Study Notes
Light Therapy
- Light therapy is a clinical therapeutic intervention modality
- It increases cellular activity during the healing process
- It has few known contraindications
- Techniques focus on lasers and light-emitting diodes (LEDs)
Objectives
- Identify different light therapies, specifically lasers and LEDs
- Explain the physical principles used to produce laser light
- Compare helium neon, gallium arsenide, and gallium aluminum arsenide low-power lasers
- Analyze therapeutic applications in wound healing, soft-tissue healing, edema, inflammation, and pain reduction
- Demonstrate application techniques for low-power lasers and LEDs
- Describe laser classifications
- Incorporate safety considerations in laser use
- Be knowledgeable about precautions and contraindications for low-power lasers
Physics of Lasers
- Lasers are a form of electromagnetic energy
- Light energy is transmitted through space as waves containing photons
- Each photon has a definite amount of energy that depends on its wavelength
- Lasers are characterized by coherence, monochromaticity, and collimation
- Coherence: all photons are in phase and have the same wavelength
- Monochromaticity: all photons have the same wavelength
- Collimation: photons travel in parallel, concentrated beam
Types of Lasers
- Lasers have various gain mediums, including crystals, glass, gases, semiconductors, liquids, and chemicals
- Classified as high-power (hot) or low-power (low-level)
- High-power lasers are used in surgery and various medical specialties
- Low-power lasers are used for wound healing, inflammation, pain, and other medical conditions
Common Low-Level Lasers
- Gallium aluminum arsenide (GaAlAs)
- Helium neon (HeNe)
- Gallium arsenide (GaAs)
Laser Applications
- Wound healing: stimulates tissue repair, reduces inflammation, and decreases scar tissue
- Pain relief: treatment for various pain conditions, including musculoskeletal pain
- Inflammation: reduction of inflammation, edema
- Orthopedic conditions: may improve bone healing, and reduce muscular fatigue
- Other conditions: treatment for various other medical conditions
LED Therapy
- LED therapy uses LEDs that generate light through semiconductors
- LED light is non-coherent
- LED applications include wound healing, pain relief, and inflammation
Treatment Parameters
- Treatment parameters include wavelength, peak power, average power, pulse rate, irradiance, energy, energy density (fluence), time of exposure (irradiation), and frequency.
