PMID 41214733WHAT IT FOUND
Adding 1Hz rTMS to standard rehab improved upper limb movement and daily self-care more than rehab alone.
Brain scans showed increased network flexibility in sensory and cognitive areas, which correlated with better arm recovery and predicted treatment success.
Key findings
01Patients receiving rTMS plus standard rehabilitation showed significantly greater improvement in upper limb motor function and daily self-care abilities compared to those receiving standard rehabilitation alone.
02rTMS treatment increased the rate at which brain networks switched between states, particularly in the sensorimotor, fronto-parietal, and default-mode networks.
03Baseline brain network switching rates in the parietal lobes could predict how much a patient's motor function would improve with rTMS.

What it does not show
The study was single-centre and had a small sample size, which may limit the generalizability of the findings. The control group did not receive sham stimulation, so the psychological effect of receiving a treatment cannot be ruled out as a contributor to the clinical improvement. The patient group was heterogeneous in terms of lesion location, disease duration, and degree of motor impairment. The analysis focused on network switching rates and did not explore other dynamic brain network parameters.
Declared interests
The authors declared no competing interests.
The easy way to misread this
Do not assume the brain network changes caused the motor improvement directly; the study shows an association and prediction, but the control group lacked sham stimulation, meaning the clinical benefit could partly be due to the extra attention or expectation of treatment rather than the magnetic pulses alone.
