The pathological mobility of the metacarpo-phalangeal joints of 100 patients affected by rheumatoid arthritis was studied, and the results were analysed and compared with the results obtained in a control non-rheumatoid group. This report seems to suggest that rheumatoid metacarpo-phalangeal joints become more lax the longer the rheumatoid disease has been present. However, when there is marked local involvement of the joint this hyperlaxity cannot be proven because of pain and/or mechanical blockage.
对100名类风湿性关节炎患者掌指关节的病理性活动度进行了研究，并对结果进行了分析，同时与非类风湿性对照小组的结果进行了比较。该报告似乎表明，类风湿性疾病存在的时间越长，类风湿性掌指关节就越松弛。然而，当关节出现明显的局部受累时，由于疼痛和/或机械性阻碍，这种过度松弛无法得到证实。
