Stroke Survivors' Feelings and Perceptions of Their Recovery After a Tai Chi Exercise Intervention: A Qualitative Descriptive Study

Effects of mind-body exercise on physical and psychosocial well-being of stroke patients: A systematic review and network meta-analysis

This study conducted pairwise and network meta-analysis to evaluate the effectiveness of three mind-body exercise interventions (Tai Chi, Qigong, and yoga) on physical capacity, psychological well-being, and quality of life in stroke patients. The research encompassed 30 studies involving 2107 participants and utilized the Risk of Bias 2.0 tool for quality assessment. Pairwise analysis revealed that all three mind-body exercises significantly enhanced patients' quality of life. Tai Chi demonstrated the most comprehensive improvements in balance, limb motor function, activities of daily living, and depression. Network meta-analysis indicated that Qigong was the most effective in improving balance and quality of life for post-stroke patients, followed by Tai Chi. These findings underscore the positive impact of mind-body exercises on both physical and psychosocial outcomes in stroke patients. However, further research involving rigorously designed and adequately powered trials is necessary to enhance the level of evidence in this area.

Stroke Survivors' Personal Efficacy Beliefs and Outcome Expectations of Tai Chi Exercise: A Qualitative Descriptive Study

Prior qualitative research conducted among stroke survivors to explore the potential benefits and challenges of participating in tai chi exercise during stroke recovery is limited to those without depression. A qualitative descriptive approach was used. Social Cognitive Theory and Complex Systems Biology provided the theoretical framework, with focus group interview data collected from stroke survivors after participation in a tai chi intervention. Due to COVID-19, the focus group interview was conducted via online video conferencing. Content analysis of the de-identified transcript was conducted with a-priori codes based on the theoretical framework and inductive codes that were added during the analysis process. Lincoln and Guba's criteria were followed to ensure trustworthiness of the data. Community-dwelling stroke survivors (n = 7) participating in the focus group interviews were on average 68 years old, mainly retired (71%, n = 5), married women (57%, n = 4) with >13 years education (86%, n = 6). The three major themes were: personal efficacy beliefs, tai chi intervention active ingredients, and outcome expectations. Social Cognitive Theory underscored stroke survivors' personal efficacy beliefs, behavior, and outcome expectations, while Complex Systems Biology highlighted the active ingredients of the tai chi intervention they experienced. Participation in the 8-week tai chi intervention led to perceived physical, mental, and social benefits post stroke.

The Feasibility of Tai Chi Exercise as a Beneficial Mind-Body Intervention in a Group of Community-Dwelling Stroke Survivors with Symptoms of Depression

Depression is prevalent among one-third to two-thirds of acute and chronic stroke survivors. Despite the availability of pharmacotherapies and/or psychotherapies, depression persists, even for 5–10 years after stroke, reflecting limited treatment responses and/or adherence to this conventional care. Mind-body interventions are commonly used among adults to ameliorate depressive symptoms. Thus, the feasibility of Tai Chi, alongside conventional care, to manage poststroke depression was investigated using a single-group pre-post intervention design. Recruitment and retention, intervention adherence, safety, acceptability, and fidelity were assessed. Symptoms of depression, anxiety, and stress were assessed using standardized questionnaires, objective sleep was assessed via a research-grade triaxial accelerometer, and blood samples were taken to measure oxidative stress, inflammatory markers, and a neurotrophic growth factor using commercially available kits per manufacturer's protocol. Pre-post intervention changes were assessed using paired t-tests. We enrolled stroke survivors (N = 11, mean age = 69.7 ± 9.3) reporting depression symptoms. After the intervention, we observed significant reductions in symptoms of depression (−5.3 ± 5.9, p=0.01), anxiety (−2.2 ± 2.4, p=0.01), and stress (−4.6 ± 4.8, p=0.01), along with better sleep efficiency (+1.8 ± 1.8, p=0.01), less wakefulness after sleep onset (−9.3 ± 11.6, p=0.04), and less time awake (−9.3 ± 11.6, p=0.04). There was a 36% decrease in oxidative stress (p=0.02), though no significant changes in the other biomarkers were found (all p values >0.05). Tai Chi exercise is a feasible intervention that can be used alongside conventional care to manage poststroke depression, aid in reducing symptoms of anxiety and stress, and improve sleep.
