Demonstration of two 30-second trials of finger tracking from the less affected hand in a representative participant from the no motor-evoked potential group (no-MEP, a) and the MEP group (b). The blue line represents the target waveform with the participant's corresponding tracking responses denoted by the red line. Accuracy Index (AI) scores were normalized to each participant's maximum flexion (Max Flex.) and extension (Max Ext.) active range of motion at the metacarpophalangeal joint of the affected (not shown) and less affected index fingers. Higher positive AI scores (maximum AI score = 100%) indicate better tracking performance.
