title: Effect of tailored activity pacing on self-perceived joint stiffness in adults with knee or hip osteoarthritis.
abstract: OBJECTIVE
  We examined the effects of a tailored activity-pacing intervention on self-perceived joint stiffness in adults with osteoarthritis (OA).
  
  
  METHODS
  Thirty-two adults with hip or knee OA were randomized to a tailored or general activity-pacing intervention. Participants' symptoms and physical activity over 5 days were used to tailor activity pacing. The outcome was self-perceived joint stiffness measured at baseline, 4 wk, and 10 wk. A linear mixed regression model was used.
  
  
  RESULTS
  The tailored group significantly improved in stiffness compared with the general group over time. We found a significantly different linear trend between groups (Time × Group, p = .046) in which the tailored group had decreasing stiffness over the three time points, denoting continued improvement. The general group's stiffness improved from baseline to 4 wk but returned to baseline levels at 10 wk.
  
  
  CONCLUSIONS
  Tailoring activity pacing may be effective in sustaining improvements in self-perceived joint stiffness in adults with OA.
