Electroacupuncture (EA) effectively improves cognitive and motor functions in patients with post-stroke cognitive impairment (PSCI). While safe, further high-quality studies are needed due to the low quality of existing research on EA for PSCI.
Area of Science:
- Neurology
- Integrative Medicine
- Rehabilitation
Background:
- Post-stroke cognitive impairment (PSCI) is a common and debilitating consequence of stroke.
- Current treatments for PSCI have limited efficacy, necessitating exploration of alternative therapeutic approaches.
- Electroacupuncture (EA) is a traditional Chinese medicine technique with potential neuroprotective and cognitive-enhancing properties.
Purpose of the Study:
- To systematically evaluate the efficacy and safety of electroacupuncture (EA) for treating post-stroke cognitive impairment (PSCI).
- To synthesize evidence from randomized clinical trials (RCTs) to determine the effectiveness of EA in improving cognitive and motor functions in PSCI patients.
Main Methods:
- A comprehensive literature search was conducted across multiple databases (CNKI, CBM, WanFang, VIP, PubMed, Cochrane Library) for RCTs published before October 2016.
- Two independent reviewers performed literature screening and data extraction.
- Meta-analyses were conducted using RevMan 5.3 software, with study quality assessed according to the Cochrane Reviewers' Handbook guidelines.
Main Results:
- Fourteen RCTs involving 896 PSCI patients were included in the meta-analysis.
- EA significantly improved scores on the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA).
- EA also demonstrated benefits in P300 latency and amplitude, Fugl-Meyer Assessment (FMA) scores, and overall clinical effective rate, though not significantly impacting the Barthel Index (BI) score.
Conclusions:
- Electroacupuncture (EA) is confirmed as an effective and safe treatment for improving cognitive and motor functions in patients with post-stroke cognitive impairment (PSCI).
- The findings suggest EA can be a valuable adjunct therapy for PSCI.
- High-quality, well-designed, multicenter RCTs are recommended to further validate these findings due to the limitations in the quality of the included studies.
