The Effect of Cassava Waxes Hot Bath on Pain, Pressure Pain Threshold and Hand Function Among Patients With Trigger Finger

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.
