Cold Laser Therapy

A laser is a light beam that can concentrate high energies. Other types of light energy do not have the special physical characteristics that laser provides. These are coherence and monochromaticity. These factors account for why laser light is superior to other types of light in the field of pain relief and healing. Low power coherent light is applied to injuries and lesions during laser treatment (also referred to as phototherapy and low-level laser therapy) in order to promote healing and relieve pain.

It is used to reduce inflammation, provide pain relief, and speed, strengthen, and quality of tissue repair. Low-level laser technology is a complete system of treating muscle, tendon, ligament, connective tissue, bone, nerve, and dermal tissues in a non-invasive, drug-free modality. Compared to other electrotherapeutic modalities like ultrasound, low-level laser technology has been discovered to have superior healing and pain-relieving effects, particularly when used to treat chronic conditions and the initial stages of acute injuries.

A full system for treating muscle, tendon, ligament, connective tissue, bone, nerve, and dermal tissues using low-level laser technology is non-invasive and drug-free.

Chromophores in the cell membrane and in the mitochondria of the cell absorb photons as they enter the tissue. These chromophores are photosensitizers that produce reactive oxygen species after exposure to light, affecting the mitochondrial respiratory chain and cellular redox states. The photonic energy is transformed into electromagnetic energy within the mitochondria in the form of chemical bonds in ATP (Adenosine Triphosphate).

Laser light must be taken in by intracellular chromophores in order to interact with the living cell. Increased cell membrane permeability results in physiological changes. These physiological changes impact macrophages, fibroblasts, endothelial cells, mast cells, bradykinin, and nerve conduction rates. The way tissues absorb laser light results in clinical and physiological outcomes. The amount of laser energy that reaches the target tissue at the required clinical levels relies on the wavelength of the laser beam and its power. If the laser light was the improper wavelength, it would not be able to reach the target location by penetrating the tissue.

Furthermore, even if a laser is used, it must have sufficient power to deliver the energy into the tissue in order for the target area to experience any potential benefits. Each type of laser releases light with a very distinct wavelength that reacts with the tissue being treated. It also specifically affects the tissue’s chromophores but in a different way.

Any material that can absorb radiation, whether it is colored or explicit, is considered to be a chromophore, intrinsic or extrinsic. Hemoglobin, proteins, nucleic acid, and water are examples of endogenous chromophores. Porphyrins and hematoporphyrins are two exogenic chromophores that are injected into the organism. Because they adhere to the tissue, these substances are referred to as photosensitizers because they make the tissue photosensitive at particular wavelengths.

FDA clearance and CE certification, indicators of European safety and legal conformity, are on Multi Radiance Medical equipment. One should however never shine a laser straight into the eye because all lasers emit high-intensity light.

Users should also be aware of all risks and adhere to the manufacturer’s directions. Before using a device, review the procedure and operating instructions. It is advised against using the laser directly on any neoplastic tissue.

Direct abdominal laser treatments should be avoided by expectant women. Those who have pacemakers should also avoid getting laser treatments in proximity to the heart.
