Functional anatomy of the lower limb.
To understand the functional anatomy of the lower limb, one must apply one's knowledge of the gross anatomy to the gait cycle. Gait analysis then leads to a better understanding of the function and dysfunction seen in the lower limb. Data from biochemical studies help one appreciate the forces the major joints are subjected to. These loads are three to five times body weight. The reason normal gait is so smooth is that there is minimal motion of the center of gravity located in the pelvis. Supple joints and good muscle strength are needed or gait disturbances result.
