Objective : Respiratory muscle weakness and decreased chest mobility has been suggested to result from the deconditioning that accompanied activity level in chronic elderly stokes. The benefits of respiratory exercise programmes on exercise capacity and muscle strength in hemiplegia. This study aimed to determine the effects of selective inspiratory and expiratory muscles training and chest mobility exercise on patients with strokes to establish if an improved exercise capacity can be obtained in patients that are not limited in their daily activities. Methods & Intervention : Twelve patients were assigned to the intensive respiratory exercise group participated in a measures design that evaluated the subjects with pre-treatment and post-treatment. Thirteen subjects who were assigned to a control group received training with breathing exercise and resistance exercise of skeletal muscles. The subjects performed spirometry then undertook a 6-week programme of respiratory muscle and chest mobility training. Training for the two groups was carried out 2 times a week for 6 weeks. Measurements and Results : Spirometry(Forced Vital Capacity: FVC and Closed Circuit Spiromety: CCS) and thoracic mobility were measured before and after the 6 weeks. The experimental group improved significantly compared to control group in FVC, $FEV_1$, MVV, IRV and ERV, and upper chest wall expansion(p<0.05). No significant improvement was seen in thoracic mobility or lung function in control group(p>0.05). Conclusion : The major findings in this study were that a intensive 6week exercise programme of resistive breathing and chest mobility in patients with hemiplegia led to an increase in lung capacity. The resistive breathing exercise programme used here resulted in a significant increase in the chest excursion during breathing.

본 연구는 호흡 패턴 교정 후, 호흡 동안 흉·복부 둘레 선 세 곳의 운동성(TAMs) 변화와 몸통 전방 굴곡 동안 흉추(TSM) 및 요추부 운동성(LSM)의 변화를 조사하기 위해 수행되었다. 요추부 불안정성이 있는 30명의 대상자들을 15명의 호흡패턴 교정운동 그룹과 15명의 요추부 안정화운동그룹으로 나누어, 한 세션 당 40분 운동, 총 18 세션을 6주 동안 적용하였다. 연구 결과, 호흡패턴교정 그룹은 안정화 운동 그룹에 비해 모든 TAMs과 TSM 이 유의하게 더 증가한 것으로 나타났고 LSM은 더 유의한 감소를 보였다(p<.001). 호흡패턴교정은 전체 TAM(안정호흡: r= .868, 노력성호흡: r= .870) 및 TSM(r= .672)과는 높은 양의 상관관계를, LSM(r= -.420)과는 음의 상관관계를 나타내었다. 본 연구 결과를 기초로, 요추부 불안정성자의 호흡패턴교정이 흉·복부 둘레 선의 상대적 운동성 개선을 통해 흉추와 늑골 관절의 운동성을 촉진하여 몸통 전방 굴곡 시 요추부 굴곡 운동성을 감소시킬 수 있다고 제안한다.

Purpose: The study aims to determine the effect of a breathing exercise on shoulder pain, range of motion (ROM), and forward head posture in patients with rotator cuff repair. Methods: In total, 25 patients with rotator cuff repair were included in this study. The experimental group (n = 13) underwent a breathing exercise, while the control group (n = 12) received traditional physical therapy. The visual analogue scales (VASs) for pain, flexion and abduction ROM, and the craniovertebral angle (CVA) of both groups were recorded at both pre- and post-intervention. Paired t-tests were used to determine significant changes in the post-intervention compared with the pre-intervention period, and independent t-tests were used to analyze differences in dependent variables between the two groups. Results: After the two-week intervention, the experimental group experienced a significantly decreased VAS (p < 0.05) and significantly increased ROM and CVA (p < 0.05), while the control group experienced a significantly decreased VAS (p < 0.05). Further, the experimental group that underwent the breathing exercise showed greater improvements in flexion and abduction ROM and in the CVA than the control group (p < 0.05). Conclusion: The results suggested that a breathing exercise can reduce shoulder pain and enhance ROM and posture in patients with rotator cuff repair.

본 연구는 칼텐본을 접목한 흉추가동운동이 폐기능에 미치는 영향을 알아보기 위하여 20대 대학생 20명을 대상으로 4주간 실시하였다. 실험대상자 20명을 대상으로 실험군, 대조군으로 무작위 동공선택방식으로 그룹 배정을 하였다. 실험군은 횡격막 호흡운동 15분과 칼텐본을 적용한 흉추가동운동 15분으로 구성되고, 대조군은 횡격막 호흡운동으로 30분간 훈련하였으며, 두 군의 운동프로그램은 주 3회 4주간 실시하였다. 측정은 폐기능을 측정하여 자료를 분석하였다. 실험 전·후 폐기능을 분석해 보면, 실험군은 TV, IRV에서 유의하게 증가하였으며, 실험후에 두 집단간의 변화검증에서도 TV와 IRV에서 유의한 차이가 나타났다. 본 연구를 통해 칼텐본을 이용한 흉추가동운동이 폐 기능에 더 긍정적인 효과를 주는 것을 알 수 있었다. 앞으로 임상에서 호흡훈련 시 일반적인 호흡훈련에 흉추가동운동을 함께 접목하는 치료방법이 적극적으로 중재되기를 기대하며 다양한 추가운동프로그램의 개발이 필요할 것으로 사료된다.

Objectives: This study aimed to evaluate the effects of breath-counting meditation (BCM) and deep breathing (DB) on heart rate variability (HRV). These breathing techniques have the characteristics of non-paced and self-controlled breathings, resulting in less increase of HRV. We also compared BCM and DB with usual breathing (UB) or relaxing breathing (RB) which can reveal the characteristics of those. Methods: 83 healthy volunteers sitting in chairs performed non-paced breathing; UB, RB, BCM, and DB each for 5 minutes. One minute of relaxation was permitted between breathings. Participants surfed the internet sitting in front of a computer during UB, while for RB, they remained steady with eyes closed. For BCM, they breathed inwardly counting from 1 to 10 repetitively, while they took a deep breath during DB. Physiological indices were simultaneously recorded with a biofeedback system. Results: Respiration rate, thoracic amplitude, and mean heart rate decreased in RB compared with UB, but there was no change in HRV. Respiration rate in BCM and DB was lower than that in UB or RB, and the amplitude of thorax or abdomen, and HRV all increased (p<0.05). However, mean heart rate and skin conductance decreased in BCM compared with UB (p<0.05), whereas those were no different between DB and UB. Conclusion: BCM, just concentrating mentally on breathing with counting each breath, can increase HRV with less sympathetic activation, while DB, actively moving thorax and abdomen for achieving the deepest respiration rate, can greatly raise HRV with the maintenance of mean vagal or sympathetic tone.

In this paper, we make a study of classification normal from abnormal - normal, asthma through analysis of thoracic sound to take use thoracic sound detection system. Thoracic sound detection system has a function to store thoracic sound and analyze the data. The wave shape of thoracic sound is similar to noise and is systematically generated by inhalation and exhalation breathing, therefore, in this paper, to classify asthma sound in thoracic sound, we could discriminate between normal and abnormal case using level crossing rate(LCR) and spectrogram energy rate.

연구배경 : Airway resistance 측정시 panting 방법은 비정상적인 호흡패턴으로 환자에 따라서는 수행이 어렵고 quiet breathing 방법은 더욱 생리적인 호흡상태하에서 측정이 가능하다. 과거에는 주로 panting을 이용하였으나 최근에는 quiet breathing을 이용하는 추세로 본 연구에서는 panting 및 quiet breathing시에 airway resistance를 측정하여 이를 비교하였다. 방법 : 정상대조군 및 호흡기질환군을 대상으로 유량기량곡선을 측정하고, body plethysmograph를 이용하여 airway resistance를 quiet breathing과 panting시에 각각 측정하였다. 결과: 1) Quiet breathing과 panting시 측정한 airway resistance는 높은 상관관계를 보였다(Raw tot; 0.887, Raw 0.5; 0.921, p<0.05). 2) Panting시 quiet breathing에 비하여 Raw tot는 21.2%. Raw 0.5는 22.1%의 감소율을 보였으며, Inspiratory와 expiratory Resistance의 측정이 가능하였던 경우 Raw insp은 29.3%, Raw exp은 40.6%의 감소율을 보였다. 3) Panting시 airway resistance의 감소율은 호흡기질환군보다 대조군에서 더 컸다. 4) Panting시 specific airway conductance가 유의하게 증가되었으므로 airway resistance의 감소는 thoracic gas volume의 차이와는 관련이 없었다. 5) Panting시 quiet breathing에 비하여 airway resistance가 감소하지 않는 환자는 비교적 airway resistance가 커서 panting을 잘 수행하지 못하는 환자로 추정된다. 결론 : Airway resistance 측정시 환자의 수행능력에 따라 quiet breathing 혹은 panting 방법을 이용할 수 있으나 panting시 quiet breathing보다 결과가 약 20% 감소됨을 고려하여야 하며, 정상군 및 폐질환군에서 panting보다 quiet breathing이 airway resistance를 측정하는 더 좋은 방법으로 생각된다.

The purpose of this study was to investigate the effects that breathing, thoracic and abdominal, had on the smoothness while performing ballet pour de bra. Five skilled ballet dancers(age: $24{\pm}1$, height: $163.4{\pm}2.88$, weight: $44.4{\pm}1.34$) with experience of over 10 years participated in this study. Each participant performed the ballet movement three times with abdominal respiration and with thoracic respiration. The kinematic data was recorded at 60 Hz with three digital cameras (Sony VX-2100). The pour de bra movement consists of two phases, up and down. The up phase is defined as the movement from the en bas through the en avant to the en haut. The down phase is defined as the movement from the en haut through the $\grave{a}$ la seconde to the en bas. During these two phases the Jerk Cost (JC) factor was calculated for the shoulder, elbow and wrist to quantify the smoothness. The group who performed the movement while abdominal respiration had a lower JC factor and so it was concluded that while abdominal respiration the smoothness of the movement was increased as opposed to the thoracic respiration.

Background: This study aimed to determine the effects of training on breathing re-education on pain and dysfunction levels, posture, quality of life (QoL), and pulmonary function in patients. Methods: This study included 34 patients with chronic neck pain and upper thoracic breathing pattern were included. The participants were assigned to either the routine physical therapy program (RPTP) (CG; n=17) or RPTP and breathing pattern re-education training (EG; n=17). The CG and EG groups performed RPTP for 40 minutes, and only the EG groups performed breathing re-education training for 10 minutes. Exercises were performed thrice weekly for both groups. Level of pain and dysfunction, posture, QoL and pulmonary function status were assessed before and after the intervention. Results: After four weeks of intervention, numeric pain rating scale (NPRS), Korean version of neck disability index, cranio-vertebral angle, cranial rotation angle, and 12-item short form health survey-physical and mental component summaries had significant differences before and after intervention in both groups (p<.01). However, only NPRS, forced vital capacity, forced expiratory volume in 1s, and maximum voluntary ventilation showed significant interactions between the two groups and measurement time (p<.01). Conclusion: Breathing re-education training and RPTP may be optimal for patients with chronic neck pain and may be more effective in improving neck pain and pulmonary function.

배경: 비디오 기술의 발전과 내시경의 향상으로 비디오 흉강경수술은 기흉, 다한증 및 종격동 종양 같은 몇 몇 질환에서는 표준 수술로서 인정받고 있다. 이러한 비디오 흉강경수술은 전신마취하에 이중기도관에 의한 일측 폐환기가 필요하였다. 그러나 폐질환이 동반된 환자나 전신상태가 나쁜 고령의 환자와 같은 고위험군 의 경우는 일측 폐환기나 전신마취 자체에 대한 위험성이 높다. 대상 및 방법: 1997년 12월부터 1998년 7월 까지, 전신상태가 나빠서 전신마취가 위험한 8례의 환자를 대상으로(농흉 6례, 난치성 흉수 1례, 간질성 폐섬 유증 1례) 경막외마취하에 자가호흡을 유지한 상태에서 비디오 흉강경을 이용하여 흉강내 질환의 진단 및 치료를 시행하였다. 결과: 7례에서 성공적으로 비디오 흉강경수술이 시행되었다. 수술 도중 호흡기능이 저하 되어 전신마취로 전환한 경우가 1례 있었으나 개흉술로 전환한 경우는 없었다. 만성 농흉 환자 2례의 경우 에서, 1례는 재발하여 다시 비디오 흉강경 배농술을 시행하였으며 1례는 수술 후 7일째 흉곽성형술을 시행 하였다. 수술시간은 평균 31.8$\pm$15.2분이었으며 수술 후 호흡합병증이 발생한 경우는 없었다. 결론: 경막외마 취하에 비디오 흉강경을 통한 진단 및 치료는 고위험군에서 안전하게 시행될 수 있는 기법이라고 사료된다.
