What Is Low-Level Laser Therapy?
Low-level laser therapy (LLLT), also called photobiomodulation (PBM), uses specific wavelengths of light (typically 600–1000 nm) at low power levels to stimulate biological processes at the cellular level. Unlike surgical lasers that cut or ablate tissue, LLLT does not heat tissue — it stimulates cellular energy production (ATP synthesis) through cytochrome c oxidase in the mitochondria.
Evidence-Based Effects
Multiple systematic reviews support LLLT for: Reduced inflammation: Decreases pro-inflammatory cytokines (IL-6, TNF-alpha). Accelerated tissue repair: Stimulates fibroblast activity, collagen synthesis, and angiogenesis. Pain relief: Reduces central and peripheral sensitisation. Nerve regeneration: Promotes Schwann cell activity and axonal sprouting.
Conditions Treated
LLLT is effective for: Achilles tendinopathy, lateral epicondylalgia (tennis elbow), plantar fasciitis, carpal tunnel syndrome, osteoarthritis (knee and hand), neck pain, shoulder pain, and wound healing.
Treatment Parameters
The therapeutic window for LLLT is specific — too little or too much energy is ineffective. We use calibrated laser units with precise dose (J/cm²) delivery to ensure optimal therapeutic outcomes.
What to Expect
Treatment is painless — patients typically feel nothing during laser application. Sessions last 5–15 minutes per area. A course of 6–12 sessions is typically recommended for chronic conditions, with most patients noticing improvement after 3–4 sessions.
