Using the Cholinergic Anti-Inflammatory Pathway to Treat Systemic Lupus Musculoskeletal Pain

Patients will receive transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes daily for 4 consecutive days. The device is a handheld electrical pulse generator and a pair of electrodes to be placed at the ear for stimulation. The specific target at the ear will be the auricular branch of the vagus nerve which innervates the skin of the ear canal. Electrodes will be placed near/at the entrance to the canal of the ear to provide stimulation to the auricular branch.

Patients will receive sham transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes daily for 4 consecutive days. Sham stimulation will be performed in the identical manner as true transcutaneous stimulation except that the patient will not receive electrical stimulation of the vagus nerve.
