Figure 1

The effects of DBS on dual costs on gait speed (left) and stride length (right) for the serial 3 subtraction (above) and verbal fluency tasks (below). For visual purposes, costs are displayed as a positive number (i.e., dual task value – single-task value). Note that if these analyses were repeated after stratifying by time since surgery, the findings were essentially unchanged; for example, among the subjects who more than 12 months after surgery, there were no changes in DT costs (p > 0.463).
