To assess joint kinematics in dogs with osteoarthritis of the hip joints during walking up an incline or down a decline and over low obstacles and to compare findings with data for nonlame dogs.
10 dogs with osteoarthritis of the hip joints (mean ± SD age, 6.95 ± 3.17 years; mean body weight, 34.33 ± 13.58 kg) and 8 nonlame dogs (3.4 ± 2.0 years; 23.6 ± 4.6 kg).
Reflective markers located on the limbs and high-speed cameras were used to record joint kinematics during walking up an incline or down a decline and over low obstacles. Maximal flexion, extension, and range of motion of the hip joints were calculated.
Osteoarthritis of the hip joints reduced extension of both hip joints and flexion of the contralateral hind limb, compared with flexion of the lame hind limb, during walking down a decline. Walking up an incline resulted in decreased extension of the stifle joint in both hind limbs of osteoarthritic dogs; extension was significantly decreased for the lame hind limb. During walking over low obstacles, maximal flexion of the stifle joint was increased significantly for the contralateral hind limb. Maximal flexion was increased in both tarsal joints.
Osteoarthritis of the hip joints led to complex changes in the gait of dogs, which involved more joints than the affected hip joint alone. Each exercise had specific effects on joint kinematics that must be considered when planning a rehabilitation program.
评估患髋关节骨关节炎的犬只在上坡、下坡及越过低矮障碍物行走时的关节运动学情况，并将结果与非跛行犬的数据进行比较。
10只患髋关节骨关节炎的犬（平均±标准差年龄，6.95±3.17岁；平均体重，34.33±13.58千克）和8只非跛行犬（3.4±2.0岁；23.6±4.6千克）。
使用安装在肢体上的反光标记和高速摄像机记录犬只在上坡、下坡及越过低矮障碍物行走时的关节运动学情况。计算髋关节的最大屈曲、伸展和运动范围。
与跛行后肢的屈曲相比，患髋关节骨关节炎的犬只在下行时，两侧髋关节的伸展及对侧后肢的屈曲均减少。在上坡时，患骨关节炎犬只的两侧后肢膝关节伸展均减少；跛行后肢的伸展显著减少。在越过低矮障碍物行走时，对侧后肢膝关节的最大屈曲显著增加。跗关节的最大屈曲均增加。
髋关节骨关节炎导致犬只步态发生复杂变化，涉及的关节不止患侧髋关节。每种运动对关节运动学都有特定影响，在制定康复计划时必须予以考虑。
