PMID 41834818WHAT IT FOUND
Patients with subacute stroke who received low-frequency acupoint electrical stimulation showed improved motor function and daily living scores.
Brain scans revealed increased activity in the right motor network and decreased activity in the left cerebellum. Changes in the right motor area correlated with better motor recovery.
Key findings
01Patients showed significantly higher Fugl-Meyer Assessment and Modified Barthel Index scores, and lower National Institute of Health Stroke Scale scores after three weeks of treatment.
02After intervention, brain activity synchrony increased in right sensorimotor network regions and decreased in the left cerebellum and left angular gyrus.
03Changes in brain activity in the right precentral gyrus were positively correlated with improvements in motor function scores.

What it does not show
The study is a preliminary exploratory investigation with a small sample size (28 patients analyzed). There was no control group of patients receiving standard care or sham stimulation; patients were only compared to healthy controls at baseline and to themselves before and after treatment. The study focused exclusively on patients with right basal ganglia strokes, limiting generalizability to other stroke locations. The design cannot determine if the observed brain changes and clinical improvements were caused by the electrical stimulation, natural recovery, or other concurrent factors. Standardized emotional assessment tools were not used, so changes in the parahippocampal gyrus could not be linked to emotional status.
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 conclude that low-frequency acupoint electrical stimulation is an effective treatment for poststroke motor dysfunction. This was a small pilot study with no patient control group, so it is impossible to separate the effect of the stimulation from natural recovery or other concurrent treatments.
