Every claim we make is backed by peer-reviewed research. No hype. No exaggeration. Just published clinical evidence from leading universities and hospitals worldwide.
Red (660nm) and near-infrared (850nm) light is absorbed by Cytochrome C Oxidase, an enzyme inside your mitochondria. This triggers a chain of healing effects at the cellular level.
Light photons accelerate electron transport in mitochondria, increasing cellular ATP production to 170–190% of normal levels within 20 minutes. More energy means faster healing and repair.
Photons displace nitric oxide from mitochondrial enzymes, releasing it into surrounding tissue. This NO drives vasodilation, increasing blood flow and nutrient delivery to your knee joint.
PBM generates low-level reactive oxygen species that activate NF-κB, a master switch that calms inflamed tissue while promoting repair. Studies show significant decreases in TNF-α, IL-1β, and IL-6.
Light stimulates chondrocyte proliferation and activates TGF-β1 growth factors, promoting collagen synthesis. Studies show it prevents proteoglycan loss, preserving the cartilage cushion in your knee.
Each modality targets a different layer of knee joint pathology. Together, they address the whole joint, not just one symptom.
Operates at the cellular & molecular level. Photons penetrate tissue to boost mitochondrial energy, reduce inflammation, and stimulate cartilage repair.
Operates at the tissue & fluid level. Heat reduces synovial fluid viscosity, increases joint flexibility, and enhances circulation through thermal vasodilation.
Operates at the neuromuscular & systemic level. Vibration activates the spinal gate control mechanism to block pain signals while stimulating lymphatic drainage.
The evidence for photobiomodulation in knee osteoarthritis comes from the highest levels of clinical research: systematic reviews, meta-analyses, and large-scale randomised controlled trials.
The landmark Stausholm 2019 meta-analysis (BMJ Open) reviewed 22 RCTs with 1,063 patients. At WALT-recommended doses, pain reduction reached 18.74mm VAS beyond placebo. The Bjordal 2007 analysis of 36 RCTs with 2,434 patients estimated LLLT showed approximately 85% larger pain relief effect than NSAIDs. A 2024 network meta-analysis confirmed LLLT was superior to sham with a large effect size (SMD=0.96), ranking 904–905nm most effective.
Across all major meta-analyses covering over 1,000 patients, zero significant adverse events have been reported for red light therapy. Compare that to the well-documented risks of long-term NSAID or opioid use.
| Parameter | Red Light (PBM) | NSAIDs | Opioids |
|---|---|---|---|
| Pain effect over placebo | 18.7mm VAS | ~10.1mm VAS | Similar to NSAIDs |
| Adverse events in trials | None reported | GI bleeding, renal/CV risk | Addiction, sedation, respiratory depression |
| Drug interactions | None | Numerous | Numerous |
| Suitability for elderly | Excellent | Problematic (GI/renal risk) | Problematic (falls, sedation) |
| Long-term safety | No concerns identified | Increased mortality risk | Tolerance, dependence |
While red light therapy has an excellent safety record, these precautions apply.
Direct eye exposure: Protective eyewear required. Avoid direct retinal irradiation.
Active malignancies: Avoid use over treatment site as a precaution.
Photosensitising medication: Consult your doctor if taking tetracyclines or fluoroquinolones.
Pregnancy: Avoid irradiation over abdomen. Insufficient fetal safety data.
We believe in full transparency. Here is what major clinical bodies currently say about the therapies used in our device.
Issued a strong recommendation (2017) for LLLT as non-invasive treatment for low back pain.
Conditionally recommends thermal interventions for patients with knee osteoarthritis (2020).
Recommends ≥4 J per point at 780–860nm, minimum 3 treatment spots, delivered 2–3 times per week.
Have not yet endorsed PBM as a core OA treatment, largely due to dose heterogeneity in older studies that diluted positive findings.
Knee OA is multifactorial. It affects cartilage, synovial fluid, muscles, nerves, and circulation all at once. No single modality addresses everything, so each therapy targets a different layer.
Boosts ATP, reduces cytokines, stimulates collagen synthesis and growth factors.
Reduces synovial viscosity, increases joint flexibility, enhances thermal vasodilation.
Blocks pain signals, stimulates lymphatic drainage, improves proprioception and muscle strength.
A controlled, double-crossover RCT by Kitay et al. (Osteoarthritis and Cartilage, 2009) with 71 patients demonstrated that combining physical modalities in a single device significantly decreased pain, improved range of motion, and enhanced quality of life.
