Escala Barcelona para la apraxia bucofonatoria: instrumento de evaluación cuantitativo

Abstract

IntroductionCurrently there is no tool to quantify buccophonatory apraxia to stratify, compare and monitor patients longitudinally in an objective manner. Our aim in this study is to create a quantitative scale for buccophonatory apraxia and evaluate it in patients with the non-fluent/grammatical variant of Primary Progressive Aphasia (nfvPPA) and other neurodegenerative diseases that occur with speech and/or language problems. MethodsThe scale was designed based on useful elements in the assessment of buccophonatory apraxia and the total was quantified in seconds. The scale was administered to 64 participants with diagnoses of: nfvPPA, semantic variant of Primary Progressive Aphasia (svPPA), logopenic variant of Primary Progressive Aphasia (lvPPA), Huntington's disease, Parkinson's disease, as well as a group of healthy controls. ResultsPatients showed a significantly higher score compared to controls. The group nfvPPA had the highest mean score on the scale (429seconds±278). The scale was useful to differentiate vnfPPA from svPPA and Parkinson's disease (area under curve [AUC] of 0.956 and 0.989 respectively), but less to differentiate it from Huntington's disease (AUC=0.67) and lvPPA. There was a statistically significant relationship between total score and disease severity in nfvPPA (p<0.029). ConclusionsThe Barcelona scale for buccophonatory apraxia could be useful to quantitatively evaluate buccophonatory apraxia in different neurodegenerative diseases, and compare patients, especially in nfvPPA.
