BACKGROUND/OBJECTIVE: Joint deformities in Jaccoud arthropathy (JA), associated with systemic lupus erythematosus (SLE), can lead to a reduction in articular function and an impaired quality of life. There is controversy in the literature as to whether hand dominance contributes to deformities observed in rheumatoid arthritis and other forms of rheumatism. The purpose of this study was to assess whether hand dominance has any influence on the degree of deformity or joint range of motion in patients with JA associated with SLE.
This was a pilot cross-sectional study of 22 female patients (mean age, 46.18 ± 12.61 years) with both SLE and JA. Each patient's hand grip and hand and wrist joint range of motion were assessed by the same examiner. The Wilcoxon test was used to compare the median values of the angles and muscular strength found between the sides.
All the study participants were right-side dominant. The median muscle strength of the right and left hands was 13.25 kilogram-force (KgF) (range, 7.00-18.00 KgF) and 10.50 KgF (range, 7.50-17.25 KgF), respectively. Both the fingers of the right and left hands had a median ulnar drift of 10.00°; however, their ranges differed (right, 4.50° to 20.00°; left: 0.00° to 15.50°). No statistically significant differences were found in the extension angulation of the proximal interphalangeal joints or the flexion of the distal interphalangeal joints of the second to fifth fingers, between the dominant and nondominant hands.
Hand dominance does not seem to influence the degree of JA deformities in patients with SLE.
背景/目的：Jaccoud 关节病（JA）与系统性红斑狼疮（SLE）相关，可导致关节功能下降和生活质量受损。文献中对于手的优势是否会导致类风湿关节炎和其他形式的风湿病中观察到的畸形存在争议。本研究旨在评估 SLE 合并 JA 患者的手优势是否对手部 JA 畸形的严重程度或手部和腕关节活动度有任何影响。
这是一项针对 22 名女性 SLE 合并 JA 患者（平均年龄 46.18±12.61 岁）的初步横断面研究。由同一位检查者评估每位患者的手握力和手部及腕关节活动度。采用 Wilcoxon 检验比较两侧角度和肌肉力量的中位数。
所有研究参与者均为右侧优势手。右手和左手的中位肌肉力量分别为 13.25 千克力（KgF）（范围，7.00-18.00 KgF）和 10.50 KgF（范围，7.50-17.25 KgF）。右手和左手的手指均有 10.00°的尺侧偏斜中位数；然而，它们的范围不同（右手：4.50°至 20.00°；左手：0.00°至 15.50°）。在第二至第五手指的近端指间关节伸展角度或远侧指间关节屈曲方面，优势手和非优势手之间没有统计学上的显著差异。
手的优势似乎不会影响 SLE 患者 JA 畸形的严重程度。
