Introduction to LLLT Therapy Technology
In the late 1960s, medical researchers started utilising low-power laser beams that had non-thermal effects on human tissue for the purpose of laser biostimulation. The earliest cases that were documented were slow-healing ulcers. Ongoing, objective research confirms the effectiveness of this low-level laser therapy, or “LLLT.”Clinicians conducting trials discovered that the best laser for managing chronic pain is 830 nm. In the case of soft tissue trauma, LLLT is effective. Damage to the deep, delicate layers of tissue beneath the skin’s surface, such as the muscle, nerve, lymphatic, and vascular tissues, is what these kinds of injuries entail.
Oedema, a thin or watery fluid in tissue gaps or cell interstices, is the typical way the human body “splints” an injury caused by soft tissue damage. On the other hand, excessive oedema results in swelling that prevents the injured tissue from moving.Pain from these injuries comes in two varieties. The first is the actual, traumatic pain from the wound, and the second is the discomfort that follows from the swelling. The lymphatic system, which keeps the body’s fluid balance, is the primary focus of LLLT, and the laser light also aids in absorbing the extra oedema. Thus, LLLT offers alleviation in two different ways.
Human tissue absorbs laser wavelengths between 820 and 840 nanometres (nm) at very low rates. This indicates that at such frequencies, laser light penetrates deeply.
