OBT Clinical Application & Patient Management 4

Question 1

A patient with Fitzpatrick skin type VI is receiving UV-based optical therapy. Compared to a type I patient, which adjustment is most appropriate?

Accepted Answer

Start at a lower MED percentage since darker skin may absorb more UV superficially

Answer

Higher melanin content in darker skin types alters UV absorption, requiring individualized MED testing and typically lower initial doses to prevent adverse reactions.

Question 2

In the context of OBT wound care, what does the term 'photoactivation of fibroblasts' refer to?

Accepted Answer

Stimulating connective tissue cells to proliferate and produce collagen via light absorption

Answer

Photoactivation of fibroblasts describes how therapeutic light triggers increased fibroblast proliferation and collagen production, accelerating tissue repair.

Question 3

Which outcome measure is most appropriate for objectively tracking OBT effectiveness in a patient being treated for chronic neck pain?

Accepted Answer

Numeric Pain Rating Scale (NPRS) combined with cervical range of motion measurements

Answer

NPRS provides subjective pain intensity data while cervical ROM offers an objective functional metric, together forming a comprehensive outcome assessment.

Question 4

A sports medicine OBT clinic is treating an athlete 48 hours post-hamstring strain (Grade I). What is the primary therapeutic goal at this stage?

Accepted Answer

Modulate inflammation and reduce pain to facilitate early protected mobility

Answer

At 48 hours post-strain, OBT aims to modulate the inflammatory response and reduce pain, supporting controlled early mobilization without exacerbating injury.

Question 5

Which of the following best describes the concept of 'fluence' in optical beam therapy dosimetry?

Accepted Answer

Total energy delivered per unit area (J/cm²)

Answer

Fluence (J/cm²) is energy density — total energy delivered divided by the irradiated area — and is the primary dose metric in OBT dosimetry.
