A new analysis of 56 studies involving 3,383 stroke survivors suggests that acupuncture may help improve arm function after a stroke. The review looked at several types of acupuncture, including manual, warm, scalp, fire, and electro-acupuncture. Researchers found that people who received acupuncture scored higher on the Fugl-Meyer Assessment, a test of motor recovery, compared to those who did not. The improvement was modest but statistically significant.
The analysis included studies with varying designs and quality, and the certainty of the evidence was assessed using GRADE methods. While the results are promising, the review has limitations. Many of the individual studies were small, and the types of acupuncture and comparison treatments varied widely. This makes it hard to draw firm conclusions about which type works best or how much benefit to expect.
Adverse events related to acupuncture were reported, but serious side effects were not mentioned in the summary. As with any treatment, it is important to discuss options with a healthcare provider. For now, acupuncture appears to be a safe complementary approach that may offer some benefit for arm recovery after stroke, but more high-quality research is needed to confirm these findings.
