This is great, but increases the chances that more owners will encounter back problems with their horses. Horses can certainly fall or become cast in a stall, therefore causing primary damage to their backs. This type of problem is easier to diagnose, because when you turn your horse out or put it in for the night, the horses fine. The next day your horse is sore or lame. This is not typical, however.
Back problems are often chronic and low-grade and almost always bring a reduction in performance.
The original cause of most back problems has to do with something other than the back itself. Horses will try to compensate for problems or minor injuries and often alter the way they move. They will continue to work and perform and the change in movement can be so subtle that even experienced riders don't always notice it at first. This is the case with most back problems in horses. Everything from arthritis to poor shoeing or foot care to unbalanced riding and an ill-fitting saddle can contribute to secondary back soreness.
