The effect of intensive voice therapy (Lee Silverman Voice Treatment, LSVT) on vocal tremor features of Parkinson speakers is presented. Vocal tremor is the low-frequency variation of the vocal frequency. Its features differ for Parkinson and normophonic speakers. Here, vocal tremor features have been estimated for a corpus of speakers with Parkinson’s disease, recorded before and after intensi...

BACKGROUND Parkinson's disease is a common movement disorder affecting approximately 127,000 people in the UK, with an estimated two thirds having speech-related problems. Currently there is no preferred approach to speech and language therapy within the NHS and there is little evidence for the effectiveness of standard NHS therapy or Lee Silverman voice treatment. This trial aims to investigat...

Physiotherapy is widely used in Parkinson's disease (PD), but there are few controlled studies comparing active interventions. Recently, a technique named "LSVT®BIG" has been introduced. LSVT®BIG is derived from the Lee Silverman Voice Treatment and focuses on intensive exercising of high-amplitude movements. In the present comparative study, 60 patients with mild to moderate PD were randomly a...

Reduced speech intelligibility has been observed in Parkinson’s disease (PD), ataxic dysarthria, multiple sclerosis (MS) and in individuals who have suffered a cerebral vascular accident (CVA). Data support the effectiveness of the Lee Silverman Voice Treatment (LSVT) on the improvement of vocal function and speech intelligibility in PD. Today, only a small percentage of patients with chronic n...

Design: A pre-test–post-test design was completed in order to determine if an extended Lee Silverman Voice Treatment (LSVT) program (LSVT-X) results in significant increases to vocal sound pressure level (SPL) and significant functional improvement in communication. LSVT-X results for vocal SPL and a perceptual rating of speech were then compared with the results of a previous study examining t...

Objectives: In the early stages, most Parkinson’s patients display some degrees of voice and speech disorders. Speech disorders can negatively affect individuals’ social interactions life; thus, treatment plans for in stages might be further beneficial than late stages. Therefore, we aimed to investigate effects an intervention on Persian-speaking with mild Disease (PD). The was Lee Silverman V...

The prevalence of disordered communication is particularly high in individuals diagnosed with idiopathic Parkinson disease (IPD). At least 89% of these individuals have disordered speech and voice but only 3-4% received speech treatment. LSVT (Lee Silverman Voice Treatment) is a speech and voice treatment for individuals with Parkinson disease. It is the only speech treatment with Level one sho...

Successful treatment of speech disorders in individuals with progressive neuro logical diseases can be challenging. Hillman, Gress, Haugraf, Walsh, and Bunting (1990) stated that “voice treatment for disorders that are degenerative is controversial since there is no expectation for recovery of function or that any improvement secondary to speech language pathology intervention will be maintaine...
