Scoring the severity of joint involvement in the x-rays of hands of patients with rheumatoid arthritis showed significantly greater joint destruction in the dominant hand. The difference was seen in all the joints, and especially in the wrists, but with the exception of the metacarpophalangeal joint of the thumb. The grip strength was not, however, different in the 2 hands.
对类风湿性关节炎患者手部X线片上关节受累的严重程度进行评分显示,优势手的关节破坏明显更严重。在所有关节中都存在这种差异,尤其是在腕关节,但拇指的掌指关节除外。然而,两只手的握力并无差异。
