Walking while talking is a commonly performed, yet cognitively demanding, multitask. Gait and extemporaneous speech each have distinct cognitive components and consequences for poor execution. Gait and speech often evidence varying levels of dual-task cost when performed concurrently, depending on the task complexity (Raffegeau et al., 2018). Parkinson’s disease (PD) is characterized by impairment in both gait and speech. Speech and language deficits in PD result from both motor and cognitive symptoms of the disease, and even mild speech impairment can have a negative effect on verbal communication (Smith & Caplan, 2018). This has implications regarding the ability of these individuals to participate in social situations and communication interactions. The purpose of this study was to investigate the effect of dual tasking on speech production in patients with PD. Participants completed several speech tasks in a single-task condition and two dual-task conditions varying in complexity. We used speech pauses to quantify the effect of dual tasking on speech.
