Light has been considered to have healing and stimulating effects on the human body since the dawn of humankind. Cold lasers follow this line of thought and are used in the treatment of injuries related to the human tissue. Treatment effected by cold lasers is known as ‘bio-stimulation’, in which laser beams energize cells and accelerate tissue repair by activating the metabolic and healing processes.
Cold lasers emit infra red light over or into the injured tissues through the skin and underlying tissue layers. The light rays of cold lasers do not have thermal effects and does not heat up the treated tissues. It is called cold as the laser beams penetrate living tissues without causing any trauma, cellular damage, pain, or side effects.
These lasers are completely non-invasive and operate at much lower energy levels than invasive surgical lasers capable of cutting through the tissues. Cold lasers commonly used in clinics operate at outputs well below hundred MW, whereas surgical lasers have high-energy outputs ranging between 3000 and 10000 MW. Cold laser treatments are considered safe, effective, painless, and free from side effects. It has proved very effective in mitigating chronic pain symptoms, inflammation as well as accelerating wound healing, tissue repair, and regeneration.
Cold laser treatment techniques and processes have been well researched and documented. The number of reports related to cold laser treatment and their effectiveness is well over two thousand along with hundreds of books written on the technology by eminent scientists and medical researchers.
The growing incidence of obesity among the population has forced many people to undertake daily activities such as walking, cycling, running, or jogging, and to participate regularly in a variety of games or sports, ranging from gymnastics, fitness training, tennis, football or water sports to skating, skiing, and many other outdoor or indoor sporting initiatives. These activities may often lead to injuries related to soft tissues such as muscles, ligaments and tendons or they can involve trauma to the bones. Cold lasers are used for the treatment of such complications.
