Clinical Applications & Treatment Protocols Flashcards

Laser therapy applied over an area with a metal implant (e.g., titanium plate) requires which precaution?

Answer: Monitor for heat buildup; titanium implants may conduct and concentrate thermal energy

Metal implants can absorb and concentrate laser-generated heat, potentially causing discomfort or tissue damage, so therapists should monitor tissue temperature and use conservative parameters.

Which of the following BEST describes 'biphasic dose response' in photobiomodulation therapy?

Answer: Low doses stimulate and high doses inhibit the same biological process

Biphasic dose response (Arndt-Schulz curve) means that below-threshold and above-threshold doses are ineffective or inhibitory, while optimal doses are stimulatory.

A patient develops an unexpected blister after laser treatment of the forearm. This MOST likely indicates:

Answer: Thermal damage from excessive power density or treatment duration

Blistering indicates excessive heat deposition, suggesting power density or exposure time exceeded safe therapeutic limits for that tissue type.

When developing a laser therapy treatment plan for lymphedema management, which technique is MOST appropriate?

Answer: Scanning technique along lymphatic drainage pathways proximal to distal

Scanning along lymphatic pathways from proximal to distal supports lymphatic drainage by stimulating vessel contractility and reducing fibrotic tissue along the drainage route.

The Maiman point in laser therapy documentation refers to:

Answer: A standardized landmark used to document probe placement

The Maiman point is a standardized anatomical or surface landmark used in documentation to ensure consistent probe placement across treatment sessions.

For treating carpal tunnel syndrome with laser therapy, which approach targets the median nerve MOST effectively?

Answer: Directing laser through the carpal tunnel via the palmar aspect of the wrist

The palmar aspect of the wrist provides direct access to the carpal tunnel, allowing laser energy to reach the median nerve and surrounding structures at the site of compression.

Which OSHA laser safety classification requires mandatory use of laser safety eyewear by both the operator and patient?

Answer: Class 3B and Class 4

Class 3B and Class 4 lasers pose significant ocular hazards and require appropriate wavelength-specific protective eyewear for all persons in the treatment area.
