Longitudinal associations of chronic pain severity trajectories and number of pain site trajectories with risk of limitations in ability in daily activities: Evidence from two 10-year prospective cohort studies

The research findings underscore the significant role of long-term, persistently high levels and progressively worsening severity of chronic systemic and localized pain in the limitations of ADL functions in older adults. Incorporating longitudinal monitoring of chronic pain severity trajectories into ADL function limitation management programs is crucial for enhancing preventive and therapeutic interventions.
