This study retrospectively analyzed the therapeutic consequences of combining electroacupuncture and transcranial direct current stimulation (tDCS) with speech and language therapy (SLT) in subacute post-stroke aphasia (PSA) patients. The results showed significant improvements in spontaneous conversation and naming ability in the acupuncture group, as well as improvement in word retrieval. Future clinical trials are needed to further validate the effectiveness of this treatment approach.
Objective: Emerging evidence shows the effectiveness of speech and language therapy (SLT); however, precise therapeutic parameters remain unclear. Evidence for the use of adjunctive transcranial direct current stimulation (tDCS) to treat post-stroke aphasia (PSA) is promising; however, the utility of combining tDCS and electroacupuncture (EA) has not yet been analyzed. This study assessed the therapeutic consequences of EA and tDCS coupled with SLT in subacute PSA patients who were also undergoing hyperbaric oxygen therapy (HBOT). Methods: A retrospective analysis was conducted on subacute (< 6 months) PSA patients who were divided into three groups: patients who received EA plus tDCS (acupuncture group), patients who underwent tDCS (tDCS group), and patients who experienced conventional therapy (HBOT + SLT). All subjects underwent 21 days of treatment and also received conventional treatment. The aphasia battery of Chinese (ABC) was used to score pre- and post-intervention status. Results: The analysis comprised 238 patients. Cerebral infarction was the most frequent stroke type (137 [57.6%]), while motor (66 [27.7%]) and global aphasia (60 [25.2%]) were the most common types of aphasia. After 21 days of intervention, the ABC scores of all patients were improved. The acupuncture group had the highest ABC scores, but only repetition, naming, and spontaneous speech were statistically improved (P < 0.01). Post-hoc tests revealed significant improvement in word retrieval in the acupuncture and tDCS groups (P < 0.01, P = 0.037), while the acupuncture group had additional significant improvement in spontaneous conversation (P < 0.01). Conclusion: Combining acupuncture and tDCS as an adjuvant therapy for subacute PSA led to significant spontaneous speech and word retrieval improvements. Future prospective, multi-ethnic, multi-center trials are warranted. Please cite this article as: Msigwa SS, Li Y, Cheng XL, Cao F.
