Individuals with Parkinson Disease (PD) often present with hypokinetic dysarthria which can impact intelligibility, ability to communicate with friends and family, and participation in socialization. Research has shown that PD may also impact how patients perceive themselves as communicators with specific negative impact on their sense of control, confidence, getting their message across, sense of adequacy, and independence. These changes in communication can lead to withdrawal and social isolation. Voice and speech deficits are frequently treated with Lee Silverman Voice Treatment (LSVT), an intensive 4-week program of voice therapy, which is regarded as the most well-researched, efficacious treatment for these symptoms. Although numerous studies have been published reporting acoustic and perceptual findings, none have assessed the impact of treatment on how patients perceive themselves. This is the first study to address changes in self-perception after LSVT in patients with PD.
