The plate shows in ten consecutive pictures taken back-to-back the quite typical method of transition from the recumbent to the vertical pose for this disease type.
As one can see, at first the recumbent body wallows on its side, always underpinned, from the point of hoisting up the upper body by the elbows, then after at the stretching of the arms by the hands. And now follows a complete rotation of the body to the ventral side, then knee bend and supporting of the body on hands and knees. Hoisting up to the feet comes afterwards, the knees stretched underneath, and now the upper body struggles to an upright stance, by an under wrangling, teetering movement of the trunk, the arms drawing themselves ever higher up the legs, and so in this way allowing the body to ratchet aloft. Finally, the boy displayed in an upright position, the figure demonstrates the significant lordose of the lower thoracic and pelvic vertebrates conditional to atrophy of the waist and back areas.
7 year old boy, parents not nervously debilitated. Among the siblings is an older sister sickened in a similar way, the rest healthy. the boy has had neither acute exanthema nor other infectious diseases. The boy learned to walk at the proper time, but could never run or jump.
