An adequate evaluation of language and speech during an awake brain surgery has functional implications that can affect the quality of life of oncologic patients. In Portugal, there is a lack of standardised and validated tools to conduct this type of evaluation. To address this need, this study seeks to adapt the phonological and articulatory tasks of the Dutch Linguistic Intraoperative Protocol (DuLIP) into European Portuguese, while also contributing toward its standardisation. To achieve this, the support of a multidisciplinary team was required. After adapting the stimuli, a normative study was conducted in a group of 144 healthy individuals. The impact that the age, gender and years of schooling of these individuals had on the adapted tasks was measured. Calculations were made to examine if attention and memorisation levels correlate with the phonological odd word out task. Only tasks with a hit rate higher than 90% were included in the final version of the tool. The years of schooling had a significant influence in the phonological fluency task (p<.001) and the gender also had a significant impact in the word repetition task (p=.002). This is an innovative study in Portugal because it is one of the first contributions to the standardisation of a tool that can be used during an awake brain surgery. However, additional steps are required before this tool can be used in the clinical practice.
