Perceptions of Kinesiophobia in Relation to Physical Activity and Exercise After Myocardial Infarction: A Qualitative Study.

Abstract

Physical activity and exercise are central components in rehabilitation after a myocardial infarction. Kinesiophobia (fear of movement) is a well-known barrier for a good rehabilitation outcome in these patients; however, there is a lack of studies focusing on the patient perspective. The aim of this study was to explore patients' perceptions of kinesiophobia in relation to physical activity and exercise 2 to 3months after an acute myocardial infarction. This qualitative study design used individual semi-structured interviews. Face-to-face interviews were conducted with 21 patients post-myocardial infarction who were screened for kinesiophobia (≥32 on the Tampa Scale for Kinesiophobia Heart). The interviews were transcribed and analyzed according to an inductive content analysis. An overarching theme was defined as "coping with fear of movement after a myocardial infarction-a dynamic process over time" comprising 2 subthemes and explaining how coping with kinesiophobia runs in parallel processes integrating the patient's internal process and a contextual external process. The 2 processes are described in a total of 8 categories. The internal process was an iterative process governed by a combination of factors: ambivalence, hypervigilance, insecurity about progression, and avoidance behavior. The external process contains the categories of relatives' anxiety, prerequisites for feeling safe, information, and the exercise-based cardiac rehabilitation program. Coping with fear of movement after a myocardial infarction is a dynamic process that requires internal and external support. To further improve cardiac rehabilitation programs, person-centered strategies that support the process of each person-as well as new treatment strategies to reduce kinesiophobia-need to be elaborated. Patients with a myocardial infarction were found to be ambivalent about how they expressed their fear of movement; therefore, it is crucial for physical therapists to acknowledge signs of fear by listening carefully to the patient's full story in addition to using adequate self-reports and tests of physical fitness. These results will inform the design, development, and evaluation of new treatment strategies, with the overall aim of reducing kinesiophobia and increasing physical activity and participation in exercise-based cardiac rehabilitation.
