The spine is the switchboard of the entire body as it is responsible for flexibility and movement. Nerves run through the spinal column and when impinged by misalignment of the vertebrae performance is affected. Signs may include lameness, short striding, wrong leads, inablility to bend, heavy on the forehand and a change in overall disposition, to name a few. Horses will compensate, stressing out other muscles, joints and ligaments and this is why regular chiropractic maintenance is essential.
