PURPOSE: The respiratory function and range of joint mobility deteriorate due to aging, respectively, and the respiratory function may be related to the range of joint mobility. To the best of the authors' knowledge, there has been little research on how the deterioration of the range of joint mobility caused by aging is related directly to the respiratory function. This study investigated the relationship between the respiratory function and the range of joint motion in the cervical and lumbar regions of older adults. METHODS: Thirty-two older adults participated in the study. The forced vital capacity (peak expiratory flow: PEF and forced expiratory volume in 1 second: FEV1) and the range of cervical joint motion were assessed in all subjects. The results were analyzed using the Pearson's correlation coefficient. RESULTS: The respiratory function moderately correlated with age. A moderate correlation was observed between FEV1 and right cervical lateral flexion. PEF was moderately correlated with the lumbar lateral flexion. In addition, FEV1 correlated strongly with lumbar lateral flexion. CONCLUSION: The respiratory function was correlated with the cervical and lumbar lateral flexion. Therefore, rehabilitation of the respiratory function should involve improving the limited range of motion of the joints, and a stretching program is needed for older adults.
Purpose: Circumference of the chest and waist can be one of clinical indicator to reflect respiratory function in children with cerebral palsy. In this study, we compared to differences in the chest/waist circumference and maximal phonation time between children with spastic diplegia and hemiplegia. Methods: Seventeen children with spastic diplegic and hemiplegic cerebral palsy were recruited, who were matched to gender, age, height, weight, and body mass index for control of the known factors affected to respiratory function. The chest/waist circumference and were measured in each group, when children took a breath at rest and at maximal voluntary inspiration/expiration. Results: No significant differences were found in the chest and waist circumference and expansion between the two groups. However, only in the waist expansion, children with diplegic CP were significantly lower extensibility of lung, compared to the other group. In comparison of the maximal phonation time, a significant lower score was shown in children with spastic diplegic CP, compared to children with hemiplegic CP. Conclusion: Our results indicated that children with spastic diplegic CP had smaller chest wall and waist, compared to children with spastic hemiplegic CP. In addition, they showed a shorter time for sustaining phonation than spastic hemiplegic CP did. Therefore, spastic diplegic CP will be required for careful monitor regarding respiratory function in rehabilitation settings.
Objective: The purpose of this study was to changes in respiratory function due to differences in mask blocking grade, and effects on cardiovascular function during aerobic exercise. Design: Comparative study using paired t-test and analysis of variance measures. Methods: Male and female subjects were randomly divided into 4 groups according to mask blocking grade and measured respiratory functions before and after wearing the mask using spirometers, and their cardiovascular capabilities were measured using pulse oxygen meters and blood pressure meters before and after running for 10 minutes wearing mask. Used paired t-test, one-way ANOVA and Bonferroni post-test to compare the differences according to the mask blocking grade. Results: The experimental results verified that three groups except for the Non-mask group had a significant reduction in all values of FVC, FEV1, MVV, and PEF after wearing a mask compared to those before wearing a mask(p<0.05). Also a significant difference in cardiovascular functions was also observed after aerobic exercises wearing mask in all groups and there was a significant difference between all four groups(p<0.05). Conclusions: Lung patients with poor breathing, elderly and children with poor lung function, and professional groups who need to wear masks and take high-intensity work or aerobic movements are encouraged to take frequent breaks in advance, wear masks and social distancing at moderate and low levels.
The purpose of this study was to investigate the influence on sympathetic nerve system of interferential current therapy(ICT). The subjects were consisted of 20 senile patients, 10 males and 10 females with an average age of 71 years old. And systolic and diastolic blood pressure, temperature, heart rate, and respiratory were tested. The results were as follows: 1) Systolic and diastolic blood pressure were observed a statistical significance between before and during stimulation(p < .05). 2) Temperature was observed a statistical significance between before and during, and before and after 10 minutes stimulation(p < .05). 3) Heart rate and respiratory were not statistical significance(p > .05). These results are imply that electrical stimulation is directly or indirectly influence on sympathetic nerve system.

PURPOSE: The aim of this study was to investigate the effect of respiratory muscle strengthening training on pulmonary function and gait ability in patients with subacute stroke. METHODS: Eighteen inpatients with subacute stroke were recruited for this study. The subjects were randomized into two group. All study groups participated in a conventional stroke rehabilitation intervention 30minutes a day 5 times a week for 4 weeks. For subjects from the experimental group, respiratory muscle strengthening training was performed: 30minutes a day 3 times a week for 4 weeks. Outcomes such as the pulmonary function(Forced Vital Capacity, Forced Expiratory Volume in one second, Maximal Voluntary Ventilation) and gait ability(10m walk test, 6 minute walk test) were measured before and after training. RESULT: There were significant differences of pulmonary function(FVC, FEV1 and MVV) and gait ability(10m walk test, 6minute walk test) between pre and post in the experimental group. In comparison of two group, experimental group was significant different pulmonary function(FVC, FEV1, MVV) and gait ability(6minute walk test) than control group. but, There was no significant difference of the gait ability(10m walk test). CONCLUSION: This study showed experimental group can be used to improve pulmonary function and gait ability than control group. These findings suggest that the respiratory muscle strengthening training effect on pulmonary function and gait ability for rehabilitation in patients with subacute stroke.
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.

Purpose: Frequent desaturation due to immature incoordination of suck-swallow-breathing in preterm infants can influence multiple organs such as the heart, lungs, and brain, which can then affect growth and development. Most notably in preterm infants, feeding desaturation may even affect pulmonary function during gavage feeding. Because respiratory muscle activities may reflect the work required during respiration, we evaluated the differences in these activities between full-term and preterm infants with feeding desaturation, and investigated the correlations with clinical variables. Methods: Nineteen preterm infants with feeding desaturation (group 1) and 19 age-matched full-term infants (group 2) were evaluated. Oromotor function was evaluated using video recording. The root-mean-square (RMS) envelope of the electromyography signal was calculated to quantify the activities of muscles involved in respiration. The differences in RMS between both groups and the correlation with clinical variables including gestational age (GA), birth weight (BW), and Apgar scores (AS) at 1 and 5 minutes after birth were evaluated. Results: The RMS values of the diaphragm (RMS-D) and rectus abdominis (RMS-R) were significantly greater in group 1 compared to group 2, and the 1- and 5-min AS were significantly lower in group 1 compared to group 2. RMS-D and RMS-R were inversely correlated with GA, BW, 1- and 5-min AS in all infants. Conclusion: This study showed that respiratory muscle activities were augmented during feeding in preterm infants compared to full-term infants. Additionally, respiratory muscle activities were inversely correlated with all clinical variables.

PURPOSE: This study compared two different techniques of treadmill gait training, and evaluated the outcomes on gait and respiratory function in patients with hemiplegic stroke. METHODS: This was a single-blinded, randomized, controlled, comparative study, enrolling a total of 21 stroke patients in a rehabilitation hospital. Subjects were randomly assigned to either the treadmill walking training group with gradual speed increase (GSI group, n = 10), or treadmill walking training group with random speed changing (RSC group, n = 11). All participants performed 60 min of comprehensive rehabilitation therapy (5 × / week for 6 weeks). In additional, each group received either GSI or RSC treadmill walking training for 20 min (5 × / week for 6 weeks, total 30 sessions). Gait and respiratory function were measured before and after the 6-week training. RESULTS: Both groups showed significant improvements in the 10-m walking test, 6-minute walking test, timed up and go test, forced vital capacity (FVC), forced expiratory volume in 1 second, and maximal voluntary ventilation after training (p < .05). The GSI group showed a significantly greater increase in the FVC than the RSC group (+14.8 L vs. +12.5 L, p < .05). CONCLUSION: Both training methods can be effective for improving the walking and respiratory functions of stroke patients. However, our results indicate that treadmill walking training with gradual speed increase might be a more effective method for improving the respiratory function (FVC) than treadmill walking training with random speed changing.
Objective: The purpose of this study was to examine the effect of personalized complex aerobic training programs using wearable device on cardiovascular and respiratory functions in community based female elderly. Design: One group pre-post intervention study. Methods: Twenty-one older female participants lived in 'D' city were included. The personalized complex aerobic training program using wearable devices was applied to all participants for 4 weeks, 3 times a week, 30 minutes for per session. The participants' blood pressure, heart rate, oxygen saturation, respiration rate, submaximal exercise stress test, pulmonary function test and respiratory muscle strength test were evaluated before and after the complex training program. Results: After intervention, resting diastolic blood pressure, resting systolic blood pressure and the systolic blood pressure after submaximal exercise stress test were significantly decreased over time (p<0.05), and the submaximal exercise stress test duration were significantly increased over time (p<0.05). The maximal inspiratory pressure (MIP) was significantly increased compare to before the intervention (p<0.05). Conclusions: This study showed that personalized complex training program using wearable device can provide personalized exercise intensity according to cardiopulmonary function that give feedback, and these interventions have a significant effect on improving the cardiovascular and respiratory system functions of the female elderly in the community dwelling.

PURPOSE: Sitting with crossed legs may have an effect on maintaining a healthy body posture and proper functioning of the respiratory system. Thus, this study's objective was to identify whether or not sitting with crossed legs affects the vertebral angle, chest wall mobility, the pulmonary function, and the activity of the respiratory muscles. METHODS: Thirty healthy subjects were recruited for this study (16 males and 14 females). The vertebral angle, chest wall mobility, pulmonary function, and the activity of the respiratory muscle were measured while the subjects sat in the correct posture and these factors were again measured with the subjects seated with their legs crossed. Three-dimensional motion analysis was used to determine the trunk and lumbar vertebral angles. Surface electromyography was employed to measure the sternocleidomastoid, the rectus abdominis, and the external and internal oblique abdominis muscles. A tapeline was utilized to evaluate the subjects' chest wall mobility. Spirometry was assessed to determine the forced vital capacity and forced expiratory volume in one second. Paired t-tests were then performed (p<.05). RESULTS: There were significant differences in the trunk and lumbar flexion angles, the chest wall mobility, the activity of the right external oblique muscle, and the left internal oblique abdominis muscle. However, the difference in pulmonary function did not reach statistical significance. CONCLUSION: A crossed leg posture caused slight thoracic extension and lumbar flexion, which may lead to a decrease of the chest wall mobility and also to an imbalance of the abdominal muscles. Therefore, sitting with a crossed leg posture should be avoided. Yet a crossed leg posture did not have any clinical effect on the pulmonary function of healthy people. It may be necessary to study the effects of sitting with crossed legs over an extended period of time for patients suffering with impaired respiratory function.
