Stimulation-related complications include muscle pulling, paresthesias, eyelid apraxia, hypophonia, worsened postural instability, visual disturbances, mood changes, and pain. Hemiballismus can occur with higher stimulation voltages, but it is controlled successfully by reducing the voltage, decreasing the dose of levodopa, or both. In general, all stimulation-related complications can be addressed with electrical parameter changes.
