Mini Systematic Review of Subthalamic Nucleus Deep Brain Stimulation as a Treatment for Gait and Dysarthria in Parkinson's Disease, A

This review investigated the efficacy of subthalamic nucleus deep brain stimulation (STN DBS) as a treatment for gait and dysarthria in patients with Parkinson's Disease. Gait and dysarthria—walking and talking—have a huge impact on a person's day-to-day functioning. Three databases were systematically searched: PubMed, CINAHL, and ComDisDome. Eight articles were found about the two subtopics. It was discovered that although STN DBS effectively treats gait abnormality in Parkinson's patients, it usually exacerbates rather than improves dysarthria. It was concluded that more research needs to be conducted on difference stimulation settings to see if STN DBS can improve gait and dysarthria.
