Summary
# Editorial Summary Pelvic control has emerged as a key factor in rider effectiveness, yet its relationship to actual postural stability and horse-rider synchronicity remained poorly understood in dressage populations. Walker and colleagues examined 26 amateur to advanced dressage riders on their own horses, stratifying them by their ability to perform controlled pelvic tilt on a Swiss ball—a proxy measure for isolated pelvic mobility—then analysing high-speed motion-capture footage during collected trot to assess rider position, symmetry, and temporal synchronisation with their horse's movement. Riders lacking adequate pelvic control (those compensating with major lumbar or trunk movement) demonstrated significantly greater forward lean, increased left-right asymmetry, and greater phase lag during the swing and stance phases of the trot; conversely, those with better pelvic control showed improved postural alignment and more coordinated movement with their horses. The practical implication is substantial: farriers, vets and coaches working with riders should recognise that apparent positional faults—forward lean, asymmetry, or loss of synchronisation—may stem from fundamental deficits in isolated pelvic mobility rather than simply poor riding technique, suggesting that core stability work addressing pelvic control could meaningfully improve both rider position and the mechanical demands placed upon the horse.

Practical Takeaways
- •Pelvic stability and tilt control are foundational skills; assess your own ability to isolate pelvic movement without compensating through the lumbar spine or torso lean
- •Poor pelvic control manifests as asymmetrical riding position and loss of synchronicity with the horse—both undermine dressage performance and may contribute to repetitive strain
- •Training pelvic stability off the horse (e.g., Swiss ball work) may improve on-horse postural symmetry and timing, particularly relevant for riders competing above Novice level
Key Findings
- •No riders could perform anterior or posterior pelvic tilt on a Swiss ball without compensatory movements (lumbar spine inclusion or forward/backward lean)
- •Riders with poor pelvic control demonstrated more forward-leaning posture compared to those with better control
- •Riders with major pelvic compensation showed greater left-right postural asymmetry during sitting trot
- •Reduced pelvic control correlated with increased phase shift between rider and horse during swing and stance phases of trot
