Objective: It is critical to identify modifiable factors associated with functional recovery from hip fracture. The authors examined the association between pain intensity and two functional endpoints-instrumental activities of daily living and social activity participation-after hip fracture.
Method: A total of 270 cognitively intact, community-dwelling persons older than 65 who underwent surgical hip fracture repair in New Haven, Connecticut, were followed for 12 months.
Results: Pain intensity was strongly negatively associated with both instrumental and social functioning (p values < .001). Increases in pain intensity between 6 and 12 months were also associated with concurrent decreases in function (p values < .001). These relationships were partly explained by depressive symptoms and a marker of physical ability-gait speed.
Discussion: Interventions to control pain may enhance functional status after hip fracture; however, pain relief must be maintained to sustain recovery. Attention to the complex relationships among pain, depressive symptoms, and physical impairments should inform intervention development.
