A Ridden Horse Pain Ethogram (RHpE) was previously developed to facilitate the detection of musculoskeletal pain. The objectives were to apply the RHpE during warm-up for the dressage phase of two 5* three-day events and to correlate the RHpE scores with subsequent performance. It was hypothesised that there would be a higher rate of failure to complete the cross-country phase in horses which exhibited ≥7 behaviours compared with those showing <7 behaviours. The RHpE, comprising 24 behaviours, was applied for 10–12 min during warm-up. Gait abnormalities in trot and canter were recorded. Dressage penalties, cross-country performance, showjumping penalties and final placings were documented. Horses were categorised as those which completed cross-country, or those which did not complete because of elimination or retirement. RHpE scores (n = 137) ranged from 0 to 9/24 (median 3 [range 0–9] for nonlame horses; median 5 [range 1–9] for horses with gait abnormalities in trot or canter). There was a moderate correlation between dressage penalty scores and the RHpE score (rho = 0.4, P<0.001, Spearman rank). Fifty-nine per cent of horses (n = 10/17) with a RHpE score ≥7 failed to complete cross-country, compared with 33% (n = 39/117) with a score <7. Horses that failed to complete the cross-country phase had higher RHpE scores compared with those that completed (P = 0.04, W = 8.3, Kruskal–Wallis; pairwise comparison Bonferroni, P = 0.06). There was a significant (rho = 0.3) relationship between total RHpE score and final horse placings (n = 80, P<0.01, Spearman rank). Horses with lameness or gait abnormalities in canter had significantly higher RHpE scores (P<0.01, χ² = 35, chi-square test) compared with other horses. There was a strong correlation between the RHpE scores for horses which competed at both events (P<0.001, rho = 0.6, Spearman rank). The RHpE should facilitate earlier identification of horses which may benefit from diagnosis and treatment, resulting in improvement in both performance and equine welfare.

将骑马疼痛 Ethogram 应用于参加 5 星级三天赛事的马匹：与性能比较

以前开发了骑马疼痛 Ethogram (RHpE) 以促进肌肉骨骼疼痛的检测。目标是在两个为期 5 天的为期三天的盛装舞步阶段的热身阶段应用 RHpE，并将 RHpE 分数与随后的表现相关联。假设与表现出<7个行为的马相比，表现出≥7个行为的马完成越野阶段的失败率更高。包含 24 种行为的 RHpE 在热身期间应用了 10-12 分钟。记录小跑和慢跑的步态异常。盛装舞步处罚、越野赛表现、障碍赛处罚和最终名次都被记录在案。马被归类为完成越野赛的马，或因淘汰或退役而未完成的马。RHpE 评分 (n = 137) 范围为 0 至 9/24（非跛行马的中位数为 3 [范围 0-9]；小跑或慢跑步态异常的马的中位数为 5 [范围 1-9]）。盛装舞步罚分与 RHpE 分数之间存在中度相关性（rho = 0.4，P<0.001，Spearman 等级）。59% 的马 (n = 10/17) 的 RHpE 分数 ≥ 7 未能完成越野赛，相比之下，33% (n = 39/117) 的分数 <7。与完成越野赛的马相比，未能完成越野赛的马的 RHpE 得分更高（P = 0.04，59% 的马 (n = 10/17) 的 RHpE 分数 ≥ 7 未能完成越野赛，相比之下，33% (n = 39/117) 的分数 <7。与完成越野赛的马相比，未能完成越野赛的马的 RHpE 得分更高（P = 0.04，59% 的马 (n = 10/17) 的 RHpE 分数 ≥ 7 未能完成越野赛，相比之下，33% (n = 39/117) 的分数 <7。与完成越野赛的马相比，未能完成越野赛的马的 RHpE 得分更高（P = 0.04，W  = 8.3，克鲁斯卡尔-瓦利斯；成对比较 Bonferroni，P = 0.06）。总 RHpE 得分与最终马匹排名之间存在显着（rho = 0.3）关系（n = 80，P<0.01，Spearman 等级）。与其他马相比，慢跑时跛行或步态异常的马的 RHpE 评分显着更高（P<0.01，χ ²  = 35，卡方检验）。参加两项赛事的马的 RHpE 分数之间存在很强的相关性（P<0.001，rho = 0.6，Spearman 等级）。RHpE 应有助于及早识别可能受益于诊断和治疗的马匹，从而改善性能和马匹福利。
