Peripheral Neuropathy

Published: Last updated:

Source: Clinical Research

Protocol for peripheral neuropathy, particularly diabetic neuropathy, using NIR wavelengths to improve nerve function and reduce neuropathic pain in the extremities. Treatment targets the affected nerves along their anatomical pathways.

Protocol Parameters

ConditionPeripheral Neuropathy
Wavelengths810nm, 830nm, 850nm
Dosage4-8 J/cm²
Irradiance50-100 mW/cm²
Duration10-15 minutes per area
Frequency3x per week for 8-12 weeks
Body Zonefeet
Evidence LevelModerate

Mechanism of Action

NIR light improves mitochondrial function in damaged peripheral nerves, enhances nerve conduction velocity, promotes Schwann cell proliferation for remyelination, and reduces neuroinflammation. It also improves local microcirculation, critical for nutrient delivery to compromised nerves.

Key Studies

  • Yamany & Sayed (2012) - PBM for diabetic neuropathy
  • Swislocki et al. (2010) - Phototherapy for painful diabetic neuropathy
  • Bashiri (2017) - PBM for peripheral neuropathy review

Treatment Tips

  • *Treat along the nerve pathway, not just the symptomatic area
  • *Include the plantar surface of the foot for foot neuropathy
  • *Good glycemic control essential for diabetic neuropathy
  • *Expect gradual improvement over 8-12 weeks

Contraindications

  • !Active foot ulcers (address separately)
  • !Severe peripheral vascular disease
