Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of multiple against single pain intensity measurements in complex regional pain syndrome type I: analysis of 54 patients.
To describe the comparison of multiple and single pain ratings in patients with complex regional pain syndrome type I (CRPS I). ⋯ In patients with CRPS I a single pain rating is an accurate predictor of the average pain measured by a multiple pain-rating test. Moreover, both assessments are accurate enough to determine changes in pain over time with an effective treatment.

Randomized Controlled Trial Comparative Study Clinical Trial
The treatment of fear of movement/(re)injury in chronic low back pain: further evidence on the effectiveness of exposure in vivo.
Several cognitive-behavioral factors contribute to the persistence of pain disability in patients with chronic back pain. Fear-avoidance beliefs and fear of movement/(re)injury in particular have been shown to be strong predictors of physical performance and pain disability. Patients reporting substantial pain-related fear might benefit from exposure in vivo to a set of individually tailored, fear-eliciting, and hierarchically ordered physical movements rather than more general graded activity. ⋯ Time series analysis of the daily measures showed that improvements in pain-related fear and pain catastrophizing occurred only during the exposure in vivo and not during the graded activity, irrespective of the treatment order. Analysis of the pretreatment to post-treatment differences also revealed that decreases in pain-related fear also concurred with decreases in pain disability and pain vigilance and an increase in physical activity levels. All improvements remained at the 1-year follow-up.
