Abstract

The purpose of this study was to examine the efficacy of targeted respiratory muscle training in patient with Chronic Obstructive Pulmonary Disease (COPD) . The study was conducted using descriptive-analytic method. The descriptive method would result in information related to any dependent and independent variable. The analytical method of randomized clinical trial based the study of the effect of respiratory muscle training. A random allocation was done resulted in eight patients with COPD belonged the breathing exercise group, eight patients received general exercises reconditioning. The other seven patients with COPD belonged to a control group with no intervention and without random allocation.

The respiration group underwent diaphragmatic breathing exercise + pursed lip breathing (PLB) . Breathing exercise were done daily at home an three times a week, under supervision at the Installation of Rehabilitation Medicine, dr Cipto Mangunkusumo hospital. The reconditioning group received exercises with ergocycle, three times a week which lasted for eight weeks under supervision at the institution.

The method analysis was done as follows : Univariat analysis was conducted to study the frequency characteristic of groups. Bivariat analysis ( paired-t test, Wilcoxon tesr) was conducted to study the effect of intervention.

Result of the study were as follows: The respiration group showed increased expiration muscle strength (MEP) significantly (p<> 0.05) and walking ability increased significantly (p <> 0.05) , physical fitness (VO ₂ max) increased (p> 0/05) . in the control group decrease of respiratory muscle strength was observed almost significantly (p > 0.05). The inspiratory muscle strength did not show result as expected, but decreased insignificantly in both groups with intervention and increased in the control group (p> 0.05).

The conclusion of the study were as follows. Breathing exercises and reconditioning resulted in better quality of life as shown by increase in walking ability . both successes derived of different approaches breathing exercise group by increases of expiratory muscle strength resulted in decrease of dyspnea and increase in quality of life. On the other side , reconditioning group resulted in better physical fitness and to better quality of life . respiratory muscle training was recommended when the exercises were intended to control dyspnea and reconditioning was done and reconditioning was done if physical fitness was intended.

We have to be aware of the increase of airway resistance in the diaphragmatic breathing exercises group + PLB . In the reconditioning group insspite of most decrease of residual air, there were decrease of inspiratory muscle strength.

Key words: Diaphragmatic breathing exercise; PLB (Pursed Lip Breathing)[ MEP (Maximal Expiratory Pressure); MIP (Maximal Inspiratory Pressure) ; dyspnea; VO₂ maximum; 12 minutes walk.
