BACKGROUND: Cranial cruciate ligament rupture (CCLR) is one of the most important stifle injuries and a common cause of lameness in dogs. Our objective was to measure the vertical forces in the pads of Pitbulls with cranial cruciate ligament rupture (CCLR) using a pressure sensitive walkway. A pressure sensitive walkway was used to collect vertical force data from the pads of 10 Pitbulls affected with unilateral CCLR. Ten healthy Pitbulls were included in the study as controls. Velocity varied between 1.3 and 1.6 m/s and acceleration was kept below ± 0.1 m/s2. Differences between groups and between pads in the same limb within groups were investigated using ANOVA and the Tukey test. The paired Student t-test was employed to assess gait symmetry (p < 0.05). RESULTS: Peak vertical forces (PVF) were lower in the affected limb, particularly in the metatarsal pad. Increased PVF values in the forelimb and the contralateral hind limb pads of affected dogs suggest a compensatory effect. CONCLUSIONS: A consistent pattern of vertical force distribution was observed in the pads of dogs with CCLR. These data are important for increased understanding of vertical force distribution in the limb of dogs with CCLR disease. Kinetic analysis using pressure sensitive walkways can be useful in follow-up assessment of surgically treated dogs regardless of the surgical technique employed.
背景:颅交叉韧带断裂(CCLR)是犬类最重要的 stifle 损伤之一,也是犬类跛行的常见原因。我们的目标是使用压力敏感步道测量患有颅交叉韧带断裂(CCLR)的比特犬脚垫中的垂直力。使用压力敏感步道收集 10 只患有单侧 CCLR 的比特犬脚垫的垂直力数据。10 只健康比特犬作为对照纳入研究。速度在 1.3 至 1.6 m/s 之间变化,加速度保持在±0.1 m/s2 以下。使用方差分析(ANOVA)和 Tukey 检验研究组间以及组内同一肢体不同脚垫之间的差异。采用配对学生 t 检验评估步态对称性(p < 0.05)。 结果:患侧肢体的峰值垂直力(PVF)较低,尤其是在跖骨垫处。患犬前肢和对侧后肢脚垫中 PVF 值增加表明存在代偿作用。 结论:在患有 CCLR 的犬类脚垫中观察到一致的垂直力分布模式。这些数据对于加深对患有 CCLR 疾病犬类肢体垂直力分布的理解很重要。无论采用何种手术技术,使用压力敏感步道进行动力学分析都有助于对接受手术治疗的犬类进行随访评估。
