Sequence of joint movements of the lower limb to evoke radicular pain in people with lumbosciatica

Abstract

Introduction. Lumbosciatica, a painful condition that affects the lumbar region, is recognized by the WHO as a global health problem. It is classified as acute, subacute, and chronic, impacting the quality of life of patients. The excursion of the sciatic nerve, linked to neurobiomechanics, influences the appearance of radicular pain. Objetive. To analyze the sequence of movements of the lower extremities to evoke radicular pain in people with lumbosciatica, considering the neurobiomechanics and diagnostic accuracy of the tests. Methodology. A systematic review was conducted on the neurobiomechanics of the sciatic nerve during lower extremity movements and diagnostic accuracy in cases of radicular pain. Results. 132 studies were examined, with 6 selected for review. Conclusion. The study highlights the influence of the sequence of movements on radicular pain, especially with dorsiflexion. Tests such as Slump and others are useful in evaluating lumbosacral injuries and it is recommended that additional movements be explored in future research.
