Abstract

This article investigates how improvements in motor performance through actual practice affect corticospinal tract excitability during motor imagery (MI) of the same movements. In a study with 21 healthy right-handed adults, participants practiced finger abduction tasks at varying force levels (20%, 40%, and 60% of maximum voluntary contraction), with assessments conducted before and after extensive practice sessions. Results showed that as motor performance improved, corticospinal excitability measured by motor-evoked potentials during MI decreased, while the vividness of MI increased, suggesting enhanced neural efficiency and reduced redundant activity. These findings indicate that motor learning through physical practice is reflected in MI, supporting the potential utility of MI in rehabilitation and motor skill acquisition.
