Exercise effect on balance performance on a challenging beam in the chronic MPD. Two and 10 weeks after MPTP/probenecid treatment, the chronic MPD group of mice had significantly more limb slips than the controls while traversing the challenging beam (*P = 0.041 and *P = 0.013, respectively). The chronic MPD, when continuously exercised for 10 weeks after MPTP/probenecid treatment, had significantly less foot slips on the challenging beam than the sedentary chronic MPD (**P = 0.01).
