Study: NCT06294509

Intervention type: DEVICE
Group type: ACTIVE_COMPARATOR
Intervention: in-house developed transcutaneous auricular Vagus Nerve Stimulation device
Description: taVNS in this study involves short electric pulses (0.25 ms) delivered to the ear's skin to activate the auricular branch of the Vagus. The pulses are current-controlled to ensure stability and delivered in a bipolar fashion to prevent skin irritation. Before each session, taVNS is calibrated for each participant. Starting at 0.1 mA, the intensity is increased stepwise until a comfortable maximum (typically 1.5-2.5 mA) is reached. Stimuli are delivered in short trains lasting 0.5 seconds each, with 13 pulses (0.25ms each) per train. Participants receive a maximum of 150 stimuli per session, totaling a maximum of 75 seconds of cumulative stimulation. Participants adapt their movements over up to six sessions across two weeks. The robotic task facilitates accurate movement tracking and provides interactive real-time feedback.
