INTRODUCTION: Humans are social beings, therefore communication and interaction with other people is characteristic to their nature and also one of fundamental human rights. However, some people come across problems in communication, or they can not accomplish communication needs in usual way, by means of speech and/or they are not understanding the language due to various reasons. Thereby disabling them from using a fundamental human right. Right to express inherent desires, needs and thoughts. Alternative and augmentative communication replaces or supports usual ways of communication and thus helps the person to express easier or to understand the language better. GOAL: Goal of this survey was to examine, determine and present the degree of information of the physiotherapists in the Republic of Croatia about alternative and augmentative communication. Also, to find out their knowledge and opinions about the topic. METODS AND RESPONDANTS: Participated in this survey was 104 participants of which 19,4% were men, while 80,6% were women. The research was carried out via an electronic anonymous survey, designed exclusively for this research in the Google Form app. The form consisted of 26 questions. After designing the form, it was published on the Facebook page called “Fizioterapeuti RH” and members of that group were kindly asked to fill it out. RESULTS: Based on the defined goals, four hypotheses were formed. With the obtained results, the first hypothesis "Physiotherapists in the Republic of Croatia most often in their work, with patients with complex communication needs, use simple methods without aid kits" was accepted. The second hypothesis, which reads "Physiotherapists in the Republic of Croatia who have completed graduate or postgraduate studies in physiotherapy, in a higher percentage answered questions that were related to professional terminology correctly in relation to physiotherapists who have completed bachelor degree or high school" was also accepted. While third hypothesis "More the 50% of participants have completed education in the field of alternative and augmentative communication." was rejected. Also, fourth hypothesis "Physiotherapists who work in private institutions in the Republic of Croatia use the alternative and augmentative communication more in their work than physiotherapists in the Republic of Croatia who work in state institutions." was dismissed. CONCLUSION: Conducted research represents opinions and lore about alternative and augmentative communication of only certain group of physiotherapists in the Republic of Croatia. A more extensive and strictly controlled research on this topic should be conducted, but on a larger sample, as the sample of respondents who approached this research was too small to get a credible picture of physiotherapists knowledge and attitudes about the topic at the state level of Croatia. The research is a good basis and incentive for further research on this problem, which is insufficiently researched in the Republic of Croatia. Also, the contribution of the research is informing a part of the respondents about this theme, who was not familiar with the concept of alternative and augmentative communication before completing the surve.
