A Brain Network Study on the Treatment of Upper Limb Motor Dysfunction in Stroke Patients Using Scalp Acupuncture Combined With rTMS

Transcranial magnetic stimulation applied a figure-8 coil to the premotor area at 80%-100% of the healthy-side MEP threshold. Treatment lasted 20 min in two phases: weeks 1-2 on the ipsilateral M1 (1Hz, 10s on/5s off), and weeks 3-4 on the contralateral M1 (10Hz, 3s on/12s off). Treat once a day, 5 days a week, for a total of 4 weeks.

Scalp acupuncture selected bilateral upper-limb cortical MEP points (2 points total). The healthy-side hot spot was identified first; if the affected side had no MEP, its mirror point was used. Needles were inserted from point A (affected) to B (healthy) and beyond along the AB line. After insertion, needles were rotated for 2-3 min, manipulated every 10 min, and retained for 30 min. Treat once a day, 5 days a week, for a total of 4 weeks.

Conventional drug therapy included secondary stroke prevention, neurotrophy, and improved cerebral circulation. Routine rehabilitation involved exercise, occupational, and physical therapies, with a total daily treatment time of 90 minutes.
