Hurt your back shoveling snow after last week’s epic snow storm? Back pain develops for many reasons, including lifestyle, genetics, ergonomics, sports injuries, or unknown reasons. If we begin and stick with an exercise program, we might avoid a recurrence, according to a new comprehensive scientific review of back pain prevention. The study concluded that if someone with a history of back pain exercised in a regular way, he or she was considerably less likely to be felled by more back pain within a year. Of all the therapies that are available for back pain, exercise is the only one with consistent evidence that it works. While we still need more research to determine if one type of exercise program is measurably better than others, it has once again been confirmed- exercise helps.
