Comparative Study Clinical Trial
Comparison of daily, weekly or monthly pain assessments in hip and knee osteoarthritis. A 29-day prospective study.
To compare the accuracy of daily and recalled pain measurements in hip and knee osteoarthritis (OA). ⋯ In hip and knee OA, prospective daily pain assessment can be performed either by assessing 'usual pain' or 'worst pain' of the day. When recalled over one and four weeks, recall pain intensity is well correlated with calculated mean of prospective daily pain assessments during the same period, but correlations are weaker as the length of period increases. Either for 1 and 4 weeks, retrospective assessments are influenced by current pain intensity at the end of the period.
