Filter by:Autonomic modulation by transcutaneous vagal nerve stimulation in acute ischaemic stroke requiring mechanical thrombectomy: a phase IIa, sham controlled randomised trial.
By measuring specific electrical parameters at acupuncture points that have been shown to correlate with ANS activity, the objectives of this study were to: 1) determine if CV4 has any influence on the bioelectric properties of the acupuncture meridian system, and 2) determine if CV4 affects the ANS.
This study looks to characterize autonomic nervous system dysfunction after spinal cord injury and identify the potential role that transcutaneous spinal cord stimulation may play at altering neuroregulation. The autonomic nervous system plays key parts in regulation of blood pressure, skin blood flow, and bladder health- all issues that individuals with spinal cord injury typically encounter complications. For both individuals with spinal cord injury and uninjured controls, experiments will utilize multiple parallel recordings to identify how the autonomic nervous system is able to inhibit and activate sympathetic signals. The investigators anticipate that those with autonomic dysfunction after spinal cord injury will exhibit abnormalities in these precise metrics. In both study populations, transcutaneous spinal cord stimulation will be added, testing previously advocated parameters to alter autonomic neuroregulation. In accomplishing this, the investigators hope to give important insights to how the autonomic nervous system works after spinal cord injury and if it's function can be improved utilizing neuromodulation.
In this randomized double-blind trial, we investigated whether externally induced left-hemispheric frontoparietal theta synchronization by multi-electrode online theta (6Hz) transcranial alternating current stimulation (tACS) would enhance the influence of a working memory training on negative symptoms of schizophrenia.
The function of the autonomic nervous system can be assessed using baroreflex sensitivity (BRS) and heart rate variability (HRV). Decreased HRV has been shown to be predictive of morbidity and mortality in diverse medical conditions such as acute myocardial infarction, aneurysmal subarachnoid haemorrhage, autoimmune diseases, sepsis and surgery. The function of the autonomic nervous system has not yet been investigated in a "pure hypovolemia" model. The aim of the current study is therefore to investigate and describe the function of the autonomic nervous system prior to, during and after reduction of blood volume in healthy blood donors.
The aim of this study it's to analyze the relationship between autonomic nervous system balance (ANSb) and chronic pain conditions, especially in this case, non-especific chronic low back pain (CLBP). Most of physiotherapy approaches focus only in biomechanical aspects, leaving aside what kind of factors could perpetuate CLBP. Since 1985, ANSb was studied due to its potential contribution to chronic pain. Electrical stimulation, through interferential currents (IFC), it's a safe and well-known therapy used in CLBP with good outcomes regarding pain relief. The main objective of this study it's to quantify the association between CLBP and ANSb alterations. In second place, the research team aims to record the influence of IFC over pain and ANSb in those subjects.
The present study investigates the efficacy of a brief and cost-effective video-intervention that combines bottom-up elements of deep breathing and third-wave cognitive behavioral therapy techniques (i.e., mindfulness and compassion) on coping strategies during the COVID-19 pandemic.
The study aimed to investigate the effects of high-definition transcranial random noise stimulation over bilateral prefrontal cortex on psychopathological symptoms, other clinical outcomes, autonomic functioning ,and brain oscillatory activity in schizophrenia patients.
Some studies have compared the clinical profile during propofol induction anesthesia with Target-controlled infusion (TCI) and manually bolus showed similar control of anesthesia, such as depth of anaesthesia and hemodynamic stability, but did not use an objective measure of instantaneous autonomic activity during the brief time of induction anesthesia. In this study, TCI and manually bolus of propofol injection techniques during induction were studied with wavelet-based spectral analysis and the amplitudes of the pulse plethysmographic. The investigators hypothesized that during propofol induction anesthesia, the instantaneous ANS activities was more stable with TCI than traditional manually bolus
The study aimed to investigate the effects of bimodal anodal transcranial direct current stimulation (tDCS) over bilateral dorsolateral prefrontal cortex (DLPFC) on psychopathological symptoms, insight, psychosocial functioning, neurocognitive function and heart rate variability (HRV) in schizophrenia patients
