Purpose : This study investigated the effects of air stacking exercise on respiratory ability of patients with cervical cord injury. Methods : The subjects of this study were 30 patients with cervical cord injury were randomly placed in an experimental group(n=15) and a control group(n=15), respectively. Basic therapeutic exercise(ROM exercise, stretching exercise, strengthening exercise) were conducted twice a day for 30 minutes each time in all subjects and air stacking exercise was additionally conducted on the experimently group only. Air stacking exercise was conducted for 4 weeks, twice a day, 5 times a week and repeated 10 to 15 times each time. Lung capacity, MIC and, peak cough flow were measured and evaluated. Results : The results showed that FEV1, FVC, MIC, UPCF and APCF were significantly increased(p<.05), but FEV1/FVC didn't show the significant differences in an experimental group. In a control group, the findings showed that FEV1, FVC were increased significantly(p<.05) while FEV1/FVC, MIC, UPCF, and APCF didn't show the significant differences.There were significant differences in FEV1, FVC, MIC, and APCF between a experimental group and a control group in the results of Pulmonary Function Test after conducting the pulmonary rehabilitation. However, no significant differences were found in FEV1/FVC, and UPCF between a experimental and a control group(p>.05). Conclusion : air stacking exercise has positive effects on the improvements of cough functions and that of pulmonary functions such as lung volume, lung elasticity in patients with cervical cord injury.

PURPOSE: This study examined the correlation between the pulmonary function and respiratory muscle strengthening training on an unstable support surface and a stable support surface in stroke patients. METHODS: The study subjects were 22 stroke patients undergoing central nervous system developmental rehabilitation treatment. After excluding six dropouts, eight people in the experimental group and eight people in the control groups were classified by random sampling. Both groups performed central nervous system developmental rehabilitation therapy and were provided a 10-minute break. The experimental group was provided with an unstable support surface using Togu, and the control group was trained to strengthen the respiratory muscle in a stable support surface. Respiratory muscle strengthening training was conducted three times per week for 20 minutes. Before and after each group of experiments, a nonparametric test Wilcoxon signed rank test, and a Mann Whitney U-test analysis were used to analyze the variations between the two groups. All statistical significance levels (α) were set at 0.05. RESULTS: Both groups showed increases in the pulmonary function but showed significant differences only in the experimental group. There was a significant difference in the peak expiratory flow between the two groups. CONCLUSION: Central nervous system development rehabilitation treatment for patients with an impaired nervous system and respiratory muscle strengthening training on unstable support surfaces are effective in improving the pulmonary function of stroke patients. Therefore, they are expected to be applied to physical therapy programs to help various functional activities.

배경: 호흡재활치료는 만성 폐질환 환자들의 폐기능을 호전시키지는 못하나 운동허용능(exercise tolerance)을 호전시키는 것으로 알려져 있다. 그러나 이러한 운동허용능이 증가하는 것이 유산소운동 능력 (aerobic exercise capacity)이 중가하기 때문인지는 논란이 있으며, 아직 국내에서 는 호흡재활치료에 대한 보고가 없었다. 방법: 14명의 만성 폐질환 환자(만성폐쇄성폐질환 11명, 유육종증 1명, 기관지확장증 1명, 특발성 폐섬유화증 1명, 평균 연령 $57{\pm}4$세, 남자 12명, 여자 2명)를 대상으로 6 주간의 호흡재활치료를 시행하여 치료 전후의 폐기능과 운동허용능의 변화를 관찰하였다. 결과: 1) 대상 환자의 호흡재활치료 전 평균 노력성 폐활량(FVC), 1초간 노력성호기량($FEV_1$) 및 노력성 호기중간 기류량($FEF_{25-75%}$)은 각각 예측치의 $71.5{\pm}6.4%$, $40.6{\pm}3.4%$ 및 $19.3{\pm}3.8%$ 였으며, 총 폐용량(TLC), 기능적잔기용량(FRC) 및 잔기량(RV)은 각각 $130.3{\pm}9.3%$, $157.3{\pm}13.2%$ 및 $211.1{\pm}23.9%$이었고, 확산능(diffusing capacity) 및 최대 환기량(MVV)은 각각 $59.1{\pm}1.1%$ 및 $48.6{\pm}6.2%$이었다. 이들 각 폐기능의 지표들은 호흡재활치료 전후 유의한 변화는 없었다. 2) 자전거운동력측정계 (bicycle ergometer)를 이용한 운동부하 검사상 최대 운동량(maximum work rate)은 치료전 $57.7{\pm}4.9$ watts 에서 치료후 $64.8{\pm}6.0$ watts로(P=0.036), 최대산소섭취량($VO_2$ max)은 $0.81{\pm}0.07$ L/mm에서 $0.96{\mu}0.08$ L/mm로 (P=0.004), 무산소역치 (anaerobic threshold)는 $0.60{\pm}0.06$ L/mm 에서 $0.76{\mu}0.06$ L/min로(P=0.009) 호흡재활치료후 유의하게 증가하였다. 가스교환은 호흡재활치료 전후에 변화가 없었다. 3) 지구력시험 (endurance test)상 운동일(work)이 상지는 $4.5{\pm}0.7$ joule 에서 $14.8{\pm}2.4$ joule로 (P<0.001), 하지는 $25.4{\pm}5.7$ joule에서 $42.6{\pm}7.7$로 (P<0.001) 모두 재활치료 후 유의하게 증가하였다. 6분 보행거리는 $392{\pm}35$ 미터 에서 $459{\pm}33$ 미터로(P<0.001) 치료 후 연장되었고, 최대 흡기압도 $68.5{\pm}5.4$ $CmH_2O$에서 $80.4{\pm}6.4$ $CmH_2O$로 증가하였다(P<0.001). 결론: 만성 폐질환 환자에서 6주간의 호흡재활치료는 폐기능 및 가스교환을 호전시키지는 못하였지만 운동허용능(exercise tolerance)을 호전시키는 것으로 사료되었다.

The coronavirus disease 2019 (COVID-19) pandemic has been ongoing for more than 2 years. Many patients who recover from severe acute respiratory syndrome coronavirus 2 infection continue to have aftereffects such as dyspnea and fatigue, which may lead to functional decline. Therefore, the need for managing these symptoms using methods such as pulmonary rehabilitation (PR) has emerged. The purpose of this study was to report the effectiveness of PR in five patients with acute COVID-19. PR was performed in patients with persistent dyspnea and oxygen demand after COVID-19. All five patients were able to maintain an independent functional status before COVID-19. However, after acute COVID-19, they were unable to walk independently and needed assistance for activities of daily living due to dyspnea and fatigue. Therefore, they were referred to rehabilitation units, and PR was performed. The modified Medical Research Council dyspnea scale, maximal expiratory pressure (MEP), 6-minute walking test, forced vital capacity, and grip strength were assessed before and after PR, and the results were compared. After PR, the parameters improved, except for the MEP in one patient (patient 3) and the grip strength in another patient (patient 4). After PR, two out of five patients returned to work and the other three returned home. Therefore, we conclude that PR is necessary for patients with acute COVID-19 with activity limitations.

Background: There are limited number of studies that investigate clinical variables instead of chronic obstructive lung disease (COPD) management according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 classification. The aim of the study was to investigate whether there was a difference between GOLD 2017 classification and spirometric stage in clinical variables in patients with COPD. The data of 427 male patients with stable COPD were investigated retrospectively. Methods: Patients were allocated into combined assessment of GOLD 2017 and spirometric stage. Age, amount of smoking, pulmonary function, modified Medical Research Council (mMRC), incremental shuttle walk test (ISWT), Hospital Anxiety-Depression Scale (HADS), St. George's Respiratory Questionnaire (SGRQ), body mass index (BMI), and fat free mass index (FFMI) were recorded. Results: Seventy-three (17%) patients were in group A, 103 (24%) constituted group B, 38 (9%) were included in group C, and 213 (50%) comprised group D according to the combined assessment of GOLD 2017. Twenty-three patients (5%) were in stage 1, 95 (22%) were in stage 2, 149 (35%) were in stage 3, and 160 (38%) were in stage 4 according to spirometric stage. According to GOLD 2017, age, amount of smoking, mMRC, BMI, FFMI, SGRQ, HADS, forced vital capacity, forced expiratory volume in 1 second ($FEV_1$), and ISWT were significantly different between groups. Ages, amount of smoking, FFMI, BMI, HADS of group A were different from B and D. Smiliar values of $FEV_1$ were found in A-C and B-D. A and C had smiliar ISWT. According to spirometric stage, BMI, FFMI of stage 4 were statistically different. mMRC, ISWT, and SGRQ of stages 3 and 4 were different from other stages, amongst themselves. $FEV_1$ was correlated with mMRC, SGRQ, anxiety scores, BMI, FFMI, and ISWT. Conclusion: This study showed that the GOLD ABCD classification might not represent the severity of COPD sufficiently well in terms of lung function or exercise capacity. The combination of both spirometric stage and combined assessment of GOLD 2017 is important, especially for estimating clinical variables.

Objective: The objective of this study was to investigate the effects of Schroth's three-dimensional exercises in combination with respiratory muscle exercise (SERME) on Cobb's angle and functional movement screen (FMS). Design: Randomized controlled trial. Methods: Fifteen subjects with scoliosis were randomly assigned to two groups. Eight subjects were assigned to the experimental group and seven subjects were assigned to the control group. The experimental group underwent SERME using SpiroTiger (Idiag, Switzerland), while the control group performed only the Schroth's three-dimensional exercises (SE). Both groups performed exercises for one hour per day, three times a week for eight weeks. Cobb's angle, pulmonary function (forced vital capacity, forced expiratory volume at one second, and peak expiratory flow) and FMS were measured before and after the experiment. Results: After intervention, the SERME group showed a significant difference in Cobb's angle, FMS scores, and pulmonary function as compared to before intervention (p<0.05). In the SE group, there was a statistically significant difference in Cobb's angle, pulmonary function, and FMS scores compared to before intervention (p<0.05). The SERME group showed a significant difference in Cobb's angle and peak expiratory flow in pulmonary function compared to the SE group (p<0.05). Conclusions: The results suggest that SERME could be a more effective intervention for improvement of the Cobb's angle and pulmonary function for scoliosis patients.

Purpose: This study examined whether breathing exercises might increase the chest expansion and pulmonary function of stroke patients. Methods: Twenty four patients with stroke were assigned randomly into two groups: a combination of diaphragmatic resistive breathing and pursed-lip breathing exercise (CB) group (n=10) and control group (n=14). The CB group completed a 4-week program of diaphragmatic resistive breathing and pursed-lip breathing exercise. The subjects were assessed using the pre-test and post-test measurements of the chest expansion (length for resting, deep inspiration, deep expiration, deep expiration-inspiration) and pulmonary function (forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), vital capacity (VC), tidal volume (TV), expiratory reserve volume (ERV), inspiratory reserve volume (IRV)). Results: A comparison of the chest expansion between the pre and post tests revealed similar rest, deep inspiration, deep expiration, and deep expiration-inspiration lengths in the CB and control groups (p>0.05). A comparison of the pulmonary function between pre and post tests, revealed significant improvements in the FVC, FEV, PEF, VC, IRV, and ERV in the CB group (p<0.05). There was a significant difference in the FVC, FEV1, PEF, VC and IRV between the 2 groups (p<0.05). Conclusion: These findings suggest that breathing exercise should help improve the pulmonary function, such as the volume and capacity. This suggests that the pulmonary functions of stroke patients might be improved further by a continued respiratory exercise program.

Purpose: The purpose of this study was to examine the effects of the one-time aerobic exercise on pulmonary function, oxygen saturation, and smoking in male college students in their 20's. Methods: The experiment was performed on 11 healthy men who had no musculoskeletal or neurological diseases and who smoked. The subjects performed an aerobic exercise for 30 minutes, using a step box. Before and after the exercise, forced vital capacity (FVC), forced expiratory volume for one second (FEV1), and oxygen saturation were measured. Results: Between the two measurements, there were no significant differences in oxygen saturation (p>.05). However, the differences in FVC and FEV1 were statistically significant (p<.05). Conclusions: The results of this study demonstrate that a one-time aerobic exercise improves pulmonary function.

Purpose: The purpose of this study was to evaluate the effectiveness of pulmonary rehabilitation on lung function and fatigue in persons with chronic obstructive pulmonary disease (COPD). Methods: Thirty one persons with COPD participated in this study. Four groups were allocated as follows: experimental group 1 (under 10 years of the post-disease period), control group 1 (under 10 years of the post-disease period), experimental group 2 (over 10 years of the post-disease period), and control group 2 (over 10 years of the post-disease period). Results: Forced expired volume in one second (FEV1) % pred and lactic acid showed improvement in experimental group 1 and experimental group 2 after training. Control group 1 and control group 2 did not show improvement of FEV1% pred and lactic acid after training. However, FEV1% pred and lactic acid in experimental group 1 were not significantly different, compared with the experimental group. Conclusion: Results of our study suggest that implementation of a pulmonary rehabilitation program resulted in improvement of lung function and fatigue in persons with COPD not related to the post-disease period.
