Targeted deep action with laser light
Treatment with our therapeutic lasers utilizes the same action as mud packs or heat lamps: They generate heat and thus promote local blood circulation.
Their major advantage over those conventional therapies lies in the concentrated energy delivery of non-invasive laser light with high penetration depth.
This targeted deep action makes Reimers & Janssen lasers particularly suitable as a complementary measure in physical therapy for the treatment of:
- Muscular tension
- Joint and functional disorders
- Pain in the musculoskeletal system
Deep penetration with infrared
The wavelength of the light determines which structures absorb it and what biochemical effects it can have in tissue.
Violet and blue light are strongly absorbed by hemoglobin and melanin in the upper layers of the skin, and therefore only penetrate 1–2 mm deep. They have an antibacterial effect and are used to treat skin conditions such as acne, psoriasis, eczema, and wounds.
Infrared light penetrates deeper into the tissue, reaching muscles, tendons, and joints. That is why our lasers use those wavelengths specifically. Studies show that this activates cellular mechanisms, promoting cell regeneration and tissue repair.
Cellular mechanisms
Central to the effect is light, which consists of tiny energy packets called photons. These photons are absorbed by the enzyme cytochrome c oxidase in the mitochondria, which stimulates the production of ATP (adenosine triphosphate).
ATP provides cells with the energy needed for essential processes such as tissue repair and the formation of new cells—both crucial to the healing of muscles, skin, and nerves.
An example: muscle tissue
For muscle fibers, the energy supplied by ATP enables the interaction between actin and myosin filaments, which is essential for both muscle relaxation and muscle contraction. It also supports nerve impulse transmission and chemical synthesis.
In addition, increased mitochondrial activity promotes the release of nitric oxide, which dilates blood vessels, improves blood flow and microcirculation, and enhances oxygen supply. That helps to reduce inflammation, lower oxidative stress, and accelerate the breakdown of metabolic byproducts like lactate, which prevents damage caused by reactive oxygen species (ROS).
