SAM Ultrasound Device and Diclofenac Patch
Placebo SAM Ultrasound Device and Diclofenac Patch
Over the Counter Arthritis Pain Gel
Patients receive treatment from the wired SAM Ultrasonic Diathermy Device for 4 hours at least 5 days a week for 8 weeks combined with 2.5% diclofenac patch. The SAM device emits continuous ultrasound at 3 megahertz (MHz) frequency and 0.132 watts/cm2 intensity.
Patients receive placebo treatment from the wired SAM Ultrasonic Diathermy Device for 4 hours at least 5 days a week for 8 weeks combined with 0% diclofenac patch.
Patients apply topical 1% diclofenac gel three times per day, at least 5 days per week for 8 weeks.
