Effects of Respiratory Muscle Training in Patients With Acute Ischemic Stroke

Effects of Respiratory Muscle Training in Patients With Acute Ischemic Stroke

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.

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.
