Brief summary
After acute ischemic stroke, the muscle strength of the limbs of the patients will decrease. Moreover, the respiratory muscles may also be affected. The respiratory muscle training may improve the respiratory recovery and prevent pulmonary complication.
Detailed description
After acute ischemic stroke, the muscle strength of the limbs of the patients will decrease. Moreover, the respiratory muscles may also be affected. The worsening of the respiratory function is weakened and lung function declines, leading to dysfunction of expectoration and swallowing, and increasing the incidence of pneumonia after stroke. In addition, it will also lead to a decline in activity ability, which in turn affects the quality of life. The respiratory muscle training may improve the respiratory recovery and prevent pulmonary complication.
Interventions
DEVICEDofin Breathing Strength Builder
If the patient's condition is stable, respiratory muscle training will be performed under Dofin Breathing Strength Builder 7 days after stroke. The patient will receive respiratory muscle training by repetition of 30 times, two courses per day, x 7 days, for three weeks. The initial load was set at 30% of the participants' maximal baseline strength and increased weekly at intervals of 2 cmH2O.

| Swallowing.1 | Baseline | Swallowing function assessed by the Functional Oral Intake Scale (FOIS). The score can go from 1-7, 7 is the better oral intake condition. |
| Swallowing.2 | Within one week after training | Swallowing function assessed by the Functional Oral Intake Scale (FOIS). The score can go from 1-7, 7 is the better oral intake condition. |
| Swallowing.3 | Twelve weeks after training | Swallowing function assessed by the Functional Oral Intake Scale (FOIS). The score can go from 1-7, 7 is the better oral intake condition. |
| Life quality.2 | Within one week after training | Quality of life assessed by Short-form 12 (SF-12). SF-12 can go from 0-100, 100 is the better life quality. |
| Dyspnea.2 | Within one week after training | Dyspnea assessed by Modified Borg Dyspnea Scale (MBS). MBS can go from 0-10, 10 is the more severe condition. |
| Dyspnea.3 | Twelve weeks after training | Dyspnea assessed by Modified Borg Dyspnea Scale (MBS). MBS can go from 0-10, 10 is the more severe condition. |
