In the sport of dressage, one or more judges score the combined performance of a horse and rider with an emphasis on the technical correctness of the movements performed. At the end of the test, a single score is awarded for the 'general impression', which considers the overall performance of the horse and rider as a team. This study explored original measures that contributed to the general impression score in a group of 20 horse-rider combinations. Horses and riders were equipped with inertial measurement units (200 Hz) to represent the angular motion of a horse's back and the motions of a rider's pelvis and trunk. Each combination performed a standard dressage test that was recorded to video. Sections of the video were identified for straight-line movements. The videos were analyzed by two or three judges. Four components were scored separately: gaits of the horse, rider posture, effectiveness of aids, and harmony with the horse. The main contributor to the score for gaits was stride frequency (R = -0.252, = 0.015), with a slower frequency being preferred. Higher rider component scores were associated with more symmetrical transverse-plane trunk motion, indicating that this original measure is the most useful predictor of rider performance.
在盛装舞步运动中，一名或多名裁判对马匹和骑手的综合表现进行评分，重点在于所完成动作的技术正确性。在测试结束时，会根据“总体印象”给出一个单一分数，该分数考量的是马匹和骑手作为一个团队的整体表现。本研究探究了在一组20对人马组合中对总体印象分数有贡献的原始测量指标。马匹和骑手配备了惯性测量单元（200赫兹），以呈现马背部的角运动以及骑手骨盆和躯干的运动。每对组合都进行了一次标准盛装舞步测试，并录制了视频。从视频中识别出直线运动的部分。由两到三名裁判对视频进行分析。分别对四个部分进行评分：马的步态、骑手姿势、辅助动作的有效性以及与马的协调性。对步态分数的主要贡献因素是步频（R = -0.252，P = 0.015），频率较慢更受青睐。骑手部分的得分越高与横向平面上更对称的躯干运动相关，这表明这一原始测量指标是骑手表现最有用的预测指标。
