The responsiveness and the intertester reliability of the Finnish Canine Stifle Index (FCSI) were tested, and a cut-off between compromised and severely compromised performance level was set.
Three groups of dogs were used, 29 with any stifle dysfunction (STIF), 17 with other musculoskeletal disease except stifle (OTHER) and 11 controls (CTRL). All dogs were tested with the FCSI by the same physiotherapist at three occasions, at baseline, at six weeks and 10 weeks, and once also by another physiotherapist.
Dogs in the STIF group demonstrated significantly higher (P<0.001) FCSI scores than in OTHER or CTRL groups at baseline. Only the STIF group showed a significant (P<0.001) change in FCSI score at all time points, indicating responsiveness to change. There were no significant differences between the evaluators (P=0.736), showing good intertester reliability, supported by moderate to good (0.78) intraclass correlation coefficient (ICC). The evaluator performing the FCSI did not have a significant effect when comparing the groups of dogs (P=0.214). The 95 per cent confidence intervals of the ICC per group were 0.79 (0.60, 0.91) for STIF, 0.83 (0.53, 0.96) for OTHER 0.78 (0.64, 0.88) for all dogs. A cut-off differentiating a severely compromised from a compromised performance was set at 120, having sensitivity of 83 per cent and specificity of 89 per cent.
The FCSI is a recommendable measure of dogs' stifle functionality.
本研究旨在测试芬兰犬膝关节指数（FCSI）的反应性和测评者间信度，并设定一个临界值来区分膝关节功能轻度受损和严重受损的情况。
本研究共纳入 3 组犬，29 只为膝关节功能障碍犬（STIF），17 只为膝关节以外的其他肌肉骨骼疾病犬（OTHER），11 只为健康对照犬（CTRL）。所有犬只由同一位物理治疗师在基线时、6 周和 10 周时分别进行 3 次 FCSI 测试，另外还由另一位物理治疗师在 1 次时进行 FCSI 测试。
在基线时，STIF 组的犬只 FCSI 评分明显高于 OTHER 组和 CTRL 组（P<0.001）。仅在 STIF 组中，所有时间点的 FCSI 评分均有显著变化（P<0.001），表明该测试具有反应变化的能力。2 位测评者之间的差异无统计学意义（P=0.736），提示具有良好的测评者间信度，组内相关系数（ICC）为 0.78，介于中度至高度可信（0.78）之间。评估者进行 FCSI 测试时，在比较犬只组别时没有产生显著影响（P=0.214）。以组为单位的 ICC 置信区间分别为 STIF 组 0.79（0.60，0.91），OTHER 组 0.83（0.53，0.96），所有犬只组 0.78（0.64，0.88）。区分严重受损和轻度受损的临界值设定为 120，其具有 83%的敏感性和 89%的特异性。
FCSI 是一种推荐的犬膝关节功能评估方法。
