Thread-Embedding Acupuncture Versus Electroacupuncture for Mild-to-Moderate Carpal Tunnel Syndrome

Thread-Embedding Acupuncture Versus Electroacupuncture for Mild-to-Moderate Carpal Tunnel Syndrome: An Assessor-Blinded Randomized Controlled Trial

This study compared thread-embedding acupuncture with electroacupuncture for adults with mild-to-moderate carpal tunnel syndrome confirmed by electrodiagnosis. Eighty participants were randomly assigned in a 1:1 ratio to receive either thread-embedding acupuncture or electroacupuncture. Both groups also received standard care, including lifestyle modification, nocturnal wrist splinting, nerve and tendon gliding exercises, and paracetamol as needed. Thread-embedding acupuncture was administered twice over two weeks, whereas electroacupuncture was administered 10 times over the same period. Participants were assessed at baseline, week 2, and week 4. The primary outcome was the change in paresthesia intensity from baseline to week 4, measured using a 100-mm visual analog scale. Secondary outcomes included pain intensity, symptom severity, functional status, paracetamol use, and adverse events.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: Thread-Embedding Acupuncture
Participants received thread-embedding acupuncture twice over two weeks, at baseline and week 1, in addition to standard care.
Verfahren: Thread-Embedding Acupuncture
Thread-embedding acupuncture was administered twice over two weeks, at baseline and week 1. Sterile polydioxanone thread-embedding needles were inserted at PC4, PC6, PC7, PC8, LI4, LI5, LU10, LU6, HT7, and TE5. The device consisted of a sterile 31-G stainless-steel cannula with a 30-mm needle shaft and a 30-mm polydioxanone thread folded in half, corresponding to an embedded thread length of approximately 15 mm. The thread was placed within the muscle layer and left in situ after withdrawal of the needle.
Sonstiges: Standard Care
Both treatment groups received standard care throughout the four-week study period, including lifestyle modification to avoid wrist flexion and strain, nocturnal wrist splinting, daily nerve and tendon gliding exercises, and paracetamol 500 mg as needed for intolerable pain with a minimum four-hour interval between doses.
Aktiver Komparator: Electroacupuncture
Participants received electroacupuncture once daily, five times per week for two weeks, for a total of 10 sessions, in addition to standard care.
Sonstiges: Standard Care
Both treatment groups received standard care throughout the four-week study period, including lifestyle modification to avoid wrist flexion and strain, nocturnal wrist splinting, daily nerve and tendon gliding exercises, and paracetamol 500 mg as needed for intolerable pain with a minimum four-hour interval between doses.
Verfahren: Electroacupuncture
Electroacupuncture was administered once daily, five times per week for two weeks, for a total of 10 sessions. Sterile disposable needles were inserted at PC4, PC6, PC7, PC8, LI4, LI5, LU10, LU6, HT7, and TE5. Continuous biphasic rectangular pulses with alternating frequencies of 2/100 Hz every 3 seconds and a pulse width of 0.2 ms were delivered for 20 minutes. Stimulation intensity was adjusted within 2-5 mA according to participant tolerance.

Change From Baseline in Paresthesia Visual Analog Scale Score at Week 4
Zeitfenster: Baseline to Week 4
Paresthesia intensity was measured using a self-reported 100-mm visual analog scale ranging from 0 mm, representing no symptom, to 100 mm, representing the worst imaginable symptom. The outcome was the change in paresthesia-VAS score from baseline to week 4.

Change From Baseline in Paresthesia Visual Analog Scale Score at Week 2
Zeitfenster: Baseline to Week 2
Paresthesia intensity was measured using a self-reported 100-mm visual analog scale ranging from 0 mm, representing no symptom, to 100 mm, representing the worst imaginable symptom. The outcome was the change in paresthesia-VAS score from baseline to week 2.
Baseline to Week 2
Change From Baseline in Pain Visual Analog Scale Score
Zeitfenster: Baseline to Week 2 and Week 4
Pain intensity was measured using a 100-mm visual analog scale ranging from 0 mm, representing no pain, to 100 mm, representing the worst imaginable pain. The outcome was the change in pain-VAS score from baseline.
Baseline to Week 2 and Week 4
Change From Baseline in Boston Carpal Tunnel Questionnaire Scores
Zeitfenster: Baseline to Week 2 and Week 4
The Boston Carpal Tunnel Questionnaire consists of the Symptom Severity Scale (SSS) and Functional Status Scale (FSS). The SSS includes 11 items scored from 1 to 5, with a total score ranging from 11 to 55. The FSS includes 8 items scored from 1 to 5, with a total score ranging from 8 to 40. The overall BCTQ score was calculated as the sum of the SSS and FSS scores, ranging from 19 to 95. Higher scores indicate greater symptom severity and functional impairment.
Baseline to Week 2 and Week 4
Weekly Paracetamol Consumption
Zeitfenster: Weekly during the 4-week study period
Rescue paracetamol use was recorded as the number of 500-mg tablets consumed per week.
Weekly during the 4-week study period
Adverse Events
Zeitfenster: From baseline through Week 4
Adverse events occurring during the study were monitored and recorded, including events such as ecchymosis and localized pain associated with the acupuncture procedures.
