• The second section (weighting performed by the respondent) is made up of 12 questions. Those participants who choose the "no" option in question 11 will go on to the next section.
• The third section (self-perception of barriers and facilitators at the time of weighting) is made up of 2 questions.
• The fourth section (learning needs) consists of a question. Within the second section, the choice of scales was made based on a previous search in the literature about those that are most used, which to date have not been translated or adapted cross-culturally into Argentine Spanish, most of them. the same It will be aimed at all those physical therapist in Argentina who are dedicated to neurorehabilitation, vestibular rehabilitation, geriatrics and gerontology.
