Summary

The goal of this clinical trial is to learn if ultrasonication-mediated microbubbles dressing works to treat hand arthritis in adults. It will also learn about the safety of ultrasonication-mediated microbubbles dressing. The main questions it aims to answer are: Does ultrasonication-mediated microbubbles dressing increase the therapeutic efficacy of piroxicam gel for hand arthritis? Researchers will compare "ultrasonication-mediated microbubbles dressing + piroxicam gel " to "ultrasonication + piroxicam gel" and "piroxicam gel alone" to see if ultrasonication-mediated microbubbles dressing works to treat hand arthritis. Participants will: Take "ultrasonication-mediated microbubbles dressing (day 1,3,5) + piroxicam gel (day 2,4,6,7) ", "ultrasonication (day 1,3,5) + piroxicam gel (day 2.4.6.7)", and "piroxicam gel alone (day 1-7)" for 1 week. Visit the clinic on day 1 and day 8 for checkups and tests Keep a diary of their symptoms

Conditions

• Hand Arthritis

Interventions

Type	Name	Description
PROCEDURE	ultrasonication-mediated microbubbles dressing	The microbubble suspension is diluted with normal saline to a concentration of 2x10\^7 bubbles/mL, applied to a gauze cloth, and covered on the joint skin surface. The joint is ultrasonicated for 3 minutes using an ultrasonic implanter (KUM-2000, NEO-TEC, Taipei, Taiwan), and then piroxicam gel is applied. The parameter values for ultrasonication are duty cycle 0.5, Tempo 10, intensity 70%, and time 3 min. This treatment is performed on day 1, 3, and 5.
PROCEDURE	ultrasonication using pure gel	The joint is ultrasonicated for 3 minutes using an ultrasonic implanter (KUM-2000, NEO-TEC, Taipei, Taiwan) with pure gel, and then piroxicam gel is applied. The parameter values for ultrasonication are duty cycle 0.5, Tempo 10, intensity 70%, and time 3 min. This treatment is performed on day 1, 3, and 5.
