Recovery after lung transplantation (LTx) may be complicated by prolonged mechanical ventilation (MV) and protracted intensive care unit (ICU) stay leading to immobilization and impaired health-related quality of life (HRQoL). In the critical care setting, diaphragm atrophy and weakness have been associated with difficulty weaning from MV, increased risk for readmission to hospital or ICU, and increased mortality. Increasing respiratory muscle strength by inspiratory muscle training (IMT) as part of pre-rehabilitation mitigates respiratory muscle dysfunction peri-operatively and may reduce the risk of post-operative complications. However, IMT is not widely used prior to LTx and the benefits of pre-operative IMT on post-transplant outcomes in LTx candidates have not been studied. Objectives: (1) To evaluate the feasibility of a multicenter randomized clinical trial of IMT in LTx candidates in terms of recruitment rate, retention, program adherence, and outcome ascertainment; (2) To establish the change in pre-transplant dyspnea perception, diaphragm structure and function, health related quality of life (HRQoL) and post-transplant intensive care unit (ICU), hospital and post-transplant 3-month outcomes with IMT relative to usual care group; and (3) To characterize the effect of pre-transplant IMT on peri-transplant diaphragm myofibrillar cross-sectional area (CSA), oxidative capacity, inflammatory markers and post-transplant diaphragm muscle thickness and function (UHN TGH site).
NCT07469280
The purpose of this study is to evaluate the feasibility and effects of a 12-week high-intensity progressive Inspiratory Muscle Training (IMT) program in individuals with Class III obesity (BMI ≥ 40 kg/m²) and obstructive sleep apnea (OSA). Using a single-case experimental design (SCED) with multiple baselines, the study will investigate whether this respiratory intervention can reduce the severity of sleep apnea, as measured by the Apnea-Hypopnea Index (AHI), and improve inspiratory muscle strength and sleep quality. Participants will perform daily training sessions using a resistive loading device (POWERbreathe), with intensity progressing from 40% to 90% of their maximum inspiratory pressure.
NCT07406451
This randomized controlled trial investigated the effects of a four-week inspiratory muscle training (IMT) program on physical and motor performance parameters and shooting accuracy in elite male air pistol athletes. Twenty athletes were randomly assigned to either an IMT group or a control group. Outcome measures included jumping performance, reaction time, flexibility, and shooting accuracy assessed via the SCATT system. The findings demonstrated that IMT significantly improved lower-limb explosive power and shooting performance without affecting reaction time or flexibility.

Bronchiectasis is a chronic respiratory disease clinically characterized by recurrent pulmonary exacerbations, chronic cough, and sputum production, and is associated with an increase in the airway-artery ratio and permanent airway dilatation. It is recognized as the third most common chronic respiratory disease after chronic obstructive pulmonary disease (COPD) and asthma. In the International Classification of Diseases and Related Health Problems (ICD-10), it has its own diagnostic code (J47.9). In bronchiectasis, mucociliary clearance is impaired due to bronchial dilatation, and the insufficient clearance of bacteria and mucus from the respiratory tract leads to persistent infection, inflammation, and further airway damage. Progressive airway damage results in impaired lung function, worsening of symptoms, and, ultimately, respiratory failure and death. It can represent the final pathway of various infectious, allergic, inflammatory, genetic, and degenerative disorders, making it one of the most complex and heterogeneous syndromes. Some patients present with daily symptoms, while others remain asymptomatic except during exacerbations. The most common symptom is chronic cough caused by purulent or mucopurulent sputum. Other symptoms include dyspnea, pleuritic chest pain, wheezing, fatigue, and weight loss. Fever, however, is not a common finding and differs from pneumonia. The most frequently used classification system categorizes bronchiectasis into varicose, cylindrical, and saccular (cystic) types. In the most severe form, the saccular type, the bronchi lose their structural integrity completely, forming cystic structures filled with secretions. The mildest form is cylindrical, in which the bronchi have thick, straight walls. In the varicose type, localized narrowings are observed. Diagnosis is made following history and physical examination, with high-resolution computed tomography (HRCT) being the most sensitive and specific method, along with sputum culture and chest radiography. The goals of bronchiectasis treatment are to manage symptoms, prevent complications, and improve quality of life. Both pharmacological and patient-managed interventions are commonly applied. Pharmacological treatments include antibiotics, bronchodilators, and corticosteroids, which are generally administered via inhalation. Patient-managed interventions require active participation and behavioral modification. Within published guidelines, airway clearance techniques are widely described under pulmonary rehabilitation (PR), but there is no consensus regarding PR itself. For individuals with reduced exercise tolerance, participation in PR and engagement in physical activity are recommended. However, research has shown that referral rates to PR are often low, and exercise and physical activity are not consistently prescribed. Within PR, techniques such as the active cycle of breathing techniques (ACBT), postural drainage, thoracic expansion exercises, and various airway clearance methods are applied, with inspiratory muscle training (IMT) forming an important component. Functional inspiratory muscle training (FIMT) is an IMT program developed by considering not only the ventilatory roles of the respiratory muscles but also their non-respiratory functions. FIMT integrates inspiratory muscle training with core stabilization and postural control exercises. The rhythmic co-contractions of the muscles in the core region support trunk stability and provide the basis for movement. In the first stage of the program, participants receive IMT, and subsequently, core stabilization training and dynamic trunk activation exercises are incorporated into the intervention. A review of the literature reveals that no studies have investigated the effectiveness of FIMT in adults with bronchiectasis. In our study, we aim to evaluate the effects of FIMT, applied in addition to home-based chest physiotherapy, on pulmonary function, diaphragm thickness, balance, core stability, functional capacity, physical activity, posture, and quality of life in adults with bronchiectasis. Furthermore, we aim to compare these outcomes with those of IMT applied alongside home-based chest physiotherapy. We believe that this approach will contribute to the development of treatment strategies in clinical practice and help address existing gaps in the literature.

In this study, a parallel two-group pre-test-post-test randomized controlled trial was conducted according to CONSORT guidelines. All participants and their parents were given detailed information about the study before it commenced, and written informed consent was obtained in accordance with the ethical principles described in the Declaration of Helsinki. Help was received from a third-level athletics coach for planning and implementing running exercises to be used in the project. The study was designed according to the rules of the Declaration of Helsinki and approved by the ethics committee for scientific research of Gümüşhane University (at its meeting on 20.09.2024 and number 2024/7; decision number E-95674917-108.99-282503). The aim of this study is to investigate the effects of additional inspiratory muscle training (IMT) on exercise tolerance, agility performance, and respiratory parameters in 10-12-year-old male football players who have been training regularly for at least two years, based on their chronotype. A power analysis was conducted using G\*Power 3.1 to determine the sample size of the study. The effect size (d) was found to be 1.12 (α = 0.05, 1-β = 0.95, η²p = 0.8). Based on this analysis, it was determined that a minimum of 20 participants per group was required. However, to mitigate potential issues, it was decided to include 25 participants, an additional 25%, in each group. Participants visited the laboratory three times. During the first visit, the familiarization procedure was performed; participants were administered the Morningness-Eveningness Scale for Children questionnaire and divided into 3 groups according to the results. Then, pulmonary function tests (PFT), maximum inspiratory pressure (MIP), expiratory pressure (MEP), six-minute walk test (6MWT), inspiratory muscle training (IMT), and running training procedures were applied. In the second visit, PFT and MIP-MEP tests, agility and 6MWT tests were performed and their performances were recorded. After the six-week training period, participants' final measurements were taken at the third and final visit. Subsequent to the completion of the six-week training period, the participants' final measurements were obtained during the final visit. The experimental trials were conducted at a consistent time each day, between 9:00 and 12:00. Prior to the commencement of the trials, participants were instructed to abstain from high-intensity physical activity. The inclusion criteria were as follows: a) Candidates must have at least two years of active football training, b) be between the ages of 10 and 13, c) be in good general health, d) have no known respiratory or cardiovascular conditions, e) provide written informed parental consent. The following criteria were used to determine exclusion from the study: The subject's medical history includes the following: a) A history of lung disease or a current upper respiratory tract infection, b) A history of current injury, c) Medication use that may affect breathing or performance, d)Individuals with FEV1/FVC\<70 e) Participation in similar studies within the last six months
NCT07001462
Background: Inspiratory muscle training combined with positive expiratory pressure (IMT/PEP) may improve outcomes in chronic obstructive pulmonary disease (COPD), but evidence in exacerbation-prone (Group E) disease is limited. This study is designed to evaluate the effects of IMT/PEP on pulmonary function, respiratory muscle strength, exercise capacity, and dyspnea in stable Group E COPD. Methods : This prospective randomized controlled trial will enroll 62 patients with stable Group E COPD between June 2023 and September 2024. Participants will be randomized to receive IMT/PEP plus standard care or standard care alone. Pulmonary function tests, maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), six-minute walk test (6MWT), oxygen saturation (SO₂), and dyspnea scales (mMRC, CAT, MBS, VAS) will be assessed at baseline, 1 month, and 3 months.

Introduction: After haematopoietic stem cell transplantation (HSCT), patients often experience complications such as respiratory difficulties, fatigue and decreased quality of life. The aim of the study was to compare the effectiveness of different inspiratory muscle training (IMT) protocols on respiratory muscle strength and endurance, dyspnoea, maximal exercise capacity, diaphragmatic function, respiratory function parameters, peripheral muscle strength, fatigue, quality of life, oxidative stress parameters, muscle biomarkers and inflammatory biomarkers in HSCT recipients during the transplantation process. Method: The study will include patients between 18-65 years of age, who are able to walk and understand the instructions, who do not have orthopedic, neurological or cardiac disorders and who will undergo haematopoietic stem cell transplantation. Patients with cognitive impairments; orthopedic or neurological diseases that may affect the evaluation of physical fitness tests; patients with comorbidities such as asthma, COPD will not be included in the study. In cases where the exercise group subjects' attendance to the training protocol is interrupted for 3 sessions or more consecutively, the voluntariness to participate in the research is lost during the research process, and clinical haemodynamic instability develops in the subjects, the participant will be excluded from the study. Patients in whom exercise training is contraindicated such as acute bleeding, haemoglobin value \<5 g/dl, platelet count ≤10000 mm3, high fever (body temperature \>38◦C), severe pain, confusion, dizziness, nausea and vomiting will not be included in the exercise. It is planned as a prospective, randomised controlled and single blinded study. Triple blinding could not be performed due to the executive's evaluation and implementation of the study protocol. Patients included in the study will be randomly divided into 3 study groups of 15 people each. Stratified randomisation technique will be used. A total of 45 haematopoietic stem cell transplant patients will be included in the study. Patients will be evaluated 3 times: before exercise therapy (pre-HSCT), before and after starting the preparatory regime and after exercise therapy (post-HSCT). Primary assessment measures are dyspnoea, maximal exercise capacity, respiratory muscle strength and endurance, diaphragmatic respiration, oxidative stress parameters, inflammatory markers, muscle biomarkers, pulmonary function test. Secondary assessment measures were peripheral muscle strength, fatigue, depression, and quality of life. The research arms consisted of a total of 45(15;15;15) people in 3 groups: 'standard inspiratory muscle training group', 'functional respiratory muscle training group' and 'control group' with 15 people in each group. All patients in the control and research groups will receive inspiratory muscle training for a total of 30 minutes twice a day, every weekday during the transplantation period, starting at the end of the session in which their initial assessment was made. Functional respiratory muscle training group will perform functional exercises simultaneously with inspiratory muscle training 3 days a week (Monday-Wednesday-Friday or Tuesday-Thursday-Saturday). All exercises will be supervised by a physiotherapist. The most important originality of this study is that it is the first study to investigate the effects of functional respiratory muscle training on respiratory parameters, diaphragm function, peripheral muscle strength, maximum oxygen consumption, dyspnoea, fatigue, depression and quality of life in HSCT recipients. It is the first randomised controlled study to demonstrate the effect of inspiratory muscle training on diaphragmatic function in HSCT recipients and it is one of the rare studies in which exercise capacity will be evaluated by cardiopulmonary exercise test. It is also the first study to examine the relationship between inspiratory muscle training and muscle biomarkers and oxidative stress parameters in HSCT recipients. H0: There is no difference in the effectiveness of different inspiratory muscle training protocols on maximal exercise capacity, respiratory muscle strength, respiratory muscle endurance, diaphragmatic function, oxidative stress parameters, muscle biomarkers, inflammatory biomarkers, dyspnoea, peripheral muscle strength, quality of life, fatigue, depression in haematopoietic stem cell transplant recipients. H1: There is a difference in the effectiveness of different inspiratory muscle training protocols on maximal exercise capacity, respiratory muscle strength, respiratory muscle endurance, diaphragmatic function, oxidative stress parameters, muscle biomarkers, inflammatory biomarkers, dyspnoea, peripheral muscle strength, quality of life, fatigue, depression in haematopoietic stem cell transplant recipients.

The aim of this study is to examine the acute effect of the foam roller (FR) method applied to the sternocleidomastoid (SCM) muscle after respiratory muscle fatigue on joint range of motion (ROM), accessory respiratory muscle activity and muscle strength. The aim of this study is to examine the changes in fatigue and pain symptoms by applying relaxation on the tense fascia and shortened muscle as a result of resistance training, and the effect of these changes in the sternocleidomastoid (SCM) muscle on joint range of motion (ROM) and muscle strength in healthy male or female participants aged 18-30. In line with the investigators' results, it may be recommended to add foam roller (FR) to the accessory respiratory muscles in the pulmonary rehabilitation program in patients with chronic lung diseases. For this reason, the investigators think that it will provide clinical and scientific benefits. The investigators believe that it will lead studies to add foam roller (FR) to the pulmonary rehabilitation program in patients with chronic lung diseases. Participants will be informed about the risks and benefits of participating in the study and a voluntary consent form will be signed. Participants will be given a demographic data form before starting the study and will be asked to fill it out. The hypermobility value will be measured according to the Beighton score before the participants start the tests. After the inspiratory muscle training (IMT) study, foam roller (FR) will be applied to the right sternocleidomastoid (SCM) muscle. A one week washout period will be given. Afterwards, the cases will be applied foam roller (FR) to the left sternocleidomastoid (SCM) muscle after the inspiratory muscle training (IMT) study. All evaluation parameters will be repeated before and after the applications. Maximum inspiratory pressure measurement, range of motion (ROM) measurements, muscle strength tests, flexibility with a myotony measuring device, electromyography (EMG) measurements will be made before the study one by one.

Background: The aim of this study was to examine the effect of inspiratory muscle training on respiratory functions, balance and functional capacity in trainable mentally disabled individuals. Methods: Within the scope of the study, 30 children, aged between 8 and 17 years, diagnosed with educable mental disabilities, were randomly divided into experimental and conventional physiotherapy rehabilitation program (CPRP) groups. Before and after the test, blood pressure, respiratory frequency, pulse oximetry heart rate and arterial oxygen saturation (SpO2) values, and Modified Borg scores for fatigue and dyspnea detection were recorded. Body composition analysis, respiratory function test, and 6-minute walk test (6MWT) were performed on all individuals. The experimental group underwent inspiratory muscle training (IMT) with an inspiratory muscle training device 5 days a week for 8 weeks. The CPRP group was given a chest physiotherapy program that included thoracic expansion exercises, postural drainage, cough improvement techniques and physical activity recommendations, to be applied once a day, 5 days a week, for 8 weeks. At the end of eight weeks, the evaluations were repeated. Data were analyzed using SPSS vn. 25.0 software. The Paired Samples t-test was used to determine within-group differences, and Two-way ANOVA was applied to repeated measures to compare time and group effects.

The current "Global Initiative for Chronic Obstructive Lung Diseases" (GOLD) guideline emphasizes that pulmonary rehabilitation should be recommended to all chronic obstructive pulmonary disease (COPD) patients from Stage II onwards. Respiratory muscle training applied to individuals with COPD is an important part of pulmonary rehabilitation due to its benefits such as improving pulmonary function and respiratory muscle strength, reducing the severity of dyspnea, and increasing exercise capacity and quality of life. Although there is sufficient evidence in the literature about the benefits of IMT in individuals with COPD. There is little evidence showing the effects of EMT. Studies show that isolated IMT and EMT are effective in increasing respiratory muscle strength, endurance and exercise capacity. Results from a limited number of studies show that combined training of IMT and EMT is superior compared to isolated IMT or isolated EMT in improving exercise capacity and dyspnea. Incentive spirometers, with their different mechanical properties, are low-cost respiratory exercise devices that are widely used in the early postoperative period, lung diseases, long-term bed rest and in situations where it is necessary to maintain or increase the ventilation ability of the lung, but they do not apply any resistance to the respiratory muscles. In the pulmonary rehabilitation guidelines published by the American Thoracic Society (ATS) and the European Respiratory Society (ERS), the necessity of using devices that apply resistance to the respiratory muscles to strengthen the respiratory muscles is underlined. The personalized respiratory exercise device will be a device that has the clinical features of an incentive spirometer and respiratory muscle training devices (inspiratory and expiratory) and can be personalized according to the desired purpose. With the same device, patients will be able to both improve lung ventilation, such as an incentive spirometer, and strengthen their respiratory muscles.

Proprioceptive weighting changes may explain differences in postural control performance. In addition, the respiratory movement has a disturbing effect on postural balance. Postural balance seems to be impaired in individuals with respiratory disorders. Besides the essential role of respiration, the diaphragm may also play an important role in the control of the trunk and postural balance. Deficits in proprioception are found in a subgroup of patients with low back pain. In addition, disorders of respiration have been identified as strongly related to low back pain. The aim of the study is to clarify whether inspiratory muscle training has a positive effect on proprioceptive postural control in individuals with recurrent low back pain.
