To assess the effects of an Iyengar yoga program (IYP) on patients with chronic respiratory diseases.
Patients attending lung transplant clinics in a tertiary institution were invited to participate in a two-phase, 12-week IYP that included 2 h biweekly classes. Doctors completed a formal physical and clinical assessment on candidates before enrollment. Patients with New York Association Class III or IV, or dyspnea grade IV were excluded. At baseline and at the end of 12-weeks, patients completed the Hospital Anxiety and Depression Scale (HADS), Chronic Respiratory Questionnaire (CRQ) and Health Utilities Index (HUI). Medication(s), 6 min walk test results and other clinical parameters were also recorded. Patients recorded the effects of the IYP on their daily living in journals. Nonparametric and qualitative methods were used to analyze the data.
Twenty-five patients diagnosed with pulmonary arterial hypertension and chronic obstructive pulmonary disease (mean age 60 years) were invited to participate. At the end of the 12-week period, changes in HADS anxiety and CRQ fatigue scores were statistically significant (P<0.05) and changes in HUI ambulation, pain, emotion and overall score were clinically important. The content of the journals revealed patients' improvement in breathing capacity, mobility, energy, sleep and included positive feedback such as: "increased tidal volume with slowing expiration", "I have an overall feeling of wellbeing" and "excellent amount of energy".
The findings suggest that yoga has significant potential to produce benefits. Potential benefits will be further explored in a national multisite study.
评估艾扬格瑜伽方案（IYP）对慢性呼吸系统疾病患者的影响。
邀请在一家三级医疗机构的肺移植诊所就诊的患者参加一个为期 12 周、分两阶段进行的 IYP，其中包括每两周 2 小时的课程。在入组前，医生对候选者进行了正式的身体和临床评估。排除纽约协会 III 或 IV 级或呼吸困难 IV 级的患者。在基线和 12 周结束时，患者完成医院焦虑和抑郁量表（HADS）、慢性呼吸系统问卷（CRQ）和健康效用指数（HUI）。还记录了药物、6 分钟步行测试结果和其他临床参数。患者在日记中记录了 IYP 对他们日常生活的影响。使用非参数和定性方法分析数据。
邀请了 25 名患有肺动脉高压和慢性阻塞性肺疾病的患者（平均年龄 60 岁）参加。在 12 周结束时，HADS 焦虑和 CRQ 疲劳评分的变化具有统计学意义（P<0.05），HUI 活动、疼痛、情绪和总体评分的变化具有临床意义。日记的内容显示患者呼吸能力、活动能力、能量、睡眠等方面都有所改善，包括积极的反馈，如：“增加潮气量，呼气减缓”、“我整体感觉良好”和“精力充沛”。
研究结果表明瑜伽具有产生益处的巨大潜力。将在一项全国多地点研究中进一步探讨潜在益处。
