Walking Index for Spinal Cord Injury (WISCI): An international multicenter validity and reliability study.
Source: Spinal Cord 38(4):234-243.
Abstract: Study aimed at constructing a walking scale for use in clinical trials of individuals with spinal cord injury (SCI), and determining its validity and reliability. Original items were developed by experts at 2 centers in Italy and the United States. Concurrent validity was determined through comparison with the Functional Independence Measure (FIM). Subsequent independent blind rank ordering of items was completed at 8 SCI centers in Australia, Brazil, Canada (2), Korea, Italy, the United Kingdom, and the United States. Final consensus on rank ordering was reached during an international meeting (face validation). Inter-rater reliability was found to be 100% when 40 video clips of patients walking were examined at all 8 centers. (Rehabdata Abstract)
