ABSTRACT
In the context of this book, among the numerous factors that cause low back pain, emphasis should be placed on chronic overuse of the lumbosacral area, which manifests itself in some occupations and in professional and nonprofessional athletes. For this reason, we are including cases of low back pain resulting from excessive chronic overuse of the lumbosacral area whose clinical picture corresponds to that of overuse syndromes. This includes some forms of spondylolysis and spondylolisthesis, low back pain in gymnasts, low back pain in some cases of scoliosis and kyphosis, and myofibrositis. Low back pain is the ailment of the century in modern, technological, highly advanced societies. Viewed from a statistical point of view, all adults suffer from low back pain at least three times in their life. This, of course, also implies that out of three adults, one will suffer nine times in his or her lifetime. According to some statistics, between 50 and 80% of the population in developed industrial countries suffers, or has suffered, from low back pain.
