A secondary head-to-head comparison of low-intensity focused ultrasound and repetitive transcranial magnetic stimulation for motor recovery after stroke

Resting-state fALFF and ΔfALFF following the 2-week intervention.
(A) Prefrontal fALFF increased from baseline to post-intervention in the LIFU group (paired t-test, p = 0.002, Cohen’s d = 0.54). (B) No statistically significant change in prefrontal fALFF was observed in the rTMS group (paired t-test, p = 0.067, Cohen’s d = −0.41). (C) The ΔfALFF in motor-related regions differed between groups, with greater values observed in the LIFU group compared with the rTMS group (independent-samples t-test, t = 2.44, p = 0.019, Cohen’s d = 0.74). Each circle represents an individual participant. Data are presented as mean ± SD. *p < 0.05 indicates a statistically significant within-group or between-group comparison.
