Boosting Arm Strength After Stroke with New Brain‑Tech and Digital Games

Stroke can leave many people stuck with weak arms, even after months of therapy. A new trial is testing whether a precise brain‑stimulation method called high‑definition transcranial direct current stimulation (HD‑tDCS) can make a real difference when paired with computer‑based arm exercises. The research is set up as a double‑blind, placebo‑controlled study to ensure the results are trustworthy. Participants will receive either real HD‑tDCS or a sham version that feels the same but delivers no current, while all of them engage in structured digital rehab sessions.Researchers will track changes in arm movement and safety over time, hoping to confirm that this combo can safely boost recovery. If the findings are positive, HD‑tDCS could become a standard add‑on to stroke rehab programs, offering patients a clearer path back to everyday tasks.
