The effect of skin resection on joint contracture was determined by comparing the first measurement of range of motion after cast removal and the second measurement after the skin resection. This study aimed to verify that both the joint movement during the measurement and skin affect range of motion. [Subjects] Twelve female Wistar rats were used. [Methods] The right hind limb ankle of each rat was immobilized in complete plantar flexion in a cast. In the resection group (n = 6), the skin of the right hind limb ankle was removed surgically, but not in the non-resection group (n = 6). In the resection group, the first measurement of the dorsiflexion angle was obtained after the cast was removed, and the second measurement was obtained after skin resection. In the non-resection group, both measurements of the dorsiflexion angle were obtained soon after the cast was removed. [Results] Compared with the non-resection group, the resection group showed a significant increase between the first and second measurements of range of motion. [Conclusion] These results show that range of motion is substantially affected by skin, in addition to joint movement, during measurement.
通过比较拆除石膏后首次测量的关节活动范围与皮肤切除术后第二次测量的结果，来确定皮肤切除对关节挛缩的影响。本研究旨在验证测量过程中的关节活动和皮肤均会影响关节活动范围。[研究对象]使用了12只雌性Wistar大鼠。[方法]将每只大鼠的右后肢踝关节固定在石膏中，使其完全跖屈。切除组（n = 6）通过手术切除右后肢踝关节的皮肤，而非切除组（n = 6）则不进行切除。在切除组中，拆除石膏后获得背屈角度的首次测量值，皮肤切除后获得第二次测量值。在非切除组中，拆除石膏后不久即获得背屈角度的两次测量值。[结果]与非切除组相比，切除组在首次和第二次测量的关节活动范围之间显示出显著增加。[结论]这些结果表明，在测量过程中，除了关节活动外，皮肤对关节活动范围也有显著影响。
