Grounding techniques in DPDR primarily modulate the autonomic nervous system through sensory stimulation, activating the parasympathetic response and reducing hyperarousal in the limbic and prefrontal cortex. By engaging multiple sensory pathways simultaneously, these techniques help disrupt dissociative neural circuits, promoting re-engagement with present-moment physical sensations and attenuating the neurological disconnection characteristic of DPDR. The techniques essentially serve as a non-pharmacological intervention that neurologically reorients perception by stimulating somatosensory and proprioceptive processing.
