Purpose: This study was to investigate the effects of respiratory rehabilitation training on the respiratory functions of hospitalized cervical spinal cord injury patients. Methods: One group pre and post test design was used. Subjects were 20 cervical spinal cord injury inpatients of the national rehabilitation center. Training program consisted of air cumulation training, manual assisted coughing training, and abdominal breathing. Trained rehabilitation nurse implemented 20 minutes program twice a day for 4 weeks. Respiratory function was measured as peak coughing flow rate, and perceived respiratory difficulty after activity on wheel chair for 30 minutes and during speaking and singing. Perceived respiratory difficulty was measured with modified Borg scale. Also content analysis was done with the result of open ended question about subjective feeling about training. All variables were measured 3 times before, 2weeks and 4 weeks after the program. Results: Peak coughing flow rate significantly improved after compared to before training. Also all three perceived respiratory difficulty variables decreased significantly after training. In the content analysis, 'it's easier to cough up phlegm' was the most frequent answered subjective feeling. 'Sound at speaking and coughing became louder', 'respiratory volume increased', and 'comfortable chest feeling' were frequent answered subjective feeling, in order. Conclusion: Although it is preliminary since no control group, respiratory rehabilitation training was found to be effective to improve respiratory function in terms of peak coughing flow rate, perceived respiratory difficulty, and subjective feeling. It is necessary further systemic research to investigate the effects of respiratory rehabilitation training.

Purpose : Stabilization exercise and respiratory muscle training are used to train trunk muscles that affect postural control and respiratory function. However, there have been no studies that combine stabilization exercise and respiratory muscle training. The purpose of this study is to investigate effects of stabilization exercise with and without respiratory muscle training on respiratory function and postural sway. Methods : Fifteen healthy adults were recruited for this experiment. All the subjects performed stabilization exercise with and without respiratory muscle training. For stabilization exercise with respiratory muscle training, the subjects sat on a gym ball wearing a stretch sensor. The subjects inspire maximally as long as possible during lifting one foot off the ground, alternately for 30 seconds. The stretch sensor was placed on both anterior superior iliac spine (ASIS), and the stretch sensor was used to monitor inspiration. For stabilization exercise without respiratory muscle training, the subjects sat on a gym ball and lifted one foot off the ground, without respiratory muscle training. Kinovea program used to investigate postural sway tracking during exercise. The maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) were measured using a spirometer to investigate changes of respiratory muscle strength before and after exercise. A paired t-test was used to determine significant differences postural sway tracking, MIP, and MEP between stabilization exercise with and without respiratory muscle training. Results : There were significantly lower a distance of postural sway tracking during stabilization exercise with respiratory muscle training, compared with stabilization exercise without respiratory muscle training (p<.05). The MIP and MEP were significantly increased after stabilization exercise with respiratory muscle training compared with before stabilization exercise with respiratory muscle trianing (p<.05). Conclusion : The results of this study suggest that stabilization exercise with repiratory muscle training would be recommended to improve postural control and respiratory muscle strength.

Whether respiratory muscle training is of benefit to the singing students is controversial. The purpose of the study is to investigate pulmonary function and the maximal inspiratory(MIP) and expiratory pressure(MET), and maximum phonation time in five female singing students before and after the specially programmed respiratory muscle training during 2 months. All singing students had average 4.8 years of formal classical voice training. Respiratory muscle training machine (Ultrabreath) was used to train respiratory muscle. Pulmonary function test data on simple pulmonary function, flow volume curve, static lung volumes are obtained from Vmax 6200. The MIP and MEP were measured using Spirovis, and the MPT were measured using hand-held stopwatch. Any pulmonary function test variables are not changed after respiratory muscle training. However, MIP and MEP were significantly increased between before and after respiratory muscle training. MPT increased significantly after training, compared to the pre-trained. MIP, MEP, and MPT after training in female singing students were 26%, 25% and 33% higher than those before training. The result indicated that the specially programmed respiratory muscle training is beneficial to improve respiratory muscle strength and vocal function without an increment in pulmonary function.

PURPOSE: The purpose of this study was to examine the effects of respiratory muscle training on respiratory function, respiratory muscle strength, and cough capacity in stroke patients. METHODS: This study used a nonequivalent control group pre-post test design. We recruited thirty-four stroke patients(16male, 18female), who were assigned to intervention (n=17), or control (n=17) groups. Both groups participated in a conventional stroke rehabilitation program, with the intervention groups also receiving respiratory muscle training 20 minutes a day, three times a week, for 4 weeks. Respiratory function (forced vital capacity) and respiratory muscle strength (maximal inspiratory pressure, maximal expiratory pressure) were assessed by spirometry. Cough capacity (peak expiratory flow) was assessed using a peak flow meter. The collected data were analyzed by independent and paired t-tests. RESULTS: The intervention group showed a significant increase in the forced vital capacity (FVC), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP) and peak expiratory flow (PEF) at the end of the program, while the control group showed no significant changes. CONCLUSION: This study showed that respiratory muscle training increased respiratory function, respiratory muscle strength, and cough capacity in stroke patients and prevented a decrease in cough capacity. These findings suggest that respiratory muscle training effect on respiratory function, respiratory muscle strength and cough capacity for rehabilitation in patients with stroke.

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.

This study reviews studies on the core stabilization of respiratory muscle training for the elderly health. Previous research data and presenting basic literature data suggest that respiratory activation is an important mechanism for core strengthening via exercise interventions for the elderly. The review found that first, the mechanism of improving the respiratory muscles weakened by aging to address the loss of core function due to old age sarcopenia among the elderly results entails promoting the autonomic nervous system by focusing on the respiratory muscle activation pattern, the core muscle sensation mobilized for body centering. Second, nerve roots, intraperitoneal pressure, and deep muscles in the trunk of the body can be promoted while controlling respiratory stimulation with cognitive feedback. Effortful inspiration increases the activation of respiratory assistive muscles and effortless exhalation can improve the core muscle mobilization by involving abdominal muscles. Third, through respiratory muscle training, the elderly can increase their awareness of spinal centering and improve the ability to control the deep core muscles that must be mobilized for core stabilization. In conclusion, respiratory muscle training to increase the utilization of the trunk muscles seems to be a useful core stabilization exercise for the elderly with chronic tension and joint degeneration.
