What is the 'Arndt-Schulz Law' and how does it apply to laser wound healing dosing?
Answer: Low doses stimulate, optimal doses maximize effect, and excessive doses inhibit or damage tissue
The Arndt-Schulz Law states that small stimuli excite biological activity, stronger stimuli promote it, and very strong stimuli inhibit or destroy it—directly guiding laser therapy dosing to avoid overdose.
Why should laser therapy be applied with caution directly over actively infected wounds with cellulitis?
Answer: Laser therapy may stimulate bacterial proliferation and spread infection if applied to an actively infected area without antibiotic management
In active infections, laser's bio-stimulatory effects could potentially increase local metabolic activity in a way that promotes bacterial spread; infection should be managed before or alongside laser therapy.
Which wound characteristic is assessed using the PUSH tool (Pressure Ulcer Scale for Healing)?
Answer: Wound surface area, exudate amount, and tissue type to track healing progress over time
The PUSH tool evaluates wound surface area, exudate amount, and tissue type (necrotic, granulation, epithelial) to create a numeric score for tracking pressure injury healing over time.
What is epithelialization in wound healing and how does laser therapy support it?
Answer: It is the migration of epithelial cells across the wound surface to restore skin integrity; laser stimulates keratinocyte proliferation to accelerate this
Epithelialization is the final closure of a wound by migrating keratinocytes; photobiomodulation stimulates keratinocyte proliferation and migration to accelerate this critical healing step.
When measuring wound healing progress after laser therapy sessions, which objective measurement is most clinically relevant?
Answer: Serial wound area measurements (length × width) and wound bed tissue type assessment
Serial wound area measurements combined with wound bed assessment (granulation vs. slough vs. epithelial coverage) provide objective, quantifiable data on healing trajectory.
What is the clinical significance of 'biofilm' on chronic wounds in the context of laser therapy treatment?
Answer: Biofilm is a protective bacterial community that resists antibiotics and impairs wound healing; it must be addressed as laser alone cannot penetrate mature biofilm
Bacterial biofilm forms a protective matrix that dramatically reduces antibiotic efficacy and impairs healing; chronic wound management must include biofilm disruption strategies alongside laser therapy.
