Using Mobile Devices for Neurofeedback to Reduce Opioid Use in Chronic Pain

Neurofeedback intervention delivered via mobile app. Participants wear an EEG headset which is connected to a mobile app that delivers feedback about brainwave data indicating whether they are in a calm, relaxed state. Participants hear a lower/simple sound when they are below a target level and higher/richer sound when they approach or achieve their target.
