子午流注指导下练习瑜伽改善肾虚症状的试验研究

Effectiveness of Yoga Practice Guided by Midnight-noon Ebb-flow Theory on Improving Kidney Deficiency Symptoms

【目的】评价子午流注指导下练习瑜伽对改善肾虚症状的有效性。【方法】采用单盲对照试验方法,共纳入21例肾虚证者,分为试验组10例和对照组11例。对照组脱落1例,最终试验组为10例,对照组为10例。试验组于肾经时间北京时间18∶25-19∶25(广州地方时酉时)练习瑜伽,对照组于非肾经时间10∶00—11∶00练习相同的内容。课程形式为阴瑜伽和流瑜伽。试验期为1个月。【结果】(1)试验组总有效率为80.0%,对照组为60.0%,2组比较差异无统计学意义(P>0.05)。(2)练习瑜伽后,试验组肾阴虚腰膝酸软、五心烦热和肾阳虚腰膝酸软、气促等症候有明显改善,与练习瑜伽前比较差异有统计学意义(P<0.05);对照组除夜尿频多有明显改善(P<0.05)外,其他肾虚症候积分与练习瑜伽前比较,差异无统计学意义(P>0.05);2组练习瑜伽后比较,差异均无统计学意义(P>0.05)。(3)在练习瑜伽过程中,2组均未出现明显的不良反应。【结论】在酉时练习刺激肾经的瑜伽体位,其改善肾虚症状的效果具有优于在其他时间练习同样瑜伽体位的趋势,但是子午流注指导下练习瑜伽改善肾虚症状的有效性尚不具有统计学意义。

Objective To evaluate the effectiveness of yoga practice guided by Ziwuliuzhu （midnight-noon ebb-flow） theory on improving the symptoms of kidney deficiency. Methods A single-blind controlled clinical trial was carried out in 21 kidney deficiency patients. The patients were divided into two groups, 10 cases in the treatment group and 11 in the control group. During the experiment, one case of the control group dropped out. The patients in the treatment group took yogo practice （ including yin yogo and flow yogo） at Beijing time 18∶25-19∶25, a period of Youshi for kidney meridian in Guangzhou area, and the patients in the control group took the same yogo practice at Beijing time 10∶00-11∶00. The practice lasted one month. Results （ 1） The total effective rate of treatment group was 80.0% and that of control group was 60.0%, the difference being insignificant between the two trail groups （ P〉0.05）. （ 2） After practice, kidney-yin deficiency symptoms of aching and weakness of waist and knees, feverish sensation over five centers, and kidney-yang deficiency symptoms of aching and weakness of waist and knees, and short breath were much relieved in the treatment group （ P0.05）. （ 3） No obvious adverse reaction was found in the two groups during practice. Conclusion Compared with other period, yogo practice （ practice position for stimulating kidney meridian） at Youshi period shows better effectiveness on kidney deficiency symptoms, but there are insignificant differences of the effectiveness of yoga practice guided by Ziwuliuzhu theory on improving the symptoms of kidney deficiency.
