Until an injury occurs, many people fail to realize exactly how much they use the muscles in their lower back. An individual's back is engaged and necessary for nearly every movement and certainly any that involves walking or lifting. Even sitting can cause an individual's back to become strained and ache. In cases where an individual strains, pulls or tears the muscles in his or her back, it can be difficult to perform simple everyday tasks much less work.
Chronic pain not only affects an individual's physical health but can also have psychological effects. Experiencing pain day in and out is tiring and may prevent an individual from being able to participate in activities he or she previously enjoyed as well as work. Two new studies that examined the prevalence of lower back injuries amongst people around the world and amongst workers in various industries were recently published in the Annals of the Rheumatic Diseases.
