The Internet and social networking sites have developed considerably in recent years, but few studies have measured their impact on physiotherapy. Objective: To estimate the importance of the Internet and social networks in physiotherapy from the patient's point of view, their frequency of use, and the public's confidence in them. Methods: The measuring instrument is a questionnaire on the importance of the Internet and social networks from the patient's point of view. The questionnaire, which was distributed via social networks and in different public organizations, collected 347 responses on frequency of use, sites consulted and confidence in the internet from patients of all ages and genders. Results: 302 people (87.3%) use the Internet for health information. The most frequently consulted sites were government sites (57.8%), popularization sites (59.8%), scientific articles (35.8%) and social networks (32.8%). 312 patients (90%) had moderate or minimal confidence in the information. The study shows that 343 patients (98.8%) trust their healthcare professionals more than information found on the internet. 322 patients (92.8%) have never received a recommendation from their physiotherapist, while 260 (76.9%) would like to. Conclusion: The use of the Internet is very important and patients expect recommendations from their physiotherapist, as trust in the Internet is lower. The verification of information, its transmission and accessibility can be improved by modern means such as social networks or the use of organizations such as HON (Health On The Net).
