The radiological changes in asymptomatic ones, the lack of symptoms in the control group, the presence of chronic and acute features and the discrepancies in the prevalence of low back pain were attributed to the existence of an anatomic and functional reserve. This reserve would be determined by the presence of a "safety factor" which would have differential distribution in asymptomatics, acute and chronic. It would be the element able to influence the presence or absence of low back pain in persons with radiological changes.
