A Randomized Controlled Trial Comparing the Efficacy of Thread Embedding and Electroacupuncture in Speech-Language Rehabilitation in Patients With Post-Stroke Aphasia
In Brief
A clinical study evaluating Catgut Thread Embedding and Electroacupuncture for Post-stroke Aphasia. Completed, enrolled 60 participants across 1 site.
Detailed Summary
The goal of this clinical trial was to learn if thread embedding or electroacupuncture can treat language function impairment in patients with post-stroke aphasia, a condition affecting communication after a stroke. The main questions it aimed to answer were: Does thread embedding improve overall language function more effectively than electroacupuncture, as measured by the Goodglass and Kaplan Aphasia Severity Rating Scale (ASRS)? How do thread embedding and electroacupuncture compare in improving specific language skills, such as motor speech, sensory language, reading, and naming, as assessed by the Boston Diagnostic Aphasia Examination (BDAE)? Researchers compared thread embedding (TE group) to electroacupuncture (EA group) to see if thread embedding provides better or similar effects on language recovery. Participants: Underwent a 30-day intervention with language assessments at the start and end of the period. Were randomly assigned to either the thread embedding group, receiving treatment every 10 days, or the electroacupuncture group, receiving daily 20-minute sessions.

Interventions
Catgut Thread Embedding involved implanting chromic catgut size 4.0 thread, which is attached to a 23G guide needle, into subcutaneous tissue at EX-HN21 acupoint. The guide needle was removed after insertion, while the thread remained and dissolved over 10-15 days to provide continuous stimulation.
Electroacupuncture was administered using four needles (0.3 × 25 mm, diameter × length) inserted at GV-20, EX-HN21, external EX-HN12, and external EX-HN13 acupoints. Electrical stimulation was delivered via the KWD-808I Multipurpose Health Device (Changzhou Yingdi Electronic Medical Device Co., China) with parameters set at 3 Hz frequency and 0.6 ms pulse width, the intensity was adjusted according to the patient's perception. Electroacupuncture was performed daily, except on Saturdays, Sundays, and Vietnamese national holidays, over a treatment course of 30 days.
