Teirlinck CH, et al. - Researchers evaluated the value of daily pain measurements in hip osteoarthritis patients, and whether the reliability of retrospective measurements was lower in patients with intermittent pain than in patients with a more constant pain. In this study, more precise or additional information was not achieved with the daily measurements as compared to the retrospective measurements at 6-weeks follow-up. Nonetheless, in patients with a higher intensity of intermittent pain, there was a probability of lower reliability of retrospective measurements.
