Laser therapy has been used for many years. At first, cold or low power lasers were used, but at present time high performance lasers have been used in recent decades. High-powered lasers can penetrate deeper into the tissue than previous lasers (or low-powered lasers), deliver more energy to the area of treatment and have greater efficacy and shorter treatment times.
Powerful lasers are 52 times more powerful than conventional lasers and have an effective penetration depth of more than 6 cm, whereas conventional cold or low power lasers have an effective penetration depth of half cm and can be useful in the treatment of superficial and small tissues.
The benefits of high power laser
Laser therapy uses two types of pulse and continuous mode. The continuous laser treatment is applied to the nerve fibers to block and to the control the pain signals. Another method used is pulsed mode where laser beam is applied to the affected area and reduces inflammatory substances and mediators in the affected area and by stimulating the lymph node to drain fluid into the area and eliminate edema. Most importantly, laser stimulation of chromophores in cell mitochondria increases ATP production and consequently increases cellular energy and restores damaged tissue structure. Therefore, accelerating the healing process in connective tissue cells improves the healing of soft tissues (muscle, ligament, disc, etc.) and improves the function of nerve fibers by reducing recovery time and sensory and motor nerve recovery.
High power laser therapy indications:
Treatment of inflammatory diseases, spinal pain, sports injuries, ligament&meniscus injuries, muscle injuries, bursitis, nerve pain, etc.
Many patients have the question what are the side effects of laser therapy? A laser is a light, that is, a set of photons of the same frequency and wavelength at the same time, so it does not have any side effect. The laser is powerful, painless and safe, and during the treatment has a mild thermal effect due to the dilation of the patient’s blood vessels, which in most cases is accompanied by a deep relaxation.
Side effects and contraindications
- Light sensitivity (porphyria)
- Active tumors
- Pacemakers (cardiac)
No topical lotions or ointments should be used during laser therapy. Laser beams on the gonads (testicles, ovaries) and thyroid should not be irradiated. During high-power laser therapy, eye protection glasses are required to prevent laser radiation to the eye.
