目前的工作是支持由欧盟IST计划（项目“的Intrepid - 虚拟现实智能恐惧症的治疗多传感器的可穿戴式系统” - IST - 2002 - 507464）。

协议（GAD）治疗广泛性焦虑症的临床治疗师的办公室内外并举编程。放宽计划是一个“渐进性肌肉放松训练”（PMRT），雅各布森描述的经典程序，涉及拉紧和放松不同的肌肉群，同时注意对比感觉，并遵循“意象”计划相结合。在我们的训练图像是一个轻松的虚拟环境的视觉线索所取代。 治疗师的办公室内。患者参与与治疗师的培训课程，分布在四个星期（每周2节）。每个会话的启动和停止与临床评价，使测量病人的焦虑。 在治疗师的办公室会议的计划： <ol><li>初步临床评价病人的状态; </li><li>病人是与生物传感器，记录/她的生理参数（皮肤电导，心率，呼吸）。基线测量这些参数是注册为3分钟; </li><li>病人戴一个头盔显示器与PC机连接，并处理操纵杆; </li><li>病人开始探索虚拟环境中：一个美丽的热带岛屿的海洋面临。患者，治疗师记录的叙事，乘小船到达该岛，并探索它。行人路，引导他/她通过岛，病人到达的起点，不同的面板显示的方向，以不同的目标区。在上述各领域提供了一个放松运动;在此训练后，语音指南的迹象，患者试图放松他/她，而虚拟环境中的一些元素直接修改由他/她的生理参数记录在实时。因此，病人的即时反馈，收到他/她的激活（如在传统的生物反馈技术）的水平，但与他/她是immersively探索虚拟环境提供额外的价值。目标地区势必： <ul><li>营火：生理参数控制火势，以便减少对患者的生理激活的结果减少火灾，直到它超出; </li><li>波：生理参数的控制，直至海洋成为完全平静的海浪; </li><li>瀑布：减少生理觉醒对应流强度的减少，直到水停止倒下。 </li><li>帐篷：从别人不同，这次演习是定制的患者，可以选择他/她个人的压力事件有关的字或图像。这种技术作为一种应激接种计划，病人可以体验在所选项目的减少大小褪色浮动 - 取决于他/她放松他/她的能力; </li></ul></li><li>一旦完成了虚拟现实会议，生理参数记录再次在休息状态; </li><li>最后的临床评价病人的状态。 </li></ol>以外治疗师的办公室：为了提高培训的效果和增加放松的效果，患者将治疗师的办公室外的实践经历了家庭护理方案的放松技巧。这是实现呈现相同的虚拟环境，在移动设备上的治疗经验。移动设备通过蓝牙连接到的生物传感器，包括心率和皮肤电导。此设备是足够小，并且易于使用要由患者自主处理（见图1）。病人是需要培养放松的能力，每天至少一次，整个治疗的持续时间（一个月）后，治疗师提供的治疗计划。 代表性的成果因为这两种生物反馈和虚拟现实是已知的有效诱导放松，主要预期结果是，这两种方法的结合是减少焦虑在广泛性焦虑症的影响的患者比单独使用这两种技术，更有效。 <img src="/files/ftp_upload/1554/Fig1.jpg" alt="图1" /> 图1：GSR /人力资源的生物传感器模块。

我们的假设是，直接修改虚拟环境中，仅与虚拟现实相比，虚拟现实技术和生物反馈相结合，将导致一个更好，更快地放松学习。如果是这样，这种新仪器创建可用于治疗焦虑症和其他焦虑有关的病状，即使在测试。

广泛性焦虑症（GAD）的特点是一个常数，非特异性的焦虑，干扰与日常生活活动是一种精神障碍。它的高患病率在一般人群中，它会导致严重的局限性，指出有必要寻找新的有效的策略来对待它。加上认知行为治疗，放松代表一个有用的方法治疗GAD的，但它有局限性，这是很难学到的。勇敢的项目是旨在实现一个新的仪器来治疗焦虑有关的疾病，并测试其临床疗效，减少焦虑相关症状。这种方法的创新是虚拟现实和生物反馈相结合，使第一种是直接输出的第二个修改。这样，病人知道他或她通过虚拟环境中的某些功能的实时修改的反应。使用精神病人学会控制这些生理参数的演习，并使用虚拟环境所提供的反馈，以了解他或她的成功。补充使用的便携设备，如PDA或智能手机，让病人在家中执行，独立和自主的，在治疗师的办公室经历了同样的演习。我们的目标是停泊在现实生活中了解到的协议，所以提高病人的处理能力与他们的症状。预期的结果是一个更好，更快地学习放松技巧，从而提高效率的治疗，如果与传统的临床协议相比。
