Official title
The Effect of Cassava Waxes Hot Bath on Pain, Pressure Pain Threshold and Hand Function Among Patient With Trigger Finger: Single-Blind Randomized Controlled Trial Study
Overview
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
- 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 - Device ultrasound therapy
1\. ultrasound therapy 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.
Primary outcome measures
- Visual Analog Scale (VAS) [Time frame: - Time 1: Baseline or Day 1 - Time 2:After treatment, the first time of immediate effect - Time 3: After treatments in 4 weeks - Time 4: 1 month after finishing treatments in 4 weeks.]
- Pressure pain threshold [Time frame: - Time 1: Baseline or Day 1 - Time 2:After treatment, the first time of immediate effect - Time 3: After treatments in 4 weeks - Time 4: 1 month after finishing treatments in 4 weeks.]
- Pain frequency [Time frame: - Time 1: Baseline or Day 1 - Time 2: After treatments in 4 weeks - Time 3: 1 month after finishing treatments in 4 weeks.]
- Disability of the arm, shoulder and hand [Time frame: - Time 1: Baseline or Day 1 - Time 2: After treatments in 4 weeks - Time 3: 1 month after finishing treatments in 4 weeks.]
Eligibility criteria
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.
