Pulsed 830‐nm Laser Irradiation Modulates Aδ‐ and C‐Fiber–Mediated Pain Thresholds in Healthy Adults: A Randomized, Sham‐Controlled Trial

Key Points

• This research aims to determine the effect of pulsed 830-nm laser irradiation on pain thresholds mediated by Aδ and C-fibers in healthy individuals.
• Conducted a randomized, sham-controlled trial.
• Involved healthy adults as participants.
• Applied pulsed 830-nm laser irradiation and compared effects with a sham treatment.
• Assessed pain thresholds through standardized testing.
• Laser irradiation significantly modulated pain thresholds compared to sham treatment.
• Observed alterations in pain sensitivity related to Aδ and C-fiber activity.
