Chiropractic care is a common treatment modality used in equine practice to manage back pain and stiffness but has limited evidence for treating lameness. The objective of this blinded, controlled clinical trial was to evaluate the effect of chiropractic treatment on chronic lameness and concurrent axial skeleton pain and dysfunction. Two groups of horses with multiple limb lameness (polo) or isolated hind limb lameness (Quarter Horses) were enrolled. Outcome measures included subjective and objective measures of lameness, spinal pain and stiffness, epaxial muscle hypertonicity, and mechanical nociceptive thresholds collected on days 0, 14, and 28. Chiropractic treatment was applied on days 0, 7, 14, and 21. No treatment was applied to control horses. Data was analyzed by a mixed model fit separately for each response variable (p < 0.05) and was examined within each group of horses individually. Significant treatment effects were noted in subjective measures of hind limb and whole-body lameness scores and vertebral stiffness. Limited or inconsistent therapeutic effects were noted in objective lameness scores and other measures of axial skeleton pain and dysfunction. The lack of pathoanatomical diagnoses, multilimb lameness, and lack of validated outcome measures likely had negative impacts on the results.
整脊疗法是马匹医疗中用于治疗背部疼痛和僵硬的常见治疗方式，但在治疗跛行方面证据有限。这项双盲对照临床试验的目的是评估整脊疗法对慢性跛行以及并发的轴向骨骼疼痛和功能障碍的影响。招募了两组马匹，一组是有多肢跛行的马（马球用马），另一组是有孤立后肢跛行的马（ Quarter Horses马）。结果测量包括在第0天、第14天和第28天收集的跛行、脊柱疼痛和僵硬、轴后肌肉张力亢进以及机械性伤害感受阈值的主观和客观测量指标。在第0天、第7天、第14天和第21天进行整脊治疗。对对照马不进行治疗。对每个反应变量分别采用混合模型进行数据分析（p<0.05），并在每组马匹中单独进行检查。在后肢和全身跛行评分以及椎体僵硬的主观测量指标中发现了显著的治疗效果。在客观跛行评分以及轴向骨骼疼痛和功能障碍的其他测量指标中发现了有限或不一致的治疗效果。缺乏病理解剖诊断、多肢跛行以及缺乏经过验证的结果测量指标可能对结果产生了负面影响。
