The THERA PRAX® MOBILE is a biofeedback system supporting patients to learn to self regulate their brain activity (EEG biofeedback). It is intended to be used for EEG biofeedback with the slow cortical potentials (SCP) protocol in the treatment of children with attention deficit/ hyperactivity disorder (ADHD).
