What is laser therapy?
Laser therapy (LLLT) uses laser radiation to help repair tissue, relieve pain and stimulate acupuncture points. This therapy does not require anesthesia, is non-invasive, painless and can be easily administered in primary care. The incidence of side effects is low and similar to placebo.
Why is laser therapy performed?
It is applied for cases of chronic and acute pain, which can be caused by various pathologies or injuries:
- Arthralgia: gonalgias, epicondylitis, lumbalgia, polyarthritis, etc.
- Traumatology: tendinitis, joint distortions, borsitis, tendinitis, muscle tears, overload pathologies, etc.
- Motor rehabilitation: after surgery or after removal of a cast or splints.
What does laser therapy consist of?
The treatment consists of emitting photons that produce photochemical and photothermal reactions but, given its monochromaticity and high intensity, the body absorbs more energy, thus increasing its biological effects.
The physical effects of this technique are dehydration, heat, coagulation of proteins, evaporation, thermolysis, and mechanical effect by shock waves.
Preparation for laser therapy
Before treatment, a study must be made to ensure that the patient has no contraindications to undergo therapy, such as tumors, pregnancy, neoplasia, hemorrhagic areas, sympathetic system, infected areas or photosensitivity.
Aftercare after the procedure
No specific care is required after the treatment, since it blocks the pain signals transmitted from the brain, which reduces sensitivity. In addition, it also reduces inflammation and increases the production of endorphins and enkephalins, natural chemicals that reduce pain.
Other benefits of laser therapy include improved nerve function, faster wound healing (if applicable), improved blood flow and immune function, increased metabolic activity and acupoint stimulation.
