Clinical investigation revealed a significantly higher rate of a positive anterior drawer and talar tilt (p less then 0.001, respectively), significantly increased supination (p = 0.047) of the right ankle joint and increased plantarflexion (p = 0.009) of the left ankle joint in the FAI group compared with controls. Significantly higher rates of inhomogeneity and hypo-echogenicity were sonographically observed in both ligaments in the FAI group (p less then 0.05, respectively). The anterior talofibular ligament was significantly longer under stress conditions, and the calcaneofibular ligament was significantly longer under both neutral and stress conditions in the FAI group (p less then 0.05, respectively). Peritendinous edema of the peroneal tendons was found in 22% of the FAI group and 6% of controls. Health behaviors shape more than 30% of one's physical and mental health, as well as overall well-being. Yet, changing behavior is difficult. This paper aims first at operationalizing the concept of health behavior by focusing on its main components and determinants. Second, it gives insights into how to influence health behavior by providing an overview of some of the most commonly used approaches to the design of behavioral interventions. This is a position paper that presents a selection of evidence-based theories, models and approaches to understand and address behavior. A health behavior broadly refers to every individual action affecting health, disease, disability, or mortality. Behavior is shaped by factors within the skin (biological, psychological) and outside the skin (interpersonal, environmental, poli
