[Communication disorders marked with hypophonia. Indication and speech therapy through the LSVT method]

Area of Science:

• Neurology
• Speech-Language Pathology

Background:

• The Lee Silverman Voice Treatment (LSVT) is a widely adopted speech therapy method.
• LSVT is primarily indicated for communication disorders associated with Parkinson's disease.
• Neuro-radiological studies increasingly support the efficacy of LSVT.

Observation:

• This study evaluated LSVT for both Parkinson and non-Parkinson hypophonia.
• Patient-reported outcomes using the Vocal Handicap Index (VHI) demonstrated significant communication improvements.
• Observed improvements in communication were dramatic and systematic, despite initial reluctance.

Findings:

• LSVT administration resulted in a systematic and dramatic improvement in patient communication.
• Vocal Handicap Index scores showed significant positive changes, indicating reduced vocal handicap.
• The stability and peripheral effects of LSVT were carefully monitored.

Implications:

• LSVT is a pertinent therapeutic approach for hypophonia in Parkinson's disease.
• The study highlights the need for careful administration and consideration of precautions.
• Findings support the broader application of LSVT for non-Parkinsonian hypophonia.
