Filter by:The aim of this study is to evaluate in a clinical trial a rehabilitation device for patients with obstructive sleep apnoea (OSA) based on oropharyngeal electrical stimulation, which strengthens the dilating muscles of the upper airway, improves mechanical laryngopharyngeal sensitivity and improves OSA. Furthermore, to perform experimental electrotherapy, nasoendoscopy, polygraphy and polysomnography tests with the device in order to calculate thresholds of functional and sensory intensities on the dilating muscles of the upper airway in patients with OSA. These tests also include the detection of signals that measure breathing events during sleep in patients with OSA in order to use them in the control mechanisms of the electrostimulation device. Assess the effects and safety of the device in a group of five healthy volunteers for preliminary results. Finally, to evaluate in a small group of patients with OSA the device capacity to stimulate the upper-airway dilating muscles and to reduce the Apnea-Hypopnea Index (AHI) and oxygen desaturation indices when the electrostimulation device is used over a medium-term period (eight weeks) with morning and evening therapy sessions.
The primary objective of this randomized clinical trial is to evaluate the role of patient researchers in promoting the resumption of CPAP therapy in apneic patients who had previously stopped CPAP
The aim is to compare a programme of controlled exercises therapy vs a programme of non controlled exercises therapy in patients with sleep apnea
This study is looking at the way in which patients with obstructive sleep apnoea (OSA) are diagnosed. The investigators current practice is to offer patients who are referred to the sleep centre with possible sleep apnoea a single night's oximetry recording. A decision is then made based on this screening test as to whether the patient has OSA, does not have OSA or requires a further investigation. There can be significant variation in the severity of OSA between nights. This study is designed to investigate if recording data from multiple nights will give any better indication on the presence and severity of obstructive sleep apnoea. Patients referred for overnight oximetry recordings that report excessive daytime sleepiness are eligible to enter the trial. On enrolment participants will all undergo a single night recording with the oximetry device currently in use by the recruiting sleep centre. In addition they will be asked to wear the prolonged recording oximeter (PRO) that allows for multiple nights data to be stored, and continue wearing this for a total of four nights. On returning both oximetry devices, this data will then be analysed and if it demonstrates evidence of OSA participants will return to the standard clinical pathway and be offered a trial of treatment with continuous positive airway pressure (CPAP) therapy. If no evidence of OSA is seen participants will also revert back to the standard clinical pathway, which may involve a further inpatient sleep investigation being arranged. The number of patients identified as having OSA based on the single first night recording will be compared to those identified as having OSA only after the additional nights recording. All participants will return to the current standard pathway of care on leaving the trial.
Insomnia and OSA coexist in clinical populations, but the prevalence of comorbid insomnia among OSA patients in the community and risk factors remain poorly known. Little is known about the impact of sleep apnea and insomnia on the quality of life and quality of sleep compared to the presence of one of the sleep disorders alone. Our hypothesis is that the co-existence of OSA and insomnia is high in our community. We also hypothesized that the co-existence of OSA and insomnia promotes greater impairment of quality of life and quality of sleep when compared to the presence of OSA or insomnia alone. Patients referred to polysomnography will be submitted to 6 questionnaires to assess daytime sleepiness (EPWORTH), insomnia severity index (ISI), anxiety and depression assessment (Beck's anxiety and depression inventory), quality of life assessment(WHOQOL- BREF) and sleep quality assessment (Pittsburgh questionnaire) and they will also be submitted to a polysomnography type III. It will be calculated the frequency of insomnia, OSA and the comorbidity between insomnia and OSA in the sample. It will be analysed correlations between the insomnia severity index, apnea and hypopnea index, Epworth sleepiness scale, quality of life scale (WHOQOL-BREF), anxiety and depression scale (Beck's anxiety and depression inventory) and Pittsburgh sleep quality scale. Insomnia severity index scores, Epworth sleepiness scale, quality of life scale (WHOQOL-BREF), anxiety and depression scale (Beck anxiety and depression inventory) and Pittsburgh sleep quality scale will be compared according to the presence and absence of OSA and the presence and absence of insomnia and the presence of the comorbidity insomnia and OSA.
The study is a thirty three week, prospective, open-label, randomized, parallel-group non-inferiority study. The study aims to investigate the Substantial Equivalence of a novel mandibular device called iSlpr™, produced by BioAnalytics, to a currently approved device, SomnoDent® Classic, in the treatment of mild to moderate Obstructive Sleep Apnoea (OSA) and snoring.
Adults with Down syndrome (DS) have a high prevalence of obstructive sleep apnea (OSA), which may worsen cognitive performance. In general population, continuous positive airway pressure (CPAP), the gold Standard treatment for OSA, partially reverses cognitive impairment secondary to OSA. CPAP treatment, however, is not regularly proposed in adults with DS and OSA. It is usually presumed both by caregivers and physicians, that DS patients will not tolerate or adapt to the treatment, and that they would not benefit much more from CPAP treatment. Therefore, data about the feasibility and impact of CPAP treatment on cognitive function in this population is lacking. The main objective of this study is to investigate cognitive performance in adults with DS and OSA, the corresponding functional brain changes and their reversibility with CPAP treatment.
The main objective of this study is to compare the change in the apnea-hypopnea index (AHI) in patients with mild to moderate sleep apnea without daytime sleepiness after 12 months of myofunctional therapy exercises with respect to the placebo group (the placebo group will be instructed in simulation exercises that do not alter the function or morphology of the upper airway)
The aim of this study is to investigate the effects of acupuncture press needle in mild to moderate obstructive sleep apnea patients.
Obstructive sleep apnea syndrome (OSAS) is defined as a total cessation of upper airway flow for at least 10 seconds. OSAS is considered under diagnosed and it is assessed by a full-night sleep polysomnography. Continuous positive airway pressure (CPAP) is considered the first line treatment to OSAS, however physical exercise has emerged as an adjunct and/or alternative strategy to CPAP in OSAS patients.
