This study was conducted to evaluate the comparative effect of yogic and conventional treatment in diarrhea-predominant irritable bowel syndrome (IBS) in a randomized control design. The patients were 22 males, aged 20-50 years, with confirmed diagnosis of diarrhea-predominant IBS. The conventional group (n = 12, 1 dropout) was given symptomatic treatment with loperamide 2-6 mg/day for 2 months, and the yogic intervention group (n = 9) consisted of a set of 12 asanas (yogic poses, i.e., Vajrasana, Shashankasana, Ushtrasana, Marjariasana, Padhastasana, Dhanurasana, Trikonasana in two variations, Pawanmuktasana, and Paschimottanasana) along with Surya Nadi pranayama (right-nostril breathing) two times a day for 2 months. All participants were tested at three regular intervals, at the start of study--0 month, 1 month, and 2 months of receiving the intervention--and were investigated for bowel symptoms, autonomic symptoms, autonomic reactivity (battery of five standard tests), surface electrogastrography, anxiety profile by Spielberger's Self Evaluation Questionnaire, which evaluated trait and state anxiety. Two months of both conventional and yogic intervention showed a significant decrease of bowel symptoms and state anxiety. This was accompanied by an increase in electrophysiologically recorded gastric activity in the conventional intervention group and enhanced parasympathetic reactivity, as measured by heart rate parameters, in yogic intervention group. The study indicates a beneficial effect of yogic intervention over conventional treatment in diarrhea-predominant IBS.
本研究采用随机对照设计，旨在评估瑜伽疗法与传统疗法对腹泻型肠易激综合征（IBS）的比较效果。患者为22名年龄在20至50岁之间的男性，确诊为腹泻型IBS。传统治疗组（n = 12，1人退出）给予洛哌丁胺2 - 6毫克/天的对症治疗，为期2个月；瑜伽干预组（n = 9）则进行一组12种体式（瑜伽姿势，即金刚坐、兔子式、骆驼式、猫式、站立前屈式、弓式、两种变体的三角式、风箱式和坐立前屈式）的练习，并配合太阳神经呼吸法（右鼻孔呼吸），每天两次，为期2个月。所有参与者在研究开始时（0个月）、接受干预1个月和2个月时，每隔一段时间进行一次测试，并对肠道症状、自主神经症状、自主神经反应性（五项标准测试组合）、体表胃电图、通过斯皮尔伯格自评问卷评估的焦虑状况进行调查，该问卷评估特质焦虑和状态焦虑。两个月的传统治疗和瑜伽干预均使肠道症状和状态焦虑显著减轻。传统治疗组伴有电生理记录的胃活动增加，而瑜伽干预组则表现为副交感神经反应性增强，通过心率参数测量。该研究表明，在腹泻型IBS中，瑜伽干预比传统治疗具有更好的效果。
