ACURES: Acoustic and Respiratory Parameters for Dysarthria Assessment

Evaluating Dysarthria Through Acoustic and Respiratory Parameters: A Clinical Protocol

Sponsor

University of Salamanca

Enrollment

100 participants

Start Date

Oct 15, 2025

Study Type

OBSERVATIONAL

Conditions

Acquired Brain Injury Dysarthria

Summary

The goal of this observational study is to describe speech and breathing patterns in adults after acquired brain injury (ABI) and understand how these patterns relate to the presence, severity, and type of dysarthria. The main questions it aims to answer are: * What changes in voice and breathing are observed in adults with dysarthria after ABI? * Can combining acoustic, respiratory, and clinical assessments help identify dysarthria severity and subtype? Participants will: * Have their speech recorded to measure voice and articulation features, such as pitch, clarity, and the ability to sustain sounds. * Perform breathing tests using a spirometer to assess lung function. * Complete the Frenchay Dysarthria Assessment-2 (FDA-2), adapted to Spanish, to classify dysarthria type and severity. About 97 to 101 participants will take part. The results will help speech therapists better detect, evaluate, and treat dysarthria in adults after brain injury.

Eligibility

Min Age: 18 Years

Inclusion Criteria7

Adults aged 18 years or older at the time of enrollment.
Diagnosed with acquired brain injury (ABI), including:
Stroke
Traumatic brain injury (TBI)
Brain tumor
Ability to provide written informed consent (or via a legally authorized representative if necessary).
Cognitive function preserved, defined as a Mini-Mental State Examination (MMSE) score ≥ 24.

Exclusion Criteria7

History of chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD) or asthma.
History of hearing impairments that could affect speech evaluation.
Presence of additional neurological or neurodegenerative disorders other than the acquired brain injury.
History of voice disorders or dysphonia prior to the acquired brain injury.
Presence of persistent pharyngeal symptoms, such as mucus, secretions, or foreign body sensation, which may interfere with speech assessment.
Participants unable to comply with the assessment protocol or complete the required sessions.
Presence of apahasia that prevents participation in speech tasks, such as reading, repetition, or spontaneous speech priduction.
