A SICIAPB was tested from 3 participants receiving DS (male, aged 69 years, SICIAPB at Baseline: 98.7% control MEP, SICIAPB at Post: 63.1% control MEP), SS (female, aged 63 years, SICIAPB at Baseline: 88.7% control MEP, SICIAPB at Post: 76.4% control MEP) and NS (male, aged 74 years, SICIAPB at Baseline: 93.1% control MEP, SICIAPB at Post: 107% control MEP) protocols. B After 10-session interventions, SS group induced an improvement in SICIAPB compared with sham, whereas DS group promoted greater SICIAPB recovery than both SS and NS groups. C Relationship between changes in SICIAPB and gait speed in DS group. D Relationship between changes in SICIAPB and stride length in DS group. Abbreviations: SICI short-interval intracortical inhibition, APB abductor pollicis brevis, MEP motor evoked potentials, DS dual-site, SS single-site, NS no-site, Post 1 day postintervention; FDR false discovery rate. *p < 0.05, **p < 0.01, ***p < 0.001.
