Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Dofin Breathing Strength Builder

Usual post stroke care and respiratory muscle training

Group Type EXPERIMENTAL

Dofin Breathing Strength Builder

Intervention Type DEVICE

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.

Usual post stroke care
