CLT Treatment Planning & Protocols 2

Question 1

When calculating dosimetry for low-level laser therapy (LLLT), which parameter directly determines the energy density (fluence) delivered to tissue?

Accepted Answer

Power density multiplied by treatment time

Answer

Fluence (J/cm²) is calculated by multiplying power density (W/cm²) by treatment time (seconds).

Question 2

A patient presents with acute tendinitis. According to standard LLLT protocols, which energy dose range is most appropriate for an acute inflammatory condition?

Accepted Answer

1–4 J/cm²

Answer

Acute conditions typically respond to lower doses of 1–4 J/cm², while chronic conditions may require 4–12 J/cm².

Question 3

Which wavelength range is most effective for targeting deep musculoskeletal tissues (3–5 cm depth)?

Accepted Answer

780–1000 nm (near-infrared)

Answer

Near-infrared wavelengths (780–1000 nm) penetrate deepest into tissue, reaching musculoskeletal structures at 3–5 cm.

Question 4

When treating a large surface area wound with laser therapy, the therapist should apply which scanning technique to ensure uniform coverage?

Accepted Answer

Grid or scanning method moving across the treatment zone

Answer

A grid or scanning technique ensures that the entire wound surface receives a uniform dose of therapeutic energy.

Question 5

A patient taking photosensitizing medications (e.g., tetracycline) requires laser therapy. What is the most appropriate protocol adjustment?

Accepted Answer

Reduce dose, avoid UV-visible wavelengths, and monitor skin response

Answer

Photosensitizing drugs increase the risk of adverse skin reactions; dose reduction and wavelength selection away from UV-visible range are essential.
