The questioner "How much do we know about prevention of joint and spine diseases" are presented. Questioner contained 10 questions and two possible answers. This investigation involved 120 medical stuff members, 187 patients on physical therapy and 204 patients with same medical problems without physical therapy. Results are showing no statistically important difference between that two group of patients. More interesting is that there is no difference between medical doctors, physiotherapists and medical technicians comparing to patients. To improve those bad results of medical stuff we suggest that it should be organized in physiatrist ordinations consultations and continuous education with practical examples and advices separately for medical stuff members and patients.
