These devices promise to help you regulate your nervous system. As a therapist, I wanted to know if any of them actually deliver — and what they miss that a clinician would never miss.
This week on Therapy Tech Tuesday, I run a clinical audit of three of the most talked-about nervous
system wearables: the Muse EEG headband, Apollo Neuro, and HeartMath Inner Balance. I'm not
reviewing these as a tech blogger. I'm evaluating them against three biological criteria for
genuine autonomic regulation.
WHAT'S COVERED IN THIS EPISODE
✦ The three biological criteria every regulation device has to answer
✦ Muse (EEG neurofeedback): what the research shows, the suppression trap, and who it fits
✦ Apollo Neuro (vibrotactile stimulation): the passive regulation question and the agency problem
✦ HeartMath Inner Balance (HRV coherence): the strongest evidence base and why active engagement matters
✦ The contraindication gap — what none of these products address that a clinical advisor would
✦ A practical decision framework: who benefits, who to watch, and when to skip devices entirely
