Primary outcomePrimary: Change in Pain Units on a Scale (0-10) 0 Being Least, 10 Being Worst Pain From Baseline — 2.00 pain units on a scale — p=<0.001
Summary
The purpose of this study is to measure the effectiveness of Sustained Acoustic Medicine (SAM) treatment combined with diclofenac ultrasound coupling gel in patients with stage II and stage III knee osteoarthritis. The ability of the device to reduce pain, increase mobility, increase function of the affected leg, and improve quality of life in patients with knee osteoarthritis will be evaluated.
