title: [Experimental selection of best physical and application parameters of ultrasound in the treatment of venous crural ulceration].
abstract: Venous crural ulceration typically affects elderly people, frequently burdened with other diseases which provide counter-indications for surgery. With those patients in mind, search for new efficient methods to treat the disease is under way. The goal of the paper was to evaluate the impact of ultrasound at two power densities from the range commonly used, 0.5 W/cm2 and 1 W/cm2, on the healing of crural ulceration. The patients admitted to the experiment were divided onto two groups. In group A the density of 1 W/cm2 was used; in group B--0.5 W/cm2; in group C traditional methods were used. Progress was evaluated in all the groups once in a week and after treatment, in terms of the change of the area, volume, suppurate area and granulation. The rate of area change was highest in group B, although it was only statistically significant in comparison with group A. Along with the area change, the volume of the ulceration also changed; it was most pronounced in group B and statistically significant in comparison with group A. Although statistically significant difference in the results of groups B and C was found, there is a clear tendency towards faster healing of ulceration under the influence of ultrasound at 0.5 W/cm2. No statistically significant differences were observed between groups A, B and C in terms of granulation development rate and debridement of the wounds.
