18 Clinical Trials for Various Conditions
To evaluate the extent to which a 12-week respiratory rehabilitation program consisting of inspiratory and expiratory breathing exercises compared to expiratory breathing exercises alone will help to improve shortness of breath, respiratory symptoms, breathing function, distance walked, and quality of life in those who are experiencing persistent shortness of breath after having had COVID-19. Measurements will take place at the beginning, 6 weeks, and at 12 weeks in the study.
It is well known that patients with spinal muscular atrophy (SMA) have progressive decline of respiratory muscle function. Therapy traditionally involved supportive means to ensure optimal nutrition and airway clearance. Nusinersen (spinraza) is a disease-modifying medication approved for treatment of SMA in pediatric and adult patients. The goal of this study is to observe pulmonary function test (PFT) changes and respiratory muscle strength trends throughout the first year of treatment. A prospective, longitudinal study measuring pulmonary function testing (PFTs) changes in spinal muscular atrophy (SMA) patients. Patients will be patients with SMA who are approved and maintained on nusinersen. Patient will have a baseline PFT. Investigators will repeat PFT at 3, 6, and 12 months while on nusinersen treatment.
Presbyphonia is an age-related voice disorder that affects more than 10 million people in the United States. Presbyphonia is characterized by vocal fold atrophy that impairs older individuals' ability to communicate, leading to social isolation and reduced quality of life. Outcomes from current treatment approaches are often suboptimal for patients with presbyphonia as they do not sufficiently challenge the respiratory system to induce meaningful change. It is highly likely that the addition of respiratory training would result in greatly improved outcomes, such as the ability to speak loud and long enough to have a normal conversation. The purpose of this study will be to examine the effect of adding inspiratory muscle strength training (IMST) or expiratory muscle strength training (EMST) to standard of care voice therapy on respiratory and voice outcomes in patients with an age-related voice disorder. Forty-eight participants diagnosed with presbyphonia will be blocked-randomized into three intervention groups, using a 3-parallel arm design: IMST and voice exercises, EMST and voice exercises, and voice exercises during all session. Study endpoints will be the change in voice and respiratory measures after four treatment sessions compared to baseline values. Response to treatment will be analyzed to determine if there are subgroups of high- or low-responders based on baseline voice and respiratory characteristics.
Study 701-201 is a study in patients with late-onset Pompe disease (LOPD). The study will test respiratory muscle strength initially and again after 24 weeks in subjects treated or not treated with BMN 701 .
The purpose of the study is to determine if respiratory muscle strength training will be beneficial for inspiratory and expiratory muscle strength in adults and children with Pompe disease.
The purpose of this study is to determine if inspiratory muscle strength training (IMST) will impact maximal inspiratory pressure and pulmonary function in patients with neuromuscular disease.
Respiratory muscle strength training (RMST) is a potential treatment option that has been shown to increase strength and ventilatory function in critically ill patients, patients on ventilators and patients with mild neuromuscular weakness. Currently researchers are examining the role of inspiratory muscle strength training (IMST) in pressure performance of ventilator dependent children with Pompe disease. However, normal pressure-flow-timing responses of lung function are not well-characterized in healthy children. The purpose of this study is to measure RMST-induced changes in respiratory function in healthy children. Children will undergo one session of lung function and strength testing. By studying healthy children's respiratory function, this study will also help to develop more efficient respiratory muscle training exercise prescriptions for children with neuromuscular weakness and impaired respiratory function.
This study has two parts: an observational part and an interventional part. The goal of the observational part of the study is to look for variations in swallowing in adults with obstructive sleep apnea (OSA) and in adults who don't snore. The main questions it aims to answer are: * Are there differences in swallowing between people with OSA and people who don't snore? * Are there differences in swallowing between people with OSA who do well with continuous positive airway pressure (CPAP) therapy and those who struggle with CPAP? This may help us better understand what causes OSA, which may help us develop alternate ways to treat or even prevent OSA. It may also help us improve care for people with OSA who struggle with CPAP. Participants will be aged 40-60 years, except women up to the age of 70 will be included in the healthy control (non-snorer) group. Participants will: * Undergo a type of x-ray study called a modified barium swallow study (MBS) * Come to MetroHealth Medical Center for a measurement visit to: * assess the strength of their tongue, lips, and cheeks * assess the strength of their breathing muscles * assess for restrictions in tongue mobility (tongue ties) * observe their resting breathing * take photos of their mouth and posture * take videos of them drinking and eating * Complete some questionnaires * For successful CPAP users: we will download data from the chip in their CPAP device * Do a home sleep test (except for successful CPAP users who have had a recent in-lab sleep test) The goal of the interventional part of the study is to test swallowing exercises in people ages 40-60 years with OSA who struggle with CPAP. The main question it aims to answer is: • Can swallowing exercises help people who struggle with CPAP sleep better with CPAP? Participants will: * Try to use CPAP for 2 weeks with individualized support * Do all the investigations listed in the observational part of the study * Do one or two courses of swallowing exercises, each of which would last 7 weeks. Participants will be asked to do daily exercises; exercises will take 20-30 minutes to perform. * Try to use CPAP for 2 weeks after the course of exercises * Repeat the investigations listed in the observational part of the study to see if changes occurred with the swallowing exercise intervention.
This research study is investigating whether completing breathing exercises before surgery helps heart transplant patients recover after surgery. Previous studies have shown that breathing exercises can improve breathing, cough, and swallow function in patients with other diseases/conditions. The current study will investigate the impact of a preoperative respiratory muscle strength training program on breathing and cough function, swallow function, patient-reported eating and swallowing fatigue, and health outcomes in individuals undergoing heart transplantation. Participants will: * undergo tests of breathing, cough, and swallow function * complete questionnaires about the treatment, their swallow function * complete breathing exercises daily
The primary purpose of this study is to determine the effect of administration of the oral beta-2 adrenergic agonist, albuterol, on respiratory muscle strength in individuals with cervical (neck) and high thoracic (upper back) spinal cord injury and to compare findings with those obtained in a demographically matched group that will receive placebo. Participation in this study will involve 12 weeks of pharmacological intervention during which participants will be randomized to receive either oral albuterol 4mg twice daily or placebo. All investigators and study participants will be blinded to randomization by our research pharmacy. Participation in the study will require study subjects to come to our lab for the total of 2 visits (at baseline and after week 12), during which a series of tests will be performed to assess their respiratory muscle strength and pulmonary function.
The purpose of this study is to examine the effectiveness of high intensity respiratory muscle strength training in treating blunted facial expression in people with Parkinson disease.
Spinal cord injury (SCI), especially involving the cervical and upper thoracic segments, can significantly compromise respiratory muscle function. Respiratory complications can ensue, including lung collapse and pneumonia, which are the primary cause for mortality in association with traumatic SCI both during the acute and chronic phases post-injury. Lesions at the level of the cervical or high thoracic spinal cord result in respiratory muscle weakness, which is associated with ineffective cough, mucus retention, and mucus plugging. Despite the fact that pulmonary complications are a major cause of morbidity and mortality in this population, there is a paucity of effective interventions in the SCI population known to improve respiratory muscle strength with pharmacologic interventions receiving little to no attention. The current objective of this study is to determine the effectiveness of 16 weeks of sustained release oral Albuterol to; (1) improve respiratory muscular strength, and (2) improve cough effectiveness.
Respiratory failure following extubation causes significant morbidity and increases mortality in teh surgical intensive care unit (SICU). However the causes of respiratory failure following extubation remain poorly understood. The investigators hypothesize that extubation failure can be predicted based on preoperative risk factors as well as ICU acquired morbidities including muscle weakness and renal failure.
A growing body of knowledge has documented that the diaphragm, the primary muscle of breathing, atrophies and weakens within days of instituting mechanical ventilation support. Diaphragm weakness has been implicated as a major contributor to difficulty with weaning, or breathing without ventilator support. This study will test whether instituting a diaphragm strength training rehabilitation program will reduce the time patients require mechanical ventilation in a surgical intensive care setting.
The investigators hypothesize that by applying a validated algorithm to accomplish early mobilization in surgical intensive care unit (ICU) patients, these patients will achieve a higher level of mobility which translates to shorter ICU length of stay and improved functional status at discharge. Additionally, the investigators hypothesize that genetic polymorphisms related to muscle strength and sleep will also explain some variance in these outcome variables.
The purpose of this study is to determine if inspiratory muscle strength training will increase the proportion of ventilator dependent patients weaned versus Sham treated patients.
The purpose of this research study is to determine if muscle training will improve snoring and obstructive sleep apnea. Subjects will receive a sleep study to determine the severity of their apnea. After this study, subjects will be randomly assigned to one of two groups. The first group will receiving a breathing trainer that may strengthen the muscles used to breath in and out. The second group will be receive a sham trainer which looks like the "real" trainer but is not able to produce a strengthening effect. Both groups will complete eight weeks of home based (real or sham) training. The sleep study will be repeated and we well measure any changes in measures of severity for obstructive sleep apnea.
Investigators will assess the effect of exercise on markers of inflammation and protein catabolism. This research study will further our understanding of how treating Chronic Critical illness (CCI) - related respiratory muscle weakness with strength training can not only improve muscle function, but also potentially blunt the inflammation and catabolism of Peristent Inflammation/Immunosuppression and Catabolism (PICS).
