Popis: Objective: To assess the reliability of the visual analog scale (VAS) as an outcome measure in patients with chronic pain. Design: Retrospective chart review of patients in a functional restoration program (Functional Recovery Program [FRP]). Setting: Community-based FRP. Participants: 16 patients enrolled in the FRP. Interventions: Not applicable. Main Outcome Measures: The Oswestry Disability Questionnaire (ODQ) for low back pain, Illness Effects Questionnaire (IEQ), and VAS were compared with each other and with 2 functional measures; the 65-foot dash and time on the treadmill. A Pearson 2-tailed correlation analysis was used for the analysis. The correlation coefficients and P values were calculated for the ODQ compared with the VAS, the IEQ compared with the VAS, and each measure compared with the functional activity gains. The difference in scores on admission and at the end of treatment were used for the VAS, ODQ, and IEQ to evaluate change in level of pain and disability perception while the time difference required for completion of the 65-foot dash and aerobic exercise time were used to assess change in functional status. Results: Significant correlation was present between the VAS and IEQ (coefficient=.836, P P P Conclusions: The VAS correlated well with other subjective disability-related scales. However, it did not correlate with actual measured improvement in functional ability. This brings into question the value of the VAS in chronic pain populations as it relates to treatment outcomes. Clearly, patients can functionally perform well despite self-reported pain complaints and some continued perception of disability.
