Since falls may lead to fractures and have serious, potentially fatal outcomes, prevention of falls is an urgent public health issue. We examined the effects of chair yoga therapy on physical fitness among psychiatric patients in order to reduce the risk of falls, which has not been previously reported in the literature.
In this 12-week single-blind randomized controlled trial with a 6-week follow-up, inpatients with mixed psychiatric diagnoses were randomly assigned to either chair yoga therapy in addition to ongoing treatment, or treatment-as-usual. Chair yoga therapy was conducted as twice-weekly 20-min sessions over 12 weeks. Assessments included anteflexion in sitting, degree of muscle strength, and Modified Falls Efficacy Scale (MFES) as well as QOL, psychopathology and functioning.
Fifty-six inpatients participated in this study (36 men; mean ± SD age, 55.3 ± 13.7 years; schizophrenia 87.5%). In the chair yoga group, significant improvements were observed in flexibility, hand-grip, lower limb muscle endurance, and MFES at week 12 (mean ± SD: 55.1 ± 16.6 to 67.2 ± 14.0 cm, 23.6 ± 10.6 to 26.8 ± 9.7 kg, 4.9 ± 4.0 to 7.0 ± 3.9 kg, and 114.9 ± 29.2 to 134.1 ± 11.6, respectively). Additionally, these improvements were observable six weeks after the intervention was over. The QOL-VAS improved in the intervention group while no differences were noted in psychopathology and functioning between the groups. The intervention appeared to be highly tolerable without any notable adverse effects.
The results indicated sustainable effects of 20-min, 12-week, 24-session chair yoga therapy on physical fitness. Chair yoga therapy may contribute to reduce the risk of falls and their unwanted consequences in psychiatric patients.
由于跌倒可能导致骨折，并产生严重的、潜在致命的后果，因此预防跌倒成为了一个紧迫的公共卫生问题。我们研究了椅子瑜伽疗法对精神科患者身体适应能力的影响，以期降低跌倒风险，而这一点在文献中尚未有报道。
这是一项为期 12 周的单盲随机对照试验，其中包括 6 周的随访。将混合精神诊断的住院患者随机分配至椅子瑜伽治疗组（在接受现有治疗的基础上进行每周两次、每次 20 分钟的 12 周椅子瑜伽治疗）或常规治疗组。评估包括坐前屈、肌肉力量程度、改良跌倒效能量表（MFES）以及生活质量、精神病理学和功能。
本研究共纳入 56 名住院患者（男 36 名；平均年龄 55.3 ± 13.7 岁；精神分裂症患者 87.5%）。在椅子瑜伽组中，患者的灵活性、握力、下肢肌肉耐力和 MFES 在第 12 周（分别为：55.1 ± 16.6 至 67.2 ± 14.0cm、23.6 ± 10.6 至 26.8 ± 9.7kg、4.9 ± 4.0 至 7.0 ± 3.9kg、114.9 ± 29.2 至 134.1 ± 11.6）均有显著改善，且干预结束 6 周后仍可观察到这些改善。干预组的生活质量视觉模拟量表（VAS）评分有所提高，而两组的精神病理学和功能评分无显著差异。该干预方法似乎具有较高的耐受性，没有明显的不良反应。
20 分钟、12 周、24 次椅子瑜伽治疗对身体适应能力具有可持续的效果。椅子瑜伽疗法可能有助于降低精神科患者跌倒风险及其不良后果。
