Evaluating Dysarthria Through Acoustic and Respiratory Parameters: A Clinical Protocol
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.
• 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.
