Primary outcomePrimary: Pain on the Numeric Rating Scale (NRS) Change From Baseline to Study Conclusion — -1.96; -0.85 units on a scale
Summary
The purpose of this study is to measure the effectiveness of a wearable therapeutic ultrasound device in patients with stage I and stage II knee osteoarthritis. The ability of the device to reduce pain, increase mobility, increase range of motion and muscle strength of the affected leg, and improve quality of life in patients with knee osteoarthritis will be evaluated.
