The longitudinal relationship between fear of movement and physical activity after cardiac hospitalization: A cross lagged panel model.

Background: Little is known about the association between fear of movement (kinesiophobia) and objectively measured physical activity (PA), the first 12 weeks after cardiac hospitalization.

Purpose: To assess the longitudinal association between kinesiophobia and objectively measured PA and to assess the factor structure of kinesiophobia.

Methods: We performed a longitudinal observational study.
