Hot issues of traditional Chinese exercises and stroke dysfunction rehabilitation
Aerobic exercise training enhances mobility, mental health, and overall quality of life for stroke patients.The American Heart Association advocates for routine aerobic exercise in both stroke prevention and treatment (10).Research has established that cerebrovascular hemodynamic disorders play a critical role in stroke's pathophysiology (22).Aerobic activities can mitigate or even reverse arterial stiffness by fostering arterial remodeling, reducing sympathetic nervous activity, and enhancing cerebrovascular hemodynamics.A study by Zheng et al. (23) found that a 12-week Tai Chi program offers potential benefits for cerebrovascular hemodynamics in elderly individuals at risk of stroke.Moreover, peak oxygen uptake, a prime measure of aerobic capacity and a key predictor of mortality in cardiovascular disease, is approximately 20% higher in Tai Chi practitioners than in inactive individuals.Long-term Tai Chi practice is associated with improved cardiovascular health and a reduced risk of stroke (24).
Preventing stroke effectively involves managing modifiable risk factors such as hypertension, hyperlipidemia, hyperglycemia, lack of exercise, and obesity, which are more controllable compared to clinical treatment.Hypertension is the primary modifiable risk factor for stroke, with regular physical exercise being a key preventative and therapeutic strategy for hypertension (25).Research indicates that a 12-week Tai Chi training significantly lowers systolic and diastolic blood pressure, aiding in effective blood pressure management (26).Additionally, a long-term Tai Chi practice enhances bone density, serving as a cost-effective approach to osteoporosis prevention (27).By addressing stroke's high-risk factors, traditional Chinese exercises play a vital role in its primary prevention.
Reintegration into society and family is a critical, long-term objective in stroke rehabilitation.However, this reintegration does not signify the end of rehabilitation needs, as ongoing treatment is often required.Continuing rehabilitation at home or in the community is, therefore, crucial.Traditional Chinese exercises, known for their ease of learning, moderate intensity, suitability for various individuals, and independence from economic and locational constraints, facilitate remote rehabilitation via telemedicine platforms.This approach enables innovative rehabilitation, allowing patients to continue their A map of the analysis of keywords.

Traditional Chinese exercises and motor dysfunction in stroke
Balance and coordination dysfunctions are prevalent among stroke patients.Traditional Chinese exercises, characterized by their slow, relaxed, and rhythmic movements, are particularly beneficial for those with motor impairments.These exercises help to strengthen muscles, increase endurance, and improve motor skills and balance (29,30).
Tai Chi, involving exercises such as shifting the center of gravity, trunk rotation, and single-leg standing in various positions, effectively enhances balance and coordination control in these patients (31).The Tai Chi gait, marked by lower impact forces and more balanced weight distribution between the front and rear foot, contributes to a reduced fall risk (32).Research by Tsang et al. (33) demonstrates that Tai Chi practitioners exhibit superior knee joint proprioception and standing balance control compared to controls.Furthermore, studies by Kwok et al. (34) suggest that Tai Chi training enhances hand-eye coordination and balance control, showing increased accuracy in both stationary and moving visual signal tasks.Addressing the risk of falls in subacute stroke patients, research by Zhao et al. (35) has adapted traditional Tai Chi into a seated form, minimizing fall risks while maintaining its rehabilitation efficacy for these patients.
Core muscle group training, commonly employed in clinical balance training, hinges significantly on the role of deep core muscles for trunk stabilization (36).These muscles include the diaphragm, transversus abdominis, and pelvic floor muscles, all of which are central to respiratory functions and trunk control (37).Effective core stability, crucial for correct postural control, is fundamentally linked to proper breathing techniques (38).The Liuzijue, a technique focusing on breath regulation through varying mouth shapes during inhalation and exhalation, facilitates intra-abdominal pressure control.This method activates core muscles and enhances trunk coordination (39).Research by Zhang et al. (40) and Wang et al. (41) indicates that the Liuzijue, integrating breathing-based exercises, is more effective in improving balance function in stroke patients through deep core muscle activation than traditional core stability training.The Baduanjin, involving symmetric postures and coordinated movements, requires patients to shift their center of gravity and control lower limb and trunk movements, thereby extending balance maintenance.Studies by Liao et al. (42) demonstrate that this practice enhances muscle strength, balance, and coordination on the hemiplegic side, aiding in the rehabilitation of affected limb functions.Additionally, the Baduanjin includes exercises targeting joint mobility and body ligaments (43).

Traditional Chinese exercises and respiratory dysfunction in stroke
The Liuzijue technique presents distinct advantages in ameliorating post-stroke dysarthria.Stroke patients with dysarthria maintain basic language skills but struggle with muscle dysfunction affecting articulation, breathing, phonation, rhythm, and resonance (44).Recovery from post-stroke dysarthria heavily relies on improved

Traditional Chinese exercises and cognitive dysfunction in stroke
Research shows that cognitive dysfunction is a common aftermath of stroke, predominantly manifesting as memory impairment, diminished concentration, and reduced executive and computational skills.This cognitive decline significantly hampers the daily living abilities and overall quality of life of stroke survivors (47).Yi Jin Jing, a traditional Chinese exercise, has been found to positively affect both the physical and mental health of these patients.A study by Xue et al. (48) indicates that Yi Jin Jing, when compared to standard rehabilitation therapies, is more effective in enhancing cognitive dysfunction following a stroke.

Traditional Chinese exercises and mental and emotional dysfunction in stroke
Stroke survivors frequently encounter negative emotions, including anxiety, depression, and sorrow.Traditional Chinese exercises encourage a tranquil state of mind and body, emphasizing harmonious breathing for optimal physical and mental relaxation (49).This approach effectively eases sympathetic nervous system tension and enhances mood.Mental relaxation, achieved through these practices, is also associated with reduced fatigue (50).Extensive research confirms that regular Tai Chi practice contributes to better mental health, notably stress reduction, anxiety relief, depression mitigation, and the fostering of positive emotions (51,52).The Baduanjin, integrating physical movements with mental regulation, has been found to improve neurohumoral regulation, bolster immunity, and enhance sleep quality, thereby promoting overall physical well-being in stroke survivors (53).Given that poor sleep quality is a common challenge for stroke patients (54), Tai Chi has been identified as a beneficial practice for improving sleep in individuals with insomnia, positioning it as a viable complementary or alternative therapeutic option (55).

Directions for improvement and challenges
The exploration of traditional Chinese exercise practices in stroke rehabilitation reveals significant opportunities for improvement and further research.A key challenge is the lack of standardized and specific operational guidelines for these methods, affecting their comparability across various studies and clinical settings.Additionally, the field is marked by a scarcity of robust clinical trial designs, particularly concerning long-term follow-up studies, which restricts a comprehensive understanding of the enduring effects of these practices.Given the diverse cultural backgrounds and personal preferences of patients, there is a pressing need for future research to focus more on developing personalized rehabilitation programs.Therefore, future efforts in this domain must be more meticulous and inclusive, aiming to improve the quality of research and effectively address the rehabilitation needs of stroke patients.

Limitations
First, our analysis exclusively considered pertinent literature from the Web of Science database, potentially constraining the scope of the research.Second, the study focused on articles and reviews, omitting conference records, letters, and books, which could introduce biases.Third, the study considered publications in English.However, in non-English-speaking regions, researchers might predominantly explore traditional Chinese exercises.This potential bias warrants attention.Finally, traditional Chinese exercises are profoundly shaped by traditional Chinese philosophical principles and wellness concepts.Diverse regions show varying degrees of acceptance influenced by their unique historical backgrounds and the influence of economic factors.Prosperous regions receive advantages from governmental or societal support, whereas economically disadvantaged areas encounter resource constraints.Furthermore, societal preferences significantly influence the adoption of these exercises.Some prioritize both physical and mental well-being, while others opt for alternative exercise forms and spiritual activities.In conclusion, the varying regional perspectives on the effectiveness of traditional Chinese exercises result from cultural, historical, and economic influences.Analyzing these distinctions can enhance our holistic comprehension of their adaptability, offering insights for promotional and preservation initiatives.Future research should further investigate regional disparities to offer a comprehensive view of the global landscape of traditional exercises within the context of stroke rehabilitation.

Conclusion
Considering the varying location and severity of stroke injuries, it is crucial to tailor and individualize the training of traditional Chinese exercises.In a study conducted by Li et al. (56), it was discovered that personalized therapeutic Tai Chi training was superior to conventional training methods in reducing the occurrence of falls among community-dwelling older adults at a high risk of falls.Moving forward, utilizing contemporary rehabilitation theory to optimize and enhance traditional Chinese exercises is essential.This entails integrating the technical aspects of traditional exercise with the specific features of movement disorders during stroke recovery.Moreover, there is a need to expand the stroke rehabilitation training program and explore innovative approaches to traditional exercise rehabilitation.
In summary, the utilization of traditional Chinese exercises in stroke rehabilitation demonstrates significant potential for advancement.In the future, researchers may prioritize reducing the risk of stroke and implementing effective primary prevention strategies.Despite notable advancements in this field, a review and analysis using CiteSpace software reveals ongoing challenges and obstacles in its future progress.Overcoming these hurdles necessitates sustained innovation and diligent efforts from researchers worldwide.
