  • Purpose: Human body have biological rhythmic pattern in a day, which is affected by internal and external environmental factors. We investigated whether respiratory function was fluctuated according to the influence of time-of-day (around at 9 am, 1 pm, and 6 pm) in health subjects, using pulmonary function test (PFT). Methods: Eighteen healthy volunteers (8 men, mean ages; $22.4{\pm}1.6$, mean heights; $166.61{\pm}9.60$, mean weight; $59.3{\pm}10.3$) were recruited. Pulmonary function test (PFT) was measured at three time points in day, around 9 am, 1 pm, and 6 pm in calm research room with condition of under 55dB noise level, using a spirometer (Vmax 229, SensorMecis, USA). Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FVC/FEV1, and peak expiratory flow (PEF) were acquired. Results: In comparison of raw value of PFT among three time points, subjects showed generally better respiratory function at 9 am, than at other points, although no significance was found. In comparison of distribution of ranking for respiratory function in each individual, only PEF showed significant difference. In general, distributional ratio of subjects who showed best performance of respiratory function in a day was high. Conclusion: These findings showed that circadian rhythm by diurnal pattern was not detected on respiratory function throughout all day. But, best performance on respiratory function was observed mostly in the morning, although statistical significance did not exist.

  • Purpose: This study was conducted in order to investigate the effect on respiratory function, trunk control, and functional activities of daily living (ADL) through respiratory muscle strength training in patients with chronic stroke. Methods: Eighteen subjects who were six months post stroke participated in this study. The subjects were randomly allocated to two groups: experimental (n=10) and control (n=8). Both groups received physical therapy for five sessions, 30 minutes per week, during a period of six weeks. Subjects in the experimental group participated in an additional respiratory muscle strength training program, in which the threshold PEP device was used for 30 minutes per day, three days per week, during a period of six weeks. Results from pretest-posttest control were evaluated by pulmonary function forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), capacity of cough, trunk control, and functional ADL. Results: Significant improvement in the FEV1, PEF of pulmonary function (p<0.05), cough function (p<0.05), and trunk control (p<0.05) was observed among the groups. Conclusion: Respiratory muscle strength training improves pulmonary function, capacity of cough, and trunk control. These results suggest that respiratory muscle strength training is feasible and suitable for individuals with chronic stroke.

  • The purpose of this study compared the ability of feedback breathing training (FBT) and balloon blowing training to enhance the breathing of elderly people. The subjects were randomly and evenly divided into a feedback breathing training group (FBTG) and a balloon blowing training group (BBTG). Each group trained 3 times a week for 4 weeks, with the training suspended during the last 2 weeks. Pulmonary function measurements were obtained before the test and 2, 4 and 6 weeks after the test: forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF) and vital capacity (VC). A repeated-measures ANOVA was conducted for the significance test. The FBT resulted in a significant increase in the FVC, FEV1/FVC, PEF, and VC of the elderly smokers after 4 weeks and a significant decrease in the FVC, FEV1/FVC, and PEF after 6 weeks. The BBT resulted in a significant increase in the FVC, FEV1, FEV1/FVC, PEF, and VC of the elderly smokers after 4 weeks and a significant decrease in the FVC, FEV1/FVC, and PEF after 6 weeks. In conclusion, An at home breathing rehabilitation program, in addition to balloon blowing, could increase the breathing performance of elderly people.

  • Purpose: The purpose of this study was to identify the effects of the types of seat surface (static or dynamic seat surface) on the pulmonary functions during prolonged sitting. Methods: Thirty-four participants (20 males and 14 females) were recruited, and distributed randomly into dynamic prolonged sitting (DPS, n=17) and static prolonged sitting (SPS, n=17) groups. The DPS group was seated on a chair with a dynamic air cushion, and the SPS group was seated on a chair without a dynamic air cushion. The pulmonary function was assessed before sitting, and after participants had been seated for one hour. The pulmonary function [forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and Peak expiratory flow (PEF)] was measured using a spirometer. Results: Statistical analyses revealed significant differences in the time x group interactions of FVC, FEV1, PEF, and FEV1/FVC. The DPS group were significantly different in FVC, FEV1, PEF, and FEV1/FVC after prolonged sitting for one hour, compared to the SPS group (p<0.05). Conclusion: These findings suggest that dynamic sitting can prevent a decrease in the physiological function, such as pulmonary functions, rather than static sitting during prolonged sitting.

  • Purpose: We investigated to evaluate the effectiveness of water-based exercise (WE) program on respiratory functions for children with spastic diplegic cerebral palsy (CP). Methods: Fourteen children with spastic diplegic CP were randomly assigned, to either the experimental group (EG, n=7), or the control group (CG, n=7). Respiratory function was measured by a spirometer, a CardioTouch 3000S ( Bionet, Seoul, Korea) at a chair-sitting posture. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), peak expiratory flow (PEF) were measured. The intervention program will last 8 weeks, with three 40 minutes sessions per week (24 training session). The usual care and the addition of a WE program, were compared in the CG and EG, respectively. Results: The EG showed a significant increase in the FVC, FEV1, PEF after training (p<0.05), whereas there was no significant difference in the CP after training. In the EG, FVC increased significantly, compared to the control group (p<0.05), but not FEV and PEF. Conclusion: These findings suggest that WE program have an effect on the respiratory function in children with spastic diplegic CP.

  • Purpose: The purpose of the present study was to investigate the effects of a simultaneous dual-task and horse-riding simulator (HRS) training regime on pulmonary function and flexibility. Methods: Sixteen subjects were recruited and randomly allocated to two groups: a dual-task (DT) (n=8) or a single-task (ST) (n=8) training group. Flexibility and pulmonary function were assessed before and after HRS training. Both groups underwent HRS training for 4 weeks, 3 times/week in 15-minute training sessions. The ST group underwent HRS training and the DT group underwent dual-task HRS training, which consisted of throwing and catching a ball and ring catching while HRS training. Results: Training significantly increased flexibility and FVC (forced vital capacity) and FEV1 (forced expiratory volume in 1 second) in both groups (p<0.05), but FEV1/FVC and PEF (peak expiratory flow) were not significantly different after training in both groups (p>0.05). After the training, flexibility and FVC in the DT group were significantly greater than in the ST group (p<0.05), but FEV1, FEV1/FVC, and PEF were not significantly different (p>0.05). Conclusion: Simultaneous dual-task and HRS motor training improved flexibility, FVC, and FEV1, and our comparative analysis suggests that dual-task HRS training improved flexibility and FVC more than single-task training.

  • 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.
