To compare the accuracy of daily and recalled pain measurements in hip and knee osteoarthritis (OA).
A prospective study investigating pain intensity over 29 days in patients with painful OA. Pain was assessed on days 1 and 29 during visits. Between these two visits, daily (worst, least, usual, mean, at rest and during daily life) and recalled pain intensities were randomly recorded by telephone interview with a numerical rating scale.
We studied 129 patients, with a mean age of 67.7 ± 10.0 years, 27.1% males. Daily prospective assessments demonstrated that the strongest correlations were between 'mean daily' and 'usual' pain (r=0.88) and between 'mean daily' and 'worst' pain (r=0.86). Retrospective assessments demonstrated a strong correlation between recalled pain intensities and calculated mean of daily assessments over the seven and 28 days (0.78 and 0.67, respectively), but weakened by adjustment for pain intensity on the day of recalled pain assessment. Anxiety and depression scores did not affect pain recall for 7 and 28 days.
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.
比较髋关节和膝关节骨关节炎（OA）患者日常和回忆性疼痛测量的准确性。
一项前瞻性研究调查了 29 天内疼痛性 OA 患者的疼痛强度。在就诊时评估第 1 天和第 29 天的疼痛。在这两次就诊之间，通过电话访谈用数字评分量表随机记录日常（最痛、最轻、通常、平均、休息时和日常生活时）和回忆性疼痛强度。
我们研究了 129 名患者，平均年龄为 67.7±10.0 岁，男性占 27.1%。日常前瞻性评估表明，“平均日常”和“通常”疼痛之间的相关性最强（r=0.88），“平均日常”和“最痛”疼痛之间的相关性最强（r=0.86）。回顾性评估表明，回忆性疼痛强度与计算的 7 天和 28 天内日常评估平均值之间存在很强的相关性（分别为 0.78 和 0.67），但在调整回忆性疼痛评估当天的疼痛强度后，相关性减弱。焦虑和抑郁评分不会影响 7 天和 28 天的疼痛回忆。
在髋关节和膝关节 OA 中，日常疼痛的前瞻性评估可以通过评估当天的“通常疼痛”或“最痛疼痛”来进行。当回忆 1 周和 4 周时，回忆性疼痛强度与同期前瞻性日常疼痛评估的计算平均值密切相关，但随着时间的延长，相关性减弱。无论是在 1 周还是 4 周，回顾性评估都受到该时间段结束时当前疼痛强度的影响。
