  • Objective: The purpose of this study was to investigate the effect of cervical range of motion training on the change in respiratory function growth rate at the group and individual level in stroke patients and stroke patients with tracheostomy tube. Design: A Multilevel Growth Model Methods: 8 general stroke patients and 6 stroke patients who had a tracheostomy tube inserted were subjected to cervical range of motion training 3 times a week for 4 weeks. Force vital capacity (FVC), Forced expiratory volume in the first second (FEV1), Forced expiration ratio (FEV1/FVC) and Manual assist peak cough flow (MPCF) were measured. Data were analyzed using descriptive statistics and multilevel analysis with HLM 8.0. Results: A significant difference was found in the respiratory function analysis growth rate of the entire group (p<0.05), and two groups were added to the research model. The linear growth rate of respiratory function in patients with general stroke increased with the exception of FEV1/FVC (p<0.05). Stroke patients with tracheostomy tube showed a decreasing pattern except for FVC. In particular, MPCF showed a significantly decreased result (p<0.05). Conclusions: This study found that the maintenance of improved respiratory function in stroke patients with tracheostomy tube decreased over time. However, cervical range of motion training is still a useful method for respiratory function in general stroke patients and stroke patients with tracheostomy tube.

  • Background: Incorrect postures of adolescents caused by the use of smart devices have been noted as a factor causing spinal diseases. Objectives: To examine the effect of joint mobilization and stretching on Cobb's angle and respiratory function in adolescent idiopathic scoliosis (AIS). Design: Cluster-randomized controlled trial. Methods: A total of 22 subjects with AIS were enrolled. They were allocated to two groups: the joint mobilization (n=11) and the stretching (n=11). All interventions were conducted for 30 minutes, three times a week for six weeks. Outcome measures were the Cobb's angle and respiratory function. The Cobb's angle and respiratory function measured using the X-ray and Micro-Quark. Results: Joint mobilization group showed significant differences in Cobb's angle and respiratory function, but stretching group showed significant differences Cobb's angle. The differences in peak expiratory flow (PEF) between the two groups were significant. Conclusion: This study proved that joint mobilization is a more effective intervention for AIS to improve Cobb's angle and respiratory function, when compared to stretching.

  • Purpose : This study examines the effect of trunk stabilization program on the body balance, lung capacity, and muscular activity of the rectus abdominis and external oblique of healthy adults. Method : A survey was conducted for 20 students of K University located in the city of Y in Gyeongsangbuk-do Province of Korea. The trunk stabilization program consisted of a hollowing exercise, curl-up, bridging exercise, and birddog exercise. This was performed 14 times in total (7 times a week for two weeks). For analysis, good balance was used to measure both static and dynamic balancing ability. A peak flow meter was used to measure the maximum expiratory flow, and MP150 was used to measure muscular activity of the rectus abdominis and external oblique. Result : After the trunk stabilization program, the participants showed a difference in score and time taken to achieve static and dynamic balance, and muscular activity of the rectus abdominis and external oblique at a statistically significant level (p<0.05). However, no significant difference was observed in the left-to-right distance and front-to-back distance in a dynamic balance, and the lung capacity (p>0.05). Conclusion : The results showed that the trunk stabilization program was effective in enhancing both static and dynamic balancing ability and muscular activity. It also increased the lung capacity although the change was not at a statistically significant level.

  • Peak expiratory flow rate(PEF) is a very important diagnostic parameter obtained from the forced vital capacity(FVC) test. The expiratory flow rate increases during the short initial time period and may cause measurement error in PEF particularly due to non-ideal dynamic characteristic of the transducer. The present study evaluated the initial rise slope($S_r$) on the flow rate signal to compensate the transducer output data. The 26 standard signals recommended by the American Thoracic Society(ATS) were generated and flown through the velocity-type respiratory air flow transducer with simultaneously acquiring the transducer output signal. Most PEF and the corresponding output($N_{PEF}$) were well fitted into a quadratic equation with a high enough correlation coefficient of 0.9997. But only two(ATS#2 and 26) signals resulted significant deviation of $N_{PEF}$ with relative errors>10%. The relationship between the relative error in $N_{PEF}$ and $S_r$ was found to be linear, based on which $N_{PEF}$ data were compensated. As a result, the 99% confidence interval of PEF error was turned out to be approximately 2.5%, which was less than a quarter of the upper limit of 10% recommended by ATS. Therefore, the present compensation technique was proved to be very accurate, complying the international standards of ATS, which would be useful to calibrate respiratory air flow transducers.

  • Purpose : The purpose of this study is to compare the effects on abdominal muscle thickness and breathing by applying trunk strength exercise and deep stabilization exercise along with breathing exercise, which is the main respiratory muscle during breathing, to present an efficient exercise method with diaphragm breathing. Methods : This study was performed on normal 6 females and 14 males subjects. They were divided into 2 groups which trunk strength exercise and deep stabilization exercise group. The trunk strength exercise group (TSE) attended prone press-up, crunch and pelvic tiling. The deep stabilization exercise group (DSE) attended abdominal drawing, horizontal side-support and bridging exercise. Breathing exercise was performed for each set break time for 1 minute. Results : First, in the comparison of the change in the thickness of the abdominal muscle between the trunk strength training group and the deep stabilization group before and after exercise, there was a statistically significant difference in the comparison of transverse abdominis (TrA), rectus femoris (RF), external oblique (EO), internal oblique (IO) (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Second, in the comparison of changes in respiratory function between the trunk strength exercise group and the deep stabilization exercise group before and after exercise, there were statistically significant differences in the exerted forced vital capacity (FVC), forced expiratory volume at one second (FEV1), peak expiratory flow (PEF) in the comparison before and after the experiment (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Conclusion : As a result of this study, it can be said that both trunk strength exercises and deep stabilization exercises along with diaphragm breathing are exercises that strengthen deep and superficial muscles, and have a positive effect on breathing function as well as muscle strength. However, it is not known which exercise was more effective, and because it was combined with breathing exercise, the interference effect appeared.

  • This study was designed to examine the aerobic capacity and ventilatory response during an incremental exercise in elite high school cyclists. Twelve boys ($17{\pm}1\;yr$, $175{\pm}5\;cm$, $70{\pm}9\;kg$) participated in anthropometric measurements, incremental exercise testing, and pulmonary function tests. During incremental exercise testing using a cycle ergometer, their maximal oxygen uptake ($VO_2max$), maximal power output, ventilation, ventilatory equivalents for oxygen ($V_E/VO_2$) and carbon dioxide ($V_E/VCO_2$), respiratory rate, and tidal volume were measured. Time variables such as inspiratory time (Ti), expiratory time (Te), breathing time (Tb), and inspiratory duty cycle (Ti/Tb), as well as inspiratory flow rate ($V_T$/Ti) were assessed. Pulmonary function of vital capacity (FVC), forced expiratory volume in one second ($FEV_1$), $FEV_1$/FVC, and peak expiratory flow were evaluated. Their $VO_2max$, maximal heart rate, and Wmax were $57.5{\pm}3.9\;ml{\cdot}kg^{-1}{\cdot}min^{-1}$, $194.1{\pm}8.6\;beat{\cdot}min^{-1}$, and 452 W, respectively. $VO_2max$ was not related to any anthropometric parameters. Most ventilatory variables progressively increased with exercise intensity. As intensity increased, Ti, Tb, Tb decreased while Ti/Tb was maintained. Below an intensity of 250 W, height, weight, body mass index, and body surface were highly correlated with $V_T$/Ti and Ti/Tb (p<0.05). Collectively, $VO_2max$ appeared to be lower than adult cyclists, suggesting a different pattern of ventilatory control as age advances. Morphological characteristics were not related to $VO_2max$ in the population. Time variables of ventilatory response seemed to be related only at an exercise intensity level of less than 250 W. $V_T$/Ti may be related to exercise endurance capacity, but Ti/Tb was similar to adult cyclists.

  • 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.

  • Background: This study was aimed to determine the effects of deep abdominal muscle exercises (DAME) and thoracic mobility exercises (TME) on pulmonary function. Methods: This study was conducted with 22 college students who are in their 20s and have no problem carrying out activities of daily living. All subjects were randomly assigned to either the DAME group (11) or the TME group (11) to undertake the exercises for 2 weeks. To measure pulmonary function of subjects, forced vital capacity (FVC), forced exploratory volume in 1 second (FEV1) and peak expiratory flow (PEF) were measured using chest graph. Chest expansion of subjects was also measured with tape ruler. These measurements were performed on the first day before the exercise program started and on the next day after the 2-week exercise program was completed. A paired-t test was performed to compare the differences in pulmonary function before and after the exercise program, and an independent t-test was performed to compare the two groups. Results: The results of this study were as follows: 1) In comparison of pre- and post-exercise changes in the DAME and TME groups, both groups showed significant increase in chest expansion and PEF after the exercise program, compared with the baseline data (p<.05). Both groups also demonstrated improvements in FVC and FEV1 after the exercise program, compared with the baseline data. However, the differences were not statistically significant (p>.05). 2) The comparison of the DAME and TME groups revealed no significant differences in chest expansion, FVC, FEV1 and PEF (p>.05). Conclusion: It is therefore concluded that both DAME and TME were effective in improving pulmonary function.

  • Objectives This systematic review aimed to provide evidence of the effectiveness and safety of manual therapy for asthma in children and adolescents. Methods We queried eight electronic databases (PubMed, Ovid-MEDLINE, EMBASE, The Cochrane Library, CNKI, ScienceON, KISS, and RISS) up to the end of April 2022. We included only randomized controlled trials (RCTs) investigating manual therapy for the treatment of asthma in children and adolescents. The methodological quality of the included RCTs was evaluated using the Cochrane risk-of-bias tool 1.0. Results Four RCTs were eligible for inclusion. Meta-analysis could not be performed due to the heterogeneity of the studies. One study showed the statistical significance of SMD 0.41 (95% CI: 0.06, 0.76, p<0.05) in the comparison with the osteopathic therapy group and the sham control group before and after treatment on the same day of peak expiratory flow. Conclusions This possibility was observed in a non-pharmacological approach to manual therapy. Manual therapy can be considered as an adjunct therapy for asthma treatment in children and adolescents who have difficulty with drug therapy.
