR)的感知可用性。方法:该研究涉及45名参与者，分为三组:中风幸存者(n = 15)，无中风的老年人(n = 15)和年轻对照组(n = 15)。参与者以半随机顺序使用MT和VR完成两项任务。在活动结束时应用可用性工具(SUS和NASA-TLX)，以及两个与经验相关的问题。结果:结果表明，MT和VR具有相似的感知可用性水平，MT更具适应性，引起的整体不适更少。相反，VR增加了对任务难度的感知，并阻止参与者将注意力从基于镜子的反馈中转移开来。结论:虽然VR不如MT舒适，但两种系统表现出相似的感知可用性。护目镜的舒适度可能在决定VR在中风后上肢康复中的可用性方面发挥关键作用。
