Low Level Laser Therapy (LLLT) aka Photobiomodulation therapy (PBMT) is the use of laser/LED light to reduce pain and promote tissue healing. Light therapy works on the body’s cells treating the underlying causes of pain rather than simply masking it. It is painless, non-invasive and has no side effects.

There is a vast amount of published research spanning over 30 years from clinical trials (RCTs) and laboratory studies proving numerous beneficial effects across a broad range of medical conditions. With regard to pain specifically, Low Level Laser Therapy / Photobiomodulation Therapy relieves pain by blocking pain nerves, reducing inflammation and healing tissue in and around the painful area. Within 3-4 treatments better blood circulation, less inflammation and revitalised cells means your body can start to heal.

Some of the research shows significant reduction of inflammation equal to or better than NSAIDs (anti-inflammatory drugs) within 2 hours, analgesic effects that last for 48 hours, and healing time of chronic tendinopathies reduced by 70%.

The basic science: When cells are stressed, a compound called nitric oxide (NO) binds to the cell reducing adequate ATP (energy) production and increasing inflammation. When laser light (or LED’s) are applied to the skin the damaged cells in the injured or painful area (below the skins surface) absorb the light displacing NO from the cell. As that energy (ATP) is restored to the cell, oxidative stress is reduced. This puts the cells back on the path to healing the injured area more quickly.

Some benefits of Low Level Laser Therapy / Photobiomodulation Therapy include (but not limited to) the reduction/elimination of:
• Pain both Chronic and Acute
• Joint and muscle inflammation
• Neck and back pain (upper and lower back) especially chronic pain
• Arthritic Pain
• Sciatic pain
• Headache/migraine
• Sports injuries
• Tinnitus
• Fibromyalgia
• Nerve pain in the limbs
• Tendonitis, tennis elbow and golfers elbow
• Frozen shoulder
• Plantar Faciitis
• Carpal tunnel and RSI
• Lymphoedema
• Neuralgia (inc. Trigeminal)
• Muscle sprains and strains
