Question 1

When treating a patient with chronic low back pain using low-level laser therapy (LLLT), which parameter is MOST critical to adjust based on tissue depth?

Accepted Answer

Wavelength

Answer

Wavelength determines tissue penetration depth; near-infrared wavelengths (800–1064 nm) penetrate deeper than visible red wavelengths for reaching deeper structures.

Question 2

A patient presents with acute lateral epicondylitis. According to standard laser therapy protocols, the BEST approach is to:

Accepted Answer

Begin with lower doses and increase gradually as acute inflammation subsides

Answer

In acute conditions, starting with conservative lower doses reduces risk of exacerbating inflammation and allows tissue response to guide dose escalation.

Question 3

Which of the following conditions is considered a CONTRAINDICATION for laser therapy over the treatment area?

Accepted Answer

Active malignancy at the treatment site

Answer

Active malignancy at or near the treatment site is a contraindication because laser energy may stimulate cellular proliferation and tumor growth.

Question 4

During a laser therapy session for wound healing, the Arndt-Schulz Law suggests that:

Accepted Answer

Optimal doses stimulate; excessive doses inhibit biological processes

Answer

The Arndt-Schulz Law states that weak stimuli excite physiological activity, strong stimuli inhibit it — meaning optimal dosing is essential for therapeutic benefit.

Question 5

A laser therapist is treating trigger points in the upper trapezius. The MOST appropriate technique involves:

Accepted Answer

Stationary application directly over each trigger point for calculated time

Answer

Trigger point protocols require stationary application over each discrete point for a calculated time to deliver the target dose to that specific location.
