Influence of the laser beam wavelength on the gonoarthrosis treatment: a preliminary comparative study

Abstract

A comparative study on four groups of patients which have been exposed to laser radiation was performed. Three wavelength were used (633, 670 and 830 nm). The fourth group received only laser placebo. Every group is composed by 20 people homogeneously selected from the point of view of age, sex and clinical and paraclinical parameters. The irradiation dose was kept almost the same, i.e. 15 J/cm2. The dependence of subjective and objective indicators on the laser wavelength were put into evidence.
