Psoriatic arthritis is an inflammatory arthropathy accompanied by peripheral and axial joint involvement. Hand involvement has been demonstrated by various imaging methods in patients with psoriatic arthritis. However, few studies evaluated the hand in terms of functionality. The aim of the study is to compare hand functions and wrist joint position sense in psoriatic arthritis with rheumatoid arthritis and healthy controls.
Patients with psoriatic arthritis (n = 21), rheumatoid arthritis (n = 21), and healthy controls (n = 21) were included in this cross-sectional study. The measurements were performed by a hand dynamometer for grip strength and endurance, and by a pinchmeter for pinch strength. Disability of Arm, Shoulder, and Hand Questionnaire was used to evaluate the functional disability. A goniometric test was used to assess wrist joint position sense.
Patients with psoriatic arthritis had worse hand functional outcomes and higher position errors than healthy controls (p < 0.05). In addition, in terms of all variables, patients with psoriatic arthritis were found to be similar to the patients with rheumatoid arthritis (p > 0.05).
Our study revealed that hand functions and wrist joint position sense were affected as much in patients with psoriatic arthritis as in patients with rheumatoid arthritis whose hand involvement is frequently reported in the literature. The grip endurance in psoriatic arthritis was assessed for the first time. Our results highlighted the necessity of treatment programs that include strength, endurance, and proprioception in patients with psoriatic arthritis who have hand involvement at least as much as those with rheumatoid arthritis.
银屑病关节炎是一种伴有外周和轴向关节受累的炎症性关节病。各种影像学方法已在银屑病关节炎患者中显示手部受累。然而，很少有研究从功能方面评估手部。本研究的目的是比较银屑病关节炎、类风湿关节炎和健康对照组患者的手部功能和腕关节位置感。
本横断面研究纳入了 21 例银屑病关节炎患者、21 例类风湿关节炎患者和 21 例健康对照者。使用握力计和握力耐力计测量握力，使用捏力计测量捏力。使用手臂、肩部和手部残疾问卷评估功能障碍。使用关节角度计测试评估腕关节位置感。
银屑病关节炎患者的手部功能结局和位置误差均较健康对照组差（p<0.05）。此外，在所有变量方面，银屑病关节炎患者与类风湿关节炎患者相似（p>0.05）。
我们的研究表明，银屑病关节炎患者的手部功能和腕关节位置感与文献中经常报道的手部受累的类风湿关节炎患者一样受到影响。银屑病关节炎的握力耐力是首次进行评估。我们的结果强调了在至少与类风湿关节炎患者一样有手部受累的银屑病关节炎患者中，治疗方案包括力量、耐力和本体感觉的必要性。
