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.

A 68-year-old man with Guillain-Barre syndrome after the resection of right upper lobe for squamous cell lung cancer is presented. He developed a sudden, symmetric, extremity weakness, respiratory insufficiency, and sensory ataxia on postoperative day 6. He was intubated emergently and placed on a ventilator. Electrodiagnostic studies were performed on days 2, 20, and 40 following the onset of weakness. Motor nerve conduction abnormalities were the predominant findings. Prolonged motor distal latencies, temporal dispersion, and partial motor conduction blocks were present and formed the diagnostic features of Guillain-Barre syndrome. With supportive care and additive use of intravenous immunoglobulin, the illness resolved 6 weeks later after the onset of weakness.

1. 도입 및 배경 Lou Gehrig 병이라고 알려져 있는 근위축성 측삭경화증은 중추신경계 중 운동신경의 퇴행성 변화에 의한 진행성 질환이다. 이 병은 근육의 마비와 약화, 강직의 진행과 더불어 언어장애, 연화장애, 호흡장애가 동반된다. ALS는 환자나 가족들에게 엄청난 고통을 주는 질환으로 이병은 발병 후 3-5년 내에 약 $75\%$가 사망한다. 그리고 연하장애가 주된 증상이거나 고령에서 발병하였을 때에는 생존기간이 더욱 단축되는 경향을 나타낸다. 그리고 치명적인 호흡장애로 인해 대부분 사망하게 된다. 현재 의학계에서는 이 병의 원인도 알고 있지 못하고, 증상에 대한 아무런 치료방법도 제시하지 못하고 있는 실정이다. 2. 역학 원발성 운동신경원성 질환의 발생률은 100,000당 약 7명이고, ALS는 이 중 약 $65-85\%$를 차지한다. 전 세계적으로 1년에 약 2-4명/100,000이 발생하고 있으며 시간이 경과할수록 점차 증가하고 있는 추세이다. 3. 연구방법 EMG나 Biopsy 등을 통해 신경과 전문의가 ALS로 진단한 환자 중 상지대학교 부속한방병원에서 3개월 이상 입원치료를 받은 환자 18명을 대상으로 임상연구를 진행하였고, 설문조사는 외래에 내원한 환자 중 설문에 응답한 환자 28명을 포함한 총 46명의 환자들을 대상으로 시행하였다. 치료방법은 침, 약침, 봉약침, 한약 등을 환자의 체질을 고려하여 변증에 따라 적용하였고, 환자의 상태 변화는 ALSFRS(ALS Functional Rate Scale)를 사용하여 관찰하였다. 4. 결과 본 연구결과 ALS의 치료에 한의학적 치료방법은 유효한 것으로 나타났다. 특히 본 질환이 시간이 경과하면서 $100\%$ 악화되는 질환임을 감안한다면 한의학적 치료를 통해 약 $40\%$의 환자에서 몸의 상태나 언어장애, 만성적 피로 등이 호전되었고, 근력도 증가되는 결과를 나타내었다.

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.

불포화지방산이 풍부한 오리고기는 예로부터 보양식으로 많은 사랑을 받았다. 오리고기가 기력을 회복하는 음식으로 널리 알려진 이유는 필수 아미노산과 레시틴이라는 성분이 풍부하기 때문이다. 아미노산은 근력 향상에 도움을 주고 신체 능력을 강화하며 피로 해소에도 탁월한 역할을 한다고 알려지며, 레시틴이 부족할 경우 피로를 느끼고 면역력이 저하되기 때문에 꾸준하게 섭취를 해주는 것이 중요하다. 오리에 풍부한 비타민A는 체내 병균 저항력을 높여준다. 또한 면역 세포의 기능을 촉진해 감염 질환이 걸리지 않게 몸을 보호하는 역할을 한다. 특히 비타민A가 부족하면 호흡기계 질환이 걸리기 쉬우므로 호흡기 건강에 신경을 쓴다면 평소 비타민A가 풍부한 음식을 먹는 게 좋다. 또한 오리고기에 풍부한 리놀레산은 성장기에 꼭 필요한 필수 지방산으로 인체 기능에 꼭 필요한 요소다. 다른 육류에 비해 열량이 낮고 단백질이 풍부해 다이어트를 할 때도 부담없이 즐길 수 있는 오리고기 신제품을 소개한다.

The aim of this study was to investigate the effect of combine exercise on the fall injury related index and myokine in elderly women. Sarcopenia leads to a loss of strength, alter on to a decreased functional status, impaired mobility, a higher risk of falls, and eventually an increased risk of mortality. Aerobic exercise characterized by rhythmic and repetitive movements of large muscles, for sustained periods that depends primarily on the use of oxygen to meet energy demands through aerobic metabolism, and that is structured and intended to generate improvements in cardiopulmonary fitness, body composition, and cardiorespiratory health. Resistance training has performance in the elderly. As combined exercise therapy can be used to enhance muscle functions and cardiopulmonary functions, it is being highlighted as an effective health management methods for the aged. The myokine has been regarded an important factor of exercise how muscle communicate adipose tissue, bone and muscle to exert beneficial effects at the whole body level.

The effects of inspiratory muscle training in conjunction with aerobic exercise on inspiratory muscle strength, pulmonary function, and maximal oxygen uptake(VO₂max) were examined. Twenty four healthy collegiate men were divided into three groups; respiratory muscle training group(RTG; n=8), running exercise group(REG; n=8), and both respiratory muscle training and running group(BTG; n=8). Their pulmonary function, maximal inspiratory pressures(PImax), and VO₂max were assessed before and after intervention. RTG underwent inspiratory muscle training(IMT) with load set to 50 % of PImax, 30 times per session, twice a day, 4 days a week REG ran on a treadmill at 70-75 % of VO₂max for 30 min a day, 4 days a week. BTG participated both IMT and the running exercise. Participant's anthropometric parameters and pulmonary function were not changed. VO₂max increased by 6.1±3.3 %, 5.9±6.6 %, and 10.0±8.3 % in RTG, REG, and BTG, respectively(p< .05), and PImax also increased by 21.7±14.3 %, 19.7±12.0 %, and 27.0±12.1 % in RTG, REG, and BTG, respectively, but no group differences were found. Based on the study, although statistically insignificant, BTG showed the biggest increase of VO₂max and PImax indicating a possible synergic effect of inspiratory muscle training and aerobic exercise on respiratory responses.

Introduction: REM sleep which shows characteristic muscle atonia and increased resistance of upper respiratory track is known to be vulnerable to sleep apnea. Previous studies reported that REM sleep-dependent (or related) obstructive sleep apnea syndrome (REM-dependent OSA) could be one of sleep disordered breathing. The present study aimed to investigate clinical findings and polysomnographic variables of REM-dependent OSA. Methods: Fifty-six patients diagnosed with mild to moderate obstructive sleep apnea by overnight polysomnography (5$53.7{\pm}16.7$ years, 42 males). REM-dependent OSA was defined as AHI-REM/AHI-NREM ratio>2. We compared clinical and polysomnographic findings between REM-dependent OSA and No REM-dependent OSA patients. Results: Among 56 patients, 37.5% (n=21, average age of $52.3{\pm}19.7$ years, 14 males) met the REM-dependent OSA criteria. There were no significant differences in age, sex and body mass index between two groups. After controlling for age, sex, body mass index and periodic leg movements index, REM-dependent OSA patients showed significantly lower AHI, lower number of oxygen desaturation events and higher stage 2 sleep proportion compared to No REM-dependent OSA patients (p=0.010, p=0.006, p=0.031, respectively). After controlling for age, sex, body mass index and periodic legs movements index, AHI-REM was positively correlated with the number of oxygen desaturation events in REM-dependent OSA group (p=0.002). Conclusion: Current results suggested that 37.5% of patients with mild to moderate severity of obstructive sleep apnea could be classified into REM-dependent OSA. REM-dependent OSA was more common in mild severity of OSA, equally prevalent in both sexes and accompanied with sleep architecture changes, i.e. increased proportion of stage 2. In addition, apneic events during REM sleep in REM-dependent OSA were related to oxygen desaturation.

PURPOSE: To solve the problems of chronic obstructive pulmonary disease (COPD) patients complaining of muscle fatigue and having limited motor abilities, this study provided the clinical basic data for pulmonary rehabilitation by examining the effects of High Low-Frequency Neuromuscular Electrical Stimulation (NMES) on the respiratory muscle strength, quadriceps muscle activity, and life quality. METHODS: Samples were collected from 20 COPD patients and placed randomly in a low-frequency group (n=10) and high-frequency group (n=10). For a pretest, the respiratory muscle strength (MIP, MEP), quadriceps muscle activity (LF, VM, VL), and life quality (SGRQ) were measured. After applying NMES to each group for 30 minutes at a time, five times a week, for four weeks, a posttest was conducted in the same way as the pretest. RESULTS: Both groups showed significant differences in the respiratory muscle strength, quadriceps muscle activity, and quality of life within the groups and there were significant differences in the quadriceps muscle activity between the groups. CONCLUSION: The four-weeks NMES positively influenced the respiratory muscle strength and life quality by enhancing the function of the quadriceps and exercise tolerance. In particular, high-frequency(75 Hz) NMES was more effective than low-frequency (15 Hz) NMES. This result can be an alternative means to improve the physical functions of COPD patients clinically in the future.
