How do horses move?

Each limb has bundles of nerve cells called Central Pattern Generators that control limb movement. There are forelimb CPGs in the cervical (neck) region and hindlimb CPGs in the lumbar region.

CPGs can function independently to create cyclical movement patterns, they don’t actually require sensory input from the limbs or instruction from the brain.

However they can respond to both so they can modify movement according to information from the limbs or the brain, for example if the surface underfoot changes, or if the horse suffers an injury, the CPGs would respond to this change and alter the way the horse moves.
