Short-Term Effectiveness of Ultrasound Therapy in Knee Osteoarthritis

Abstract: This randomized, placebo-controlled, double-blind study was designed to investigate the short-term efficacy of ultrasound therapy in 90 patients with knee osteoarthritis (OA). Patients were randomly assigned to three groups: group 1 received continuous ultrasound, group 2 received pulsed ultrasound, and group 3 received a 'sham' (placebo) ultrasound for 5 min each session. All treatments were applied once a day for 5 days a week for 2 weeks, i.e. a total treatment duration of 10 days. Compared with baseline, s… Show more

“…In our study, the use of ultrasound was effective in reducing pain and increasing performance of patients. In the study of Tascioglu, the use of pulse mode ultrasound was with high efficiency in the reduction of pain measured using VAS (21). These findings are also similar to the results and methods of our study.…”

“…It was found that the groups with pulsed US were effective to increase the range of motion and functional performance and hyaluronic acid group was more effective in functional performance, discomfort and fibromyalgia. The parameters used in these studies (13)(14)(15) Discordant results were obtained in the study of Cakir et al (16), who reported improvement in pain, physical function, stiffness and functional performance, at the continuous US (1 MHz and 1 W / cm², 12 minutes), pulsed US (1 MHz, 1 W / cm² and a working cycle 1: 4, 12 minutes) and placebo US groups, with no differences among the groups, after 10 therapy sessions. All groups performed home exercises and the authors suggest that these exercises masked the US effects.…”

“…Studies comparing pulsed and continuous ultrasound application effectiveness on pain, physical function stiffness, discomfort, range of motion (ROM), functional performance and muscle strength (FM), demonstrated that both application forms can be effective for patients with knee osteoarthritis. However, the increase in the variables analyzed was better in the group receiving the application of pulsed ultrasound (13,14).…”
