Background: Ultrasound therapy can be utilized to manage chronic wounds including venous leg ulcers (VLUs). Objectives: A randomized controlled clinical study was conducted to compare the effectiveness of standard treatment and standard treatment plus either high frequency ultrasound (HFU) or noncontact low-frequency ultrasound (NCLFU) on VLU outcomes. Results: Initial wound measurements were 9.60 cm 2 (SD 5.54) 9.86 cm2 (SD 3.95) and 10.01 cm 2 (SD 4.58) for the standard treatment HFU and NCLFU groups respectively. After 4 months measurements were reduced to 4.28 cm 2 (SD 2.80) 3.23 cm 2 (SD 2.39) and 2.72 cm 2 (SD 2.16) for the standard treatment HFU and NCLFU groups respectively which was statistically significant (P = 0.04). All wounds were healed after an average of 8.50 (SD 2.17) 6.86 (SD 2.04) and 6.65 (SD 1.59) months in the standard treatment, HFU and NCLFU groups respectively (P = 0.001). Differences in the amount of edema and pain rating scores were also significant at the 4th month follow up visit (P = 0.05). Conclusions: Outcomes of both methods of ultrasound therapy were better than standard care alone, and some differences between the two ultrasound therapy groups were observed, but they were not statistically significant.
