Effects of Respiratory Muscle Activity in Stroke Patients after Feedback Breathing Exercise

Abstract

and decrease involuntary respira -tion, triggering changes inrespiratory adjustment(1)and decrease inmovement of the thoracic wall and inelectric activity directly or indirectly affects pul-monary function. Therefore, respiratory efficiencyand changes inrespiratory mechanism of patientsreflect damage and asymmetry of thoracic wallmovement and muscular paralysis. In order toresolve these problems, chest wall expansion andventilation and pulmonary volume and capacityshould be appropriately maintained(2) and evaluationof functional ability of the lungs through precisemeasurement of pulmonary functions, and diagnosis,prognosis, and degree of a disease may be made toobtain the ground for exercise prescription(3). Therehave been diverse previous studies of exercises toimprove respiratory function: a study of respiratoryfunction through a long term use of positive expira -tory pressure mask and flutter treatment in cysticfibrosis patients(4), a study of respiratory muscleactivity through diaphragmatic respiration exercisein chronic obstructive pulmonary disease(COPD)patients(5), a study of abdominal muscle activitythrough respiratory muscle exercise in quadriplegiapatients(6), and a study of abdominal respiratorymuscle activation in muscle dystrophy patients(7),and a study of expiratory muscle activation throughexpiratory muscle strengthening exercise in multiplesclerosis patients(8).Thus far studies of respiratory exercise have con -cerned respiratory muscle activity, superficial respi-ratory movement largely in patients with respiratory
