Summary

Objective: This study aimed to evaluate the efficacy of cassava wax hand immersion combined with ultrasound therapy on pain severity, pain threshold, finger locking frequency, and hand functional ability in patients with trigger finger. We assessed immediate, short-term, and long-term treatment outcomes. Methods: This was a randomized controlled trial. Thirty-eight eligible volunteers were randomly assigned to two groups. The experimental group received ultrasound therapy combined with cassava wax hand immersion, while the control group received ultrasound therapy alone. Treatments were administered three times per week for four weeks.

Interventions

Type	Name	Description
DEVICE	ultrasound therapy and cassava wax hot immersion	participants sat in a comfortable position with their hand placed on a pillow or cushion. Ultrasound gel was applied to the base of the painful finger, and ultrasound therapy was performed for 5 minutes at a frequency of 3 MHz and an intensity of 0.5-1 W/cm. Afterward, the hand was cleaned and immersed in cassava wax heated to 125°F (51.7°C). The affected hand was dipped into the wax for 3 seconds, then removed. This process was repeated for 10 cycles. The hand was then wrapped in a plastic bag and a towel for 15 minutes before the wax was removed and peeled off.
