“…It is noteworthy that in a study in which 17 showjumpers in a professional yard were assessed by the same clinician (S.D.) at rest, in hand, on the lunge and ridden, no horse had clinical evidence of thoracolumbar region pain, despite lameness or a positive flexion response in 15 horses (88.2%) (Dyson and Greve ). In the latter study, each horse used one of two saddles that had been assigned to it based on professionally‐assessed saddle‐fit every 6 months.…”

SummaryThere is limited knowledge about causes of musculoskeletal injury in showjumpers. The objectives were to describe features of the turn, approach and jump in a group of experienced showjumpers believed by their riders to be sound, to relate these findings to clinical findings, and to identify features that may predispose to injury. Ten experienced showjumpers in normal competition training jumped an upright and a parallel fence four times off the left and right reins respectively, after a rider-defined period of warm-up. Real-time and high-speed motion capture was undertaken. Detailed subjective assessment of the gait was performed during the warm-up, on the turn and approach to the jump and all phases of the jump. Six horses had thoracolumbar pain or epaxial muscle tension. Six horses exhibited a poor-quality canter. The mean duration of warmup was 7 min (range 5-10 min). All horses had lean of the trunk and hindlimbs >45°on the turn. The inside hindlimb was placed in front of the outside hindlimb in 75% of the turns. Sideways oscillations of the hocks during stance were seen in all horses on the turn and on the straight approach in five horses. The inside hindlimb had greater magnitude of oscillation than the outside hindlimb on the turns. Repeated asynchronous push-off with the hindlimbs at take-off was seen in three horses. The hindlimbs drifted to the left or right during the ascent-phase of suspension in four horses, reflecting asymmetrical push-off. Only two horses landed consistently with the correct forelimb leading relative to the direction in which the horse had to turn after the fence. Four horses landed seven (n = 2) or eight (n = 2) times each with the left (n = 2) and right (n = 2) forelimbs respectively. Repetitive overload through asymmetrical use of the left and right canter leads, inadequate warm-up, and limb instability could potentially predispose to injury.

“…This is representative for the sports horse population at large. Earlier studies have shown that a significant proportion of the sports horse population is not classified as completely sound or symmetrical, irrespective whether assessment is done subjectively by an experienced clinician (24) or evaluated by objective quantitative techniques (25). It is not known whether symmetry in lameness parameters correlate with back ROM in sound or well-performing horses, but if so, this could be an additional source of between-horse variation.…”

18 Clinical assessment of spinal motion in horses is part of many routine clinical exams but 19 remains highly subjective. A prerequisite for the quantification is the assessment of the 20 expected normal range of motion and variability of back kinematics. The aim of this study was 21 to objectively quantify spinal kinematics and between -measurement, -surface and -day 22 38 biomechanics are horse-specific and small, necessitating individual analysis and making 39 subjective clinical assessment of spinal kinematics challenging. 40 41

“…Dr Bathe and colleagues think that threshold values of inertial sensor systems must be 'surely redefined' because over half of 'normal' populations fall outside these reported thresholds. However, studies of subjective evaluation report similarly [19,20]. Should the way clinicians subjectively evaluate lameness be redefined?…”
