ObjectiveTo determine the reliability and validity of the capabilities of upper extremity test (CUE-T), a measure of functional limitations, in patients with chronic tetraplegia.DesignRepeated measures.SettingOutpatient rehabilitation center.ParticipantsFifty subjects (36 male/14 female) with spinal cord injury (SCI) of ≥1-year duration participated. Subjects were 17-81 years old (mean 48.1 ± 18.2); neurological levels ranged from C2 through T6, American Spinal Injury Association Impairment Scale grades A-D.InterventionsNot applicable.Outcome MeasuresIntraclass correlation coefficients (ICC), weighted kappa and repeatability values for CUE-T; Spearman correlations of CUE-T with upper extremity motor scores (UEMS), and self-care and mobility portions of the Spinal Cord Independence Measure, vIII (SCIM III).ResultsScore ranges for UEMS were 8-50, CUE-T 7-135, self-care SCIM 0-20, and mobility SCIM 0-40. The ICC values for total, right, and left side scores were excellent (0.97-0.98; 95% confidence interval 0.96-0.99). Item weighted kappa values were ≥0.60 for all but five items, four of which were right and left pronation and supination. Repeatability of total score was 10.8 points, right and left sides 6.3 and 6.1 points. Spearman correlations of the total CUE-T with the UEMS and SCIM self-care and mobility scores were 0.83, 0.70, and 0.55 respectively.ConclusionsThe CUE-T displays excellent test-retest reliability, and good-excellent correlation with impairment and capacity measures in persons with chronic SCI. After revising pronation and supination test procedures, the sensitivity to change should be determined.
