The paretic limb is spared in patients who develop rheumatic diseases after a hemiplegic stroke. This has been described previously in rheumatoid arthritis, gout, and osteoarthritis. A similar presentation in a case of scleroderma is described in this report. Scleroderma skin changes are absent in the completely paretic limb and were markedly reduced in the weak left leg. Inflammation may be modified either by neuropeptides or by an anatomical neurological lesion and this may explain the phenomenon.
在偏瘫性卒中后患上风湿性疾病的患者中，瘫痪侧肢体未受累。此前在类风湿关节炎、痛风和骨关节炎中已有此类描述。本报告描述了一例硬皮病患者的类似表现。完全瘫痪的肢体未出现硬皮病皮肤改变，左侧虚弱的腿部硬皮病皮肤改变明显减轻。炎症可能由神经肽或解剖学上的神经病变所改变，这或许可以解释这一现象。
