Laser Therapy Flashcards
What is the acronym for laser?
Light amplification by stimulated emission radiation
Phototherapy involves which two forms of treatment?
Low level lasers (Cold therapy) and light emitting diodes (LED)
Where lasers fall on the electromagnetic spectrum
Visible light
What energy level is light at during baseline and when excited?
E1
E2
E triangle will stimulate the photons at level E2 creating energy that is what three things?
Monochromatic, coherent, and collimated
Lasers emit how many kinds of wavelengths?
1
What is the clinical significance of coherence?
Localized application
What is the clinical significance of collimation
Ability to control depth and effect of laser application
One are three effects of lasers that are multifactorial
Tissue, density, and pigmentation
What kind of proteins absorb laser energy
Hemoproteins
Three physiological reactions to laser treatment
Increase bloodflow
decreased edema/inflammation
increased osteoblastic activity and accelerated callus formation
Three clinical indications for laser therapy
Wound healing: pressure, diabetic, venous and arterial ulcers
Acute and chronic joint and muscle pain
Fracture healing
For areas to avoid doing laser therapy
Vegas nerve/nerve roots
Mediastinum
Epiphyseal plates
Sympathetic ganglia
What type of protective equipment should be worn during laser therapy
Goggles for the PT and the patient
During the clinical application of SCANNING how close should be the spray-painted motion be over the wound?
1 cm
