About

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.

Full description

This study was designed as a randomized, open-label, parallel-group trial conducted at the Traditional Medicine Hospital in Dak Lak, Vietnam. It received ethical approval from the Biomedical Research Ethic Committee at the University of Medicine and Pharmacy at Ho Chi Minh City (Approval No. 739/HĐĐĐ-ĐHYD, dated December 14, 2021). The interventions were delivered by certified traditional medicine practitioners following strict protocols (STRICTA 2010).

Catgut Thread Embedding (TE group): Participants received thread embedding at the EX-HN21 acupoint.

Electroacupuncture (EA group): Participants underwent daily 20-minute sessions in 30 days.

Language function was assessed using standardized tools, and data were analyzed with R. Statistical tests (chi-square, t-tests) compared baseline characteristics and outcomes, with a significance level of p < 0.05.
