| dc.title | The effects of yoga on physical functioning and sleep quality among women with breast cancer | en_US |
| dcterms.abstract | Background | en_US |
| dcterms.abstract | Upper limb complications and sleep disturbances are prevalent, persistent, and serious health problems in women with breast cancer. However, these problems are underrecognized in clinical practice and thus have substantial adverse impacts on the health and quality of life of women with breast cancer. As yoga practices have been shown to improve physical and psychological health in people with cancer, such practices may also alleviate upper limb complications and sleep disturbances in women with breast cancer. The aim of this study is to evaluate the ability of yoga therapy to improve the upper limb function and sleep quality of women with breast cancer. | en_US |
| dcterms.abstract | Methods | en_US |
| dcterms.abstract | This study was performed in two phases. In phase 1, two cross-sectional studies were conducted. The first study compared the physical, physiological, and psychosocial health conditions of women with and without breast cancer. This study provided findings for understanding the health status of breast cancer women and provided insights into the design and development of rehabilitation for breast cancer women. The second study compared the physical, physiological, and psychosocial health conditions of women with and without experience of practicing yoga. This study enhanced the understanding of the potential health benefits of yoga practice and provided insights into the integration of yoga into clinical practice. | en_US |
| dcterms.abstract | In phase 2, a pilot randomized controlled trial (RCT) was conducted to examine the effects of tailor-made yoga therapy on upper limb function and sleep quality in women with breast cancer. The participants were randomly allocated in a 1:1 ratio into one of two parallel groups: the intervention group and the control group. The intervention group received eight weekly 60-min group-based yoga interventions instructed by a certified yoga teacher, and the control group received no active treatment and attended the yoga program after the final measurements. The participants were assessed before the intervention, in the middle of the intervention (after four treatment sessions), and immediately after and 1 month after the intervention. The primary outcome measures were upper limb function and sleep quality. The secondary outcome measures were shoulder mobility and upper limb muscle strength, cardiovascular responses, level of anxiety and depression, level of fatigue, and health-related quality of life. | en_US |
| dcterms.abstract | Results | en_US |
| dcterms.abstract | Women with breast cancer have poorer health status than those without breast cancer, including physical health conditions (upper arm motor function, and exercise endurance), physiological health conditions (heart rate variability [HRV]), and psychosocial health conditions (subjective sleep quality, level of anxiety and depression, and fatigue, and health-related quality of health). On the other hand, long-term female yoga practitioners outperformed those healthy women without experience of yoga practice in terms of upper limb muscle strength and mobility (especially non-dominant side), HRV, sleep latency, and anxiety. | en_US |
| dcterms.abstract | The pilot RCT revealed that breast cancer participants in the yoga group demonstrated significantly shorter sleep latency and less sleep disturbance than the control group at post-intervention and at 1-month follow-up, respectively. Further, the yoga group demonstrated significantly improved shoulder mobility and muscle strength, and arm symptoms (subscale of FACT-B) than the control group from mid-intervention until 1-month follow-up. In addition, the yoga group demonstrated significant improvement in upper limb function, sleep quality, exercise endurance, anxiety, and health-related quality of life across time. In contrast, there was no such significant changes in the control group over time. | en_US |
| dcterms.abstract | Conclusions | en_US |
| dcterms.abstract | Yoga, a mind-body practice, seems to be a form of supportive care that simultaneously enhances physical, physiological, and psychological health conditions among women with breast cancer. These promising results of this study demonstrated that our tailor-made yoga program is an intervention that could be integrated into clinical practice. | en_US |
