Stroke is a neurologic disorder considered the first cause of disability worldwide due to motor, cognitive, and sensorial sequels. Balance dysfunctions in stroke survivors increase the risk of falls and physiotherapeutic rehabilitation is essential to reduce it. Virtual reality (VR) seems to be an alternative to conventional physiotherapy (CT), providing virtual environments and multisensorial inputs to train balance in stroke patients. The aim of this study was to assess if immersive VR treatment is more effective than CT to improve balance after stroke. This study got the approval from the Ethics Committee of the University of Almeria. Three chronic ischemic stroke patients were selected. One patient who received 25 sessions of immersive VR intervention for two months was compared with another patient who received equivalent CT and a third patient with no intervention. Balance, gait, risk of falling, and vestibular and visual implications in the equilibrium were assessed. After the interventions, the two patients receiving any of the treatments showed an improvement in balance compared to the untreated patient. In comparison to CT, our results suggest a higher effect of immersive VR in the improvement of balance and a reduction of falls risk due to the active upright work during the VR intervention.

中风患者的沉浸式虚拟现实作为减少姿势障碍和跌倒风险的新方法：一个案例系列。

中风是一种神经系统疾病，被认为是运动，认知和感觉后遗症导致的全球残疾的首位原因。中风幸存者的平衡功能障碍会增加跌倒的风险，物理治疗康复对于减少跌倒的风险至关重要。虚拟现实（VR）似乎是传统物理疗法（CT）的替代方法，它提供虚拟环境和多传感器输入以训练中风患者的平衡能力。这项研究的目的是评估沉浸式VR治疗是否比CT更有效地改善卒中后的平衡。该研究获得了阿尔梅里亚大学伦理委员会的批准。选择了三名慢性缺血性中风患者。将接受25次沉浸式VR干预治疗两个月的一名患者与接受相同CT的另一名患者与未接受干预的另一名患者进行比较。评估平衡，步态，跌倒的风险以及平衡中的前庭和视觉影响。干预后，与未治疗的患者相比，接受任何一种治疗的两名患者的平衡均得到改善。与CT相比，我们的结果表明，由于VR干预期间积极的直立工作，沉浸式VR在改善平衡和降低跌倒风险方面具有更高的效果。与未治疗的患者相比，接受任何一种治疗的两名患者的平衡性均得到改善。与CT相比，我们的结果表明，由于VR干预期间积极的直立工作，沉浸式VR在改善平衡和降低跌倒风险方面具有更高的效果。与未治疗的患者相比，接受任何一种治疗的两名患者的平衡性均得到改善。与CT相比，我们的结果表明，由于VR干预期间积极的直立工作，沉浸式VR在改善平衡和降低跌倒风险方面具有更高的效果。
