Kinesiophobia in Patients With Angina Pectoris: A Latent Profile Analysis

Area of Science:

• Cardiology
• Psychology
• Rehabilitation Medicine

Background:

• Kinesiophobia, or fear of movement, significantly hinders exercise rehabilitation in patients with angina pectoris (AP).
• Understanding the varied nature of kinesiophobia and its influencing factors is crucial for improving rehabilitation adherence and quality of life in AP patients.

Purpose of the Study:

• To identify and characterize distinct latent subgroups of kinesiophobia among patients diagnosed with angina pectoris.
• To analyze the demographic and clinical differences between these identified kinesiophobia subgroups.

Main Methods:

• A cross-sectional survey involving 210 angina pectoris patients from four tertiary hospitals in Zhejiang, China.
• Latent class analysis using the Tampa Scale for Kinesiophobia Heart to identify kinesiophobia profiles.
• Multinomial logistic regression to determine factors predicting class membership.

Main Results:

• Three distinct latent classes of kinesiophobia were identified: high-fear (motor avoidance), intermediate-fear (moderate motor fear), and low-fear (danger perception).
• Significant differences in educational level, exercise frequency, pain severity, pain catastrophizing, angina stability, and anxiety levels were found across the three classes.

Conclusions:

• Kinesiophobia in angina pectoris patients is heterogeneous, manifesting in three identifiable subtypes.
• Interventions for kinesiophobia should be individualized based on these subtypes to enhance rehabilitation adherence and patient outcomes.
