Duruöz Hand Index (DHI) is a functional disability scale that can be used successfully to assess the functional disability with different hand arthropathies. The hands are frequently involved in diabetic patients. We aimed to examine the use of DHI for its accuracy and ease in assessing these patients.
Forty patients with diabetes mellitus were recruited in this study. Hand pain was assessed with the visual analog scale. Duruöz Hand Index and Hand Functional Index were applied to assess the disability of hand. We evaluated the grip strength and 3 types of pinch strength (tip pinch, lateral or key pinch, and chuck or 3-finger pinch) for the dominant (D) and nondominant (ND) hands of each patient by 2 different kinds of Jamar dynamometers (JA Preston Corp, Jackson, MI).
The Jamar dynamometer scores were as follows (mean [SD]): grip strength-D (21.56 [5.86]), grip strength-ND (16.42 [4.26]), tip strength-D (5.14 [1.50]), tip strength-ND (5.13 [1.42]), lateral strength-D (5.15 [1.52]), lateral strength-ND (5.07 [1.19]), chuck strength-D (5.40 [1.40]), chuck strength-ND (5.33 [1.28]). There was a high correlation between DHI and Hand Functional Index (P < 0.001, rho = 0.586) showing that DHI has good convergent validity. The DHI had significant correlation with nonfunctional parameters such as visual analog scale-pain (P < 0.001), restricted hand motion (P = 0.020), chuck strength-D (P = 0.006), pins test-D (P < 0.001), pins test-ND (P = 0.013), and assembly test (P = 0.025).
The DHI is a practical scale that is efficient in accurate assessment of hand dysfunction in diabetic patients.
Duruöz 手指数（DHI）是一种功能障碍量表，可成功用于评估不同手部关节炎的功能障碍。手部经常受到糖尿病患者的影响。我们旨在检查 DHI 的准确性和易用性，以评估这些患者。
本研究纳入了 40 名糖尿病患者。手部疼痛采用视觉模拟评分法评估。Duruöz 手指数和手部功能指数用于评估手部残疾。我们使用两种不同的 Jamar 测力计（JA Preston Corp，Jackson，MI）评估每位患者的优势（D）和非优势（ND）手的握力和 3 种捏力（指尖捏、侧捏或关键捏、三指捏）。
Jamar 测力计的评分如下（平均值[标准差]）：握力-D（21.56[5.86]）、握力-ND（16.42[4.26]）、指尖力-D（5.14[1.50]）、指尖力-ND（5.13[1.42]）、侧捏力-D（5.15[1.52]）、侧捏力-ND（5.07[1.19]）、三指捏力-D（5.40[1.40]）、三指捏力-ND（5.33[1.28]）。DHI 与手部功能指数高度相关（P<0.001，rho=0.586），表明 DHI 具有良好的收敛效度。DHI 与非功能参数如视觉模拟评分疼痛（P<0.001）、手部运动受限（P=0.020）、D 侧捏力（P=0.006）、D 指夹试验（P<0.001）、ND 指夹试验（P=0.013）和装配试验（P=0.025）显著相关。
DHI 是一种实用的量表，可高效准确地评估糖尿病患者手部功能障碍。
