Study Arms:
- Experimental: SAM ultrasound and diclofenac patch (Type: EXPERIMENTAL): Patients receive treatment from the SAM Ultrasonic Diathermy Device for 4 hours every day for 7 days combined with 1% diclofenac patch. The SAM device emits continuous ultrasound at 3 megahertz (MHz) frequency and 0.132 watts/cm2 intensity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
