Background Balance dysfunction is the main manifestation of patients after stroke in clinic, which leads to unstable gait and seriously affects the prognosis of patients. The first prerequisite to improve the balance dysfunction is to increase the exercise of lower limbs. Previous clinical studies have found that besides Chinese traditional Tai Ji training, inspiratory muscle training can enhance the intra-abdominal pressure, promote the stability of spine and pelvis, and improve the balance function of patients by enhancing their cardiopulmonary function. However, it still needs further proof from large sample research. The overall goal of this experiment is to further evaluate the clinical effect of inspiratory muscle training combined with Tai Ji to further improve the balance function of patients after stroke. Methods/design This trial is a randomized controlled trial, which will compare the superiority of Tai Ji training and inspiratory muscle combined with Tai Ji training in improving the balance function of stroke patients. Patients are randomly divided into two groups, namely Tai Ji group and inspiratory muscle training group. Recruit 62 inpatients with stroke who meet the test criteria, and observe the improvement of balance function after 4 weeks of intervention. The first evaluation index is American balance manager balance test system. The second evaluation index is diaphragm ultrasound, berg balance scale and trunk injury scale.
Discussion: To evaluate the efficacy of inspiratory muscle training combined with Tai Ji in improving balance function of patients after stroke. The results of this study will provide more evidence for the clinical application of this therapy in the future.
