Background: The deep cervical flexor (DCF) muscles have a crucial role in the management of neck pain. For preventing neck pain by activation of the DCF, craniocervical flexion (CCF) is an effective exercise. However, sternocleidomastoid (SCM) muscle is considered to affect negatively the activation of the DCF. SCM muscle which is an accessory muscle for respiration is activated differently depending on types of breathing patterns. It's not certain that breathing patterns affect the SCM and DCF muscles thickness during CCF exercise. Objects: The purpose of this study was to investigate the influence of breathing patterns on the SCM and DCF muscles thickness during CCF exercise. Methods: Forty-five subjects participated in this study, and they were classified according to their breathing pattern, as follows: costodiaphragmatic breathing (CDB) and upper costal breathing (UCB) groups. Ultrasonographic imaging of the SCM and DCF muscles was performed during five incremental levels of CCF during tidal breathing and expiration. Results: There was a significant interaction between the breathing pattern and the phase of CCF for percentage of SCM muscle thickness changes (p<.05). In phase 1 CCF, a percentage of SCM muscle thickness changes was increased in the UCB group than in the CDB group (p<.05). There was an increase in DCF muscles thickness with each additional CCF phase (p<.05). Conclusion: Recruitment of SCM muscle was increased in the UCB group while performing CCF with a low intensity. There were no significant differences on DCF recruitment between the breathing pattern groups. Higher CCF exercise intensities elicited a higher DCF recruitment.

Purpose: The purpose of this study was to examine the effects of the systematic breathing exercise program on recovery of patients with pneumothorax. Methods: An nonequivalent interrupted time-series control group posttest design was used. Participants were 40 inpatients (Experimental Group; 20, Control Group; 20) at the one University Hospital in U city. The systematic breathing exercise program including education on deep breathing exercise using incentive spirometry, Range of motion (ROM) exercise in shoulder joint, walking exercise and feedback were provided to the experimental group, while the control group carried out deep breathing exercise using incentive spirometry. The duration of chest tube insertion, duration of hospitalization, and frequency of analgesics use were measured. The data were analysed by a SPSS/WIN program. Results: The duration of chest tube insertion and duration of hospitalization in the experimental group were significantly shorter than the control group. However, there is no difference of the frequency of analgesics use between the experimental group and control group. Conclusion: The result showed that the systematic breathing exercise program was effective to improve recovery of patients with pneumothorax. This program can be applied in hospitals for patients with pneumothorax as one of the nursing intervention modalities.

Background: Research efforts to improve the pulmonary function of people with limited chest function have focused on the diaphragmatic ability to control breathing pattern. Real-time ultrasonography is appropriate to demonstrate diaphragmatic mechanism during breathing. Objective: The purpose of this study was to investigate the effects of diaphragmatic breathing training using real-time ultrasonographic imaging (RUSI) on the chest function of young females with limited chest mobility. Methods: Twenty-six subjects with limited chest mobility were randomly allocated to the experimental group (EG) and control group (CG) depending on the use of RUSI during diaphragmatic breathing training, with 13 subjects in each group. For both groups, diaphragmatic breathing training was performed for 30-min, including three 10-min sets with a 1-min rest interval. An extra option for the EG was the use of the RUSI during the training. Outcome measures comprised the diaphragmatic excursion range during quiet and deep breathing, pulmonary function (forced vital capacity; FVC, forced expiratory volume in 1-sec; FEV1, tidal volume; TV, and maximal voluntary ventilation; MVV), and chest circumferences at upper, middle, and lower levels. Results: The between-group comparison revealed that the diaphragmatic excursion range during deep breathing, FVC, and middle and lower chest circumferences were greater at post-test and that the changes between the pretest and post-test values were greater in the EG than in the CG (p<.05). In addition, the subjects in the EG showed increased post-test values for all the variables compared with the pretest values, except for TV and MVV (p<.05). In contrast, the subjects in the CG showed significant improvements for the diaphragmatic excursion range during quiet and deep breathings, FVC, FEV1, and middle and lower chest circumferences after the intervention (p<.05). Conclusion: These results indicate that using RUSI during diaphragmatic breathing training might be more beneficial for people with limited chest mobility than when diaphragmatic breathing training is used alone.

최근 치과영역에서 아산화질소(Nitrous Oxide)를 이용한 의식하 진정과 필은 진정의 임상 적용이 증가함에 따라 수술실 또는 진료실 환경이 아산화질소로 오염될 수 있다. 비록 낮은 농도일지라도 장기간 아산화질소에 노출 시 자연유산의 증가, 기형아 출산 증가, 말초신경염 및 운동신경 장애 등과 같은 부작용을 초래하는 것으로 알려져 있다. 호흡시 흡입 공기의 구성성분의 변화를 줄 수 있는 구강 입구로부터 반경 12 inch 이내 영역인 호흡대역(Breathing zone)에서 아산화질소 농도는 치료자에게 영향을 주게된다. 소아 환자에게 주로 적용되는 깊은 진정시는 환자의 구호흡양에 따라서 호흡대역에서 아산화질소의 농도에 영향을 주게되므로, 깊은 진정시 구호흡의 증가 원인을 규명하기 위해 잉여가스 배출 방법을 달리하여 호흡대역에서 아산화질소 농도를 측정 비교하여 다음과 같은 결론을 얻었다. 1. 깊은 진정을 시행하는 경우 호흡대역에서 아산화질소의 농도는 공급 가스량 증가에 의한 비기도 저항 증가에 따라 증가하는 양상을 보였다. 호흡대역에서 아산화질소 농도 증가는 구호흡 증가에 의한 것이며 구호흡은 비기도 저항과 관계가 있다 할 수 있다. 즉 비기도 저항 증가는 구호흡의 한 요인이라 할 수 있다. 음압을 사용한 호기가스 배출장치를 사용하여도 NIOSH에서 권장하는 허용치에는 미치지 못하였고 이를 위해서는 팬이나 다른 제거 장치가 함께 사용되어야 한다. 2. 구강편도의 크기는 기도 저항이 적은 경우 즉 음압을 사용하여 호기가스 제거하는 경우 구호흡에 영향을 주었다.

Purpose: The aim of this study is to suggest an intervention method for clinical use in the future by analyzing the effect of breathing exercise on activity of sternocleidomastoid muscle and scalenus anterior muscle, which are respiratory synergist muscles, and pulmonary functions in patients with forward head posture. Methods: Prior to the experiment, 12 patients (experimental group) performed feedback exhalation exercise along with conventional deep neck exercise, and 11 subjects (control group) performed feedback deep neck exercise along with conventional deep neck exercise. The intervention programs were performed for 40 minutes once a day (three times a week for four weeks). Results: Before intervention, %RMS was measured for surface electromyography (sEMG), and FVC, FEV1, and FEV1/FVC were measured using a spirometer. After four weeks, these items were re-measured under the same condition and analyzed. In within-group comparison of the experimental group, activity of sternocleidomastoid muscle and scalenus anterior muscle showed a significant decrease (p<0.05)(p<0.001), and forced vital capacity (FVC) showed a significant increase (p<0.05). In within-group comparison of the control group, activity of sternocleidomastoid muscle and scalenus anterior muscle showed a significant decrease (p<0.05), and in between-group comparison, there were significant differences in activity of sternocleidomastoid muscle and FVC (p<0.05). Conclusion: Long-term forward head posture restrains exercise performance of the neck and leads to exercise avoidance of the neck during daily activities, thus restraint factors might be created even while breathing. To cut off this link, a constant effort is required and diversified research on the correlation between neck functions and breathing should be conducted.

The aim of this study was to establish a breathing assist system for saxophone players with breathing problems. Although the saxophone is a popular wind instrument with a reed in its mouthpiece, it can be difficult for people with breathing problems to play this instrument, as it requires adequate breath support for deep and even long breaths. To solve this problem, the authors propose a breathing assist device, which functions like a pneumatic master-slave amplifier, for saxophone players with breathing problems. First, the proposed device is fabricated. Second, the effectiveness of the breathing assist device as a master-slave amplifier is confirmed through experiments. Third, the dynamic characteristics of the device are tested up to 10 Hz, and they demonstrate that the device responds well for up to approximately 5 Hz.

호흡은 환자의 상태를 판단하는 중요한 생체 신호 중 하나이다. 특히 진정 마취 시 환자의 무호흡 및 저호흡은 지속적인 모니터링 없이는 탐지하기가 어렵기 때문에 환자의 호흡 상태를 정확하고 간편하게 판단할 수 있는 지속적인 호흡 모니터링 방법이 필요하다. 현재 호흡 상태의 모니터링을 위한 다양한 장치들이 사용되고 있으나 임상 사용단계에서 응답 시간이 느릴 뿐 아니라 사용에 불편한 단점을 안고 있다. 본 연구에서는 이러한 문제점을 해결하고자 PVDF(polyvinylidene fluoride) 필름을 이용한 부착형 센서와 회로를 설계하고 제작하였으며, 진정 마취 시 호흡 신호를 감지하여 이상 호흡 징후를 조기에 발견할 수 있는 알고리즘을 포함하는 모니터링 시스템을 개발하였다. 본 연구의 결과는 진정 마취 시 뿐만 아니라 수면 관련 호흡 상태의 원격진료를 통한 다양한 의료산업 분야에 적용될 수 있을 것이다.

Impaired respiratory function is common in patients with stroke. The purpose of this study were to investigate the effectiveness of exercises and to assess forced vital capacity and peak cough flow after completion of neck stabilizing and respiratory reeducation exercises (combining diaphragmatic breathing and pursed-lip breathing exercises). The 45 participants were randomly assigned to an experimental group 1 ($n_1=15$), experimental group 2 ($n_2=15$), and a control group ($n_3=15$). All subjects performed conservative physical therapy for 30 minutes. Experimental group 1 undertook the neck stabilizing exercise and the respiratory reeducation exercise. Experimental group 2 undertook the respiratory reeducation exercise. Additional exercise did not exceed 30 minutes, five times a week for six weeks. The subjects were assessed for deep neck flexor thickness and breathing function (forced vital capacity, forced expiratory volume at one second, forced expiratory volume at one second/forced vital capacity, peak expiratory flow, and manual assisted peak cough flow) at pre-post value. The results of this study were as follows. Experimental group 1 showed a significant increase only in deep neck flexor thickness change rate (p<.05). All groups showed significant increases in forced vital capacity, forced expiratory volume at one second, and peak expiratory flow in pre-post measurement (p<.05). Experimental groups 1 and 2 showed an increase in manual assisted peak cough flow in pre-post measurement (p<.05). There was no significant difference between experimental group 1 and experimental group 2, but experimental group 1 improved more than experimental group 2 in respiratory function as a whole. In conclusion, these findings suggest that the neck stabilizing exercise in combination with the respiratory reeducation exercise can improve forced vital capacity and peak cough flow in patients with stroke.
