A recent report (Morera Maiquez et al 2020) described reduced tic severity in people with Tourette syndrome during 1-minute epochs of median nerve stimulation (MNS) at 10 Hz. Among the various questions still to be answered is the question of whether a device to administer MNS is practical for use in a chronic, real-world setting. This study will recruit participants who complete the clinic-based, blinded, randomized controlled trial, https://clinicaltrials.gov/ct2/show/NCT04731714, to determine the real-world usage and apparent utility of median nerve stimulation in people with chronic tics.
