PMID 41477077WHAT IT FOUND
Adding acupuncture to robot therapy improved daily living scores by 7 points, exceeding the clinically important threshold.
However, gains in limb motor function were only 5 points, falling short of the 6-point threshold needed to be considered clinically meaningful.
Key findings
01The combined treatment improved Modified Barthel Index scores by 7.17 points compared to robot therapy alone, which exceeds the minimum clinically important difference of 5.34 points.
02Fugl-Meyer Assessment scores improved by 4.89 points compared to robot therapy alone, but this did not meet the minimum clinically important difference of 6 points.
03The overall quality of evidence was rated as low to very low due to high heterogeneity, lack of blinding, and concerns about allocation concealment in the included trials.

What it does not show
The certainty of evidence is very low to low due to substantial heterogeneity between studies and high risk of bias. None of the included trials blinded patients, which is difficult in acupuncture studies but introduces performance bias. Allocation concealment was poorly reported or absent in most trials, raising concerns about selection bias. The included studies used varying types of acupuncture (electro, scalp, conventional) and different robotic devices (upper vs. lower limb), making it hard to determine which specific components drive the effect. Only three studies reported safety data, so the risk of adverse events is poorly characterized.
Declared interests
The investigators have no financial or nonfinancial disclosures to make in relation to this project.
The easy way to misread this
Do not interpret the statistically significant improvement in Fugl-Meyer scores as a clinically meaningful gain in motor function. The improvement was less than the 6-point threshold required to be considered a noticeable change for the patient.
