AI Article Synopsis
- The study aimed to explore how different types of physical function measurements (patient-reported, performance-based, and objective) relate to each other and how psychosocial factors influence these measurements among chronic pain patients.
- It involved 79 patients who assessed their physical function, pain coping strategies, and social-emotional factors through various tests, including a 6-minute walk test and accelerometer step counts.
- The results indicated that performance-based and objective measures were connected, but patient-reported disability did not correlate with them, suggesting that self-reported physical function may not accurately reflect actual physical capacity or activity levels.
Article Abstract
Background: Improving all aspects of physical function is an important goal of chronic pain management. Few studies follow recent guidelines to comprehensively assess physical function via patient-reported, performance-based, and objective/ambulatory measures.
Purpose: To test 1) the interrelation between the 3 types of physical function measurement and 2) the association between psychosocial factors and each type of physical function measurement.
Methods: Patients with chronic pain (N=79) completed measures of: 1) physical function (patient-reported disability; performance-based 6-minute walk-test; objective accelerometer step count); 2) pain and non-adaptive coping (pain during rest and activity, pain-catastrophizing, kinesiophobia); 3) adaptive coping (mindfulness, general coping, pain-resilience); and 4) social-emotional dysfunction (anxiety, depression, social isolation and emotional support). First, we tested the interrelation among the 3 aspects of physical function. Second, we used structural equation modeling to test associations between psychosocial factors (pain and non-adaptive coping, adaptive coping, and social-emotional dysfunction) and each measurement of physical function.
Results: Performance-based and objective physical function were significantly interrelated (=0.48, <0.001) but did not correlate with patient-reported disability. Pain and non-adaptive coping (=0.68, <0.001), adaptive coping (=-0.65, <0.001) and social-emotional dysfunction (=0.65, <0.001) were associated with patient-reported disability but not to performance-based or objective physical function (ps>0.1).
Conclusion: Results suggest that patient-reported physical function may provide limited information about patients' physical capacity or ambulatory activity. While pain and non-adaptive reactions to it, adaptive coping, and social-emotional dysfunction may potentially improve patient-reported physical function, additional targets may be needed to improve functional capacity and ambulatory activity.
