Red Light Therapy for Feet & Ankles
The feet and ankles are treated for plantar fasciitis, ankle sprains, Achilles tendinopathy, diabetic neuropathy, and diabetic foot ulcers. The thick plantar skin requires NIR wavelengths for penetration, while the dorsal foot and ankle structures are relatively superficial.
Conditions Treated
Recommended Wavelengths
Recommended Device Types
- *Torch/pen devices
- *Small panels
- *Therapy pads
- *Wrap devices
Treatment Tips
- *For plantar fasciitis, target the calcaneal insertion from the sole
- *For Achilles tendinopathy, treat the tendon directly from posterior
- *NIR wavelengths needed for plantar treatments (thick skin)
- *For diabetic neuropathy, treat the entire plantar surface
- *Wrap devices work well for ankle treatments
- *For diabetic ulcers, always coordinate with medical team
Light Penetration Notes
The plantar skin is the thickest in the body (up to 4mm), requiring NIR wavelengths for adequate penetration to the plantar fascia. Dorsal foot and ankle structures are superficial and respond well to both red and NIR light. Achilles tendon is easily accessible to NIR treatment.
