Filter by:The use of vagus nerve stimulation (VSS), one of the examples of neuromodulation therapies, continues to increase in the medical field. Basically, invasive (iVSS) and transcutaneous VSS (tVSS) can be performed. tVSS is more preferred because of its advantages such as easy application, not requiring surgical procedure and having fewer side effects. VSS has long been an approved treatment modality in the treatment of epilepsy and refractory depression. tVSS can be administered from the auricular-auricular or posterior ear region. The vagus nerve (VS) belongs to the parasympathetic branch of the autonomic nervous system and has an effect on vital functions. There are also studies in the literature showing that VS stimulation reduces inflammation. In addition to this effect, the vagus nerve may also show analgesic activity through pain-related pathways. Due to its anti-inflammatory and analgesic effects, VSS has become a new treatment method in diseases in which various inflammatory processes are shown in the etiology such as inflammatory bowel diseases, musculoskeletal system diseases and central nervous system diseases.
Transcutaneous Auricular Vagus nerve stimulation may be successful in cardiac modulation because of the cardiac connections of the vagal nerve. Therefore, in order to observe the cardiac effects, it was analysed the changes in pulse rate, systolic and diastolic blood pressure after transcutaneous auricular vagus nerve stimulation application.
This between-subject, longitudinal pilot study in healthy college students aims to explore the acceptability and preliminary outcomes of two novel and complementary interventions that may improve stress and sleep: transcutaneous vagus nerve stimulation (tVNS) and a mobile mindfulness intervention.
Oromotor dysfunction and poor feeding is common after premature birth and hypoxic ischemic encephalopathy (HIE). Pairing vagus nerve stimulation (VNS) with motor activity accelerates functional improvements after stroke. This study is designed to investigate whether transcutaneous auricular VNS (taVNS) paired with oromotor rehabilitation is tolerable, safe, and facilitates motor learning in infants who have failed oral feeding.
The Vagus nerve (VN) serve as an "unconscious inner brain" that integrates messages from the body and provides metabolic homeostatic regulation to various organs.In this study the investigators want to compare different ways to stimulate the vagus nerve to assess their respective effects compared to a sham stimulation. Each participant will be exposed in a random way to 7 different ways to stimulate the VN: - Manual Head Massage - Mechanical Head Massager (BREO Inc. Helmet) - Low laser Therapy (LLT) - Sham LLT - Transcutaneous Electrical Nervous Stimulation (TENS) ear stimulation (as testing phase prototype device) - Deep and slow breathing (as testing intervention based on video app) - Relaxed reading time (as control situation) Therefore, within the same design the investigators want to conduct two separate studies that should lead to two separate publications: - Study 1: comparison of manual head massage to mechanical Helmet massager and relaxed reading - Study 2: comparison of LLT with sham LLT and relaxed reading The two other interventions: TENS ear stimulation and Deep and Slow breathing are purely observational to gain knowledge in context of a convenient design.
Two important mechanisms play a major role in the pathogenesis of type 2 diabetes: insulin resistance of the target tissues and the impaired insulin secretion from pancreatic β-cells. Postprandial factors (such as insulin) are perceived by the human brain and induce signals that regulate glucose metabolism via the parasympathetic nervous system. Deep breathing exercise can increase parasympathetic nerve activity. Heart rate variability (HRV) in healthy people can be significantly increased by deep breathing maneuvers, indicating a shift from sympathetic activity to parasympathetic activity. The hypothesis is that this postprandial shift results in a change in peripheral glucose metabolism. In turn, the increased parasympathetic activity could potentially result in a change in postprandial insulin sensitivity or secretion. To test this hypothesis, this study investigates the effect of deep breathing exercise versus normal breathing on insulin sensitivity, on insulin secretion, glucose tolerance, resting energy expenditure, and on parasympathetic tone (analysis of heart rate variability).
