Effects of Pulmonary Rehabilitation on Respiratory Muscle Strength and Functional Capacity of Individuals with Chronic Obstructive Pulmonary Disease: Case Report

Abstract

Chronic obstructive pulmonary disease is a common preventable and treatable disease characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases. The objective of this study was to evaluate the effects of a pulmonary rehabilitation program on respiratory muscle strength and functional capacity of individuals with chronic obstructive pulmonary disease. An elderly male patient participated in the pulmonary rehabilitation program and was evaluated before and after intervention. This program consisted of four phases: stretching, aerobic exercises, resistance training and relaxation.  The physical activities were provided three times a week on alternate days, for 4 months, totaling 48 sessions. The results obtained after the rehabilitation program showed improvement in the physical functional capacity of the patient measured by the six-minute walk test (Pre=480; Post=540m). The maximal inspiratory pressure values increased (Pre=-60; Post=-120cmH₂O) whereas the maximal expiratory pressure values remained the same (Pre=50; Post=50cmH₂O). Therefore, the respiratory rehabilitation program has improved functional capacity and inspiratory muscle strength.
