The Impact of Autonomic Nervous System Modulation on Heart Rate Variability and Musculoskeletal Manifestations in Chronic Neck Pain: A Double-Blind Randomized Clinical Trial.

The role of autonomic nervous system (ANS) modulation in chronic neck pain remains elusive. Transcutaneous vagus nerve stimulation (t-VNS) provides a novel, non-invasive means of potentially mitigating chronic neck pain. This study aimed to assess the effects of ANS modulation on heart rate variability (HRV), pain perception, and neck disability.

The current study aimed to propose a method to directly measure right cervical vagal nerve activity (cVNA) alongside renal sympathetic nerve activity (RSNA) in conscious rats. The right cervical vagus nerve was surgically exposed and fitted with a bipolar electrode to record cVNA. A microcatheter was used to administer levobupivacaine to selectively block afferent cVNA.

Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia. Given the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) and its ability to promote brain plasticity, taVNS has emerged as a promising therapeutic option for SAH patients. However, the effects of taVNS on cardiovascular dynamics in critically ill patients, like those with SAH, have not yet been investigated.

Transcutaneous vagus nerve stimulation (tVNS) offers a non-invasive method to enhance noradrenergic neurotransmission in the human brain, thereby increasing cognitive control. Here, we investigate if changes in cognitive control induced by tVNS are mediated through locus coeruleus-induced modifications of neural activity in the anterior cingulate cortex. Young healthy participants engaged in a simple cognitive control task focusing on response inhibition and a more complex task that involved both response inhibition and working memory, inside a magnetic resonance imaging scanner.

Lennox-Gastaut syndrome (LGS) is a severe developmental and epileptic encephalopathy characterized by multiple drug-resistant seizure types, cognitive impairment, and distinctive electroencephalographic patterns. Neuromodulation techniques, including vagus nerve stimulation (VNS), deep brain stimulation (DBS), and responsive neurostimulation (RNS), have emerged as important treatment options for patients with LGS who do not respond adequately to antiseizure medications. This review, developed with input from the Pediatric Epilepsy Research Consortium (PERC) LGS Special Interest Group, provides practical guidance for clinicians on the use of these neuromodulation approaches in patients with LGS.
