中风是长期残疾的主要原因，基于虚拟现实（VR）的中风康复在提高动力和功能表现方面是有效的。虽然上肢的大部分功能性伸展和抓握能力得到了恢复，但中风后的捏手运动仍然受损。在这项研究中，我们开发了一个触觉增强VR系统来模拟触觉捏任务，以帮助上肢精细运动功能的恢复。我们招募了16名患有中风的成年人，以验证这种新的VR系统的有效性。每位患者接受30分钟的VR训练课程，每周3次，持续8周。结果测量，Fugl-Meyer评估（FMA），测试评估员les observeres superieurs des Personnes Aesthetics（TEMPA），Wolf运动功能测试（WMFT），方块测试（BBT），和Jamar握力测力计，显示统计学上显著的进步，从前测到后测和随访，表明所提出的系统有效地促进精细运动功能的恢复。此外，我们的证据表明，该系统在某些具有挑战性的条件下也是有效的，例如处于慢性中风阶段或病变和优势手（非优势手受损）的同侧。系统可用性评估表明，参与者强烈打算继续使用这个基于VR的系统在康复。
Stroke is a leading cause of long-term disability, and virtual reality- (VR-) based stroke rehabilitation is effective in increasing motivation and the functional performance. Although much of the functional reach and grasp capabilities of the upper extremities were regained, the pinch movement remains impaired following stroke. In this study, we developed a haptic-enhanced VR system to simulate haptic pinch tasks to assist the recovery of upper-extremity fine motor function. We recruited 16 adults with stroke to verify the efficacy of this new VR system. Each patient received 30 min VR training sessions 3 times per week for 8 weeks. Outcome measures, Fugl-Meyer assessment (FMA), Test Evaluant les Membres superieurs des Personnes Agees (TEMPA), Wolf motor function test (WMFT), Box and Block test (BBT), and Jamar grip dynamometer, showed statistically significant progress from pretest to posttest and follow-up, indicating that the proposed system effectively promoted fine motor recovery of function. Additionally, our evidence suggests that this system was also effective under certain challenging conditions such as being in the chronic stroke phase or a coside of lesion and dominant hand (nondominant hand impaired). System usability assessment indicated that the participants strongly intended to continue using this VR-based system in rehabilitation.
