To investigate whether acupuncture can alter gait in horses as assessed by objective and subjective parameters.
Prospective, randomized, singleblinded, crossover study.
Eight adult horses.
Horses were randomly assigned to a treatment (three acupuncture treatments in 8 days) or control group. Subjective and objective gait analyses were performed before and after each treatment and at 1, 3 and 7 days after the last treatment (time-points 1-9, respectively). Horses were assessed at the trot in a straight line on a hard surface and on the lunge on the left and right reins on a soft surface (conditions 1-3, respectively). After 12 weeks, groups were reversed. Objective gait analysis was performed using inertial sensors and subjective analysis by two board- certified surgeons who reviewed video-recordings. Each limb was assessed for lameness before and after treatment. Lameness and global scores were assigned using 4-point scales. Assessors were blinded to treatment status. The effects of treatment (yes/no), time (1-9) and horse under conditions 1 -3 were compared using a linear mixed-effects model and a generalized estimating equation.
Treatment decreased hip hike difference under all conditions [condition 1: control, 6.3 ± 6.4 mm versus treatment, -0.2 ± 6.4 mm (p = 0.007); condition 2: control, 9.7 ± 7.8 mm versus treatment, 2.8 ± 7.8 mm (p = 0.032); condition 3: control, 7.3 ± 6.3 mm versus treatment, -2.7 ± 6.4 mm (p = 0.003)]. Other parameters also improved significantly under conditions 1 and 3. Based on subjective gait analysis, treatment decreased lameness [odds ratio (OR) 0.51, 95% confidence interval (CI) 0.34-0.78; p = 0.002] but not global (OR 0.53, 95% CI 0.24-1.10; p = 0.12) scores.
Acupuncture can change horses' gaits to a degree appreciable by objective and subjective analyses.
通过客观和主观参数评估，研究针刺是否能改变马的步态。
前瞻性、随机、单盲、交叉研究。
8匹成年马。
将马随机分为治疗组（8天内进行3次针刺治疗）或对照组。在每次治疗前后以及最后一次治疗后的1天、3天和7天（分别为时间点1 - 9）进行主观和客观步态分析。让马在硬地面上直线小跑以及在软地面上分别用左、右缰绳进行绕圈运动时接受评估（分别为条件1 - 3）。12周后，两组互换。使用惯性传感器进行客观步态分析，由两名获得委员会认证的外科医生通过查看视频记录进行主观分析。在治疗前后对每个肢体的跛行情况进行评估。使用4分制对跛行和整体评分进行赋值。评估者对治疗状态不知情。使用线性混合效应模型和广义估计方程比较治疗（是/否）、时间（1 - 9）以及在条件1 - 3下马匹的影响。
在所有条件下，治疗均降低了臀部抬高差异[条件1：对照组，6.3±6.4毫米，治疗组，-0.2±6.4毫米（p = 0.007）；条件2：对照组，9.7±7.8毫米，治疗组，2.8±7.8毫米（p = 0.032）；条件3：对照组，7.3±6.3毫米，治疗组，-2.7±6.4毫米（p = 0.003）]。在条件1和3下，其他参数也有显著改善。基于主观步态分析，治疗降低了跛行程度[优势比（OR）0.51，95%置信区间（CI）0.34 - 0.78；p = 0.002]，但未降低整体评分（OR 0.53，95% CI 0.24 - 1.10；p = 0.12）。
针刺可在一定程度上改变马的步态，这种改变可通过客观和主观分析得以体现。
