History of laser phototherapy The first laser Hungarian physician and surgeon, Endre Mester, began his pioneering research into laser phototherapy in the 1960s. His groundbreaking work resulted in numerous publications on the outstanding therapeutic successes he observed. Mester's achievements showed the beneficial effects of laser light therapy on traumatised tissues, clearly demonstrating its wide range of therapeutic applications in the field of medicine. At the time of Mester's research, laser technology was in its infancy. The early helium neon gas lasers lacked power, producing output as low as only 0.5 mW to just 2 mW. However, the research and the experimentations continued with rapid technological advances taking place. Soon, semiconductor laser diodes were developed. Laser diodes offer many advantages over the early gas lasers. Laser diodes are small and portable, whilst also practical and long lasting. The scientists soon recognised that there is a minimum quantity of energy (i.e. 2 - 4 J / cm2) that must be delivered to the tissues for optimum therapeutic effects. Amongst important variables to consider are the depth of the treated tissues and the wavelength employed by the laser. It became clear during the research that the laser light is different to the light from other light sources (i.e. infrared lamps). The laser light biostimulates tissues, accelerating biochemical and metabolic processes in cells. The biostimulation effects of laser light play the most important role in healing, rehabilitation and recoveries from many different ailments. The progress in the development of the laser phototherapy continued. In the 1980s, the first pulsed lasers entered the market. At the start of the 1990s, the spectrum of laser therapy devices grew by the introduction of the ‘hard lasers'. The ‘hard lasers' are today used in surgery as the ‘light scalpels' to cut and/or ablate tissues. The ‘hard lasers' are also commonly used to remove tattoos and to permanently remove hair. Laser therapy continues to be popular amongst scientists and researchers. Much of the laser therapy research has been published. There are now over 2500 studies available for reference, including double blind clinical trials conducted worldwide. The excellent therapeutic outcomes achieved by the laser therapy are receiving growing attention from the clinicians and therapists as well as the public. Laser phototherapy established itself as a valued treatment modality, recognised for its efficacy and safety. It is now amongst the essential therapeutic tools used by the modern medical practices, delivering outstanding benefits to the clinicians and to the patients. If you - as a doctor, therapist or patient - are not familiar with laser phototherapy and the positive impact it can have, we can help you to familiarise yourself with its wide therapeutic applications and its great benefits without any obligations on your part. |
