  • Background: Posterior-anterior (PA) vertebral mobilization, a manual therapy technique has been used for relieving pain or stiffness treating in spinal segment for in clinical practice, however evidence to gauge efficacy is yet to be synthesised. Objects: This study aimed to investigate the effect of PA mobilization of the thoracic spine on the respiratory function in patients with low back pain (LBP). Methods: The study participants included 30 patients with chronic LBP. They were randomly allocated to the experimental and control groups. The experimental and control groups received PA mobilization of the T1-T8 level of the thoracic spine and placebo mobilization, respectively. All patients received interventions for 35 minutes a day, five times a week, over 2-week period, respectively. Forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), peak expiratory flow (PEF), forced expiratory flow 25~75% ($FEF_{25{\sim}75%}$), and chest wall expansion were measured before and after the intervention. Statistical analysis was performed using independent t-test and two-way analysis of variance, and Pearson's correlation analysis was used to compare the correlation between respiratory function and chest measurement. Results: The experimental group showed significant improvements in FVC, $FEV_1$, PEF, $FEF_{25{\sim}75%}$ (p<.05), and chest wall expansion (p<.05) compared with the control group. Conclusion: PA mobilization of the upper thoracic spine may be beneficial for improving respiratory function parameters including FVC, $FEV_1$, PEF, $FEF_{25{\sim}75%}$, and chest wall expansion in patients with chronic LBP.

  • The objective of the study which utilised population based data was to determine the respiratory condition of elementary school children in Gangneung. From October 9th to December 14th, 2006, Pulmonary Function Tests (PFT) including Forced Vital Capacity (FVC) and Forced Expiratoy Volume in I Second $(FEV_1)$ were conducted on the target group of children using a spirometer. The prevalence of asthmatic symptoms was 29.8% among boys and 39.6% among girls. By using logistic regression, we found that family history of allergic rhinitis (OR=3.90, CI=1.05-14.51), experience of allergic conjunctivitis (OR=4.67, CI=1.54-14.16) and atopic dermatitis (OR=2.86, CI=1.17-7.05) significantly increased the asthmatic symptoms. Also, a family history of asthma and food allergy were associated with asthmatic symptoms. In relation to housing and environmental risk factors, residences under the ground (OR=3.59, CI=1.35-9.51) and big-size dolls (OR=2.71, CI=0.86-8.53) significantly increased the prevalence of asthmatic symptoms. For PFT, above four families, exposure of passive smoking and pets significantly reduced FVC in both groups (p<0.05). In girls, a big-size doll was significantly associated with decreased lung function (FVC and $FEV_1$). In boys, using bed significantly reduced $FEV_1$. Also, the risk of asthmatic symptoms was found to increase when the house has been built for 5 years or more, the house is close to a road $({\leq}100m)$, a gas/Kerosene heater or carpet is utilized within the house. However, their differences were not significant. It is concluded that genetic factor such as a family history of respiratory disease, allergic symptoms and housing risk factor are related to asthmatic symptoms. These results were worth noting because the findings will help address risk factors related respiratory symptoms especially in relation to housing and environment.

  • 연구배경 : 기관지 천식은 가역적인 기도 폐쇄를 특징으로 하지만 치료에 대한 호전 정도에 차이를 보이며 기도의 비가 역적 구조 변화와 관련되는 것으로 보인다. 저자들은 폐 환기능과 고해상 CT를 이용하여 치료 후 기도폐쇄의 호전 차이가 기도의 구조적 변화와 관련되는가를 알아보고자 하였다. 방 법 : 단순 흉부 방사선 촬영에서 정상 소견을 보이는 천식환자 40명을 대상으로 치료 시작 3일내 폐 기능 검사와 고해상 CT를 시행하였다. 매일 PEFR을 측정하였고 그 변화에 따라 대상 환자들을 분류하였다. 초기 PEFR이 정상 범위이면 경증군 (=Group0), PEFR의 30% 증가가 3일이내면 조기반응군(=Group1), 2주이내면 후기반응군(=Group2)으로 분류하였고 다시 PEFR의 정상 범위 도달시기가 3일이내면 조기정상반응군(=Group3), 2주이내면 후기정상반응군(=Group4), 2주내에 도달하지 못한 경우 미정상반응군(=Group5)으로 분류하였다. 결 과 : 연령은 경증군에서 다른 군들에 비해 유의하게 낮았으나 다른 군들간에는 유의한 차이가 없었다. 이환기간은 후기반응군에서 경증군, 조기반응군 보다 유의하게 길었다. FVC(%), $FEV_1$(%)는 치료에 대한 반응이 느릴수록 유의하게 낮았다. $FEV_1$/FVC(%)는 조기반응군과 후기반응군에서 경증군에 비해 유의하게 낮았으며 미정상반응군에서 경증군, 조기 및 후기정상반응군보다 유의하게 낮았다. 공기포획은 호전이 느릴수록 유의하게 많았다. 점액저류는 경증군에서 조기 및 후기반응군에 비해 많았으며, 경증군, 후기정상반응군, 미정상 반응군에서 조기정상반응군보다 많았다. 결 론 : 비교적 단기간내에 기도 폐쇄에서 호전되는데 차이를 보이는 것은 만성적인 염증 반응의 지속시간이 중요하며, 초기 기도폐쇄의 정도가 관련이 있어서, 본 연구에서는 고해상 CT를 통한 구조적 변화의 차이를 뚜렷이 볼 수는 없었지만, 집중적인 치료를 통해 만성 염증 반응을 소실시카고 기도폐쇄가 없는 무증상 상태로 이르도록 하는 것이 환자의 예후에 중요할 것으로 본다.

  • 연구배경 : 폐기능 검사는 폐질환을 진단하는 가장 기본적인 검사방법이며, 현재 연령과 신장을 포함하는 폐기능 검사의 예측식이 많이 이용되고 있다. 체성분 중 체지방량의 감소는 폐용적 증가와 상관관계가 있으며, 제지방량은 대개 근육으로 구성되어 있어 호흡근 훈련을 포함하여 물리적인 노력에 의해 증가될 수 있다. 이런 관점에서 볼 때 체지방량과 근육량의 변화는 폐기능에 영향을 미칠 가능성이 많다. 본 연구는 연령과 신장 뿐만 아니라 체질량지수, 체지방률, 제지방지수가 노력성 폐활량, 1초간 노력성 호기량, 노력성 호기중간유량 등 노력성 호기곡선에 미치는 영향을 알아보고자 하였다. 방 법 : 2000년 1월부터 2001년 12월까지 영남대학교 의과대학 부속병원 건강검진센터를 방문한 사람 중 폐기능 검사와 체성분 분석을 시행하여 폐기능이 정상이고 과거 특이한 병력이 없으며 검진 결과가 정상인 300명(남자 : 150명, 여자 : 150명) 평균 연령은 $45{\pm}13$세였다. 폐활량 측정법을 이용하여 측정한 폐기능 검사결과와 체성분 분석결과를 이용하여, 이들간의 관계를 다중회귀분석을 이용하여 분석하였다. 결 과 : 남자의 경우 노력성 폐활량을 설명하는데 제지방지수가 통계적으로 유의하였으며(p<0.05, $r^2=0.432$), 1초간 노력성 호기량을 설명하는데 체지방률과 제지방지수가 통계적으로 유의하였다(p<0.05, $r^2=0.567$). 여자의 경우 노력성 폐활량과 1초간 노력성 호기량을 설명하는데 체질량지수(FVC: p<0.05, $r^2=0.435$, $FEV_1$: p<0.05, $r^2=0.597$)와 체지방률(FVC: p<0.05, $r^2=0.491$, $FEV_1$: p<0.05, $r^2=0.654$)이 통계적으로 유의하였으며, 노력성 호기중간유량은 체지방률과 유의한 관련이 있었다(p<0.05, $r^2=0.337$). 결 론 : 체질량지수 및 체지방률 그리고 제지방지수는 노력성 폐활량, 1초간 노력성 호기량에 영향을 미치는 독립변수로 생각되며, 이들 체성분을 고려한 폐기능 검사도 임상에서 활용할 수 있을 것으로 생각된다.

  • The purpose of this study was to find out an inspiratory muscles training program's therapeutic effects on stroke patients' respiratory function. For the purpose, this study targeted 20 stroke patients being hospitalized in K hospital in Daegu, and diveded the patients into the both groups of Inspiratory muscle training(IMT) group and control group, randomization. The 10 patients in the IMT group was applied the inspiratory muscles training. The control group was composed of other 10 patients. IMT group was given a inspiratory muscle training program for 30 minutes per times, 5 times a week for 6 weeks. The investigator measured the patients' respiratory function compared changes in the function and ability before and after the IMT. The results of this study are as follows. Investigating the inspiratory muscle training group's lung functions, there appeared some significant differences in the tests the FVC(Forced vital capacity), FEV1(Forced expired volume in one second) before and after the training(p<.05), but the control group had no significant in the same tests before and after(p<.05). The differences in the both groups after depending the inspiratory muscles training were significantly found in the tests of FVC, FEV1, FEV1/FVC(p<.05). The maximum inspiratory pressure showed some significant differences in the inspiratory muscle training group(p<.05), but didn't show any significant difference in the control group(p>.05). Conclusionally, it will be judged that the inspiratory muscles training program will improve stroke patients' respiratory function, and it is considered that will move up stroke patients' gait and body function.

  • Background: This study aims to examine the useful- ness of the portable spirometer "The Spirokit" as a clinical diagnostic device through technology introduction, precision test, and correction. Design: Technical note Methods: "The Spirokit" was developed using a propeller-type flow rate and flow rate measurement method using infrared and light detection sensors. The level of agreement between the Pulmonary Waveform Generator and the measured values was checked to determine the precision of "The Spirokit", and the correction equation was included using the Pulmonary Waveform Generator software to correct the error range. The analysis was requested using the ATS 24/26 waveform recognized by the Ministry of Food and Drug Safety and the American Thoracic Society for the values of Forced Voluntary Capacity (FVC), Forced Expiratory Volume in 1second (FEV1), and Peak Expiratory Flow (PEF), which are used as major indicators for pulmonary function tests. All tests were repeated five times to derive an average value, and FVC and FEV1 presented accuracy and PEF presented accuracy as the result values. Results: FVC and FEV1 of 'The Spirokit' developed in this study showed accuracy within ± 3% of the error level in the ATS 24 waveform. The PEF value of 'The Spirokit' showed accuracy within the error level ± 12% of the ATS 26 waveform. Conclusion: Through the results of this study, the precision of 'The Spirokit' as a clinical diagnosis device was identified, and it was confirmed that it can be used as a portable pulmonary function test that can replace a spirometer.

  • Purpose: Idiopathic scoliosis is a structural lateral curvature of the spine of unknown etiology. The relationship between degree of spine curvature and cardiopulmonary function has not yet been investigated. The purpose of this study was to determine the association between scoliosis and cardiopulmonary characteristics. Methods: Ninety children who underwent preoperative pulmonary or cardiac evaluation at a single spine institution over 41 months were included. They were divided into the thoracic-dominant scoliosis (group A, n=78) and lumbar-dominant scoliosis (group B, n=12) groups. Scoliosis severity was evaluated using the Cobb method. In each group, relationships between Cobb angles and cardiopulmonary markers such as forced vital capacity (FVC), forced expiratory volume in one second ($FEV_1$), $FEV_1$/FVC, left ventricular ejection fraction, pulmonary artery flow velocity, and tissue Doppler velocities (E/E', E'/A') were analyzed by correlation analysis linear regression. Results: In group A, 72 patients (92.3%) underwent pulmonary function tests (PFTs), and 41 (52.6%) underwent echocardiography. In group B, 9 patients (75.0%) underwent PFT and 8 (66.7%) underwent echocardiography. Cobb angles showed a significant negative correlation with FVC and $FEV_1$ in group A (both P<0.05), but no such correlation in group B, and a significant negative correlation with mitral E/A ratio (P<0.05) and tissue Doppler E'/A' (P<0.05) in group A, with a positive correlation with mitral E/A ratio (P<0.05) in group B. Conclusion: Pulmonary and cardiac function was significantly correlated with the degree of scoliosis in patients with thoracic-dominant scoliosis. Myocardial diastolic function might be impaired in patients with the most severe scoliosis.

  • 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.
