Remote Electrical Stimulation as a Long-term Intervention for Endometriosis Flare Ups

The NettleEndo device is a portable, home-use transcranial direct current stimulation (tDCS) system designed to deliver low-intensity electrical stimulation to targeted brain regions. The device delivers a constant current of 2 mA in the active stimulation group, targeting the left primary motor cortex (M1) and left dorsolateral prefrontal cortex (DLPFC) through pre-set electrode positioning.

The sham version of the NettleEndo device is visually identical to the active device and is used under the same schedule. The device is pre-programmed to deliver a brief 2 mA current for 20 seconds at the beginning of each session to mimic the initial skin sensations of active stimulation, after which no current is delivered for the remainder of the session. This allows participants to remain blinded to their group assignment. The device is used with the same electrode positioning as the active version.
