Low-level laser therapy (LLLT), cold laser therapy, photobiomodulation (PBM) or red light therapy is a form of medicine that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to the surface of the body.
The best cold laser therapy devices cater to inner and outer wellness in equal measure. Here's exactly what to know about the tools and where to shop them.
Endovenous laser treatment (ELT) is a minimally invasive ultrasound-guided technique used for treating varicose veins using laser energy commonly performed by a phlebologist, interventional radiologist or vascular surgeon.
Lasers have many uses in medicine, including laser surgery (particularly eye surgery), laser healing (photobiomodulation therapy), kidney stone treatment, ophthalmoscopy, and cosmetic skin treatments such as acne treatment, cellulite and striae reduction, and hair removal.
Laser therapy can be used alone, but most often it is combined with other treatments, such as surgery, chemotherapy, or radiation therapy. In addition, lasers can seal nerve endings to reduce pain after surgery and seal lymph vessels to reduce swelling and limit the spread of tumor cells.
ESWT is used in physical therapy for pain reduction, increase in metabolism at the cellular level, revascularisation, and recovering normal muscle tone following various disorders. The use of ESWT was demonstrated in patients with frozen shoulders compared to therapeutic ultrasound with exercises.
Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, photorejuvenation, and laser surgery. The word laser stands for "light amplification by stimulated emission of radiation".
Hungarian physician Endre Mester (1903–1984) was a pioneer of laser medicine, especially the use of low level laser therapy (LLLT). In 1967, only a few years after the first working laser was invented, he started his experiments with the effects of lasers on skin cancer.
Low-level laser therapy has been shown to reduce pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients that experience chronic neck pain. Low quality evidence suggests that cognitive-behavioural therapy may be effective at reducing pain in the short-term. [15]
A range of lasers such as erbium, dye, Q switch lasers, and CO 2 are used to treat various skin conditions including scars, vascular and pigmented lesions, and for photorejuvenation. The laser surgery for dermatology often bypasses the skin surface.
