(A) Representative force trajectories (on right) obtained with isometric right thumb abductions (abductor pollicis brevis muscle, ABP; on left). Force production performance was assessed by the number of attempts falling within the target force window displayed as two horizontal lines on the computer screen. Fmax: individual maximum force. (B) Schematic overview of the experimental procedure. cTBS, continuous theta-burst stimulation; MEP, motor-evoked potentials; FPP, force production performance.
