Scalp Acupuncture for Acute Ischemic Stroke: A Meta-Analysis of Randomized Controlled Trials

Abstract EN

Scalp acupuncture (SA) is a commonly used therapeutic approach for stroke throughout China and elsewhere in the world.

The objective of this study was to assess clinical efficacy and safety of SA for acute ischemic stroke.

A systematical literature search of 6 databases was conducted to identify randomized controlled trials (RCTs) of SA for acute ischemic stroke compared with western conventional medicines (WCMs).

All statistical analyses were performed by the Rev Man Version 5.0.

Eight studies with 538 participants were included in the studies.

The studies were deemed to have an unclear risk of bias based on the Cochrane Back Review Group.

Compared with the WCM, 6 RCTs showed significant effects of SA for improving neurological deficit scores (P<0.01); 4 RCTs showed significant effects of SA for favoring the clinical effective rate (P<0.01) However, the adverse events have not been documented.

In conclusion, SA appears to be able to improve neurological deficit score and the clinical effective rate when compared with WCM, though the beneficial effect from SA is possibly overvalued because of generally low methodology of the included trials.

No evidence is available for adverse effects.

Rigorous well-designed clinical trials are needed.
