The Relationship Among Pain, Intrinsic Capacity, and Fear of Movement in Patients with Knee Osteoarthritis: A Moderated Network Analysis
By Yan Z, Zhang F, Lu M and 2 others.
Abstract
Objective
To investigate the relationship between intrinsic capacity (IC) and fear of movement, and to clarify how pain modified the relationship between IC and fear of movement at the symptom-level in patients with knee osteoarthritis (KOA).
Methods
In this cross-sectional observational study, 452 patients with KOA were recruited from a tertiary hospital in China. All participants completed validated self-report questionnaires to assess IC, pain, and fear of movement. Symptom-level network visualization and centrality analyses were conducted via moderated network analysis. The Johnson-Neyman technique was further applied to verify and quantify statistically significant moderated network edges.
