Clinicians use patients' recall of pain and disability relief as indicators of therapeutic effectiveness. Recall can change over time, however, and is influenced by factors other than true relief, including current health status. We have determined the trend in the relative contribution of current pain/disability and actual relief (current-baseline score) to relief recall over the course of 1 year. ⋯ Complaint characteristics including LBP chronicity, sciatica, LBP history, and comorbidity; psychosocial variables including stress, depression, and well being; sociodemographics; and treating provider type are not important independent predictors of pain and disability relief recall in ambulatory LBP patients. Perceived relief is too weakly related to present pain and disability to be accurate enough for use as a clinical assessment tool for individual patients. Physicians may need to use objective relief data to give the patient a realistic idea of actual improvement.

A reliability and validity study of a previously translated version of the Roland-Morris Disability Questionnaire (RMDQ). ⋯ The RMDQ is a robust unidimensional ordinal measure, largely free of differential item functioning, which works well in the Turkish population. Nonparametric effect sizes of ordinal scales are found to overestimate or underestimate the true effect size depending on the nature of the scale and the distribution of patients at baseline.

Review Case Reports
Chemical sympathectomy for neuropathic pain: does it work? Case report and systematic literature review.
To determine if chemical sympathectomy successfully reduces limb neuropathic pain. ⋯ Based on the case reported and systematic literature review, chemical sympathectomy seems to have at best a temporary effect, limited to cutaneous allodynia. Despite the popularity of chemical sympatholysis, only few patients and poorly defined outcomes are reported in the literature, substantiating the need for well-designed studies on the effectiveness of the procedure.
