A Critical Overview of Systematic Reviews and Meta-Analyses on Acupuncture for Poststroke Insomnia

الملخص EN

Objectives.

Acupuncture has increasingly been used for insomnia relief after stroke.

We aimed to evaluate the methodological quality and summarize the evidence regarding the effectiveness of acupuncture for poststroke insomnia (PSI) from systematic reviews/meta-analyses (SRs/MAs).

Methods.

Eight databases were searched from inception through August 23, 2020.

SRs/MAs on acupuncture treatment for PSI were included.

Methodological quality assessment was performed using Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), and evidence quality assessment was performed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).

Results.

Six SRs/MAs on acupuncture treatment for PSI were included.

The AMSTAR-2 showed that the methodological quality of all included SRs/MAs was rated as critically low.

According to the evaluation results of GRADE, 38.9% (7/18) of outcomes were rated as very low-quality evidence, 22.2% (4/18) were low-quality evidence, and 8.9% (7/18) were moderate-quality evidence.

Descriptive analysis results showed that acupuncture was an effective treatment modality for PSI.

Conclusions.

All included reviews indicated that acupuncture was more effective than the control group for the treatment of PSI, but the credibility of the results is limited owing to the generally low methodological and evidence quality of the included SRs/MAs.

More high-quality evidence is needed to determine whether acupuncture is more effective than other treatments.
