| Abstract: | The effect of skin resection on joint contracture was determined by comparing the firstmeasurement of range of motion after cast removal and the second measurement after theskin resection. This study aimed to verify that both the joint movement during themeasurement and skin affect range of motion. [Subjects] Twelve female Wistar rats wereused. [Methods] The right hind limb ankle of each rat was immobilized in complete plantarflexion in a cast. In the resection group (n = 6), the skin of the right hind limb anklewas removed surgically, but not in the non-resection group (n = 6). In the resectiongroup, the first measurement of the dorsiflexion angle was obtained after the cast wasremoved, and the second measurement was obtained after skin resection. In thenon-resection group, both measurements of the dorsiflexion angle were obtained soon afterthe cast was removed. [Results] Compared with the non-resection group, the resection groupshowed a significant increase between the first and second measurements of range ofmotion. [Conclusion] These results show that range of motion is substantially affected byskin, in addition to joint movement, during measurement.Key words: Joint contracture, Skin, Rat |
