RESUMO
Aim: Nurses are well-qualified to deliver integrative complementary therapy interventions, a holistic approach to assist individuals experiencing anxiety and stress. Self-regulated, controlled breathing exercises (a clinical approach) are reported to decrease anxiety and increase stress tolerance. The aim of this systematic review was to evaluate the effectiveness of breathing exercise interventions on the psychological and physiologic outcomes of anxiety and stress among adults and assess the state of the science in the post-COVID-19 population. Methods: A systematic review was conducted, and four scientific databases were searched: PubMed, CINAHL, EMBASE, and Web of Science. Inclusion criteria included: (1) peer-reviewed studies, (2) adults over 18, (3) breathing exercise interventions, and (4) anxiety or stress as outcomes. Results: Out of 309 studies identified, 19 were included. Twelve reported significant improvements in anxiety and nine reported significant improvements in stress following varying breathing exercise interventions (p < .05). No adverse events were reported. Conclusions: Breathing exercises were found to be effective in reducing anxiety and stress in adults, however, there continues to be limited evidence that includes large randomized controlled trials. Breathing exercises are a holistic care approach that can be safely implemented by nurses to decrease symptomatology among adults, including the post-COVID population.
RESUMO
Objective: Head-down training can affect behavioural and neurocognitive control while performing dual tasks (DT). Breathing training improves motor and cognitive performance in patients with chronic obstructive pulmonary disease (COPD). As a neurorehabilitation tool, functional near-infrared spectroscopy (fNIRS) has been demonstrated to be an effective method for detecting changes in brain activation during motor recovery, as well as monitoring patients' long-term progress during DT in motor and cognitive performance. However, no studies have examined the combined effect of head-down position and breathing exercises on motor and cognitive performance during DT. This study will employ a novel intervention involving head-down strong abdominal breathing training to investigate its effects on motor and cognitive performance during DT in patients with COPD aiming to inform future training modalities in the community and at home. Methods: We will recruit participants from Anqing, China, through community announcements, bulletin board postings, WeChat, and offline visits and screen 72 patients with stable COPD, classified as Global Initiative for Chronic Obstructive Lung Disease (GOLD) I-II, by pulmonologists at the university hospital. All participants will be randomly assigned to the head-down strong abdominal breathing (tilt angle 0-30° on the inversion apparatus, respiratory rate 20-30 breaths/min), head-down training, and strong abdominal breathing training groups in a 1:1:1 ratio. The intervention will last 12 weeks, with sessions performed thrice weekly for 1 h. Results: The primary outcomes will be motor-cognitive DT time, dual-task effects, correct responses to cognitive tasks, and gait characteristics assessed at baseline, 6 and 12 weeks of intervention. The patient's dorsolateral prefrontal cortex (PFC) will also be stimulated with fNIRS at wavelengths of 730 and 850 nm, with a sampling rate of 11 Hz, to record oxy-haemoglobin (oxy-Hb), deoxy-haemoglobin (deoxy-Hb), and total oxyhaemoglobin (total-Hb). Secondary outcomes will include pre- and post-intervention scales for dyspnoea, overall cognitive function, balance, and anxiety and depression. Conclusion: Alterations in the PFC involved in attentional control, planning, and decision-making may partially explain cognitive and motor deficits (such as impaired balance and slower walking speed) in patients with COPD. This study may help to understand the effects of head-down strong abdominal breathing training on cognitive and motor performance under DT in patients with COPD and compare it with head-down training and breathing training alone. It may also help to determine whether it is a simple and effective form of exercise at home and in the community.
RESUMO
Background: Postoperative recovery in lung cancer patients is a complex process, where breathing exercises may play a crucial role in enhancing pulmonary function and quality of life (QoL). This study systematically reviews and meta-analyzes the impact of breathing exercises on post-surgical lung function and QoL in lung cancer patients. Methods: An extensive literature search was conducted across PubMed, Cochrane, Web of Science, and Embase databases using terms like "Lung Neoplasms", "breathing exercises", and "randomized controlled trial", supplemented by Medical Subject Headings (MeSH) and free words. The Cochrane risk of bias tool was used for quality assessment. A systematic review and meta-analysis on the effects of breathing exercises post-lung cancer surgery followed by data extraction and quality evaluation. Results: From 384 retrieved studies, 10 met the inclusion criteria and were selected for detailed analysis. The main outcomes assessed were postoperative pulmonary function indices and QoL measures. The majority of studies were deemed 'low risk' for random sequence generation and allocation concealment. However, due to the nature of the interventions, blinding was a 'high risk' in most cases. The meta-analysis revealed significant improvements in key pulmonary function indices: forced vital capacity (FVC%) increased by an average of 1.73%, maximal voluntary ventilation (MVV) improved by 7.58 L/min, and maximal inspiratory pressure (MIP) enhanced by 0.95 cmH2O. Additionally, there was a notable alleviation of postoperative dyspnea and an enhancement in QoL, with anxiety scores decreasing by an average of 3.42 points and complication rates reducing correspondingly. However, the interventions did not significantly affect physical activity levels or performance on the 6-minute walk test (6WMT), with effect sizes for these outcomes being non-significant. Conclusions: This study indicates that breathing exercises significantly improve postoperative pulmonary function and QoL in lung cancer patients. Future research should delve into the mechanisms behind these exercises and evaluate their long-term rehabilitation effects. Customized programs could further optimize recovery and enhance patient QoL.
RESUMO
BACKGROUND: Exercise is a first-line treatment for chronic non-specific low back pain (CNSLBP). Exercise combined with specific breathing techniques have the potential to improve multifactorial outcomes. No previous studies, however, have compared outcomes between identical exercises with or without a specific breathing protocol in a uniform clinical study setting. OBJECTIVES: 1) To investigate the feasibility of combining synchronized breathing with movement control exercises and evaluate eligibility criteria, randomization procedures, and dropout rates. 2) To study the preliminary efficacy of the interventions on multifactorial outcome measures. METHODS: Thirty subjects with CNSLBP were randomized into two groups. Both groups had four contact clinic visits where they received personalized home movement control exercises to practice over two months. The experimental group included a movement control exercise intervention combined with synchronized breathing techniques. Trial registration number: NCT05268822. RESULTS: Feasibility was demonstrated by meeting the recruitment goal of 30 subjects within the pre-specified timeframe with enrolment rate of 24.8% (30/121). Synchronized breathing techniques were successfully adhered by participants. Home exercise adherence was nearly identical between the groups without any adverse events. Preliminary efficacy findings on pain intensity, disability, and self-efficacy in the experimental group exceeded the minimal clinically important difference. No such findings were observed in any outcome measures within the control group. Overall, multifactorial differences were consistent because nine out of eleven outcome measures showed greater improvements for the experimental group. CONCLUSION: The synchronized breathing with movement control exercises protocol was feasible and may be more beneficial for improving multifactorial outcomes compared to identical exercises alone. Results suggested progression to a full-scale trial.
RESUMO
BACKGROUND: To carry out their victim rescue and fire-fighting missions, firefighters perform high levels of physical exertion and among them strenuous muscular activity. A specific mental preparation protocol that could induce better strength performance throughout their 24-hour schedule is a major issue for firefighters. OBJECTIVE: This case report aims to examine whether a 6-minute Intervention combining mental imagery practices and breathing exercises, specifically designed to be used while travelling between the fire station and the mission site, would be able to promote maximum strength performance. METHODS: A series of three Single Case Experimental Designs (SCED) was conducted in single blind design to investigate the effects of repeated challenge-withdrawals between the Intervention and the Baseline on the maximum voluntary isometric contraction (MVIC) strength of the hand-grip. RESULTS: Data analyses revealed that 62.5% to 100% of the hand-grip strength values during the Intervention periods were greater than or equal to the maximum data point recorded in the Baseline periods. The effect sizes of these highlighted increases of the hand-grip strength performance revealed by the percentage of non-overlapping data (PND) were 75% i.e., moderately effective on average. CONCLUSIONS: Such a "psyching-up" practice before an upcoming muscular activity can promote muscular strength in firefighters. These results have led French firefighter departments to integrate the teaching of these practices into the initial instruction of firefighters, and remains to be confirmed by a randomised control trial.
RESUMO
Introduction: The aim of the present study was to determine the effectiveness of simultaneous bilateral visual diaphragm biofeedback (BFB) from ultrasonography in conjunction with inspiratory muscle training (IMT) on diaphragmatic thickness during normal breathing and respiratory and clinical outcomes in patients with non-specific low back pain (NSLBP) and determine the influence of age and sex. Methods: A single-blind randomized clinical trial was carried out (NCT04582812). A total sample of 96 patients with NSLBP was recruited and randomized by sex-based stratification into IMT (n = 48) and BFB + IMT (n = 48) interventions over 8 weeks. Bilateral diaphragmatic thickness at maximum inspiration (Tins) and expiration (Texp), respiratory pressures, lung function, pain intensity, bilateral pressure pain threshold (PPT), disability, and quality of life were measured at baseline and after 8 weeks. Results: The BFB + IMT group showed significant differences (p < 0.05) with increased left hemidiaphragm thickness at Tins and Tins-exp (d = 0.38-053), and right and left PPT (d = 0.71-0.74) versus the IMT group. The interaction with sex was statistically significant (p = 0.007; F(1,81) = 7.756; ηp 2 = 0.087) and higher left hemidiaphragm thickness at Tins was predicted by the BFB + IMT group (R 2 = 0.099; ß = 0.050; F(1,82) = 8.997; p = 0.004) and male sex (R 2 = 0.079; ß = 0.045; F(1,81) = 7.756;p = 0.007). Furthermore, greater left hemidiaphragm thickness at Tins-exp was predicted by younger age (R 2 = 0.052; ß = -0.001; F(1,82) = 4.540; p = 0.036). Discussion: The simultaneous bilateral visual diaphragm biofeedback by ultrasonography in conjunction with IMT was effective in both increasing the left diaphragmatic thickness during inspiration, which was positively influenced and predicted by male sex and younger age, and increasing the bilateral PPT of the paraspinal muscles in patients with NSLBP.
RESUMO
OBJECTIVE: Older adults with asthma (OAA) have elevated asthma morbidity rates. A six-session intervention based on self-regulation theory was shown to improve outcomes. However, wide-spread implementation was difficult due to the in-person design. Our objective was to determine the feasibility and acceptability of an updated intervention for OAA that is completely remote, includes a physician component, and utilizes shared decision-making (SDM). METHODS: A pilot study of 12 OAA with uncontrolled asthma and their asthma providers was conducted at three health centers. The remote intervention (titled SOAR) consisted of 4 sessions (2 groups and 2 individual). Asthma providers (both specialists and primary care) were sent updates of progress along with information on how to incorporate SDM into the visit. Implementation (feasibility, acceptability, and appropriateness) and clinical (asthma control, asthma quality of life, perceived control, depression, and self-confidence) outcomes were measured. RESULTS: SOAR was found to be feasible, acceptable, and appropriate, with values on validated implementation scales similar to those of in-person behavioral interventions. Asthma providers found the program helpful and intended to change care based on the updates. Asthma control scores improved significantly from baseline (14.2 to 16.8, p = 0.04), as did asthma quality of life (4.2 to 4.9, p = 0.03) and self-confidence to manage asthma (7.1 to 8.5, p = 0.02). There was no change in depression nor perceived control scores. CONCLUSION: A remote behavioral intervention appeared feasible and acceptable for OAA and their health care providers, and can improve outcomes. Larger scale implementation trials are warranted.
RESUMO
Objectives: To present a simple form of vocal and breathing conditioning for voice professionals based on concepts from vocal science. The vocal conditioning program called Voice Athletes Conditioning uses the principles of exercise physiology to gradually improve vocal and respiratory overload to achieve endurance, power, and flexibility. Methods: Due to our personal experience with high voice users, we synthesized a vocal conditioning program (AVCP) that combines voice science, exercise physiology, sports science and physical therapy principles. This is an 8-week program of daily vocal and breathing exercises with overload enhancement each week using different types of breathing devices and semi-occluded vocal tract exercises, designed and developed according to the specific requirements and performance of the voice professional. Reflections: Professional voice users often experience episodes of vocal fatigue that can directly affect their performance and vocal health. As with physical training for athletes, voice exercises can also contribute to improving vocal conditioning, preventing voice disorders, as well as helping to obtain better performance, greater tolerance to fatigue and shorter recovery time. Conclusions: AVCP is an approach that considers the principles of muscle training aimed objectively at the respiratory and vocal muscles, carried out with a variety of breathing devices and specific vocal exercises in search of greater performance time, less physiological stress, and shorter recovery time in the professional use of the voice.
Objetivos: Presentar una forma sencilla de acondicionamiento vocal y respiratorio para profesionales de la voz, basada en conceptos de la ciencia vocal. El programa de acondicionamiento vocal denominado Voice Athletes Conditioning utiliza los principios de la fisiología del ejercicio para mejorar gradualmente la sobrecarga vocal y respiratoria, con el fin de lograr resistencia, potencia y flexibilidad. Métodos: Debido a nuestra experiencia personal con usuarios de voz aguda, sintetizamos un programa de acondicionamiento vocal (AVCP) que combina principios de la ciencia de la voz, la fisiología del ejercicio, las ciencias del deporte y la fisioterapia. Se trata de un programa de 8 semanas de ejercicios vocales y respiratorios diarios con realce de sobrecarga cada semana utilizando diferentes tipos de dispositivos respiratorios y ejercicios semioclusivos del tracto vocal, diseñado y desarrollado de acuerdo con los requerimientos específicos y el rendimiento del profesional de la voz. Reflexiones: Los usuarios profesionales de la voz experimentan a menudo episodios de fatiga vocal que pueden afectar directamente su rendimiento y salud vocal. Al igual que ocurre con el entrenamiento físico de los deportistas, los ejercicios vocales también pueden contribuir a mejorar el acondicionamiento vocal, prevenir trastornos de la voz, además de ayudar a obtener un mejor rendimiento, una mayor tolerancia a la fatiga y un menor tiempo de recuperación. Conclusiones: El AVCP es un enfoque que considera los principios del entrenamiento muscular dirigido objetivamente a la musculatura respiratoria y vocal, realizado con diversos aparatos respiratorios y ejercicios vocales específicos en busca de un mayor tiempo de actuación, menor estrés fisiológico y menor tiempo de recuperación en el uso profesional de la voz.
RESUMO
PURPOSE: This study was designed to synthesize the efficacy and safety of breathing exercises in interstitial lung disease (ILD) patients by reviewing the literature and comparing the impact of different control group types, ILD subtypes, breathing exercise action modes or methods, and intervention durations on clinical efficacy. METHODS: Systematic searches were conducted across 9 electronic databases, including PubMed, to retrieve English and Chinese studies reporting on ILD patients from inception to February 12, 2024. Study selection and data extraction were independently conducted by two researchers. The quality of the included studies was assessed using the Cochrane risk of bias tool. The data were analysed using RevMan 5.4 and STATA 17.0 software. RESULTS: The search identified 25 studies. Compared to the control group, the breathing exercise group exhibited significantly improved lung function (FVC%pred: MD = 3.46, 95%CI = 1.04 to 5.88; DLCO%pred: MD = 3.20, 95% CI = 2.91 to 3.48), dyspnoea (MRC or mMRC scale: MD = - 0.50, 95%CI = - 0.77 to - 0.22), exercise capacity (6MWD: MD = 32.65, 95% CI = 14.77 to 50.53), and HRQoL (SGRQ: MD = - 6.53, 95% CI = - 8.72 to - 4.34) in ILD patients. According to the subgroup analysis, significant improvements consistent with the overall results were observed in the control group with usual treatment. Compared with the control group, breathing exercises had varying degrees of improvement in the mixed diagnostic group, known-cause group, and fibrotic group of ILD patients; breathing exercises alone significantly improved DLCO%pred, MRC (or mMRC), and SGRQ; and the improvement in breathing exercises as part of pulmonary rehabilitation (PR) was more notable. Different durations of breathing exercise could promote the efficacy of different aspects of treatment for ILD patients. CONCLUSIONS: Compared with usual treatment, breathing exercises can improve lung function, exercise capacity, and HRQoL in ILD patients, particularly without high requirements for intervention duration. The efficacy of breathing exercises varies for different ILD subtypes, and incorporating breathing exercises as part of PR can be more beneficial for ILD patients. No studies have shown significant risks for ILD patients engaging in breathing exercises.
RESUMO
BACKGROUND: Age-related thoracic kyphosis can impair posture, diaphragmatic excursion, respiratory function, and overall quality of life (QoL). PURPOSE: This randomized controlled trial aimed to compare the effects of corrective exercises alone versus combined with diaphragmatic breathing exercises on thoracic kyphosis, diaphragmatic excursion, thoracic pain, and QoL in postmenopausal kyphotic women. METHODS: Forty postmenopausal women diagnosed with thoracic kyphosis were randomly divided into two groups. Group A received corrective exercises for 12 weeks (n = 20), while Group B received both diaphragmatic breathing exercises and corrective exercises for the same duration (n = 20). Primary outcome measures were thoracic kyphosis angle and diaphragmatic excursion, while secondary outcome measures were thoracic pain and QoL. Both groups were assessed pre- and post-intervention using a flexible curve ruler for the thoracic kyphosis angle, ultrasonography for the diaphragmatic excursion, the visual analog scale for thoracic pain, and the Arabic version of the QoL Questionnaire of the European Foundation for Osteoporosis for QoL. RESULTS: Both groups showed significant within-group improvements in all measures post-intervention (p < 0.05). Between-group comparisons post-intervention revealed no significant differences (p > 0.05) except for diaphragmatic excursion, where Group B showed significantly greater improvement (p < 0.05). CONCLUSIONS: A 12-week program of corrective exercises alone or combined with diaphragmatic breathing exercises significantly improved kyphosis angle, thoracic pain, and QoL in postmenopausal kyphotic women. The addition of diaphragmatic breathing exercises provided further benefits by increasing diaphragmatic excursion to a greater degree compared with corrective exercises alone.

OBJECTIVES: To compare vascular scanning parameters (vessel diameter, peak systolic velocity, end-diastolic velocity, and resistive index) and scanning time before and after breathing control training program for selected abdominal vessels. METHODS: This study was pre and post quasi-experimental. The researchers designed a breathing training program that gives participants instructions through a video describing breathing maneuvers. Data were collected at the ultrasound laboratory/College of Health and Rehabilitation Sciences in Princess Nourah bint Abdul Rahman University, Riyadh, Saudi Arabia from January 2023 to November 2023. About 49 volunteers at the university participated in the study. Scanning was performed two times for the right renal artery, upper abdominal aorta, inferior vena cava, and superior mesenteric artery. Scanning time was measured before and after the program as well. A paired sample t-test was used to compare the parameters means and time before and after the program. RESULTS: The program had a significant effect on the following parameters: right renal artery peak systolic velocity (p=0.042), upper abdominal aortic peak systolic velocity, and resistive index (p=0.014, p=0.014 respectively), superior mesenteric artery and inferior vena cava diameters (p=0.010 and p=0.020). The scanning time was reduced significantly (p<0.001). CONCLUSION: The breathing training program saves time and improves ultrasound measurement quality. Hospitals and health centers should consider the importance of breathing control training programs before abdominal scanning.

Introduction: Hypopressive exercise (HE) can be viewed as a mind-body activity, characterized by the integration of breath control and stretching postures. Proponents of HE claim that this type of training can offer potential therapeutic or health benefits. To date, there is no existing comprehensive published overview on HE. This scoping review aims to map and summarize the current literature reporting data on HE and identify key knowledge gaps and future research directions. Methods: This review considered studies that report on the immediate, short-, or long-term practice of HE regardless of condition, sex, age, and/or level of practice or physical condition. Any context or setting was considered for inclusion. This review was performed in accordance with the methodological framework proposed by the Joanna Briggs Institute and by Arksey and O'Malley. MEDLINE, CINAHL, SPORTDiscus, Scopus, and Web of Science were searched from inception up to July 2023. Literature was mapped following the Patterns-Advances-Gaps-Evidence for Practice Recommendations framework to identify patterns and inform practice. Results: In total, 87 studies were identified that reported on the following themes: (1) therapeutic application of a short- or long-term HE programs (n = 56); (2) physiologic and physical responsiveness to a short- or long-term HE programs (n = 22); (3) psychologic and behavioral response to a short-term HE program (n = 14); and (4) acute or immediate physiological responses (n = 21). Literature gaps included poor methodological design, incomplete reporting of intervention, lack of male participants, and exploration of muscle groups distinct from the pelvic floor and abdominal muscles. Discussion: There is a need for high-quality randomized controlled trials, adherence to reporting guidelines on exercise, and the use of active control groups to verify clinical significance, the dose response, and health applications of HE.
RESUMO
Cherubism, a rare autosomal dominant disorder, presents with symmetrical, painless jaw extension due to fibrous tissue ossification, often referred to as hereditary fibrous dysplasia of the jaw. It typically manifests with progressive mandibular and maxillary swelling from childhood to adolescence, with exacerbation over time. A 20-year-old male presented with facial and jaw swelling, causing restricted jaw movements. Computed tomography confirmed the cherubism diagnosis. Subsequently, the patient underwent oral surgery for bone shaving and shaping. Post-surgery, a five-week physiotherapy regimen was initiated, emphasizing joint mobility preservation through active range-of-motion exercises and proprioceptive neuromuscular facilitation for facial expression and dyspnea alleviation. Following physiotherapy, significant improvements were observed, including enhanced respiratory function, increased cervical muscle strength, improved respiratory clearance, and reduced anxiety and depression levels. This case highlights the importance of physiotherapy in cherubism rehabilitation, a novel approach deserving further exploration.
RESUMO
OBJECTIVE: Aim: To determine the dynamics of renewal of the function of external respiration in patients after laparoscopic cholecystectomy at the acute stage of rehabilitation under the influence of a rehabilitation program. PATIENTS AND METHODS: Materials and Methods: The study is randomized, simple with blinded assessors. The forced vital capacity (FVC, l), forced expiratory volume in the first second (FEV1, l) and peak expiratory flow rate (PEFR, l/s) were assessed. Spirometry was performed 120 patients on the first day of admission of patients to the surgical department for surgical intervention, on the second day and on the day of discharge. Methods of mathematical statistics: arithmetic mean (M) and standard error of the mean (}m), Student's t-test were calculated, differences at p<0,05 were considered statistically significant. RESULTS: Results: It has been established that laparoscopic cholecystectomy leads to a statistically significant decrease in the parameters of respiratory function in all age categories. More pronounced positive dynamics of respiratory function in the group of respiratory therapy. It was established that without respiratory therapy on the day of discharge there was no restoration (Ñ<0.05) in groups of elderly patients of group of FVC l, FEV1 l, PEFR l/s; in middle-aged patients did no restoration FEV1, l, PEFR, l/s; in younger patients there was no recovery of FEV1, l. CONCLUSION: Conclusions: The results of the study indicate the effectiveness of the introduction of diaphragmatic breathing exercises in combination with early mobilization at the acute and subacute stages of rehabilitation in patients after laparoscopic cholecystectomy in order to restore the function of the respiratory system.

Objectives: The aim of this study was to investigate the effect of diaphragmatic breathing training with visual biofeedback on respiratory function in patients with multiple rib fractures. Patients and methods: Between June 2021 and October 2021, a total of 16 patients (15 males, 1 female; mean age: 49.50±11.85 years; range, 25 to 66 years) who were diagnosed with multiple rib fractures were randomly assigned into two groups as the control group (CG, n=8) and the visual biofeedback group (VBG, n=8). The effect of each diaphragmatic breathing training on respiratory function was evaluated before and after eight interventions. For respiratory function, pulmonary function test was used to measure pulmonary function and respiratory muscle strength, and the Pain, Inspiratory capacity, Cough (PIC) score was used to evaluated pain, inspiratory capacity, and cough ability. Results: In both groups, the pulmonary function representing the ratio of measurements to predicted values of both forced vital capacity (CG mean difference=25.37±4.58, p=0.002, VBG mean difference=24.25±3.96, p=0.007) and forced expiratory volume in 1 sec (CG mean difference=32.38±5.7, p=0.002, VBG mean difference=26.15±5.73, p <0.001) increased significantly. The maximal inspiratory (CG mean difference=14.00±0.35, p=0.002, VBG mean difference=20.5±6.26, p=0.009) and expiratory pressure (CG mean difference=43.72±29.44, p=0.034, VBG mean difference=25.76±6.78, p=0.015), the indicators of respiratory muscle strength, increased significantly in both groups. The PIC score, which evaluated pain, inspiratory capacity, and cough ability, also increased significantly in both groups (CG mean difference=1.63±0.26, p≤0.001, VBG mean difference=3.13±0.19, p <0.001). The change of PIC score after intervention did not significantly differ between the groups (F=1.439, p=0.250); however, there was a significant difference over time (F=38.476, p <0.001). The change of PIC scores differed over time between the groups (F=2.806 p=0.011). Conclusion: Diaphragmatic breathing training and diaphragmatic breathing training with visual biofeedback can improve pulmonary function, respiratory muscle strength, pain, inspiratory capacity, and cough ability in patients with multiple rib fractures.
RESUMO
BACKGROUND: Stress is an emotional response caused by external triggers and is a high-prevalence global problem affecting mental and physical health. Several different digital therapeutic solutions are effective for stress management. However, there is limited understanding of the association between relaxation components and stress levels when using a digital app. OBJECTIVE: This study investigated the contribution of relaxation tools to stress levels over time. We hypothesized that participation in breathing exercises and cognitive behavioral therapy-based video sessions would be associated with a reduction in stress levels. We also hypothesized a significant reduction specifically in participants' perceived sense of burden and lack of productivity when engaged with breathing exercises and video sessions. METHODS: Stress levels were evaluated in a real-world data cohort using a behavioral health app for digital intervention and monitoring change. This retrospective real-world analysis of users on a mobile platform-based treatment followed users (N=490) who started with moderate and above levels of stress and completed at least 2 stress assessments. The levels of stress were tracked throughout the first 10 weeks. A piecewise mixed effects model was applied to model the trajectories of weekly stress mean scores in 2 time segments (1-6 weeks and 6-10 weeks). Next, a simple slope analysis was used for interpreting interactions probing the moderators: breathing exercises and video sessions. Piecewise mixed-effects models were also used to model the trajectories of specific perceived stress item rates in the stress questionnaire in the 2 segments (1-6 weeks and 6-10 weeks) and whether they are moderated by the relaxation engagements. Simple slope analysis was also used here for the interpretation of the interactions. RESULTS: Analysis revealed a significant decrease in stress symptoms (ß=-.25; 95% CI -0.32 to -0.17; P<.001) during the period of 1-6 weeks of app use that was maintained during the period of 6-10 weeks. Breathing exercises significantly moderated the reduction in stress symptoms during the period of 1-6 weeks (ß=-.07; 95% CI -0.13 to -0.01; P=.03), while engagement in digital video sessions did not moderate stress scores. Engagement in digital video sessions, as well as breathing exercises, significantly moderated the reduction in perceived sense of burden and lack of productivity during weeks 1-6 and remained stable during weeks 6-10 on both items. CONCLUSIONS: This study sheds light on the association between stress level reduction and specific components of engagement in a digital health app, breathing exercises, and cognitive behavioral therapy-based video sessions. Our findings provide a basis for further investigation of current and moderating factors that contribute to the personalization of digital intervention. In addition, results may aid in developing a more comprehensive understanding of how digital intervention tools work for mental health and for whom they are most effective.
RESUMO
A polar plunge is a term referring to an ice-cold water immersion (CWI), usually in the winter period. It is also a part of a specific training program (STP) which currently gains popularity worldwide and was proven to display paradigm-shifting characteristics. The aim of this study was to compare the indices of mental functioning (including depression, anxiety, mindfulness) and duration of upper respiratory tract infection (URTI) measured among the study participants. A set of questionnaires was distributed via the Internet. Participants declaring regular STP practice were selected (N = 77). Two groups were matched based on a case-control principle: the first one (the control group) comprised participants who did not declare nor CWI practice, nor STP practice. The second one comprised participants declaring regular CWI practice only. The CWI only group displayed better mental health indices and shorter URTIs compared to the control group. Moreover, the STP group also displayed better general mental health, less somatic complaints, and shorter URTIs compared to the CWI only group. This study suggests the existence of CWI's potential in boosting mental health and immune system functioning, however when complemented by a specific breathwork, this potential can be increased. However, further research is required.

In this educational landscape, the pervasive issue of stress among higher secondary students has emerged as a serious matter. Acknowledging the challenges posed by educational stress, this research explores holistic and accessible interventions, with a focus on the promising avenue of deep breathing exercises known for their effectiveness in promoting relaxation and reducing stress. The study employs a quasi-experimental design, comparing an experimental group engaged in daily deep breathing exercises with a control group following a regular routine. Sixty higher secondary students in Visnagar participate through purposive sampling, adhering to specific inclusion criteria. The intervention includes a pre-tested questionnaire to assess stress levels, the implementation of daily deep breathing exercises in the experimental group, and a post-intervention stress level reassessment in both groups. The findings reveal a notable reduction in stress levels post-intervention, particularly in the experimental group practicing deep breathing exercises. Statistically significant reductions in mean stress scores underscore the effectiveness of this intervention, with the experimental group demonstrating a significantly lower mean stress score compared to the control group. This study contributes vital insights into stress management strategies for higher secondary students, highlighting the efficacy of incorporating deep breathing exercises into their routine. The observed reductions in stress levels emphasize the potential benefits of practical stress reduction techniques within the educational milieu.
RESUMO
Background: An intricate physiological and pathophysiological connection exists between the heart and lungs, which is especially important in individuals with spinal cord injury (SCI). While an exercise intervention may seem the best approach to leverage this relationship, the prior work has shown that, despite numerous health benefits, regular exercise training does not improve cardiorespiratory control in individuals with SCI. Breath training presents an alternative intervention that is uniquely accessible, with yogic breathing directly engaging linked fluctuations in respiration and cardiovascular control. In addition, there is evidence across a range of populations that regular yogic breathing reduces cardiovascular disease risk. It is possible that the chronic decrease in breathing frequency associated with regular yogic breathing, rather than the specific yogic breathing techniques themselves, is the primary contributor to the observed risk reduction. Methods: Therefore, in 12 individuals with traumatic SCI from C4 to T8, the authors compared Unpaced and conventional 0.083 Hz (Slow) paced breathing with various yogic breathing techniques including: (1) inspiratory-expiratory breath holds (i.e., Kumbhaka or "Box Breathing"), (2) extended exhalation (1:2 duty cycle), and (3) expiratory resistance via throat constriction (i.e., Ujjayi). Beat-to-beat heart rate and blood pressure were measured as well as end-tidal CO2 and O2 saturation were measured. Statistical analysis was performed using a one-way repeated-measures analysis of variance with post hoc pairwise t tests corrected for multiple comparisons. Results: As expected, all slow breathing patterns markedly increased respiratory sinus arrhythmia (RSA) compared with Unpaced in all (n = 12) individuals. More importantly, Ujjayi breathing appeared to improve ventilatory efficiency over Unpaced breathing in individuals with SCI by increasing O2 saturation (97.6% vs. 96.1%; p = 0.042) and tended to decrease end-tidal CO2 (32 mmHg vs. 35 mmHg; p = 0.08). While other slow breathing patterns demonstrated similar effects, only Ujjayi improved RSA while increasing heart rate and improving ventilatory efficiency. Conclusions: Hence, slow breathing per se can result in important cardiorespiratory changes, but the yogic breathing practice of Ujjayi, with glottic throat resistance, may hold the greatest promise for improving cardiorespiratory control in individuals with SCI (CTR ID No. NCT05480618).
RESUMO
Antecedentes: La enfermedad pulmonar obstructiva crónica (EPOC) produce una obstrucción al flujo de aire de los pulmones que genera tos, mucosidad y dificultad respiratoria. Presenta una alta morbimortalidad y tiene una prevalencia del 10,3% en todo el mundo. Recientemente se ha sugerido el uso del entrenamiento diafragmático en estos pacientes. Objetivo: El objetivo fue examinar la evidencia disponible sobre la eficacia del entrenamiento del diafragma sobre el FEV1, la prueba de la marcha de 6 minutos, la saturación de oxígeno, el tiempo inspiratorio, el tiempo espiratorio y la escala de supervivencia de la EPOC (BODE). Material y métodos: Se realizó una revisión sistemática siguiendo la declaración PRISMA. Resultados: Los resultados mostraron que el entrenamiento del diafragma es efectivo en pacientes con EPOC para mejorar el FEV1. Conclusiones: La prueba de la marcha de 6 minutos y la saturación de oxígeno; sin embargo, no es efectivo para las variables tiempo inspiratorio, tiempo espiratorio y escala de supervivencia de la EPOC (BODE).

Background: Chronic obstructive pulmonary disease (COPD) causes an obstruction to the airflow of the lungs, causing coughing, mucus, and difficulty breathing. It has a high morbidity and mortality with a prevalence of 10.3% worldwide. The use of diaphragmatic training in these patients has recently been suggested. Objective: The objective was to examine the available evidence on the effectiveness of diaphragm training on FEV1, 6-minute walk test, oxygen saturation, inspiratory time, expiratory time and COPD survival scale (BODE). Material and methods: A systematic review was carried out following the PRISMA regulations. Results: The results showed that diaphragm training is effective in patients with chronic obstructive pulmonary disease to improve FEV1. Conclusion: 6-minute walk test and oxygen saturation; however, it is not effective for the variables inspiratory time, expiratory time and the COPD survival scale (BODE). (AU)
