Peripheral Neuropathy
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
| Condition | Peripheral Neuropathy |
| Wavelengths | 810nm, 830nm, 850nm |
| Dosage | 4-8 J/cm² |
| Irradiance | 50-100 mW/cm² |
| Duration | 10-15 minutes per area |
| Frequency | 3x per week for 8-12 weeks |
| Body Zone | feet |
| Evidence Level | Moderate |
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.

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
