Box Breathing and Physiological Feedback Before Endoscopy

This study aims to evaluate the effects of box breathing exercises and real-time physiological feedback-administered alongside standard nursing care prior to endoscopy-on patients' stress levels, comfort levels, and vital signs. Endoscopy procedures can induce pre-procedural stress and anxiety in patients, potentially affecting their comfort and physiological status. The study will be conducted as a two-group randomized controlled trial. Participants will be randomly assigned to either the study group or the control group. In addition to standard nursing care, the study group will receive guided box breathing exercises and real-time physiological feedback before the endoscopy. The control group will receive only standard nursing care. The study will assess the impact of the intervention on patients' stress levels, comfort levels, and vital signs. It is hypothesized that box breathing exercises and real-time physiological feedback will reduce stress levels, enhance patient comfort, and positively influence vital signs. The findings are expected to contribute to the development of non-pharmacological nursing interventions for managing patient stress and comfort during the pre-endoscopy period.

Three Breathing Techniques for Heart Rate Variability, Attention, Reaction Time, and Anxiety

This randomized controlled trial compared the effects of Mindfulness Breathing, Box Breathing, and Nadi Shodhana Pranayama on heart rate variability, attention performance, reaction time, and anxiety in healthy adults aged 18-40 years. Participants were randomly assigned to one of three breathing intervention groups and practiced their assigned technique daily for six weeks. Primary outcomes included resting heart rate, RMSSD, and respiratory rate derived from 5-minute heart rate variability recordings. Secondary outcomes included attention performance assessed by the Digit Cancellation Test, reaction time assessed using the BlazePod system, and state and trait anxiety assessed using the State-Trait Anxiety Inventory. Participants received standardized face-to-face instruction, home practice videos, and daily WhatsApp reminders throughout the intervention.

Breathing Exercises on Lung Function

aim of this study is to evaluate the efficacy of pulmonary rehabilitation program as a non-pharmacological treatment method to: Improve functional capacity as assessed by six-minute walking distance (6MWD) test. Improve dyspnea level as assessed by Medical Research Council (MRC) dyspnea scale. Improve pulmonary function tests and arterial blood gas.

Breathing Exercises for Dyspnea and Anxiety in Heart Failure

Heart failure is a leading cause of emergency department admissions, with dyspnea and psychological distress being among the most common presenting symptoms. This randomized controlled trial aims to evaluate the effect of nurse-guided diaphragmatic breathing and pursed-lip breathing exercises on dyspnea and psychological distress in patients presenting to the emergency department with heart failure. A total of 112 eligible participants will be randomly assigned in a 1:1 ratio to either an intervention group receiving breathing exercises in addition to standard care or a control group receiving standard care alone. Dyspnea severity will be assessed using the Modified Borg Dyspnea Scale, and psychological distress will be assessed using the Distress Thermometer at predefined time points. The findings are expected to provide evidence for the effectiveness of a simple, low-cost, nurse-led non-pharmacological intervention in improving symptom management in patients with heart failure.

Teach-Back-Based Incentive Spirometry Training

Patients undergoing cardiac surgery may experience difficulty performing breathing exercises after surgery, which can increase the risk of respiratory complications. Incentive spirometry is a breathing exercise technique commonly used to support lung function; however, patients may not always perform this exercise correctly or frequently enough. This study aims to evaluate the effect of a structured incentive spirometry education program based on the teach-back method on patients' ability to perform the exercise correctly and their frequency of use after cardiac surgery. This randomized controlled study will include 60 patients admitted for elective cardiac surgery at a university hospital in Türkiye. Participants will be randomly assigned to either a routine care group or an intervention group. Patients in the intervention group will receive structured incentive spirometry education using the teach-back method in addition to routine care, while the control group will receive routine care only. The ability to perform incentive spirometry correctly and the frequency of exercise use will be evaluated. The findings of this study may provide information about effective education strategies to improve postoperative breathing exercise practices in cardiac surgery patients.

Feasibility of Breathwork Intervention With Older Adults After Knee Surgery

Postoperative complications after surgical procedures, including following total knee arthroplasty (TKA), have a negative impact on the health and well-being of surgical patients. Older adults (≥65 years) are particularly vulnerable to postoperative complications and their associated morbidities due to the biological aging process. Older adults comprise nearly half of surgical patients worldwide, and this number is expected to increase in the next 10-20 years as the aging population continues to grow. TKA is the most common procedure undergone by older adults, and the rate of TKA procedures is also expected to rise. Despite perioperative guidelines and protocols to prevent postoperative complications, the prevalence of postoperative complications following TKA is approximately 12%. Given these statistics, millions of older adults undergoing TKA may be at risk for postoperative complications and their associated morbidities in the coming decades. Therefore, additional interventions are needed to combat postoperative complications in this population. The body's natural response to surgery, also known as the surgical stress response (SSR), contributes to postoperative complications through complex mechanisms involving the autonomic nervous system (ANS). Increased sympathetic nervous system (SNS) activity, or the body's fight-or-flight response, causes dysregulation in feedback systems that regulate the stress response, potentially leading to poorer outcomes. Interventions, such as breathwork, that induce the parasympathetic nervous system (PNS), or the body's rest-and-digest response, have been shown to balance the ANS, regulate stress biology, and improve outcomes. This study will examine the feasibility of adding a breathwork intervention (Box Breathing), compared to an attention control, to standard perioperative care for older adults undergoing TKA. This study will also examine the proof of concept that Box Breathing, compared to an attention control, may help regulate the SSR by assessing an objective measure of stress-related biology, diurnal cortisol rhythm, and gathering self-report information on pain, anxiety, depression, and quality of recovery following TKA.

Spinal Cord Stimulation and Respiration After Injury

Respiratory motor control deficit is the leading cause of morbidity and mortality in patients with spinal cord injury. The long-term goal of this NIH-funded study is to develop a rehabilitation strategy for respiration in patients with spinal cord injury as a standard of care. Respiratory function in patients with chronic spinal cord injury can be improved by using inspiratory-expiratory pressure threshold respiratory training protocol. However, the effectiveness of this intervention is limited by the levels of functional capacity preserved below the neurological level of injury. Preliminary data obtained for this study demonstrate that electrical spinal cord stimulation applied epidurally at the lumbar level in combination with respiratory training can activate and re-organize spinal motor networks for respiration. This study is designed to investigate respiratory motor control-related responses to epidural spinal cord stimulation alone and in combination with respiratory training. By characterization of respiratory muscle activation patterns using surface electromyography in association with pulmonary functional and respiration-related cardiovascular measures, the investigators expect to determine the specific stimulation parameters needed to increase spinal excitability below level of injury to enhance responses to the input from supraspinal centers that remain after injury and to promote the neural plasticity driven by the respiratory training. This hypothesis will be tested by pursuing two Specific Aims: 1) Evaluate the acute effects of epidural spinal cord stimulation on respiratory functional and motor control properties; and 2) Evaluate the effectiveness of epidural spinal cord stimulation combined with respiratory training.

Effect of Visual Feedback From the SpiroGym Mobile Application

The previous pilot study showed that two weeks of intensive expiratory muscle strength training (EMST) with SpiroGym was sufficient to significantly improve voluntary peak cough flow (PCF). The improvement was quantitatively comparable to that reported in other intensive EMST studies of longer duration. To explain this rapid improvement, we considered the potential contribution of SpiroGym's visual feedback. We assumed that real-time visual feedback increased training effort compared with conventional EMST performed without immediate feedback. The aim of this study is to evaluate the effect of visual feedback provided by the SpiroGym mobile application on performance during expiratory muscle strength training in patients with Parkinson's disease.

The Effects of Breathing Exercises and Music Intervention During Labor on Pain Perception, Birth Expectations, and Birth Satisfaction in Primiparous Women

This randomized controlled trial aimed to evaluate the effects of music listening and breathing exercises during labor on pain perception, birth expectations, and birth satisfaction among primiparous women. This randomized controlled trial was conducted in the delivery unit of a hospital located in the Inner Aegean Region of Turkey. The study included 90 primiparous pregnant women admitted for vaginal delivery. Participants without visual, auditory, or neurological impairments were included and randomly assigned into three groups: music intervention group, breathing exercise group, and control group (n=30 in each group). Participants were randomly assigned to one of three groups (Music Intervention, Breathing Exercise, Control) using a computer-generated randomization sequence. Allocation concealment was ensured by using sealed, opaque envelopes prepared by a researcher who was not involved in participant recruitment or assessment. In the music intervention group, participants were introduced to 12 music tracks at 36 weeks of gestation during childbirth preparation classes. Short samples of these tracks were played during the class, and the full tracks were then shared with participants via WhatsApp to encourage regular listening at home. During the prenatal period, participants received regular WhatsApp reminders every few days to listen to the music. During labor, participants were encouraged to listen to music whenever they wished. Additionally, at 4 cm, 6 cm, and 8 cm cervical dilation, all participants in this group listened to their preferred tracks from the playlist for 20 minutes. Pain intensity was measured using the Visual Analog Scale (VAS) before and after each music session. In the breathing exercise group, Lamaze breathing techniques were taught during prenatal classes and practiced throughout the labor process. They were encouraged to practice these exercises throughout labor. At 4, 6, and 8 cm cervical dilation, guided breathing exercises were conducted, and pain was assessed using the Visual Analog Scale (VAS) before and after each exercise. In the control group, participants received routine maternity care. VAS pain assessments were conducted at the same cervical dilation points (4, 6, and 8 cm), without any additional interventions. For all participants, the durations of the first, second, and third stages of labor were recorded and compared across groups. In the postpartum period, the Birth Expectation Scale and Birth Satisfaction Scale were administered. Study data included sociodemographic information, VAS pain scores, and scores from the birth expectation and satisfaction scales.

The Effects of Breathing Exercises on Exam Anxiety, Attention Deficit, and Academic Achievement in Students Preparing for University Entrance Exams

This study investigates the effects of breathing exercises on exam anxiety, attention, and academic achievement in students preparing for university entrance exams. University entrance exams are significant milestones in students' educational and career paths, often causing high levels of stress and anxiety. These psychological pressures can negatively impact learning, focus, and overall academic performance. The study will involve students who volunteer to participate and meet the inclusion criteria. Participants will be guided through structured breathing exercises designed to reduce stress and enhance concentration. The program will be conducted over several sessions, during which students will practice specific breathing techniques under supervision. Primary outcomes of the study include the assessment of changes in exam anxiety levels, attention, and academic performance. Secondary outcomes may include students' self-reported stress management skills and overall well-being. Data will be collected using validated questionnaires, attention tests, and academic performance records. The purpose of this research is to determine whether regular practice of targeted breathing exercises can provide practical benefits for students, helping them manage anxiety, improve focus, and achieve better academic outcomes. Findings from this study may also offer guidance for educators, parents, and healthcare providers on effective, low-cost interventions to support students during high-pressure academic periods. Participants are encouraged to follow instructions carefully and attend all sessions to gain the full benefit of the intervention. Participation is voluntary, and students can withdraw at any time without any negative consequences. Confidentiality of all collected data will be strictly maintained. By contributing to this research, participants will help advance understanding of non-pharmacological methods to improve student mental health and academic performance, potentially shaping future educational and stress-management programs.
