Input: Context: Cross-sectional, clinical measurement.', 'To investigate the validity of the Duruoz Hand Index (DHI) in the assessment of hand function in patients with tetraplegia.', "A total of 40 patients with tetraplegia participated. Patients' upper extremities were assessed on the level of 'body function and structure' [The American Spinal Cord Injury Association (ASIA) Impairment Scale (AIS) 2000 revised criteria, upper extremity motor score (UEMS), neurologic level of injury and visual analogue scale of hand function (VAS-HF)], 'activity' [DHI and Quadriplegia index of function-short form (QIF-SF)] and 'body function and structure, activity and participation' [Health Survey Short Form-36 (SF-36)] according to International Classification of Function.", 'The DHI showed significant correlations with UEMS, AIS, QIF-SF, VAS-HF, physical functioning and physical compound summary scores of SF-36.
