피록시캄 겔의 음파영동이 슬관절 통증에 미치는 효과

This study was to compared the effectiveness of piroxicam gel phonophoresis with conventional ultrasound therapy in knee osteoarthritis. Eighteen patients with a means age of $55.7{\pm}5$ years were randomly assigned to phonophoresis or ultrasound groups. Continuous ultrasonic waves of 1 MHz frequency and $1\;W/cm^2\;SATA_i$ were applied for 5 minutes to the target knee joint. This study indicated their pain level by marking on a visual analog scale(VAS) at the start of treatment and at the end of 3day. Osteoarthritis VAS scores, pain on rest state, non weight bearing range of motion, 20 meters walking, and walking step by the patients were evaluated before and after therapy. Both therapeutic modalities were found to be effective and generally well tolerated after 3 therapy sessions. But piroxicam phonophoresis was not superior to conventional ultrasound in patients with knee osteoarthritis.
