LASER Flashcards
1
Q
What is LASER
A
- Light
- Amplification of
- Stimulated
- Emissions of
- Radiation
2
Q
Cold Lasers
A
Low-Level laser therapy
3
Q
Class/Power/Effects
A
Class: 3B
Power: 5 to 500 mW
- can cause permanent eye injury with brief exposure
- Direct viewing of the beam should be avoided
- Viewing of the diffuse beam reflected from the skin is safe
- can cause minor skin burns with prolonged exposure
4
Q
Physical properties
A
- Light source: emission from photodiodes
- Monochromaticity: single specific wavelength and frequency (targeted to wavelength-dependent chromophores in body)
- Coherence: Temporal and Spatial
- Collimation: Light does not diverge; transmitted in parallel; Propagate over distance
5
Q
Effects of Laser
A
- Promote Adenosine Triphosphate production
- Promote collagen production
- Modulate inflammation
- Inhibit bacteria growth
- Promote Vasodilation
- Alter nerve conduction velocity and regeneration
6
Q
Clinical Indications
A
- Tissue healing
- Lymphedema
- Neurological conditions: Carpal tunnel syndrome, Diabetic peripheral neuropathy
- Pain Management: Lateral epicondylitis, Chronic low back and neck pain, Trigger points, Delayed-onset muscle soreness
7
Q
Adverse Effects
A
- Mostly no adverse effects reported
- Reports of transient tingling, mild erythema, a burning sensation, an increased pain, numbness, and skin rash
- Primary hazard: irridation of the eyes
8
Q
Parameters
A
- Wavelength: between 500 and 1100 nm
- Probes: IR (30-40mm deep), Red (5-10mm)
- Power: between 5 to 500mW
9
Q
Energy Density
A
- treatment dose
- amount of energy per unit area J/cm2
- Power x Time
10
Q
Most recommend for energy density
A
- Using lower doses for acute and superficial conditions
- Using higher doses for chronic and deeper conditions
- Start therapy at lower end of the recommended dose range
11
Q
Application Techniques
A
- Patient should not feel anything
