Note the accentuated anterior pelvic tilt and lumbar lordosis producing a swayback posture, the marked atrophy of the leg muscles, and the back-kneeing (genu recurvatum). The images are from Plate 539 in Muybridge’s Animal Locomotion (Muybridge E. Animal locomotion: an electrophotographic investigation of consecutive phases of animal movements, 1872-1885. Philadelphia: University of Pennsylvania, 1887). The boy was photographed by English-American photographer Eadweard Muybridge (1830-1904) and Francis Xavier Dercum (1856-1931) in 1885.
