STUDY DESIGN: Retrospective observational study.
OBJECTIVES: The Capabilities of the Upper Extremity Test (CUE-T) is a tool that assesses upper limb function in detail among individuals with cervical spinal cord injury (CSCI). We aimed to evaluate the predictive validity of the CUE-T for independence in activities of daily living (ADL) at discharge.
SETTING: Spinal cord injury rehabilitation center in Chiba, Japan.
METHODS: The cutoff value for independence in ADL (six self-care items of the spinal cord independence measure III [SCIM Ⅲ]) at the time of discharge from a rehabilitation center was calculated based on the results of the CUE-T conducted within 3 months of injury for individuals with CSCI. We defined a SCIM item score of ≤ 1 as dependence and ≥ 2 as independence. Analyses were performed using a receiver operating characteristic curve; the cutoff value was calculated using the Youden index. Bootstrapping was used for internal validation.
RESULTS: Data were collected from 44 individuals with CSCI (median age: 59.0 [interquartile range, 50.8-67.3] years; men: 38, women: 6; American Spinal Injury Association Impairment Scale A/B: 7; C/D: 37). The cutoff values for the SCIM III self-care items ranged from 13-61 points. All area under the curves were 0.8 or greater, which was similar to the results obtained using bootstrapping.
CONCLUSIONS: The CUE-T cutoff values calculated in this study showed good predictive ability and reproducibility and were clinically useful. These results demonstrate the high predictive validity of the CUE-T.
