The Effect of Cassava Waxes Hot Bath on Pain, Pressure Pain Threshold and Hand Function Among Patients With Trigger Finger
Thailand40 participantsStarted 2025-09-01
Plain-language 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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Having a diagnosis of trigger finger by a physician or a specialized physical therapist
* Present with all of the following symptoms: pain at the base of the affected finger, triggering (catching/locking) as a primary symptom (though pain often increased with it), and a palpable or audible triggering sensation during finger flexion and extension.
* Able to understand and follow the research procedures.
Exclusion Criteria:
* Having a history of neurological conditions, such as stroke or diseases causing sensory impairment in the upper limbs.
* Having arthritis or infection in the upper limbs
* Having Rheumatoid Arthritis.
* Having a skin condition in the wrist or hand area, upper limb fractures within the last 6 months, or those affecting movement.
* Having musculoskeletal deformities of the upper limbs that impact movement.
* Having an inflammation (e.g., pain, swelling, redness, warmth) in the wrist and fingers
* Having a history of upper limb surgery, an allergy to cassava starch/flour.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
