PURPOSE: The purpose of this study was to investigate whether a circuit aerobic exercise program positively affects pulmonary function and gait endurance in chronic stroke patients. METHODS: Twenty-four chronic stroke patients were allocated equally and randomly to an experimental group (n=12) or a control group (n=12). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally performed a circuit aerobic exercise for 30 minutes, while the control group additionally performed a general aerobic exercise, i.e., gait training on the treadmill for 30 minutes. These 30-minute exercise sessions were held three times per week for six weeks. Pulmonary function was assessed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV), and gait endurance was assessed using the 6-minute walk test (6MWT). RESULTS: In the both groups, FVC, FEV1, MVV, and 6MWT were significantly increased after training. Members of the experimental group showed significant improvements in FVC, FEV1, and MVV, and significantly greater improvements than controls (p<.05). However, 6MWT improvements were not significantly different in the two groups (p>.05). CONCLUSION: The devised circuit aerobic exercise program offers an effective rehabilitation aerobic exercise for improving pulmonary function and gait endurance in patients after chronic stroke.

PURPOSE: This study assessed the effect of exercise intervention methods on diaphragm movement, pulmonary function, and pulmonary strength in children with cerebral palsy (CP). METHODS: A total of 28 children with CP were randomly allocated to the general exercise group (n=9, GEG), respiratory exercise group (n=10, REG), and intensive exercise group (n=9, IEG). The exercise intervention was performed for 12 weeks. This study measured diaphragm movement, pulmonary function, and pulmonary strength under two different conditions before and after each exercise. Ultrasonography was used for measuring diaphragm movement, and Pony Fx was used to measure the forced expiratory volume in one second ($FEV_1$), peak expiratory flow (PEF), maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP). A Mann-Whitney test and ANOVA with a significance level of .05 were used for statistical analysis. RESULTS: Significant change was observed between the REG and the IEG as well as between the GEG and the IEG (p<.05). No significant difference was observed between the GEG and the REG. The diaphragm movement, $FEV_1$ PEF, MIP, and MEP were most improved in the IEG (p<.01). CONCLUSION: This study confirmed that intensive exercise is the most effective treatment method for improving diaphragm movement and respiratory function in CP children.

Purpose : The purpose of this study was to investigate the effect of abdominal muscle strengthening exercise on abdominal muscle strength and respiratory function in stroke patients. Methods : The subjects were 14 stroke patients (10 males, 4 females) hospitalized at W rehabilitation hospital in Busan City and randomly assigned to 7 exercise groups and 7 control groups. Exercise was performed in combination with an upper and lower extremity pattern of proprioceptive neuromuscular facilitation. Measurements of abdominal muscle strength and respiratory function were made before intervention and 4 weeks after intervention. Abdominal muscle strength was assessed using a digital manual dynamometer, and respiratory function was assessed by spirometry. The collected data were analyzed with a paired t-test and independent t-test and the significance level was set as α =.05. Results : The results showed that applying abdominal muscle strengthening exercise to stroke patients showed a significant increase in abdominal muscle strength and a significant difference between groups (p<.05). Maximal-effort expiratory spirogram (MES) readings were significantly increased in forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁), in the exercise group, and there were a significant differences between the groups in terms of FEV1 (p<.05). Slow vital capacity (SVC) was significantly increased in vital capacity (VC), tidal volume (TV), inspiratory reserve volume (IRV), and expiratory capacity (EC), and there were significant differences between the groups in VC, TV, expiratory reserve volume (ERV), EC, and inspiratory capacity (IC) (p<.05). Conclusion : Abdominal muscle strengthening exercise was effective in the abdominal muscle strength of stroke patients, and it was confirmed to have a positive effect on the enhancement of respiratory function. Therefore, it seems that exercise programs for stroke patients with respiratory weakness should include abdominal muscle strengthening exercises.

Purpose: This study was to evaluate the effect of cranio-cervical flexion based trunk stabilization exercise on gross motor function and posture alignment change in children with spastic cerebral palsy. Design: Randomized Controlled Trial. Methods: Twenty-six children participated in this study. All subjects were randomly assigned to either the Cranio-Cervical Flexion Based Trunk Stabilization Exercise (CCFTS) group (n=13) or the Trunk Stabilization Exercise (TS) group (n=13). In both groups were trained general physical therapy for 10 minutes, in the CCFTS group was trained cranio-cervical flexion based trunk stabilization exercise for 20 minutes and in the TS group was trained trunk stabilization exercise for 20 minutes. The training was provided 2 times a week during 8 weeks. All subjects were measured with the Gross Motor Function Measure (GMFM) and Cranio-Vertebral Angle (CVA) before and after intervention. Results: The results showed that the CCFTS have increased significantly in GMFM (B, C, D and E-dimension) and CVA, and the TS group have increased significantly in GMFM (B, C D and E-dimension). In particular, the CCFTS group improved significantly than TS group in GMFM (B, C and D-dimension) and CVA. Therefore, the cranio-cervical flexion based trunk stabilization exercise improved gross motor function and posture alignment in children with spastic cerebral palsy. Conclusion: These results suggest that cranio-cervical flexion based trunk stabilization exercise is feasible and suitable for individuals with a spastic cerebral palsy and can be used in addition to conventional physical therapy.

Purpose: The purpose of this study was to examine the effect of cycle ergometer exercise inducing movement of the affected side on knee joint function after total knee arthroplasty (TKA). Methods: The primary experiment was conducted on 19 members of the cycle ergometer exercise group to measure the muscle activity of the rectus femoris, hamstring, tibialis anterior, and gastrocnemius muscles during cycle ergometer exercise that induced the affected side's movement. In the second experiment, after receiving physiotherapeutic intervention for 30 min, the general bicycle exercise group and cycle ergometer exercise group performed the corresponding exercise for 15 min, 5 times per week, for 2 weeks. The ROM, muscle strength, pain, and balance were then measured and compared between the two groups. Results: In the results of the primary experiment, cycle ergometer exercise inducing movement of the affected side showed a significantly larger increase in the activity of leg muscles (rectusfemoris, hamstring, tibialis anterior, gastrocnemius) on the affected side than the general bicycle exercise (p <0.05). In the second experiment, the cycle ergometer exercise group showed a significantly larger increase in range of movement of affected side knee flexion and muscle strength of affected side knee flexion, knee extension, and plantarflexion than the general bicycle exercise (p <0.05). No significant between-group difference was observed in pain and balance before or after the intervention (p >0.05). Conclusion: Cycle ergometer exercise inducing movement of the affected side increases use of the muscles around the affected side knee joint after TKA more than general bicycle exercise and produces better effects for enhancing muscle strength. The application of cycle ergometer exercise inducing movement of the affected side is expected to reduce the patients' unbalanced use during the early postoperative period and help them to quickly return to normal daily life through rapid muscle strength recovery.

Exercise increases the expression and interaction of major neurotrophic factors such as brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF) at both central and peripheral tissues, which contributes to improved brain and neural plasticity and cognitive function. Previous findings have been to understand the effect of light or moderate intensity aerobic exercise on neurotrophic factors and cognitive function, not that of high intensity aerobic exercise. However, recent findings suggest that high intensity interval training is a safe, less time-consuming, efficient way to improve cardiorespiratory fitness and weight control, thus American College of Sport Medicine (ACSM)’s guidelines for exercise prescription for various adult populations also recommend the application of high intensity interval training to promote their overall health. High intensity interval training also enhances the expression of BDNF, IGF-1, and VEGF at the brain and peripheral tissues, which improves cognitive function. Increased frequency of intermittent hypoxia and increased usage of lactate as a supplementary metabolic resource at the brain and neural components are considered a putative physiological mechanism by which high intensity interval training improves neurotrophic factors and cognitive function. Therefore, future studies are required to understand how increased hypoxia and lactate usage leads to the improvement of neurotrophic factors and what the related biological mechanisms are. In addition, by comparing with the iso-caloric moderate continuous exercise, the superiority of high intensity interval training on the expression of neurotrophic factors and cognitive function should be demonstrated by associated future studies.

Purpose: The purpose of this study was to examine the effect of resistive exercise using an elastic band on range of motion, function and shoulder pain. Methods: Forty two subjects who had rotator cuff surgery were assigned either to a treatment or a comparison group, twenty one each. Following a six week period after surgery those in the treatment group participated in resistant exercise using an elastic band for four weeks. The subjects in the comparison group did not participate in the exercise program. The goniometer measured range of motion, a modified tool measured function, and a self report numerical rating scale measured pain. The data were analyzed using $x^2$ test, Fisher's exact, t-test and the Mann-Whitney Test. Results: Although not statistically significant, there was a trend that more subjects in the treatment group had increased range of motion. There was a statistically significance among the treatment group in terms of increased function (p=.015). Further the treatment group reported less pain that those in the comparison group (p<.001). Conclusion: The findings support that resistance exercise is an effective strategy for patients with rotator cuff repair.

Objective: The purpose of this study is to find out whether people still have problems with breathing after being quarantined for a certain period after being infected with COVID-19. Design: Two-group pretest-posttest design. Methods: A total of 36 subjects were included in this study. Subjects who have been quarantined after being infected with COVID-19 (the after-quarantine group, n=18) and those who have never had COVID-19 (the healthy group, n=18). Respiratory function was evaluated by subjects in resting state and after treadmill exercise. Subjects performed treadmill exercise at moderate intensity for 20 minutes. To compare the differences in respiratory function between groups, forced vital capacity (FVC), forced expiratory volume in first second (FEV1), and maximum voluntary ventilation (MVV) were evaluated using a spirometer. Results: The result of the study, there was a significant difference in FVC in the after-quarantine group between resting and after treadmill exercise (p<0.05). In the healthy group, there was no significant difference in respiratory functions between resting and after treadmill exercise. Conclusions: The meaning of this result is that people who have been quarantined with COVID-19 have lower respiratory function than healthy people who are not infected with COVID-19.

PURPOSE: This study analyzed the effectiveness of respiratory exercise in stroke patients conducted in Korea over the past 10 years (2012-2023). METHODS: Using the RISS, KCI, KISS, and NDSL databases, previous studies on stroke and respiratory exercise were searched, and relevant articles were collected following the PRISMA guidelines. Twelve articles were selected, and the quality of the studies was evaluated using the PEDro scale. RESULTS: Twelve studies were selected, and the qualitative evaluation of these studies showed that five articles received a score of six out of 10, while five articles received a score of five. The remaining two articles received scores of four and three, respectively. The intervention duration for respiratory exercise ranged from 20 to 30 minutes per session, with a frequency of three to five sessions per week, conducted over a period of three to eight weeks. These results indicated that respiratory exercise effectively improved the respiratory function, physical function, and respiratory muscle activation in stroke patients. CONCLUSION: Respiratory exercise was reported to have a positive affect the respiratory function, physical activity, and respiratory muscle activation in stroke patients.
