甘蔗截肢对髋关节生物力学的影响已经得到了很好的研究，但其对胫骨应变和应变率的影响尚不清楚。为了检验手杖使用可能降低行走过程中胫骨应变和应变率的假设，在7名男性志愿者的胫骨中段骨干的右内侧皮质上安装经皮轴向引伸计。测量同侧和对侧手杖使用的体内峰-峰轴向胫骨应变和应变率，并与无手杖对照组进行比较。未发现手杖辅助截肢术显著降低应变幅度;然而，同侧和对侧手杖使用均显著降低胫骨应变率。我们的结论是，无论是同侧或对侧手杖的使用可能是有益的，当需要降低胫骨应变率，如在胫骨应力性骨折或膝关节骨关节病的治疗。
The effect of cane ambulation on hip biomechanics has been well studied, but its effect on tibial strains and strain rates is not known. To test the hypothesis that cane use may lower tibial strain and strain rates during walking, percutaneous axial extensometers were mounted on the right medial cortex of the midtibial diaphysis in seven male volunteers. In vivo peak-to-peak axial tibial strains and strain rates were measured for ipsilateral and contralateral cane usage and compared with a no cane control. Cane-assisted ambulation was not found to significantly lower strain magnitudes; however, tibial strain rates were significantly lowered by both ipsilateral and contralateral cane usage. We conclude that either ipsilateral or contralateral cane usage may be beneficial when lowering tibial strain rate is desired, such as in the treatment of tibia stress fracture or osteoarthrosis of the knee.
