Treating Parkinsonian speech: development of a feedback rating scale using a case study

Area of Science:

• Neurology
• Speech-Language Pathology

Background:

• Parkinson's disease (PD) significantly impairs speech intelligibility due to reduced vocal volume and imprecise articulation.
• Current treatments like the Lee Silverman Voice Treatment (LSVT) primarily target vocal loudness, often neglecting articulation.
• Patients with PD frequently experience perceptual deficits, hindering their ability to self-monitor speech production.

Observation:

• A novel therapeutic approach is presented to address both volume and articulation deficits in PD speech.
• The method emphasizes the role of perceptual feedback in speech motor control for individuals with PD.

Findings:

• The case study details a method designed to improve both vocal loudness and articulation in a patient with Parkinson's disease.
• Focusing on perceptual aspects of speech demonstrated potential for enhancing speech production in PD.

Implications:

• This approach may offer a more comprehensive strategy for speech rehabilitation in Parkinson's disease.
• Further research could explore the broader applicability of perceptual training for PD-related communication impairments.
