Purpose : This study investigated the effects of air stacking exercise on respiratory ability of patients with cervical cord injury. Methods : The subjects of this study were 30 patients with cervical cord injury were randomly placed in an experimental group(n=15) and a control group(n=15), respectively. Basic therapeutic exercise(ROM exercise, stretching exercise, strengthening exercise) were conducted twice a day for 30 minutes each time in all subjects and air stacking exercise was additionally conducted on the experimently group only. Air stacking exercise was conducted for 4 weeks, twice a day, 5 times a week and repeated 10 to 15 times each time. Lung capacity, MIC and, peak cough flow were measured and evaluated. Results : The results showed that FEV1, FVC, MIC, UPCF and APCF were significantly increased(p<.05), but FEV1/FVC didn't show the significant differences in an experimental group. In a control group, the findings showed that FEV1, FVC were increased significantly(p<.05) while FEV1/FVC, MIC, UPCF, and APCF didn't show the significant differences.There were significant differences in FEV1, FVC, MIC, and APCF between a experimental group and a control group in the results of Pulmonary Function Test after conducting the pulmonary rehabilitation. However, no significant differences were found in FEV1/FVC, and UPCF between a experimental and a control group(p>.05). Conclusion : air stacking exercise has positive effects on the improvements of cough functions and that of pulmonary functions such as lung volume, lung elasticity in patients with cervical cord injury.

PURPOSE: The aim of this study was to examine the effect of air stacking exercise on lung capacity, activities of daily living, and walking ability in elderly adults. METHODS: A total of 27 subjects were randomly assigned to an experimental group (EG=13) or a control group (CG=14). Subjects in the experimental group participated in an active pulmonary rehabilitation program. 5 days a week for 4 weeks. The active pulmonary rehabilitation program was composed of an air stacking exercise with an oral nasal mask and manually assisted coughing. Conventional pulmonary rehabilitation exercises, such as, cough exercise, deep breathing, and abdominal muscle strengthening exercises were performed by both groups. Pulmonary function parameters, peak cough flow (PCF), and oxygen saturation were measured and the 6-minute walk test and Korean version of the modified Barthel index (K-MBI) scores were applied. RESULTS: Significant intergroup differences were observed for forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) results after intervention (p<.05), and for 6 minute walk test and PCF results after intervention and at 2-week follow-up visits (p<.05). Post hoc test results showed significant differences in K-MBI, 6-minute walk test, and FEV1 in the experimental group after intervention (p<.05). FVC values were significantly higher after intervention and at 2-week follow-up visits versus pre-intervention (p<.05). PCF values were also significantly higher after intervention and remained significantly higher at 2-week follow-up visits (p<.05). CONCLUSION: Air stacking exercise in elderly adults improves lung capacity and exercise tolerance.

Purpose : To compare the immediate effects of air stacking maneuver using resuscitator bags and balloons. Methods : Twenty healthy young adults participated in this study. Forced vital capacity (FVC) and peak cough flow (PCF) tests were performed at pre-intervention, and then, the maximum insufflation capacity (MIC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow (PEF), and peak cough flow (PCF) were measured using the air stacking maneuver via resuscitator bags and balloons. Interventions were randomly performed, and a 40-min break was provided between interventions. The evaluation process in this study was conducted in accordance with the guidelines of the American Thoracic Society (ATS) 2019. To compare the three outcomes measured at pre-and post-interventions, repeated measures analysis of variance was performed. Results : A significant difference was found in the MIC, FEV1, PEF, and PCF after the air stacking maneuver using resuscitator bags and balloons, whereas no significant difference was observed between resuscitator bags and balloons. Conclusion : No significant difference was found in the immediate effect of the air stacking maneuver using resuscitator bags and balloons in this study. Air stacking maneuver using balloons can increase the success rate of the techniques by providing visual feedback on the amount of air insufflation when performed with balloon blowing exercise. Balloons are cheaper and easier to buy compared to manual resuscitator bags; therefore, education on the air stacking maneuver using balloons will have a positive effect on pulmonary rehabilitation.
