Photobiomodulation (PBM Therapy)

What is PBM?

  • Photobiomodulation Therapy (PBMT) previously known as Low Level Laser Therapy (LLLT) is a laser or LED light therapy that improves tissue repair (skin wounds, muscle, tendon, bone, nerves), reduces inflammation and reduces pain wherever the beam is applied. Usually applied by a technician, treatments typically take 1 – 10 minutes and should be applied two or more times a week.

How it works?

  • PBM works predominately on a protein in mitochondria (cytochrome c oxidase) to increase ATP and reduce oxidative stress. A cascade of mitochondrial and intracellular downstream effects lead to improved tissue repair and reduced inflammation.

How much is enough, how much is too much?

  • There is a dose response: not enough power density and there is no effect, too much and there can be inhibitory effects which can slow down healing and lose the anti-inflammatory effects.

The analgesic mechanism

  • This depends on an PBM overdose; Higher power density PBM >300mW/cm² reduces ATP production in C fibres and A delta fibres resulting in an immediate neural blockade lasting up to approx 24 hr

Benefits of Photobiomodulation Therapy

Heal Tissue

  • PBM Therapy has been shown to stimulate cellular repair for better overall tissue recovery. This can also aid in the prevention of muscle degeneration through muscular dystrophy.
    • Edema and congestion
    • Wounds

Manage Pain

  • PBM has been shown to lessen overall pain levels while stopping pain sooner
    • Osteoarthritis/ hip dysplasia
    • Joint Pain
    • Tendinopathies
    • Joint, ligament, and muscle sprains
    • Neck and back pain
    • Post surgical or rehabilitation pain

Improve Mood & Brain Health

  • PBMT has been linked to increased cerebral blood flow and brain energy metabolism, ultimately leading to diminishing the symptoms of major neurological disorders.
    • PBMT is currently treating degenerative myelopathy in dogs – a condition like MS in people where dogs slowly become paralyzed and require a cart. Studies have show significant improvement and some cure!
