Is cerebellar anodal transcranial direct current stimulation an appropriate locomotor intervention for people with multiple sclerosis?

The present article demonstrates split-belt treadmill training, but not cerebellar transcranial direct current stimulation (tDCS), reduces fall risk for people with multiple sclerosis. Concerns regarding the implementation of the split-belt paradigm, coupled with insensitive outcome measures and a nonoptimal neural target for tDCS may have contributed to the limited gait improvements observed. A more fitting stimulation may be to target nervous system structures in the periphery to improve sensorimotor transduction and elicit more accurate proprioception.
