LEPT has been shown by studies to speed up healing of skin wounds, muscle strains, and injured nerves. Light of different characteristics is useful for different effects. Laser also can decrease pain very rapidly. It is a painless, gentle form of therapy that is favored by athletes and sports teams. It can shrink swollen joints and even give relief in arthritic joints. Research is ongoing to determine if the therapy actually slows down the progression of arthritis.
Recent advances have allowed the use of home units for daily treatments.
I use LEPT-lasers in my practice with very good effect.
