  • Objective: The aim of this study is to explore how using inspiratory training affects the respiratory function and balance of stroke patients. We also plan to compare the results with a control group that does not receive the intervention. Design: A Randomized Controlled Trial Methods: In this study, 27 chronic stroke patients were randomly assigned to either a control group (n=14) or an experimental group (n=13). Both groups underwent six weeks of common interventions involving standard physiotherapy and treadmill training. Additionally, the experimental group received inspiratory training. Respiratory function and balance were evaluated using Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), Maximal Inspiratory Pressure (MIP), Maximal Expiratory Pressure (MEP), Peak Expiratory Flow (PEF), Five times Sit-to-Stand (FTSTS), Seated Center of Pressure (S-COP), and Timed Up and Go (TUG) tests. Results: Respiratory function and balance were compared within each group before and after intervention. The experimental group, which received inspiratory training, showed significant improvements in FVC (0.26±0.18), FEV1 (0.35±0.32), MIP (11.54±12.39), PEF (1.12±1.52), and TUG (-3.39±2.45) compared to pre-intervention values (p<0.05). When comparing changes between groups post-intervention, the experimental group demonstrated significant increases in FVC, FEV1, MIP, PEF, and TUG compared to the control group (p<0.05). However, there were no significant differences in MEP, FTSTS, and S-COP. Conclusions: The results of this study indicate a positive effect of inspiratory training on chronic stroke patients. These findings suggest that with further research involving a larger sample size and enhanced intervention methods, inspiratory training could be employed positively in the rehabilitation of stroke patients.

  • Background: This study was to determine whether the diaphragmatic breathing exercise using a DiP Belt(Diaphragmatic Pressure Belt) is effective in increasing the diaphragmatic motion and forced vital capacity. Design: Pretest-Posttest design. Methods: A total of 44 subjects(15 male, 29 female) participated in this study. All subjects were measured the diaphragmatic motion with a sonography and the Forced Vital Capacity(FVC) was measured with a digital spirometer. After 4 weeks, the subjects were intervened the diaphragmatic breathing exercise using a DiP belt and were remeasured for diaphragm motion and FVC. Results: After exercise intervention, quiet breathing significantly increased with the change in diaphragmatic motion and showed a moderate effect size (p<.01, Cohen's d = -0.53). In addition, it was significantly increased in deep breathing and showed a high effect size (p<.001, Cohen's d = -1.32). The mean diaphragmatic contraction pressure increased, but there was no significant difference and the peak diaphragmatic contraction pressure increased significantly (p<.05). Both diaphragmatic contraction pressure showed small effect sizes (respectively Cohen's d = -0.28, -0.33). In spirometry, FVC, Forced Expiratory Volume in 1 second (FEV1), and FEV1/FVC% all increased, but there was no significant difference. Only peak expiratory flow increased significantly and showed a small effect size (p<.05, Cohen's d = -0.41). Conclusion: The DiP belt diaphragmatic breathing exercise that the principle of visual feedback can correct diaphragm breathing in a short time, so it is a useful breathing exercise device that can help the diaphragm breathing exercise in the right way in clinical practice.

  • Maximal expiratory flow-volume [MEFV] curves were studied in 22 patients who underwent pneumonectomy with various pulmonary lesions, such as lung cancer, bronchiectasis and tuberculosis etc, at the preoperative stage and 3 week, 4 month and 12 month after pneumonectomy for the analysis of the reduction and progressive improvement of postoperative ventilatory function. And the factors affecting them like as age difference and the site of pneumonectomy were also analyzed. From these curves peak flow rate [PF R], maximal expiratory flows at 25% and 50% of expired forced vital capacity [V25, V50] and forced vital capacity [FVC] were obtained. In addition, partial pressure of oxygen and carbon dioxide in arterial blood were measured. The results were as follows; 1. The mixed type, especially obstructive type of ventilatory impairment was observed at 3 week after operation. For 1 year of postpneumonectomy FVC was increased by 12.3% of predicted compared to 2.6% of predicted V50. 2. The improvement of FVC during 1 year of postpneumonectomy showed decreasing tendency with the increase of age but the changes of V25 and V50 were unremarkable. 3. The differences of immediate postoperative reduction and progressive improvement of ventilatory capacity after right and left pneumonectomy were analyzed. The reduction of V50, V25 and FVC at 3 week of postoperation were greater in patients with right pneumonectomy [20.9%, 18.2% and 26.2% of predicted] than in patients with left pneumonectomy 16.5%, 18.2% and 18.1%]. But there was no significant difference of these values at 12 month after pneumonectomy. 4. The partial pressure of oxygen in arterial blood [$PaO_2$] was decreased by 13.6 mmHg at 3 week after pneumonectomy compared to the preoperative stage but returned to the normal range within 4 month after pneumonectomy. However, TEX>$PaCO_2$ was within the normal range during 1 year of postoperation.

  • Objectives : Dyspnea is one of the most common symptoms that we meet, but so far there has been no research about the effects of acupuncture therapy on it. This study was performed in order to evaluate the effect of acupuncture therapy on dyspnea by means of using objective indexes. Methods : The effect of acupuncture therapy was assessed by analyzing the pulmonary function test (PFT) in 10 patients, who had suffered from dyspnea and had pain at the acupuncture point Tian-zong (SI11) when it was compressed by a finger, at our outpatient department. Each patient was treated with acupuncture therapy at both sides of Tian-zong. We compared the results of pre-treatment and post-treatment PFTs, including forced vital capacity (FVC), forced expiratory volume in one second (FEV 1.0), and peak expiratory flow rate (PEFR). Results : FVCs of pre-treatment and post-treatment PFTs were $2.23{\pm}0.34(L)$ and $2.40{\pm}0.36(L)$ respectively (P<0.01). FEV1.0s of pre-treatment and post-treatment PFTs were $1.54{\pm}0.37(L)$ and $1.65{\pm}0.41(L)$ respectively (p<0.05). PEFRs of pre-treatment and post-treatment PFTs were $3.41{\pm}1.26(L)$ and $3.93{\pm}1.42(L)$ respectively (p<0.05). Conclusions From the above data, we conclude that FVC, FEV1.0, and PEFR in dyspneic patients have been improved after acupuncture therapy of Tian-zong, so acupuncture therapy of Tian-zong may relieve the dyspnea symptom.

  • Objectives: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients. Materials and Methods: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR), and ratio of FEV1 to FVC (FEV1/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern. Results: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17-63 years). The mean FVC, FEV1, FEV1/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns. Conclusion: Isolated mandibular fractures presented with abnormal pulmonary function pattern.

  • Purpose: The purpose of this study was to identify the effect of a kinesio tape on inspiratory muscle training(IMT) to improve muscle strength, endurance and pulmonary function. Methods: Healthy 20 males were divided into IMT group (control group) and IMT with tape group (experimental group). The same IMT program was applied to both groups using the Respifit S for four weeks, three times a week, a total 12 times. To exprimental group, kinesio tape was applied on the inspiratory agonist diaphragm and the accessory inspiratory muscle scalene, sternocleidomastoid, pectoralis minor. The inspiratory pulmonary muscle strength was measured by the maximal inspiratory pressure (PI max) and minute volume (MV) using the Respifit S and the pulmonary function were measured peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory volume in 1sec (FEV1), FEV1/FVC using the Spirometer and compared before and after. Results: Results showed that the PI max in the two groups increased significantly and experimental group increased more effectively than that of control group. However, only MV showed a significant increase in experimental group but was not significantly different between the two groups. PEF and FEV1/FVC are significantly increased in both groups, but they did not make much difference between two groups, and the FVC for the two groups did not increase significantly. FEV1 increased significantly only with control group, but did not make a difference with experimental group. Conclusion: These result show that the PI max value for experimental group increased significantly than that of control group. Therefore kinesio tape maximizes inspiratory muscle exercise effect on muscle strength improvement. However, because of the short experimental period and difficulty in subject control, increase values of the others did not show a significant difference. In other words, kinesio tape did not show maximizing the inspiratory muscle exercise effect to improve endurance and pulmonary function.
