Official title: The Effect of Lee Silverman Voice Therapy-LOUD (LVST-LOUD) Therapy Method on Voice and Speech Skills and Examination of Therapy Experiences in Turkish-Speaking Individuals With Parkinson's Disease
Run by Atlas University · NCT07730073 · Data updated 2026-11-12
A Turkish-speaking group with Parkinson’s will try the LSVT-LOUD voice therapy to see if it improves loudness and speech quality.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are native Turkish speakers with idiopathic PD, Hoehn and Yahr stage I–III, aged 40–80, with reported voice/speech impairment and adequate cognitive function (MMSE ≥ 24).
✕Probably not a fit
Individuals with significant cognitive impairment, other major neurological conditions, or uncorrected hearing loss may receive less or no benefit.

What this trial studies
This trial tests the LSVT-LOUD protocol in Turkish-speaking adults with idiopathic Parkinson’s disease. Participants undergo intensive, four-week, 60-minute therapy sessions four times per week, focusing on high-effort vocal production and progressive tasks from words to conversation. Outcomes include objective measures of loudness and speech intelligibility as well as participant-reported experiences. The study adapts the standard LSVT-LOUD method to Turkish language and cultural context. It aims to inform clinical use and broader adaptation of this therapy for Turkish speakers with PD.
Why it matters
Potential benefit: If successful, participants may experience clearer speech and improved communication in daily life.
How similar studies have gone: Prior LSVT-LOUD studies show benefit in improving voice and speech in PD, though language adaptations are less common; results are supportive but context-dependent.

Show full inclusion / exclusion criteria
Inclusion Criteria: Diagnosis: Patients with a confirmed diagnosis of Idiopathic Parkinson's Disease (Hoehn and Yahr stages I-III). Age: Individuals aged 40-80 years. Language: Native Turkish speakers. Cognitive Status: Sufficient cognitive function to participate in therapy (e.g., Mini-Mental State Examination (MMSE) score ≥ 24). Communication: Presence of voice or speech impairment (e.g., hypophonia, reduced intelligibility) as confirmed by a speech-language pathologist. Stability: Stable medication regimen for at least 1 month prior to the study initiation. Exclusion Criteria: Neurological Comorbidities: Presence of other significant neurological disorders (e.g., stroke, traumatic brain injury, multiple sclerosis) or active voice disorders (e.g., vocal cord nodules, laryngeal cancer). Hearing Impairment: Uncorrected hearing loss that would interfere with speech assessment or therapy. Cognitive Impairment: Diagnosis of dementia or severe cognitive impairment that prevents participation in the intensive LSVT-LOUD protocol. Recent Surgery: History of laryngeal surgery or deep brain stimulation (DBS) within the last 6 months. Therapy History: Previous experience with LSVT-LOUD or intensive speech therapy within the past year.
