Kinesiophobia mediates the influences on attendance at exercise-based cardiac rehabilitation in patients with coronary artery disease

PURPOSE: To identify predictors of attendance at exercise-based cardiac rehabilitation (CR) and to test the hypothesis that kinesiophobia mediates the influence on attendance at CR in patients with coronary artery disease (CAD).

PATIENTS: In total, 332 patients (75 women; mean age 65 ± 9.1 years) with a diagnosis of CAD were recruited at Sahlgrenska University Hospital, Sweden.

METHODS: The patients were tested in terms of objective measurements, self-rated psychological measurements, and level of physical activity. A path model with direct and indirect effects via kinesiophobia was used to predict participation in CR. An exploratory selection of significant predictors was made.

RESULTS: A current incidence of coronary bypass grafting (p < 0.001) and a diagnosis of ST-elevation myocardial infarction (p = 0.004) increased the probability of attendance at CR, while kinesiophobia (p = 0.001) reduced attendance. As a mediator, kinesiophobia was influenced by four predictors and the following indirect effects were found. General health and muscle endurance increased the probability of attendance at CR, while self-rated anxiety and current incidence of heart failure had the opposite effect.

CONCLUSIONS: This study suggests that kinesiophobia has an influence on and a mediating role in attendance at CR. The results need to be further investigated in relation to clinical practice.
