the basic movements involved in walking are (1) flexion and extension at the hip, knee, and ankle joints and at the front part of the foot; (2) abduction and adduction, chiefly at the hip joint; and (3) rotation, mainly at the hip and knee joints. when there is damage at one or all of the above, the body its natural defense is to take weight off of that area which not only alters gait but increase load to another area of the body.
