The hands of 45 RA patients were studied for vascular, neurological and functional characteristics. The patients underwent functional tests, dopplerography (to study regional arterial flow) and electroneuromyography (to study the peripheral nerves). Induration and defective elasticity of the vascular wall in the radial and ulnar arteries were disclosed in 74% of the cases. Digital arteries suffered occlusive lesion of degree III-IV in 46% of the examinees. One-third of the patients showed signs of polyneuropathy. Among functional defects, the upper grasp incompetence appeared the first. It is stated that parallel affections of the vascular, neurological and functional origin contribute to deficient functional performance of the hand in RA patients.
对45例类风湿关节炎患者的手部进行了血管、神经和功能特征研究。患者接受了功能测试、多普勒超声检查（以研究局部动脉血流）和肌电图检查（以研究周围神经）。74%的病例显示桡动脉和尺动脉血管壁有硬结和弹性缺陷。46%的受检者指动脉出现III-IV度闭塞性病变。三分之一的患者有多发神经病体征。在功能缺陷中，首先出现的是上肢抓握功能不全。研究表明，血管、神经和功能源性的并行病变导致类风湿关节炎患者手部功能表现不足。
