Practitioners should exercise caution when applying Cool Laser Therapy in the presence of dark tattoos. Tattoos are heavy metal inks injected into the dermis to provide decorative designs for the recipient. The black and dark blue inks, quite often used, will tend to block red and near infrared light from penetrating into the tissue. This build-up of laser light in the dermis (where a lot of the nerve receptors are) will (depending on the power level) cause the patient to react and respond that the laser treatment feels warm or even hot.
Yes. Laser therapy is contraindicated in patients with benign or malignant tumours due to its biostimulating effects. LLLT is known to increase energy production, in the form of adenosine triphosphate (“ATP”), which induces accelerated replication of mitochondrial DNA. Moreover, increased local oxygen and glucose consumption also suggests accelerated metabolism. These effects raise concerns over the further enhancement and spread of the lesion.
Yes. The application of low-level laser light transcranially is safe. To date, there have been no reports of major safety issues or side effects after transcranial laser treatment. Researchers are generating positive results in the treatment of traumatic brain injuries and neurodegenerative diseases such as Alzheimer’s disease and stroke.
It is recommended that you clean the laser probe surface in between patients using isopropyl alcohol.
Yes.Cool Laser Therapy can be applied safely in patients with ICDs. ICDs are prescribed for people who have a faster than normal heart rate, or tachycardia, as well as for patients suffering from ventricular fibrillation. These devices cannot be influenced by photons. The only exception is any light therapy device that also uses electrical stimulation.
The following are reasonable reasons why a patient may feel pain or soreness after therapy:
Avoid treating over the abdominal, pelvic and lower back regions of women who are pregnant. There is concern over interference with the normal development and growth of the fetus. There is, however, no evidence to support the idea of there being any risk in treating distant regions of the body (i.e., upper and/or lower extremities) relative to the uterus.
Yes. Cool Laser Therapy can be applied safely over metal and plastic implants (i.e., plates, rods, pins, nails, wires, etc.). The Theralase laser system is not a heating device, and therefore does not pose a risk of heating the metal.
Cool Laser Therapy can be applied safely in patients with pacemakers. Pacemakers are electronic devices prescribed for people who have an abnormal heart rate (e.g., slower or faster than average, or irregular beating patterns). Their purpose is to ensure a normal heart rate, or to pace the heart.
These devices cannot be influenced by photons. The only exception is any light therapy device that also uses electrical stimulation.
Some authors advise practitioners to avoid Cool Laser Therapy in patients with epilepsy due to the risk of inducing an epileptic seizure. Pulsing visible red light in the 5-10 Hz range may trigger epileptic seizures. This is, however, highly uncommon.
Cool Laser Therapy can be applied to an open wound. The laser probe can either be placed in direct contact with the wound or held just above it if it is too sensitive. If the probe is held at a distance, it is important to consider the energy loss that will occur.
Exert caution when treating over an infected wound as there may be a risk of stimulating bacterial activity. Some studies suggest reduced vitality of microflora and reduced growth of bacteria; other studies describe a positive biostimulating effect on the growth of bacteria; and, other works have observed no effect on bacterial growth.
The transmission of laser light will likely be blocked or attenuated by occlusive wound dressings, so ensure that they are removed prior to treatment, if possible.
