Deep brain stimulation (DBS) is a relatively common intervention for individuals with Parkinson's Disease, used to alleviate tremor especially when medication is no longer effective on its own (Niketeghad, Nedrud, Hanrahan & Mahoor, 2014). Insertion of electrodes can occur at multiple cortical sites, with the subthalamic nucleus being one of the most commonly used in clinical practice as well as one of the most researched locations. While providing remarkable results in the management of tremor, STN-DBS does not restore prior neurophysiological function and has been associated with unwanted side effects involving speech and swallowing which impact overall quality of life (Guehl et al., 2006; Hammer et al., 2011; Klostermann et al., 2008; Ostergaard & Sunde, 2005). To ameliorate these undesirable side effects, researchers have manipulated different DBS parameter settings including: frequency, amplitude/voltage, and electrical current customization.
