Distinct activation thresholds of unmyelinated C-fiber afferents by dorsal root ganglion and peripheral nerve stimulation

Key Points

• C-fiber afferents exhibit efficient activation through dorsal root ganglion stimulation, impacting chronic pain treatment.
• The findings highlight a notable structural and molecular mechanism supporting the superior efficacy of DRG stimulation.
• Analysis of therapeutic techniques shows how DRG stimulation preferentially activates specific pain pathways, essential for pain management.
• The evidence suggests the need for further exploration of DRG interventions for better pain relief outcomes.
