Effects of a tailored activity pacing intervention on pain and fatigue for adults with osteoarthritis.

OBJECTIVE We examined whether tailored activity pacing intervention was more effective at reducing pain and fatigue than general activity pacing intervention. METHOD Adults with knee or hip osteoarthritis (N = 32) stratified by age and gender were randomized to receive either tailored or general pacing intervention. Participants wore an accelerometer for 5 days that measured physical activity and allowed for repeated symptom assessment. Physical activity and symptom data were used to tailor activity pacing instruction. Outcomes at 10-week follow-up were pain (Western Ontario and McMaster Universities Osteoarthritis Index) and fatigue (Brief Fatigue Inventory). RESULTS Compared with general intervention, the tailored group had less fatigue interference (p = .02) and trended toward decreased fatigue severity (p = .09) at 10-wk follow-up. No group differences were found in pain reduction. CONCLUSION Tailoring instruction on the basis of recent symptoms and physical activity may be a more effective symptom management approach than general instruction given the positive effects on fatigue.
