The Navigated Brain Therapy (NBT®) System is a device that uses navigated transcranial magnetic stimulation (nTMS) for use in stroke rehabilitation.

Navigation is achieved by visualizing the electric field (e-field) generated by the TMS coil in a 3D image rendered from the patient’s MRI scan. Stimulation intensity is calculated from the accurate measurement of brain excitability and the personal resting motor threshold (MT) of each patient. The proven accuracy confirms optimal treatment location for the individual patient, and ensures that stimulation treatment is always repeated at the same location, every time and for every session.


The Navigated Brain Therapy System is CE-marked for patients recovering from stroke as a supplement to conventional rehabilitation.

Nexstim’s noninvasive Navigated Brain Therapy (NBT) System is not approved for Stroke Therapy by the Food and Drug Administration in commercial distribution or use in the United States and is available to select physician for investigational use only.
