Common symptoms of affected SI-joint
How the horse can react when asymmetric and affected in the Sacro-Iliac-joint
Sacro-Iliac-joint-problems can show in many ways, depending on how the horse is used and the horse's general health.
All of the horses though, will try to avoid loading and maximum stretching of the hind-bone (forwards and backwards) on the affected side. That is: when the pelvis is to be included in the movement of the hindleg, it activates the pain.
This is a list of the most common symptoms I find among the affected horses. The horse can show one or several of them.
The horse does not stand equally on all four legs. Usually it puts more weight on the frontlegs and the hindlegs under the abdomen. It could also stand with his back lowered and the hindlegs far behind.
Difficulties in shoeing the horse, especially the hindlegs
The horse cannot build the right muscles, and looks uneven from behind
The horse has low energy from behind, lack of impulsion from one or both of the hindlegs
The horse put a lot of weight in the hands of the rider
Difficulties in bending on one rein, bending over on the other
Taking the bit
Changing hindleg often while resting
Stubborn or hot tempered
Decreased action of the back when jumping, hindlegs tilted to one side
Mild lameness in front and/or hindlegs, periodically
Shorter stride on one of the hindlegs in walk
Asymmetric seen from behind
Icelandic horses also: Pacy/ trottlike tolt
"Rolling" in tolt
Trotters also: Uneven beat in trot
Restriction in action
Gait disturbances in curve or at a straight line
Dragging the toe of one hindlimb
Tendency to take gallop-steps
Hanging on one rein
