Biological Effects of Laser Therapy

Laser Therapy, an everyday tool

This non-invasive product can have considerable impact on the way you practice medicine.

1) Wavelengths:
√ 640 nm
▪ Superficial
▪ Photo-coagulant
▪ Anti-œdematous

√ 810 nm
▪ Deep
▪ Production of ATP (energy, anti-inflammatory)
▪ Regeneration of muscles and tendons

√980 nm
▪ Deep
▪ Production of ATP
▪ Release of oxygen absorption
▪ Analgesic
▪ Optimal absorption of water and strong absorption by haemoglobin
▪ Action on the peripheral nervous system (Gate Control type), e.g. Heat

2) General instructions for treatment set-up:
Clean hair: if possible, cut the fur/coat shorter. (50 to 90% of light can be absorbed by the hair)
Hair and skin colour are important factors as melanin absorbs the energy from short wavelengths.
Prior to treatment ensure all PPE is worn: Laser Glasses.
During a treatment ensure that your patient is positioned correctly and comfortably.
During the treatment continuously move the handpiece to cover a large area; whilst monitoring the temperature of the treatment area with your other hand.

3) Techniques for the movement of the handpiece:
Move from proximal to distal
You can move the handpieces in a point to point movement. This treatment can take time. Therefore, most people apply the laser in a scanning motion.
Techniques of applying the probe
Contact: Using the massage ball applicator. Care must be taken on bony prominences or injured tissue as can cause pain.
Non-contact: Using the non-contact applicator head.
You can hold the applicator head against the skin, but at no point does the laser beam directly come into contact with the tissue.
