The aim of the study was to assess reliability, validity and responsiveness of Duruoz Hand Index (DHI), which has been developed for evaluation of activity limitation in rheumatoid arthritis in patients with traumatic hand flexor tendon injuries.
Sixty-five patients older than 16 years who underwent surgical intervention after flexor tendon injuries were enrolled. Reliability was assessed by internal consistency (with Cronbach's-α) and test-retest intraclass correlation coefficient (ICC). Construct validity was estimated correlating the scale with the DASH and VAS-hd. Also responsiveness was estimated using standardised response mean (SRM) and effect size (ES).
Mean age of the patients was 30.25 ± 11.07 years and totally 140 fingers were evaluated. Cronbach's-α and ICC values of DHI were found to be 0.87 and 0.99, respectively. In validation study, highly significant correlation was detected between DHI with DASH and VAS-hd (r = 0.86, r = 0.54, p < 0.0001, respectively). SRM values and ES values (excepting workplaces subgroup score) were higher than 0.80 for total and all subgroup scores.
DHI is a reliable, valid questionnaire to assess hand-related activity limitation in patients with traumatic hand flexor tendon injuries. Also, due to its high level responsiveness DHI can be used for assessing the clinical course of the traumatic hand flexor tendon injured patient.
本研究旨在评估 Duruoz 手指数（DHI）的可靠性、有效性和反应度，该指数是为评估创伤性手部屈肌腱损伤患者的活动受限而开发的。
共纳入 65 名年龄大于 16 岁的接受手部屈肌腱损伤后手术干预的患者。通过内部一致性（Cronbach's-α）和测试-再测试组内相关系数（ICC）评估可靠性。通过与 DASH 和 VAS-hd 相关来评估结构有效性。还使用标准化反应均值（SRM）和效应量（ES）来评估反应度。
患者的平均年龄为 30.25±11.07 岁，总共评估了 140 个手指。DHI 的 Cronbach's-α 和 ICC 值分别为 0.87 和 0.99。在验证研究中，DHI 与 DASH 和 VAS-hd 之间存在高度显著相关性（r=0.86，r=0.54，p<0.0001，分别）。除工作场所亚组评分外，DHI 的 SRM 值和 ES 值（总评分和所有亚组评分）均高于 0.80。
DHI 是一种可靠、有效的问卷，可用于评估创伤性手部屈肌腱损伤患者手部相关活动受限。此外，由于其高度反应度，DHI 可用于评估创伤性手部屈肌腱损伤患者的临床病程。
