Trial of Auricular Vagus Nerve Stimulation in Painful Covid Long

Patients infected with Covid 19 suffer from frequent pain (headache, migraines, joint pain, muscle pain) in the acute phase which may persist after a stay in intensive care or in an intensive care unit, in the event of post-traumatic stress syndrome, pre-existing comorbidities. The pain mechanisms observed during the covid epidemic are nociceptive / inflammatory pain, neuropathic pain, and nociplastic pain. Auricular transcutaneous vagus nerve stimulation (tVNS) is a promising therapeutic strategy that may reduce inflammation and pain level. Colosat is a prospective non-randomized pilot feasibility study. Colosat is a 8 weeks non randomized trial investigating the painful Covid long. tVNS will be performed using a transcutaneous lectrical nerve stimulation (TENS) device connected to an auricular electrode stimulating the cutaneous area of the left ear innervated by the auricular ascendant branch of the vagus nerve.
