One of our baseball players was trying to run out an infield squibbler & came up hobbling. The gracilis is often thought of as a adductor, which is true. But it is the only adductor that crosses the knee joint, which adds knee flexion/internal rotation into the mix. It is often mistaken for a hamstring strain because of it's location to the inside hamstring group. Be sure to differentiate this muscle from the hammies on your evaluation. Rehabilitation is different.
Because of it's origin on the pubis, the gracilis is not a hip extensor. Because of this fact, rehab that involves hip extension is usually tolerated early on. A step up for instance, as long as you begin/end in a narrow stance. So, the step up may be a good early phase way to "tweak out" the gracilis. In other words, it's being minimally recruited in a functionally appropriate manner.
OK, I've "tweaked out" in the sagittal plane. But we know the muscle also decelerates knee/hip abduction in the frontal plane. In the transverse plane, it decelerates knee external rotation. So, how might we functionally tweak out the other 2 planes? On to you guys.
