Objectives: Ambulation is a primary goal of the individual who sustains a spinal cord injury(SCI). The Walking Index for Spinal Cord Injury II (WISCI II ) was cited as one of the most reliable measures of the function of walking in SCI clinical trials in the published guidelines developed by the International Campaign for Cure of Spinal Cord Paralysis. In China, there is still no research on reliability of the WISCI II . The purpose of this study is to translate the Walking Index for Spinal Cord Injury II into Chinese and to assess the reliability of the Chinese version of WISCI II in patients with spinal cord injury.
Design: Thirty patients, with average age of 42.7 years. Level:13 cervical,9 thoracic,8 lumber; ASIA (American Spinal Injury Association) impairment scale (AIS) grade: 27 D/3 C. Assessment of maximum WISCI II levels by two trained, blinded raters to evaluate test-retest and intra-rater reliability.
Results: The intra-rater reliability was 0.991 for therapists A and 0.986 for therapists B, for the maximum WISCI II level. The test-retest reliability for the maximum WISCI II score was 0.984 on day 1 and 0.976 on day 2.
The Chinese version of WISCI II has high test-retest and intra-rater reliability when administered by trained raters.
