How they work
Biofeedback
Core mechanism: Real-time physiological feedback enables clients to learn voluntary regulation of autonomic nervous system responses, improving HRV, reducing sympathetic dominance, and building transferable self-regulation skills
Ontology: Psychological distress as partially constituted by autonomic dysregulation, accessible to direct intervention through feedback-based learning at the physiological level
EMDR
Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)
Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition

What each assumes — and misses
Biofeedback
Philosophical roots: Cybernetics (Wiener); behavioral learning theory; autonomic neuroscience; polyvagal theory (Porges); self-regulation theory
Blind spots: Equipment costs limit access; resonance frequency varies by individual and requires calibration; consumer wearables not equivalent to clinical biofeedback; effects may not generalize without explicit transfer training
Therapeutic voice: Watch your breathing rate match the curve on the screen. When they align, notice what happens in your body.
EMDR
Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing — pragmatic, not philosophically derived)
Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base
Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.
Choosing between them
Biofeedback (Somatic) and EMDR (Trauma-Focused) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
