MuscleLight uses photobiomodulation (PBM), a therapy with red and near-infrared light. These wavelengths reach from millimeters to centimeters into tissue, where they are absorbed by mitochondria. The result is increased ATP (the cell’s energy fuel), which triggers natural healing responses- reducing inflammation, enhancing blood flow, and accelerating tissue repair.
Proven Benefits
- Speeds healing of blood vessels, cartilage, and soft tissues by boosting cell energy, building collagen, and reducing swelling especially helpful for injuries and Plantar Fasciitis (PF).
- Eases swelling and pain by improving blood flow, repairing cells, and reducing stress in tissues great for joints and PF heel pain.
- Improves strength and stamina by activating muscles, enhancing coordination, and delivering more oxygen to muscles supporting performance and lowering PF strain risk.
- Works on any body part shoulder, knee, back, or foot with Plantar Fasciitis by repairing cells, increasing circulation, reducing swelling, and activating muscles for easier movement and less discomfort.

Who uses it
Photobiomodulation has been trusted for decades by:
NASA – originally to support wound healing and recovery in space
Olympic teams and elite athletes – to boost performance and recovery
Hospitals and clinics worldwide – for pain management and rehabilitation
Physiotherapists and health professionals – as a safe, non-invasive therapy
Scientific Studies
Parameters and Effects of Photobiomodulation in Plantar Fasciitis: A Meta-Analysis and Systematic Review
PMID: 31107161
The study concludes that photobiomodulation (red/infrared light therapy) reduces pain and improves foot function in chronic plantar fasciitis, but the ideal treatment settings (dose, wavelength, frequency) remain unclear and need further research.

Clinical efficacy of low-level laser therapy in plantar fasciitis: a systematic review and meta-analysis
PMID: 30653125
Low-level laser therapy (LLLT), using red or near-infrared light, significantly reduces heel pain in plantar fasciitis, with benefits lasting up to 3 months after treatment.

Effect of low-level laser therapy on pain and disability in patients with plantar fasciitis: a systematic review and meta-analysis
PMID: 34847470
Low-level laser therapy (LLLT) can reduce pain in the short term (0–6 weeks) in plantar fasciitis patients, so it may be considered as part of patient care.

Low-Level Laser Therapy at 635 nm for Treatment of Chronic Plantar Fasciitis: A Placebo-Controlled, Randomized Study
PMID: 25769363
Low-level laser therapy (at 635 nm), applied twice a week for 3 weeks (6 sessions total), led to a statistically significant reduction in heel pain (mean VAS improvement ~ 29.6 vs ~ 5.4 in placebo) and improved foot function, compared to placebo.

Research shows that red and near-infrared light therapy can safely reduce heel pain and improve walking in people with plantar fasciitis, with relief lasting for several months. The light works by helping cells make more energy, improving blood flow, and calming down inflammation so the tissue can heal. Different studies used slightly different light settings, but overall the results are clear: this type of therapy is an effective, non-invasive way to ease foot pain(plantar fasciitis).
