Following NASA's innovation in the 1990s with Light Emitting Diodes (LEDs) that emit a specific narrow light spectrum, LED Therapy (LEDT) showed significant potential. [1] The high precision of narrow-band LED therapy enabled its first use in clinical practices. The commonly used lights in LEDT are blue, red, green, yellow, and infrared (IR). [1]
Cinema therapy is defined by Segen's Medical Dictionary as: A form of therapy or self-help that uses movies, particularly videos, as therapeutic tools. Cinema therapy can be a catalyst for healing and growth for those who are open to learning how movies affect people and to watching certain films with conscious awareness.
LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have enabled making devices with ever-shorter wavelengths, emitting light in a variety of colors. LEDs are usually built on an n-type substrate, with an electrode attached to the p-type layer deposited on its surface.
The following terms are accepted as alternatives of low level light therapy term: LLLT, laser biostimulation, laser phototherapy, low-level laser therapy, low-power laser irradiation, low-power laser therapy, and photobiomodulation therapy. The term photobiomodulation therapy is considered the preferred term by industry professionals.
For each half-cycle, part of the LED emits light and part is dark, and this is reversed during the next half-cycle. The efficiency of this type of HP-LED is typically 40 lm/W. [54] A large number of LED elements in series may be able to operate directly from line voltage. In 2009, Seoul Semiconductor released a high DC voltage LED, named ...
Electrotherapy is the use of electrical energy as a medical treatment. [1] In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. [2] Electrotherapy is a part of neurotherapy aimed at changing the neuronal activity. [3]
Slovenian filmmaker Sonja Prosenc is prepping her fourth feature, an untitled drama about “sisterhood and female liberation” that follows on the heels of her Tribeca premiere “Family Therapy ...
Light therapy for skin conditions like psoriasis usually use 313 nanometer UVB though it may use UVA (315–400 nm wavelength) or a broader spectrum UVB (280–315 nm wavelength). UVA combined with psoralen, a drug taken orally, is known as PUVA treatment. In UVB phototherapy the exposure time is very short, seconds to minutes depending on ...
