A “striatal toe” (dystonic toe) is tonic extension of the great toe that occurs in extrapyramidal disease, particularly conditions affecting the striatum. It resembles the great toe extension of Babinski’s plantar sign but is tonic and sustained, not accompanied by fanning of the toes and occurs without plantar stimulation. The striatal toe has been referred to as the pseudo-Babinski sign. The extended toe may occur in isolation or as part of a foot dystonia that includes ankle inversion, arching of the sole and flexion of the other toes (striatal foot). In the Bajonet posture, the extension of the great toe occurs along with hyperflexion and hyperpronation of the hands and feet and is seen in some basal ganglia disorders.
