In this monograph, Alajouanine reviews an important group of cases in which the position of flexion obtains in the lower extremities. Paraplegia in flexion, he states, was first described by Ollivier d'Angers in 1837 in a case of dorsal Pott's disease. Vulpian, in 1879, and Charcot, in 1893, gave further descriptions of the condition. The cerebral type to which Alajouanine devotes his attention was described clinically by Brissaud, in 1880, by Demange, in 1883, and by Charcot, in 1893. Lhermitte in his monograph on senile paraplegias (1907) described the condition more completely.
Since in these cases the reflexes characteristic of spinal automatism are very evident, Alajouanine has investigated clinically, experimentally and pathologically the characteristics of both the spinal and cerebral form of paraplegia in flexion in order to determine whether a disorder of the same physiologic activities underlies both forms. He concludes that it does.
