Babinskis Trunk-Thigh Test
Babinski’s Trunk-Thigh Test
Babinski’s trunk-thigh test is suggested to be of use in distinguishing organic from functional paraplegia and hemiplegia (Hoover’s sign may also be of use in the latter case). The recumbent patient is asked to sit up with the arms folded on the front of the chest. In organic hemiplegia there is involuntary flexion of the paretic leg; in paraplegia both legs are involuntarily raised. In functional paraplegic weakness neither leg is raised, and in functional hemiplegia only the normal leg is raised.
