The purpose of this study was to examine the effects of combined respiratory physical therapy on respiratory function, spinal curve and spinal mobility for community-dwelling elderlies with restrictive lung diseases. In total, 10 patients participated in an 8-week intervention program of thoracic cage mobilization and breathing exercise in combination. The results of the study are as follows: for respiratory function, the forced expiratory volume in 1 second (FEV1), forced vital capacity(FVC), and FEV1/FVC were significantly improved to $.30{\pm}0.31{\ell}$, $.46{\pm}.42{\ell}$, and $18.10{\pm}11.39%$, respectively (p<.05). For spinal curve, the thoracic curve and the lumbar curve were improved significantly to $-2.20{\pm}1.40^{\circ}$ and $-1.20{\pm}1.14^{\circ}$, respectively (p<.01). For spinal mobility, the thoracic flexion ($3.40{\pm}2.99^{\circ}$), thoracic extension ($3.50{\pm}1.43^{\circ}$), lumbar flexion ($4.50{\pm}4.74^{\circ}$), and lumbar extension($-1.50{\pm}1.84^{\circ}$) were all significantly improved (p<.05). These findings indicate that thoracic cage mobilization and breathing exercise in combination improve the respiratory function, spinal alignment, and spinal mobility in elderly people with restrictive lung diseases.

Background: Breastfeeding reportedly reduces the overall frequency of infections. Respiratory syncytial virus (RSV), the most common respiratory pathogen in infants, involves recurrent wheezing and has a pathogenic mechanism related to airway structural damage. Purpose: This study aimed to investigate whether breastfeeding has a beneficial effect against RSV-induced respiratory infection compared to formula feeding among infants in Korea. Methods: We retrospectively reviewed the medical records of infants under 1 year of age who were admitted with RSV infection between January 2016 and February 2018 at the department of pediatrics of 4 hospitals. We investigated the differences in clinical parameters such as cyanosis, chest retraction, combined infection, fever duration, oxygen use, oxygen therapy duration, intensive care unit (ICU) admission, and corticosteroid treatment of exclusive breast milk feeding (BMF), artificial milk formula fed (AMF), and mixed feeding (MF) groups. Results: Among the 411 infants included in our study, 94, 161, and 156 were included in the BMF, MF, and AMF groups, respectively. The rates of oxygen therapy were significantly different among the BMF (4.3%), MF (8.1%), and AMF (13.5 %) groups (P=0.042). The odds ratios (ORs) for oxygen therapy was significantly higher in the AMF group than in the BMF group (adjusted OR, 3.807; 95% confidence interval, 1.22-11.90; P=0.021). The ICU admission rate of the BMF group (1.1%) was lower than that of the MF (3.5%) and AMF (4.5%) groups; however, the dissimilarity was not statistically significant (P=0.338). Conclusion: The severity of RSV infection requiring oxygen therapy was lower in the BMF than the AMF group. This protective role of human milk on RSV infection might decrease the need for oxygen therapy suggesting less airway damage.

The purpose of this study was to identify the differences in pulmonary functioning after respiratory exercise with IPPB (Intermittent Positive Pressure Breather) in patients with progressive muscular dystrophy (PMD). The subjects were 46 patients with PMD who were admitted to the Rehabilitation Medicine Department of Youngdong Severance Hospital. The subjects were assigned into one of 2 groups. The control group received comprehensive treatments such as ROM exercise, deep breathing exercise, moist hot packs, and ultrasound twice a day while admitted at the Rehabilitation Medicine Department. Unlike the control group, the subjects at the experimental group received respiratory exercise treatment with IPPB. The subjects were admitted for 10~19 days, and the average length of hospital stay was 12.2 days. Pulmonary functioning was evaluated at admission and discharge by SENSOR MEDICS. The data were analyzed by a paired t-test and a independent t-test. The results were as follows: 1) The change of each parameter of pulmonary function tests were significantly improved in all groups after respiratory exercise treatment during admission (p<0.05). 2) By comparing the change of each parameter of pulmonary function tests between the experimental group and control group, the parameters of vital capacity (VC), forced vital capacity, forced vital capacity predicted (FVCP) and forced expiratory volume in 1 second (FEV1) were significantly improved in the experimental group which had received the pulmonary exercise treatment with IPPB (p<0.05). In conclusion, this study suggests that the pulmonary exercise treatments with IPPB facilitated improvement in the pulmonary functioning for the PMD patients during their hospital stay.

Background: Posterior-anterior (PA) vertebral mobilization, a manual therapy technique has been used for relieving pain or stiffness treating in spinal segment for in clinical practice, however evidence to gauge efficacy is yet to be synthesised. Objects: This study aimed to investigate the effect of PA mobilization of the thoracic spine on the respiratory function in patients with low back pain (LBP). Methods: The study participants included 30 patients with chronic LBP. They were randomly allocated to the experimental and control groups. The experimental and control groups received PA mobilization of the T1-T8 level of the thoracic spine and placebo mobilization, respectively. All patients received interventions for 35 minutes a day, five times a week, over 2-week period, respectively. Forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), peak expiratory flow (PEF), forced expiratory flow 25~75% ($FEF_{25{\sim}75%}$), and chest wall expansion were measured before and after the intervention. Statistical analysis was performed using independent t-test and two-way analysis of variance, and Pearson's correlation analysis was used to compare the correlation between respiratory function and chest measurement. Results: The experimental group showed significant improvements in FVC, $FEV_1$, PEF, $FEF_{25{\sim}75%}$ (p<.05), and chest wall expansion (p<.05) compared with the control group. Conclusion: PA mobilization of the upper thoracic spine may be beneficial for improving respiratory function parameters including FVC, $FEV_1$, PEF, $FEF_{25{\sim}75%}$, and chest wall expansion in patients with chronic LBP.

Background: The purpose of this study was to investigated the effects of threshold resistance inspiratory muscle training on respiratory function in chronic stroke patients. Design: Randomized Controlled Trial Methods: Eighteen patient with stroke were randomly assigned to the experimental group (n=9) and control group (n=9) all testing and training. The experimental group underwent threshold resistance inspiratory muscle training with resistance adjusted of maximal inspiratory pressure, 60 breathing a day and general physical therapy 30 minutes a day, 5 times a week for 4 weeks. The control group was taken general respiratory muscle training and general physical therapy for 4 weeks in the same way. Respiratory function, walking ability were evaluated before and after the intervention. Statistical significance of the results were evaluated by ANCOVA between control group and experimental group after intervention. Results: There was a significant increase in FVC and FEV1 in the experimental group in pulmonary function tests (p<0.05). There was a significant difference with the maximum inspiratory pressure and the maximum inspiratory flow rate between experimental and control group (p<0.05). There was no significant difference with the maximum inspiratory capacity between experimental and control group (p>0.05) but the maximum inspiratory capacity of experimental group some increased than that of control group. Conclusion: These finding gave some indications that the threshold resistance inspiratory training may benefit on pulmonary function in people with stroke, and it is feasible to be included in rehabilitation interventions with this population.

The purpose of this study was to examine the effect of kinematic taping on respiratory muscle strength in smokers. Twenty - five university students who smoke were involved in the study. All participants were applied to kinematic taping to breathe deeply again. Subjects sit on their backs straight up and place their hands on their thighs. Tape 1 is applied from the lower prominent neck vertebrae(seven cervical vertebra) inward and downward, past shoulder blade, around ribs to the lower tip of sternum. Tape 2 extends to the lower, outer edge of shoulder blade, around ribs to the lower tip of sternum. Respiratory muscle strength was measured with Micro Mouth Pressure Measurement before and after taping. The application of kinematic taping significantly improved the inspiratory and expiratory muscle strength (p<.05). These findings suggest that kinematic taping effective in improving respiratory muscle strength and deep breathing.

PURPOSE: The purpose of this study was to identify the effect of abdominal stabilization exercise with Stabilizer and Gymball. METHODS: The participants were divided randomly into 2 groups each of 20 participants in the gymball exercise group and 20 participants in the exercise group. The changes of respiratory muscle activity between the two groups were measured three times a week for 4 weeks. The activity of rectus abdominis and internal oblique was measured using surface EMG to measure respiratory muscle activity. The training was repeated five sets, and one set was repeated 6 times with one 10 second exercise and 5 second rest. RESULTS: The results of the study showed that there was a significant difference in the amount of respiratory accessory muscle activation, inspiratory pressure, respiratory minute volume at the experimental group with stabilizer and control group with gymball exercise. Between-group difference was statistically significant only for rectus abdominis muscle activation. CONCLUSION: Both the stabilizer and the gymball exercises were effective in improving the respiratory rate but there was no difference between the two groups. Also, when comparing activity of muscle in both group, both groups were effective in improving and more effective than improvement of muscular activity of stabilizer in muscle of stabilizer.

Objective: This study investigated the effects of air stacking training (AST) on pulmonary function, respiratory strength, and peak cough flow (PCF) in persons with cervical spinal cord injury (CSCI). Design: Randomized controlled trial. Methods: A total of 24 persons with CSCI were randomly allocated to the AST group (n=12) or the incentive spirometry training (IST) group (n=12). Patients with CSCI received AST or IST for 15 minutes, with 3 sessions per week for 4 weeks, and all groups performed basic exercises for 15 minutes. In the AST group, after the subject inhaled the maximal amount of air as best as possible, the therapist insufflated additional air into the patient's lung using an oral nasal mask about 2-3 times. In the IST group, patients were allowed to hold for three seconds at the maximum inspiration and then to breathe. The pre and post-tests measured forced vital capacity (FVC), forced expiratory volume one at second (FEV1), maximal expiratory pressure (MEP), maximal inspiratory pressure (MIP) and PCF. Results: Both groups showed significant improvements in FVC, FEV1, MEP, MIP and PCF values after training (p<0.05). The FVC in the post-test and the mean change of FVC, FEV1, MIP were significantly higher in the AST group than the IST group (p<0.05). Conclusions: The findings of this study suggested that AST significantly improved pulmonary function, respiratory strength, and PCF in persons with CSCI. Therefore, AST should be included in respiratory rehabilitation programs to improve coughing ability, pulmonary function and respiratory muscle strength.

Smoking can be a significant cause of lung diseases and reduced respiratory functions. Among soldiers, smoking may have a negative impact on their health (physical strength) and well being. Information on differences in the respiratory functions of smokers and nonsmokers in the military services and the effects of the smoking duration and amount (i.e., the number of cigarettes smoked per day) would be useful. This study investigated smoking durations and smoking amounts among young male soldiers (N = 61). The forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), and forced expiratory volume in 1 sec/forced vital capacities (FEV1/FEC) were measured FVC, FEV1, or FEV1/FEC of smokers and nonsmokers were not significantly different, and FVC and FEV1 were inversely proportional to smoking duration. Besides, the number of cigarettes smoked per day was not correlated with respiratory functions. These findings may be attributed to the effect of the strenuous physical activity (e.g., military drills) undertaken by soldiers on their respiratory functions. Despite the lack of evidence for a difference in the respiratory functions of smokers and nonsmokers, this study recommends ongoing respiratory function management through smoking cessation programs and respiratory physiotherapy to manage the respiratory functions of Korean smoking soldiers.
