Figure 6.

Primary right forelimb lameness. The vertical displacement curves of head and withers markers are displayed during one stride in the graph. During the sound diagonal stance (left fore [LF] – right hind [RH] diagonal limb pair), the horse reaches a lower vertical position for both, head and withers compared with the position during the lame diagonal stance where the lame right fore (RF) and left hind (LH) are weight bearing. Primary right hindlimb lameness. The vertical displacement curves of head, withers and pelvic markers are displayed during one stride in the graph. During stance phase of the lame diagonal (right hind [RH] – left fore [LF]), the head exhibits a lower vertical position during lame diagonal stance compared with sound diagonal stance. However, the withers and pelvic markers exhibit a higher vertical position during lame diagonal stance compared with the sound diagonal stance (left hind [LH] – right fore [RF]).
