Respiratory Biofeedback Sensor for Yoga Practice for Youth with Chronic Pain.

项目摘要 此小型企业技术转让(STTR)第一阶段应用程序提出了 新型无创实时呼吸传感器pneuRIP的研制与试验 呼吸生物反馈对瑜伽的有益影响。将使用PneuRIP来监控 并改善患有慢性疼痛的年轻人在瑜伽中的体式(姿势)和调息(呼吸)。这个 传感器由胸部和腹部周围佩戴的两个感应带组成，用于测量和 用呼吸电感区分隔膜呼吸和胸腔呼吸 体积描记(RIP)。读数在一个小的胸前佩戴的装置上记录和分析 无线传输到iPad上。测量包括胸腔和胸腔之间的相位角 腹部；通过胸腔呼吸的百分比；呼吸频率；以及用力呼吸 指数。该传感器只需很短的时间即可设置，读数可即时提供。 提案的第一部分将开发生物反馈软件。生物反馈组件 会与横隔膜和胸部呼吸之间的同步性有关，而相对的 呼吸的深度。这些信息将在iPad屏幕上以可视方式呈现给用户 两个移动杆的形式--一个对应于胸部，一个对应于腹部。 在研究的第二部分，我们将用生物反馈测试pneuRIP，对象是20名 在一家大型儿科医院参加跨学科儿科慢性疼痛项目 接受瑜伽作为治疗方法之一。瑜伽养生法是8次，每周一次。 受试者将被随机分成两组：一组只接受同步指令 第二组除了呼吸，还将接受生物反馈。结果将标准化 疼痛测量(记录整个方案前后)和呼吸指数(记录 在每个会话期间)。结果将为在瑜伽中使用实时生物反馈的可行性提供依据 使用非侵入性呼吸监测器。

Project Summary This Small Business Technology Transfer (STTR) Phase I application proposes the development and trial of a novel non-invasive real-time breathing sensor – pneuRIP- to show the beneficial effects of respiratory biofeedback on yoga. PneuRIP will be employed to monitor and improve asana (posture) and pranayama (breathing) in yoga in youth with chronic pain. The sensor consists of two inductive bands worn around the chest and abdomen that measure and differentiate diaphragmatic and chest breathing through Respiratory Inductance Plethysmography (RIP). Readings are recorded and analyzed on a small chest-worn unit and wirelessly transmitted to an iPad. Measures include the phase angle between the chest and abdomen; percentage breathing through the ribcage; respiratory rate; and labored breathing index. This sensor takes little time to set up and readings are provided instantaneously. The first part of the proposal will develop the biofeedback software. The biofeedback component will be related to the synchrony between diaphragmatic and chest breathing, and the relative depth of breathing. This information will be presented to the user visually on an iPad screen in the form of 2 moving bars – one corresponding to the chest and one to the belly. In the second part of the study, we will test the pneuRIP with biofeedback with 20 youth with pain enrolled in an interdisciplinary pediatric chronic pain program in a large pediatric hospital receiving yoga as one of the therapies. The yoga regimen is 8 sessions, once per week. Subjects will be randomized into two groups: one receiving instruction only on synchronous breathing; the second group will receive biofeedback in addition. Outcomes will be standardized measures of pain (recorded before and after entire regimen) and breathing indices (recorded during each session). Outcomes will inform the feasibility of using real-time biofeedback in yoga with a non-invasive respiratory monitor.
