Extracorporeal shockwave therapy (ESWT) has expanded from the original uses of human urinary calculi treatment to veterinary orthopaedic applications. This paper investigates the feasibility and efficacy of treating dogs with osteoarthritis of the stifle joint with ESWT. In this study, dogs with persistent stifle lameness despite previous surgical or medical treatment were either treated with ESWT or served as untreated controls. The more lame rear limb of each dog was determined by force platform analysis. The range of motion (ROM) of the stifle joints was assessed by goniometry. Force platform gait analysis and goniometry were performed on both groups for four visits at three-week intervals and a final examination four weeks later. Shock wave therapy was performed three times on the treated dogs, once at each of the first three examinations. A placebo treatment consisting of clipping and wetting the hair was performed on the control dogs. The vertical forces were evaluated for objective analysis of treatment response. For peak vertical force (PVF), four of seven treated dogs improved, while only one of five of control dogs improved. The PVF for the within group analysis did not show any significant change for the treated group, however, the control group has a significant decrease (p = 0.05) in PVF consistent with an increase in lameness. The range of motion (ROM) of the stifle joint improved in five of seven treated dogs and three of five controls. Dogs in the treated group had a trend toward increased ROM (p = 0.07) and a 'positive slope' when compared to dogs in the control group which did not have a significant change (p = 0.78) and had a negative slope indicating the dogs were developing a decrease in ROM. The subjective data provided by client questionnaire did not show significant difference between groups.
体外冲击波疗法（ESWT）已从最初用于治疗人类尿路结石扩展到兽医骨科应用。本文研究了用ESWT治疗犬膝关节骨关节炎的可行性和疗效。在本研究中，尽管先前接受过手术或药物治疗但仍持续出现膝关节跛行的犬只，要么接受ESWT治疗，要么作为未治疗的对照组。通过测力平台分析确定每只犬跛行更严重的后肢。通过测角法评估膝关节的活动范围（ROM）。对两组进行测力平台步态分析和测角法，每隔三周进行四次随访，并在四周后进行最终检查。对治疗组的犬只进行三次冲击波治疗，在前三次检查时各进行一次。对对照组的犬只进行包括剪毛和湿毛的安慰剂治疗。评估垂直力以客观分析治疗反应。对于峰值垂直力（PVF），七只治疗犬中有四只有所改善，而五只对照犬中只有一只有所改善。治疗组组内分析的PVF未显示任何显著变化，然而，对照组的PVF显著降低（p = 0.05），这与跛行增加一致。七只治疗犬中有五只膝关节的活动范围（ROM）有所改善，五只对照犬中有三只有所改善。与对照组犬只相比，治疗组犬只的ROM有增加趋势（p = 0.07）且呈“正斜率”，而对照组犬只无显著变化（p = 0.78）且呈负斜率，表明犬只的ROM在减小。客户问卷提供的主观数据在两组之间未显示出显著差异。
