The underwater treadmill (UWTM) is utilized in dogs recovering from thoracolumbar intervertebral disc extrusion (TL-IVDE). Gait scoring is validated for dogs with TL-IVDE walking on the land treadmill (LT) but has not been reported for the UWTM. Our objective was to investigate if LT gait analysis could be applied to the UWTM and if non-ambulatory dogs walking unassisted on the UWTM, at a standardized water level, would be more likely to generate gait scores compared to on the LT. This was a prospective, observational study in dogs with TL-IVDE managed surigcally. At 0, 2, 4, 8 and 12 weeks post-operatively, paired video footage of dogs walking on the LT and UWTM (water level at the greater trochanter) was used to generate 0-100 stepping (SS) and coordination (regularity index, RI) scores. Scores were compared between treadmill type and over time. Twenty dogs were enrolled and seventy-eight paired recordings were available for review. Median gait scores increased over time but did not differ by treadmill type (P = 0.262 for SS, P = 0.533 for RI). Combining SS and RI, more recordings received scores of 0 for the LT (n = 58/156; 37.2 %) compared to the UWTM (n = 44/156; 28.2 %; P = 0.043). Scores of 0, at visits when there was at least movement present at multiple joints, was more common on the LT (n = 11/108; 10.2 %) compared to the UWTM (n = 2/108, 1.9 %; P = 0.026). In dogs recovering from TL-IVDE, LT-based gait scoring was feasible in dogs walking on the UWTM and might complement other gait analysis methods, especially for non-ambulatory dogs.
水下跑步机 (UWTM) 用于治疗胸腰椎椎间盘突出症 (TL-IVDE) 后康复的犬。TL-IVDE 犬在陆地跑步机 (LT) 上行走的步态评分已得到验证，但 UWTM 上的步态评分尚未报道。我们的目的是研究 LT 步态分析是否可以应用于 UWTM，以及在标准化水位下，不能在 UWTM 上自主行走的非运动犬是否比在 LT 上更有可能产生步态评分。这是一项前瞻性、观察性研究，研究对象为接受手术治疗的 TL-IVDE 犬。术后 0、2、4、8 和 12 周，使用 LT 和 UWTM（大转子上方水位）上的配对视频片段生成 0-100 步（SS）和协调（规则指数，RI）评分。比较了两种跑步机类型之间和随时间的评分。共纳入 20 只犬，共 78 对记录可用于审查。中位步态评分随时间增加，但与跑步机类型无关（SS 的 P 值为 0.262，RI 的 P 值为 0.533）。将 SS 和 RI 结合起来，LT 上获得 0 分的记录更多（n=58/156；37.2%），而 UWTM 上获得 0 分的记录较少（n=44/156；28.2%；P=0.043）。在 LT（n=11/108；10.2%）上，当至少有多个关节有运动时，在多个访视中记录到 0 分的情况更常见，而在 UWTM（n=2/108，1.9%；P=0.026）上则较少见。在 TL-IVDE 犬的康复过程中，在 UWTM 上行走的犬进行基于 LT 的步态评分是可行的，可能是对其他步态分析方法的补充，特别是对非运动犬。
