FIGURE 5.18. Bilateral leg lowering. Begun in week 9, this exercise requires a good deal of attention and guidance on behalf of the therapist or athletic trainer. The athlete begins lying in supine with hips flexed to 90 degrees and knees extended (A). Pelvic stabilization via the drawn in umbilicus should be used and maintained throughout the following movement. From this position, the legs are lowered by eccentric contraction of the hip flexors to a point at which the pelvis begins to tilt anteriorly (B). This anterior tilt signifies the inability of the abdominals to isometrically stabilize the pelvis any further. Immediately at this point the legs are slowly brought back up to 90 degrees of hip flexion. As abdominal strength increases, the athlete should be able to lower his or her legs further toward the floor before allowing an anterior tilt and having to raise them to their starting position.
