Abstract

Objective: The study intended to evaluate the extracorporeal shockwave therapy (ESWT) vs ultrasound (US) for patients with osteoarthritis (OA) of the knee. Methods: A pilot randomized controlled trial (RCT) with concealed allocation, assessor blinding, and intention-to-treat analysis. The study occurred in the Physiotherapy Outpatient Department of the Regional Hospital in Zywiec, Poland. The participants were randomly assigned to an ESWT group, n=30 and a US group, n=30. The participants in both groups attended 5-week treatments. The ESWT group received 5 treatments once per week. The US group received 10 treatments twice per week. The primary outcome was physical function using Knee injury and Osteoarthritis Outcome Score (KOOS). The secondary outcome measured mobility, pressure pain threshold (PPT), and pain on visual analog scale (VAS). Results: Post-intervention, the physical function improved on the KOOS for ESWT and US with regard to pain by a mean of 14 � 10 and 7 � 9 points (p=0.003), other symptoms and function in daily living by a mean of 12 � 11 and 4 � 7 points (p<0.001), function in sport/recreation by a mean of 22 � 16 and 4 � 14 points (p<0.001), knee-related quality of life by a mean of 20 � 16 and 6 � 6 points (p<0.001), pain on VAS by a mean of 2 � 2 and 1 � 1 points (p<0.001) respectively. The statistical significant between groups differences favoring the ESWT were found.
