Introduction: Chronic obstructive pulmonary disease is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways to noxious particles or gases. Exacerbations and co morbidities contribute to the overall severity in individual patients [1]. In India, according to National Commission on Macroeconomics and Health background paper by Murthy et al., the annual treatment costs for COPD had been estimated to be greater than Rs. 35,000 crores in 2011 and Rs. 48,000 crores in 2016 [3]. COPD produces obstruction to the airflow which affects both the mechanical function and gas exchange of the lung. Respiratory muscles must work harder to overcome this resistance and therefore it leads to weakness of the respiratorymuscles. Drug therapy is the main treatment in patients with COPD which includes bronchodilators, mucolytics, appropriate antibiotics and corticosteroids. Following drug therapy, physical rehabilitation is the only management which reduce dyspnea [4]. Resistive Inspiratory Devices are hand-held devices of varying diameter. The resistance is increased by decreasing the diameter of the devices and resistance is decreased by increasing the diameter of the devices airway [7]. Aims and Objectives of the Study: To compare the effectiveness of Incentive Spirometer and Inspiratory muscles trainer on ventilatory muscle strength on patients with COPD. Methods: Thirty subject male or female with COPD aged between 40-80 years were selected according to convenience (purposive) sampling based on the selection criteria. Subjects were are randomly assigned into two group of 15 subjects each namely experimental Group A and control Group B. Group A was treated with Inspiratory muscles trainer and Group B with Incentive spirometer for a duration of 4 weeks. Discussion: In this study, efforts were made to compare the effects of Incentive Spirometer and Inspiratory muscles trainer devices as a treatment for improving ventilatory muscle strength in patients with mild to severe dyspnea in COPD. The study was done on randomized 30 COPD patients with mild to moderate dyspnea diagnosed by physician. The patients were randomly divided into 2 groups consisting of 15 subjects each. Group A was treated with Inspiratory muscles trainer and Group B with Incentive spirometer for a duration of 4 weeks. The results demonstrated that the patients treated with both the intervention were highly significant in improving ventilatory muscle strength and hence decreasing the exertional dyspnea. However statistically there was significant difference between the two groups. Conclusion: This study provided evidence to support the use of Incentive Spirometer and Resistive Inspiratory Devices to improve ventilatory muscle strength in patients with mild to severe dyspnea in COPD. In conclusion, both the treatment programs are inspiratory muscles trainer is more effective the incentive spirometer in improving Inspiratory Capacity and reducing dyspnea which could be due to improvement in ventilatory muscle strength.
