Meta Analysis
A meta-analysis of outcome rating scales in foot and ankle surgery: is there a valid, reliable, and responsive system?
Rating scales that are valid, reliable, and responsive communicate the severity of a functional problem, facilitate the accurate study of treatment modalities, and provide a common language for those involved in research. The purpose of this study was to determine which outcome rating scales are currently used in the foot and ankle literature and to identify rating scales with proven reliability, validity, and responsiveness. ⋯ The development of a reliable, valid, and responsive rating scale would have value not only in assessing patient outcomes but also in reporting the results of clinical studies in foot and ankle surgery.
