Laser therapy
Cold laser therapy, also known as low-level laser therapy (LLLT), is a non-invasive treatment used in podiatry to reduce pain, inflammation, and promote tissue healing in the foot and lower limb. Unlike surgical or high-power lasers, cold laser does not generate heat and is painless, making it safe for a wide range of patients.
How it works
Cold laser delivers specific wavelengths of light to targeted tissues, which are absorbed by cells to stimulate cellular metabolism. This can:
- Increase ATP production, providing energy for tissue repair
- Enhance collagen synthesis, supporting tendon, ligament and skin healing
- Reduce inflammatory mediators, helping to decrease pain and swelling
- Improve local circulation, delivering oxygen and nutrients to injured areas
Evidence base
Research indicates that cold laser therapy can be effective in managing plantar fasciopathy, Achilles tendinopathy, wound healing, and chronic inflammatory foot conditions. Studies show reductions in pain and improvements in function when LLLT is used alongside standard podiatry care, such as stretching, strengthening, orthotics, and footwear management. Its benefits appear greatest when applied as part of a multi-modal treatment plan.
Safety and considerations
Cold laser therapy is generally safe and well tolerated. It is not recommended for:
- Areas with active malignancy or local tumours
- Over the eyes
- In patients who are pregnant
In podiatry, cold laser therapy is often combined with other evidence-based interventions to accelerate healing, reduce pain, and restore normal function in chronic or acute foot and lower limb conditions.
