Resting-state functional MRI (rs-fMRI) assessed baseline FCD differences between groups, with regions showing significant alterations correlated to Fugl-Meyer Assessment (FMA) scores selected as seed points. Patients were randomized to IDSA (<jats:italic>n<\/jats:italic> =\u202f35) or Sham IDSA (<jats:italic>n<\/jats:italic> =\u202f35) therapy for 4\u202fweeks. IDSA targeted the MS6 acupoint using stainless steel needles (0.3\u202f\u00d7\u202f40\u202fmm) rotated at 200\u202frpm during active limb movement, while Sham IDSA used blunt needles without skin penetration.
