Horses suffering from back pain require correct rehabilitation that focuses on strengthening and stabilization regardless of the source of the discomfort. Hilary Clayton, BVMS, PhD Dipl. ACVSMR, FRCVS, professor and McPhail Dressage Chair Emerita in Michigan State University, in East Lansing, described the objectives and exercises to help in the rehabilitation of horses from back discomfort at the 2022 British Equine Veterinary Association Congress that was held from September. 7-10, in Liverpool.

Clayton said that one of the primary steps to be taken in the rehabilitation process is to activate the muscles that stabilize deep. “The exercises that I particularly like (for for this) are the exercises for dynamic mobilization, or stretches with bait,” she said. “The basis of this is that the horse is trained to obey a reward using his nose and allows the handler to place the neck and head in various postures. This is not just beneficial for spinal mobility, but also tests the horse’s ability to balance in various situations.”

She described a variety of exercises for rounding, such as chest to chin as well as the chin between the carpi (knees) as well as chins between the fetlocks as well as lateral bend exercises, like chin-to-girth as well as chin to stifle and chin to the hind fetlock. “The more or less back the horse is positioned during these stretches the greater the poll’s angle is opened and the greater angles at the neck’s base is bent or flexes,” Clayton added. The practice of stretches with baited every week, with five repetitions of each stretch every day, increases your deep stabilizer spinal muscles, and enhances their symmetry from left and right sides within six weeks, according to Clayton.

The trainer also said that while she recommends slow feeders, horse owners should steer clear of haynets as well as other methods of feeding that are high. Instead, opt for slow feeders that require horses to keep their neck and head in a lower position.

Trainers and owners can improve stability by performing exercises that move your center of mass to the base of support of the horse that triggers an increase in stability within the muscle. The exercises that can be used include:

  • The tail should be pulled gently to the side, thereby activating the hip stabilizers and to stifle.
  • Reduce the dimensions of the support’s base by taking a leg, and then gently pushing the body of the horse
  • The horse is positioned on the slippery surfaces.
  • Stabilizing the horse’s balance through shifting limbs during the swing phase using pole exercises.

“The purpose is to stimulate the horse to use his spinal and muscle groups that stabilize the limb,” said Clayton.

“Many activities used for rehabbing back discomfort can be completed in a walk or halt however, we will eventually get to an age where it’s essential to incorporate trots as well as the canter in the rehabilitation program.” Then, we must think about which is the less harmful of the two alternatives? The longe being ridden or incorporating an extra weight to the rider?”

When you introduce longeing to your rehabilitation program, it’s ideal to start with a big circle and slower speed. The horse must be permitted to lean backwards on the circle in order to create the ground reaction force that turns, Clayton said.

“The riding weight of the horse can increase flexion of the lumbosacral joint when in stance as well as in the motion of riding,” she explained. “As consequently that the horse’s back drops downwards towards the croup. Thoracolumbar sagging corresponds directly to the mass of the rider, therefore it is logical to start with a light, small rider.”

As the horse progresses through his rehabilitation, exercises must be added to increase strength and coordination, as well as engage the muscles that are mobilizing the core. Hillwork is a good exercise to introduce slowly beginning with the walk, later when trotting and canter. On an upslope the force of gravity on the hind limbs of the body and increases the strength of muscles of the back, including back musclesand gluteals and hamstrings, as well as activating the abdominal obliques that are located inside to help stabilize the trunk. In a downward slope gravity swells the forelimbs more than it does on the flat, which can increase the risk of concussive injury. Clayton recommends taking gradual, controlled movements and in a good self-carriage. This strengthens the thoracic sling muscles as well as activates the abdominal oblique and external abdominal muscles that control the trunk’s rotation.
