This'erect position of the body and head is always accompanied with straight lower limbs. Fig. 91. I. A perpendicular line from the centre of the feet. 2. Rep- resents the unnatural curved spinal column and its relative position to the perpendicular, (!.) The lower limbs are curved at the knee, and the, body is stooping forward. While standing in this position, the muscles of the lower limbs and back are in continued tension, which exhausts and weakens them.
