Lower back pain is defined as the presence of pain, with or without stiffness, located in the lower region of the spine, between the last costal arch and the gluteal fold. In the elderly, inherent factors of aging, such as inactivity, postural instability and a decrease in neuromuscular response, contribute to its occurrence. Although studies have pointed to a reduction in prevalence in this population, when the severe forms of lower back pain are analyzed, there is a significant increase.
