In systemic sclerosis (SSc), hand involvement is frequent and leads to prominent disability. The Hand Mobility in Scleroderma (HAMIS) test is a hand function test for SSc patients assessing the movements included in an ordinary range of motion examination. Our aim is to validate the Italian version of HAMIS, by assessing its test-retest reliability, internal consistency and external consistency in Italian SSc patients.
The Italian version of HAMIS was administered to 40 SSc patients. HAMIS was translated according to international procedures. Test-retest reliability was assessed by intra-class correlation coefficient (ICC), internal consistency by Cronbach's alpha and external consistency by comparison with Cochin Hand Function Scale (CHFS), fist closure, hand opening, HAQ.
HAMIS showed a good testretest reliability (ICCs=0.99 for right and left hand) and internal consistency (Cronbach's α=0.94 for right and 0.93 for left hand) for both hands. A good external consistency was confirmed by the correlation of right and left hand HAMIS with CHFS (p<0.0001, in both cases); fist closure of homolateral hand (p<0.0001 in both cases), opening of homolateral hand (p<0.05 and <0.005, respectively), HAQ (p<0.001 in both cases). HAMIS scores for right and left hands were 7.95±6 .68 and 7.5±6.60 (p=NS), respectively. HAMIS scores for both hands were higher in dSSc and in patients with hand arthritis and flexion contractures.
HAMIS is a hand function test measuring hand disability in SSc. Our results support its validity and reliability in Italian SSc patients.
在系统性硬化症（SSc）中，手部受累很常见，导致明显的残疾。Hand Mobility in Scleroderma（HAMIS）测试是一种用于评估 SSc 患者手部功能的测试，评估了普通活动范围检查中包含的运动。我们的目的是通过评估意大利 SSc 患者的测试 - 重测信度、内部一致性和外部一致性来验证 HAMIS 的意大利版本。
对 40 例 SSc 患者进行了 HAMIS 的意大利语版本。根据国际程序对 HAMIS 进行了翻译。通过组内相关系数（ICC）评估测试 - 重测信度，通过 Cronbach's alpha 评估内部一致性，通过与 Cochin 手部功能量表（CHFS）、握拳、手张开、HAQ 比较评估外部一致性。
HAMIS 显示出良好的测试 - 重测信度（右手和左手的 ICCs=0.99）和内部一致性（右手和左手的 Cronbach's α=0.94 和 0.93）。右手和左手 HAMIS 与 CHFS 的相关性证实了良好的外部一致性（p<0.0001，两种情况均如此）；同侧手握拳（两种情况均 p<0.0001）、同侧手张开（p<0.05 和 p<0.005，分别）、HAQ（两种情况均 p<0.001）。右手和左手的 HAMIS 评分分别为 7.95±6.68 和 7.5±6.60（p=NS）。dSSc 和手部关节炎和屈曲挛缩患者的双手 HAMIS 评分较高。
HAMIS 是一种测量 SSc 患者手部残疾的手部功能测试。我们的结果支持其在意大利 SSc 患者中的有效性和可靠性。
