Skin Barrier
Skin barrier hinders deep penetration of lasers
Until now it was difficult – if not impossible – to achieve sufficient laser dose supply in deep tissue for irradiation of spinal nerves or within joints as externally applied laser sources are absorbed in the skin by more than 70% in the first millimetres of tissue already. Therefore, external laser therapy is very limited in achieving measurable energy supply deep in the tissue at the origin of pain.

The new technology finally allows the user to apply a direct fiber-optic treatment very close to nerve roots at the spine or directly within damaged joints. Thus, injured or damaged tissue (e.g. nerve, cartilage, bone) is exposed to direct irradiation with high energy dosage.

There are several publications available proving the regeneration of cartilage or nerve tissue by use of low power laser therapy (by in-vitro and in-vivo experiments).

Using this technique, therapeutic results can be improved significantly due to a highly increased penetration depth of up to 12 cm. Also, green and blue lasers, which are normally already absorbed on the surface of the tissue, can now be used deeper in the tissue, leading to anti-inflammatory effects on damaged tissue.

The direct irradiation within a joint or at the spine can be combined with regenerative or anti-inflammatory injections (i.e. hyaluronic acid or platelet-rich plasma) directly prior to irradiation. The same canula can be used for both injection and irradiation so only a single puncture is necessary. The resulting therapeutic effects are much better than injections of hyaluronic acid or PRP alone.

This treatment protocol has a high success rate among patients and can be done quickly.

Effects of Different Laser Wavelengths:

Red Laser:

  • Increase of cell activity and microcirculation
  • Regeneration of damaged tissue structures

Green Laser:

  • Anti-inflammatory effects
  • Effective in treatment of pain connected to inflammations and swellings

Blue Laser:

  • Strong anti-inflammatory effects
  • Effective in wound-healing
  • Immediate reduction of acute pain

Red laser light is most effective in treating chronic joint or spine syndromes, green and blue lasers are used in acute inflammations.

Laser Therapies combined with PRP (Platelets-Rich Plasma)

Torn tendons, muscles and ligaments plague professional and amateur athletes in many types of sports. Same problems are seen with repetitive and prolonged activities, work can be a great example here. In attempts to help heal the wounded tissue, regenerate cartilage and osteoarthritis of the joints some athletes, both amateur and professional, have turned to platelet-rich plasma (PRP) therapy. For the treatment, a small vial of a patient’s blood is taken. That blood is span in a centrifuge to separate the platelet-rich plasma from the other components. Then the concentrated platelets are injected at the site of the patient’s injury or deterioration site. The growth factors that platelets secrete spur tissue recovery, stimulate cell production, angiogenesis and formation of connective tissue. Also, proliferation of stem cells, broblasts and mononuclear leukocytes is induced.

Here at Parkwood Photodynamic Therapy, injections of PRP are combined with intra-articular or interstitial laser therapy. The blue, green, infrared and red spectrum of light is introduced together with PRP.

The end result is an extremely strong anti-in ammatory effect and very robust healing. Total relief of pain and normal function are obtained often with on treatment. There are not known side effects of the treatment.
