Contradictions

One of the unique features of LLLT is that there are very few true contraindications. This means that the therapy can be used in a wide variety of applications and conditions.

1. THYROID GLAND – While research results have been at odds, the current consensus is to avoid LLLT irradiation over the area of the thyroid gland.

2. PREGNANCY – Prudent medical care dictates that LLLT not be performed over the uterus of a known pregnant woman.

3. KNOWN CANCER TUMOR – Although the research is again at odds in this case, the recommendation is to not irradiate over or near a known primary or secondary carcinoma lesion or tumor.

4. RADIATION THERAPY PATIENT – Because LLLT has been documented to have an effect on the human immune system, in patients taking immunosuppressant medications, LLLT is not recommended at this time. Several studies have demonstrated positive effects of LLLT in counteracting radiation therapy nausea; however, more research is needed.

5. TREATMENT OF OVERSYMPATHETIC GANGLIA –The vagus nerves and cardiac regions of patients with known heart disease are not recommended for LLLT.

- ALLEGED CONTRAINDICATIONS -

1. PACEMAKERS – While some have suggested caution in using LLLT in the presence of pacemakers, no evidence has been presented. Because LLLT uses light, no influence on the pacemaker results from its use.

2. EPILEPSY – Pulsed visible light can have an effect on certain individuals susceptible to this condition, however, invisible, non-pulsed laser light (as is provided by the ML-830) has had no reported detrimental effect on seizure-susceptible patients.

3. DIABETICS – While this has been suggested as a contraindication, no evidence has been found to show that LLLT could aggravate symptoms. In fact several studies have shown dramatic improvement in healing of wounds of diabetics with LLLT.

4. CHILDREN – The concerns originally expressed for use of LLLT near growth plates in children have been found to be unwarranted. No detrimental bone growth effect has been documented, and in fact, LLLT in children has been found to be beneficial in pediatric fractures.

- GENERAL PRECAUTIONS -

Because the ML-830 laser emits invisible infrared light, use of it in the area of the face and around the eyes must proceed with appropriate care and caution. Invisible infrared laser light penetrating the eye may cause serious harm after extended exposure. Therefore, the use of the provided protective glasses for the patient and clinician is advised.
