Our previous studies demonstrated that the regular practice of recumbent isometric yoga reduced the fatigue of patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Some patients with ME/CFS have postural orthostatic tachycardia syndrome (POTS); however, the effects of recumbent isometric yoga on orthostatic cardiovascular responses and whether recumbent isometric yoga improves POTS remain unknown. This pilot study was done to investigate the effect of recumbent isometric yoga on the orthostatic cardiovascular response of patients with ME/CFS.
Ten adult female patients with ME/CFS performed recumbent isometric yoga for 12 weeks. Changes in their systolic blood pressure (SBP), diastolic blood pressure (DBP), and the pulse rate (PR) during an active standing test were compared before and after the 12-week regimen. Among the 10 patients, 8 manifested a normal orthostatic response and 2 manifested POTS before the yoga intervention. Patients who manifested a normal orthostatic response before yoga also manifested the normal orthostatic pattern after the yoga intervention. In contrast, the two patients who manifested POTS before the regimen showed a normal orthostatic response after completing the yoga intervention.
This study found that the patients who manifested POTS and performed recumbent isometric yoga for 12 weeks had a reduced increase in PR after standing up. This pilot study suggests that recumbent isometric yoga would be useful as an adjunctive nonpharmacological intervention for improving POTS in patients with ME/CFS. This finding should be confirmed in a larger number of cases.
我们之前的研究表明，定期进行仰卧等长瑜伽可减轻肌痛性脑脊髓炎/慢性疲劳综合征（ME/CFS）患者的疲劳感。一些ME/CFS患者患有体位性直立性心动过速综合征（POTS）；然而，仰卧等长瑜伽对直立心血管反应的影响以及仰卧等长瑜伽是否能改善POTS尚不清楚。本初步研究旨在调查仰卧等长瑜伽对ME/CFS患者直立心血管反应的影响。
10名成年女性ME/CFS患者进行了12周的仰卧等长瑜伽练习。比较了她们在12周训练前后主动站立测试期间的收缩压（SBP）、舒张压（DBP）和脉搏率（PR）变化。在这10名患者中，8名在瑜伽干预前表现出正常的直立反应，2名表现为POTS。瑜伽干预前表现出正常直立反应的患者在干预后也表现出正常的直立模式。相比之下，两名在训练前表现为POTS的患者在完成瑜伽干预后表现出正常的直立反应。
本研究发现，表现为POTS并进行12周仰卧等长瑜伽练习的患者站立后PR升高幅度减小。这项初步研究表明，仰卧等长瑜伽作为一种辅助非药物干预措施，可能有助于改善ME/CFS患者的POTS。这一发现应在更多病例中得到证实。
