Summary

Parkinson's disease often leads to soft, unclear speech that affects daily life. This trial tests whether the Lee Silverman Voice Therapy-LOUD (LSVT-LOUD) protocol, an intensive speech therapy program, can improve vocal loudness and speech clarity in Turkish-speaking individuals with Parkinson's. Over four weeks, participants will attend 16 one-on-one therapy sessions, and researchers will measure changes in voice quality and how participants feel about the therapy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Lee Silverman Voice Therapy-LOUD (LSVT-LOUD), an intensive speech therapy protocol
What this could lead to
If effective, this could provide a tailored speech therapy option for Turkish-speaking individuals with Parkinson's, improving communication and quality of life.
What could go wrong
This is a small, early-stage study with only 24 participants, so results may not apply broadly. The therapy is intensive and requires commitment, which may not suit everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
