How does hypermobility affect sports horse and why does stability and conditioning matter?
Hypermobility occurs when the structures that normally provide stability—such as ligaments, joint capsules, fascia, and muscles—allow excessive movement.
🟢 Increased joint range of motion
🟢 Reduced passive stability
🟢 Greater reliance on muscular control for support
🟢 Potential for inefficient force transfer
🟢 Increased risk of soft tissue strain and overuse injuries
I see this often in big young horses, often warmbloods but in many breeds. We have bred for big flashy movement. But this elasticity isn’t great for control! It’s our job as the people riding and caring for these horses, to do our best in their conditioning for stability and control, before ridden work starts, and throughout their careers.
As physios we often see young horses at vets with compensatory conditions from lack of strength and stability, that were expected to carry a rider and perform at levels they weren’t musculoskeletally ready for.
🟩Neuromotor Compensation: Because lax ligaments fail to provide passive joint stabilization, the central nervous system must adapt by planning alternative muscle recruitment strategies (McGowan et al., 2007). Deep, local stabilizing muscle groups must work continuously to modulate joint stiffness.
🟩Risk of Secondary Pathology: If the muscular system is weak or fatigued, hypermobile joints are subjected to erratic mechanical loads. This frequently results in early-onset osteoarthritis, compensational back pain (such as desmopathy of the supraspinous or intraspinous ligaments), and unrecognized low-grade lameness (Domańska-Kruppa et al., 2024; McGowan et al., 2007).
How can we help these horses? Slow structured VARIED conditioning, multiple surfaces and gradients, movement with intent! Focusing on whether they can balance, and control their limbs effectively with and without a rider. Not moving on to the next stage of training until the horse has mastered balance and control in this one!
