目的：描述幼年型慢性关节炎（JCA）儿童手部肌肉力量的变化，并检查肌肉力量、局部关节炎和疾病亚型之间的关系。方法：对20例7 ~ 18岁JCA患儿（男10例，女10例）进行2年随访。重复测量腕背屈肌等长肌力和握力。将结果与相同方法的参考值进行比较。每三个月对手部关节炎的严重程度进行评分。神经传导速度测定两次。结果：20名患者中有7名在两项测试中的一项或两项中最初强度较低或下降。在至少一次测试中，20名儿童中有5名儿童的力量下降（比参考组的平均值低两个标准差以上）。在观察期间，4名儿童在至少一次测试中显示肌肉力量明显下降。在四名患有多关节疾病的儿童中测得的力量下降最大。这些儿童的手部也有局部关节炎。与少关节炎儿童相比，多关节炎儿童的力量较低或下降的比例更大。对于手部有活动性关节炎的儿童也是如此。神经传导速度在所有情况下都是正常的，并没有改变。结论：大多数儿童JCA有正常的力量在手中。有些儿童，特别是那些患有多发性关节炎和手部关节炎的儿童，手部肌肉力量减弱。低强度或降低强度的风险因素是手部多关节炎和/或活动性关节炎。
Aim: To describe changes in muscle strength in the hands of children with juvenile chronic arthritis (JCA) and to examine the relationship between muscle strength, presence of local arthritis and disease subtype. Methods: Twenty children (10 girls and 10 boys) with JCA aged 7 to 18 y were followed for two years. Isometric muscle strength in wrist dorsiflexors and handgrip strength were measured repeatedly. The results were compared with reference values for the same methods. Arthritis severity in the hand was scored every third month. Nerve conduction velocities were measured twice. Results: Seven out of 20 patients had initially low or decreasing strength in one or both of the two tests. Five out of 20 children had reduced strength (more than two standard deviations below the mean of the reference group) in at least one test. Four children showed a significant reduction in muscle strength in at least one test during the observation time. The greatest reduction in strength was measured in four children with polyarticular disease. These children also had local arthritis in the hand. A greater proportion of children with polyarthritis had low or decreasing strength compared with children with oligoarthritis. The same was true for children with active arthritis in the hand. Nerve conduction velocities were normal in all cases and did not change.Conclusion: The majority of children with JCA have normal strength in the hand. Some children, especially those with polyarthritis and hand arthritis, have reduced muscle strength in the hand. Risk factors for low or decreasing strength are polyarthritis and/or active arthritis in the hand.
