Flex Therapist CEUs

1. In recent years, Low-Level Laser Therapy (LLLT) has broadened to include light-emitting diodes and other light sources, and the range of wavelengths used now includes many in the red and near infrared. This field is also known as which of the following?

A. Photoillumination B. Biolaser C. Photobiomodulation D. None of the above

2. LLLT is referred to as "low level" because of its use of light at energies that are low compared to other forms of laser therapy that are used for ablation, cutting, and thermally coagulating tissue.

A. True B. False

3. Which optical property of tissue is responsible for the desired effects of LLLT?

A. Absorption B. Reflection C. Scattering D. All of the above.

4. Within the cell, there is strong evidence to suggest that LLLT does which of the following:

A. Acts on the mitochondria to increase adenosine triphosphate production B. Modulation of reactive oxygen species C. Induction of transcription factors D. All of the above.

5. Among its many effects, LLLT has been shown to cause vasodilation by triggering the relaxation of smooth muscle associated with endothelium, which is highly relevant to the treatment of joint inflammation.

A. True B. False

6. Which of the following ranges of wavelengths of light represents the maximized range for effective tissue penetration?

A. 700-770 nm B. 600-1070 nm C. less than 600 nm D. greater than 1070 nm

7. LLLT is used for which of the following three main purposes?

A. To promote wound healing, tissue repair, and prevention of tissue death B. To relieve inflammation and edema C. As an analgesic and treatment for neurological problems D. All of the above

8. A study of 88 randomized controlled trials indicated that LLLT can significantly reduce pain and improve health in all of the following chronic joint disorders, EXCEPT?

A. Osteoarthritis B. Patellofemoral pain syndrome C. Plantar fasciitis D. Mechanical spine disorders
