Purpose <p>This study aimed to investigate whether combining motor imagery (MI) and peripheral electrical stimulation (ES) enhances motor performance more effectively than MI alone, as literature on this is lacking.</p> Methods <p>Participants executed a wrist flexion tracking task with performance measured by error areas pre-practice, immediately post-practice (Post1), and 20&#xa0;min post-practice (Post2). ES was applied at two intensities: above the motor threshold (ES-MT) and below the motor threshold but above the sensory threshold (ES-ST). In Experiment 1, 29 healthy participants were assigned to six conditions (MI + ES-MT, MI + ES-ST, MI alone, ES-MT, ES-ST, and control), completing 150 practice trials to evaluate the MI + ES effects. Experiment 2 involved 52 healthy participants across four conditions (MI + ES-ST, MI alone, motor execution, and control), extending task difficulty and reducing trials to 100 for an equivalent practice duration, further investigating MI + ES-ST.</p> Results <p>In Experiment 1, a significant interaction between practice and condition was found (<i>p</i> = 0.019). Post-hoc analysis revealed that while all practice groups showed reduced error from Pre to Post1 and Post2, only the MI and MI + ES-ST groups demonstrated significant improvements from Post1 to Post2 (all <i>p</i> &lt; 0.05). In Experiment 2, a significant interaction was also found (<i>p</i> &lt; 0.001). The MI + ES-ST condition showed a significant decrease in error from Post1 to Post2, an effect not significant in the MI condition.</p> Conclusion <p>The combination of MI and ES-ST may have a slight positive effect on motor performance.</p>
