Little is known about the neural correlates underlying the control of highly coordinated bilateral lower limb movements. In this paper we present an fMRI paradigm consisting of balancing a virtual ball rolling on a virtual bar. The subject can control the position of the bar by its lower limbs using the MR-compatible stepper MARCOS. Concurrent visual and force feedback about the state of the physical model of ball and bar is presented to the subject during task execution. In a pilot study, significant cerebellar and parieto-frontal activity was found, according to physiological expectations, demonstrating the feasibility of the experimental set-up. Further experiments will help to better understand human motor control as well as to develop more targeted rehabilitation strategies for patients with neurological movement disorders of the lower limbs.
