Modalities
Question | Answer |
---|---|
Light therapy applicator with multiple diodes that may be any combination of laser diodes, LEDs or SLDs | Cluster Probe |
Occurs when a photon hits an atom that is already excited | Stimulated Emission |
Light source that uses semiconductor diode technology to produce high power light in a narrow frequency range | supra luminous diode |
electromagnetic radiation with wavelength from | ultra violet radiation |
light that spreads; the opposite of collimated | divergent light |
light of single frequency, wavelength, and color | monochromatic |
electromagnetic radiation that can penetrate cells and displace electrons from atoms or molecules to create ions | ionizing radiation |
light in which all the waves are in phase with each other, lasers produce coherent light | coherent light |
total amount of electromagnetic energy delivered per unit area over the entire treatment time | energy density |
light with parallel waves | directional light |
light-absorbing parts of a molecule that give it its color | chromophores |
number of waves per unit time, generally measured in hertz | frequency |
application of shortwave or microwave electromagnetic energy to produce heat within tissues, particularly deep tissues | diathermy |
the length of a wave of light from peak to peak determines frequency and color | wavelength |
variability of light intensity that occurs when a coherent light illuminates a rough object | speckling |
stimulatory or inhibitory effects on the body caused by light phototherapy; the therapeutic use of light | photobiomodulation |
directional light (collimated) is light with parallel waves | true |
monochromatic | laser |
used primarily to treat psoriasis | UV light |
POC states light therapy for superficial heat, the best choice is | infrared |
unite of measurement of POWER | milliWatts (mW) |
Energy equation | power x time |
giving an inservice to your clinical instructor on light, you tell them the range of power used for light is | 5-500 mW |
treating chronic soft tissue inflammation with light therapy, the dose range would be ? than for chronic arthritis | higher |
what is a contraindication for light therapy | treatment area is the sternocleidomastoid |
non-thermal effects of light | inhibits bacterial growth |
treating a pt with UV, erythema should disappear with ? after exposure | 24 hours |
erythema is | redness of the skin |
it is ok to begin treatment with sunglasses | false |
