踝关节活动受限在许多情况下是通过关节松动术(JM)来治疗的，JM是一种手动物理治疗技术。到目前为止，JM入路主要集中在距小腿关节，对下胫腓关节的关注较少。我们像JM一样对外踝施加循环载荷，以明确背屈角度与外踝偏移量之间的关系。实验使用了7条新鲜冷冻的正常身体腿。每个标本以15N/S的速度对外踝施加30N力的循环载荷1000次，用磁跟踪系统测量外踝的位移。在循环负荷前后测量最大背屈角度。第100次和1000次循环载荷后，胫骨位移分别为0.44±-0.30 mm和0.75±-0.36 mm，腓骨分别为0.44±-0.28 mm和0.92±-0.39 mm。循环负荷后平均背屈角度由14.36±7.51度增加到16.74±7.21度(P<；0.05)。远端下胫腓关节的运动导致踝关节背屈范围显著增加。这些结果表明，胫腓骨JM对于限制踝关节背屈是有效的。(C)2009爱思唯尔有限公司。保留所有权利。
Limitation of ankle motion is in many cases treated by joint mobilization (JM), a kind of manual physical therapy technique. Until now, the JM approach has mainly focused on the talocrural joint, with less attention to the distal tibiofibular joint. We applied cyclic loading to the lateral malleolus as in JM in order to clarify the relationship between the dorsiflexion angle and the excursion of the lateral malleolus. Seven normal, fresh-frozen cadaver legs were used. To each specimen, cyclic loading with a 30 N force was applied 1000 times to the lateral malleolus at a speed of 15 N/s. The displacement of the lateral malleolus was measured with a magnetic tracking system. The maximum dorsiflexion angle was measured before and after cyclic loading. After the first 100 and 1000 times of cyclic loading, the tibia was displaced 0.44 +/- 0.30mm and 0.75 +/- 0.36mm, respectively, and the fibula was displaced 0.44 +/- 0.28 mm and 0.92 +/- 0.39 mm, respectively. The average dorsiflexion angle increased from 14.36 +/- 7.51 degrees to 16.74 +/- 7.21 degrees after cyclic loading (P < 0.05). Movement of the distal tibiofibular joint led to a significant increase in the range of ankle dorsiflexion. These results suggest that tibiofibular JM would be effective for limitation of ankle dorsiflexion. (C) 2009 Elsevier Ltd. All rights reserved.
