Range of motion (ROM) measured objectively in nodal hand osteoarthritis (NHOA) is missing. Evaluation of collateral ligaments by ultrasound (US) is unknown in NHOA also. To compare ROM in interphalangeal joints in housewives with nodal OA, with a control group by a digital system using angle to voltage (Multielgon). The second objective was to assess correlation between collateral radial and ulnar ligaments thickness and ROM. For this cross-sectional observational study, we assessed 60 hands with symptomatic NHOA and 30 hands of healthy housewives matched for age. We obtained clinical and demographic characteristics (a complete standardized physical examination of hand joints, DASH questionnaire, pain surveys, gross grasp hand goniometer, and ROM measurements by Multielgon. Presence of synovitis, power Doppler signal, osteophytes, and collateral ligaments thickness was evaluated by US. We used descriptive statistics, Spearman correlation, X test, t test and odds ratio. Significant less gross grasp and ROM in the right hand were observed in NHOA (p = 0.01 for both). Presence of OA, painful joints, disease duration, and score DASH were significant correlated with reduced ROM (OR 4.12, 4.12, 1.04 and 1.09, respectively). Reduced ROM was statistical significant in thumb MCP and IP joints, second and third DIP in dominant hand. There was no association between collateral radial and ulnar ligaments and reduced ROM. Synovitis and osteophytes were more prevalent in OA group. Multielgon demonstrated the pattern of reduced ROM in nodal OA of housewives particularly in MCP and IP thumb joints, second and third distal interphalangeal joints.
活动度（ROM）在指间手骨关节炎（NHOA）的节点中客观测量缺失。超声（US）评估 collateral 韧带在 NHOA 中也是未知的。为了比较家庭主妇节点 OA 与对照组指间关节的 ROM，使用角度到电压的数字系统（Multielgon）。第二个目的是评估 collateral 桡侧和尺侧韧带厚度与 ROM 之间的相关性。进行这项横断面观察性研究，我们评估了 60 只手部有症状的 NHOA 和 30 只手部年龄匹配的健康家庭主妇。我们获得了临床和人口统计学特征（手部关节的完整标准化体检、DASH 问卷、疼痛调查、大体抓握手测角计和 Multielgon 的 ROM 测量）。通过 US 评估滑膜炎、功率多普勒信号、骨赘和 collateral 韧带厚度。我们使用描述性统计、Spearman 相关、X 检验、t 检验和优势比。在 NHOA 中，右手的大体抓握和 ROM 明显减少（两者均为 p=0.01）。OA 的存在、疼痛关节、疾病持续时间和 DASH 评分与 ROM 减少显著相关（OR 分别为 4.12、4.12、1.04 和 1.09）。在优势手的拇指 MCP 和 IP 关节、第二和第三 DIP 关节中，ROM 减少具有统计学意义。collateral 桡侧和尺侧韧带与 ROM 减少之间没有关联。滑膜炎和骨赘在 OA 组中更为常见。Multielgon 显示了家庭主妇节点 OA 中 ROM 减少的模式，特别是在拇指 MCP 和 IP 关节、第二和第三远节指间关节。
