Physics & Light
This property describes laser light being one specific wavelength.
What is monochromatic?
Primary chromophores that absorb laser energy.
What are hemoglobin and melanin?
The total energy delivered is measured in this unit.
What is J/cm2?
What is grid technique?
T or F: Super pulsing helps photons penetrate deeper.
False
This property refers to laser light waves traveling in phase.
What is coherent?
LLLT is included in the clinical practice guidelines for all conditions except:
Achilles tendinopathy
Formula used to calculate energy density.
What is Power x Time/ Area?
What is scanning technique?
Type of tissue that often shows no response to LLLT.
What is healthy tissue?
The positive portion of a shockwave is defined as
Compressive phase of the wave
When reporting dose, all of the following should be included.
Wavelength, area treated, and total energy applied
This parameter determines how fast energy is delivered.
What is power (watts or mW)?
Joint position recommended during treatment.
What is open-packed position?
Laser vs control in tendinopathy studies shows this result.
What is no significant difference?
RPW energy __ as it travels through tissue.
Dissipates
Immediate reduction in pain complaints while treating patients with a high power laser is primarily due to changes in:
Peripheral nerves
Depth of programmed energy is defined by stand offs
Focused shockwaves
Pulse frequency used for tissue healing.
What is 1-20 pps?
This type of bias may occur when patients report improvement simply from receiving a treatment like LLLT.
What is the placebo effect?
Depth of penetration is impacted primarily by which device related variable?
Wavelength
Contraindications of laser therapy (list some):
Abdominal or lumbosacral points in pregnant females, epiphyseal lines in children, thoracic region or over the pacemaker itself in patients with pacemakers, patients who are taking drugs that have heat or light sensitive contraindications
Reducing heat on the surface of the skin.
The reason that high power laser can impact both acute and chronic pain is primarily because:
Both acute and chronic pain sensory nerves are impacted by high intensity light.
What would be appropriate choices for setting up a plan of care to address tendinopathy? (There are several options you can say one)
Incorporating high load, long duration activities to laod the injured tendons
