Intensive voice treatment (LSVT®) for patients with Parkinson's disease: a 2 year follow up
The findings provide evidence for the efficacy of the LSVT® as well as the long term maintenance of these effects in the treatment of voice and speech disorders in patients with idiopathic Parkinson's disease. Expand
Formant centralization ratio: a proposal for a new acoustic measure of dysarthric speech.
The present findings indicate that the FCR is a sensitive, valid, and reliable acoustic metric for distinguishing dysarthric from unimpaired speech and for monitoring treatment effects, probably because of reduced sensitivity to interspeaker variability and enhanced sensitivity to vowel centralization.

Changes in vocal loudness following intensive voice treatment (LSVT®) in individuals with Parkinson's disease: A comparison with untreated patients and normal age‐matched controls
Differences in SPL between the treated and untreated patients at post‐treatment and follow‐up were statistically significant for all voice and speech tasks, and provide additional support for the efficacy of the LSVT®. Expand
Effects of intensive voice treatment (the Lee Silverman Voice Treatment [LSVT]) on vowel articulation in dysarthric individuals with idiopathic Parkinson disease: acoustic and perceptual findings.
The results of this study add further support to the generalized therapeutic impact of intensive voice treatment on orofacial functions (speech, swallowing, facial expression) and respiratory and laryngeal functions in individuals with PD. Expand
Speech treatment for Parkinson's disease.
The authors review the literature on the characteristics and features of speech and voice disorders in people with PD, the types of treatment techniques available, including medical, surgical, and behavioral therapies, and provide recommendations for the current efficacy of treatment interventions and directions of future research.

The science and practice of LSVT/LOUD: neural plasticity-principled approach to treating individuals with Parkinson disease and other neurological disorders.
The potential of a single target in treatment to encourage cross-system improvements across seemingly diverse motor systems is elucidated and key elements in mode of delivery of treatment that are consistent with principles of neural plasticity are discussed. Expand
Current Perspectives on the Lee Silverman Voice Treatment (LSVT) for Individuals With Idiopathic Parkinson Disease
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 forExpand

It is suggested that HKD is a highly complex and variable phenomenon including multiple factors, such as scaling and maintaining movement amplitude and effort; preplanning and initiation of movements; internal cueing; sensory and temporal processing; automaticity; emotive vocalization; and attention to action (vocal vigilance).

LSVT LOUD and LSVT BIG: Behavioral Treatment Programs for Speech and Body Movement in Parkinson Disease
An integrative discussion of the LSVT Programs including the rationale for their fundamentals, a summary of efficacy data, and a discussion of limitations and future directions for research are provided. Expand
Articulatory changes in muscle tension dysphonia: evidence of vowel space expansion following manual circumlaryngeal therapy.
The reader will be able to understand the basis for viewing muscle tension dysphonia as a disorder not solely confined to the larynx, and describe possible articulatory changes associated with successful treatment of muscle tension Dysphonia, by means of additional vowel acoustic measures. Expand
