Association of different pain patterns with physical function in participants with knee osteoarthritis: data from the osteoarthritis initiative.

ABSTRACT:

Background

Pain is a multidimensional experience and a key symptoms of knee osteoarthritis (KOA). However, it remains unknown whether there is a specific pain pattern that is more strongly associated with physical function compared to other pain patterns among individuals with KOA. This study aimed to compare the correlations between different pain patterns and physical function, and identify the most related pain pattern with physical function in KOA.

Methods

412 participants with radiological KOA were included from the Osteoarthritis Initiative (OAI). Pain severity and four pain patterns were assessed, including intermittent, constant, weight-bearing, and non-weight-bearing pain patterns. Physical function was evaluated by the Western Ontario and McMaster Universities Arth
