Objective To determine the effectiveness of adding inspiratory muscle training (IMT) alongside a pulmonary rehabilitation protocol in terms of inspiratory muscle strength, lung function, and exercise capacity in burned adults.
Methods A randomized, double-blinded, sham-controlled study. Fifty-two adult patients with burn injuries, more than 20 years old and at least 20% total body surface area, were assigned randomly either to the experimental or the conventional group. The participants in the experimental group were given IMT plus a pulmonary rehabilitation program; the conventional group received only a pulmonary rehabilitation program. The interventions were performed for 8 weeks. At the beginning and after 8 weeks of training, the respiratory muscles’ strength, lung function and exercise capacity were all examined.
Results After 2 months of training, the experimental group demonstrated statistically significant improvements than conventional group in maximum inspiratory pressure, maximum expiratory pressure, 6-minute walk test, forced vital capacity, and forced expiratory volume in 1 second (p<0.05).
Conclusion An 8-week IMT program coupled with pulmonary rehabilitation increases respiratory muscle strength, pulmonary functions, and functional capacity in burn patients. IMT is a beneficial and efficient therapy that can be easily implemented for burn patients.
To determine the effect of inspiratory muscle training (IMT) on pulmonary function, respiratory muscle strength (RMS), and functional capacity in patients undergoing cardiac surgery. The PubMed, PEDro, CINAHL, Web of Science, CENTRAL, and EMBASE databases were searched from inception to June 2020. Randomized controlled trials (RCTs) that evaluated patients who underwent cardiac surgery were included in this review. Meta-analysis performed using a random-effects model showed that the mean difference in forced vital capacity, forced expiratory volume in 1 second, 6-minute walk distance, and RMS was 3.47% (95% confidence interval [CI], 0.57 to 6.36), 5.80% (95% CI, 2.03 to 9.56), 78.05 m (95% CI, 60.92 to 95.18), and 4.8 cmH2O (95% CI, -4.00 to 13.4), respectively. There is strong evidence that IMT improves inspiratory muscle strength, pulmonary function, and functional capacity, and reduces the length of hospital stay in patients undergoing cardiac surgery.

Objective To determine the effect of respiratory muscle training in patients with chronic obstructive pulmonary disease (COPD) by pulmonary function test and fluoroscopy- guided diaphragm movement. Method: The respiratory muscle training program included breathing retraining, self-exercise and electromyography- assisted biofeedback therapy. 22 COPD patients underwent training program for 177±47.8 (84∼259) days and were followed up regularly. To evaluate the effect of respiratory muscle training, we tested pulmonary function test before and after training. We also evaluated difference of area at full inspiratory and full expiratory time by fluoroscopy- guided diaphragm motion. Results: Parameters in pulmonary function test showed no significant differences before and after respiratory muscle training. In fluoroscopic examination, the difference in the diaphragm movement area at full inspiration and expiration time showed significant improvement after respiratory muscle training (p＜0.05). Conclusion: Diaphragm movement increased in patients with COPD after respiratory muscle training, although pulmonary function test did not. (J Korean Acad Rehab Med 2008; 32: 333-339)
