One topic that seems to have gotten a resurgence of popularity lately is something termed “joint centration” by Dr. Evan Oscar. Joint centration is simply the act of keeping the joint aligned in the correct position throughout a joint’s range of motion. This will help keep the joint healthy and in the case of the hip, may help to prevent impingement herunterladen. You can read more about this in Dr. Evan Oscar’s book, “Corrective Exercise Solutions to Common Hip and Shoulder Dysfunction.”
As previously stated, the hip is a ball and socket joint. The ball portion is known as the femoral head and the socket is known as the acetabulum. In the bottom position of the squat the femoral head is normally supposed to glide posteriorly into the back of the acetabulum powerpoint kostenlosen windows 10. The femoral head does the opposite as we come to the top position of a squat. A balance between muscles helps us to achieve this.
If we have a muscular imbalance or a tightness in the posterior aspect of the hip the femoral head won’t be able to glide posteriorly the way it’s supposed to when we get to the bottom of the squat. If the femoral head doesn’t glide posteriorly adequately or it glides anteriorly as we hit the bottom of the squat then we’re bringing the femoral head closer to the front of the acetabulum. If these two structures collide, we’ve got impingement. Down the line we might have a labral tear.
Dr herunterladen. Shirley Sahrmann, a world reknowned physical therapist, has identified a condition she calls Femoral Anterior Glide Syndrome (FAGS). In this syndrome, the ball portion of the joint ends up gliding anteriorly and internally rotating both as you flex and extend your hip.
As discussed previously, if our femoral head doesn’t glide properly during squatting we’re going to cause femoral acetabular impingement. These patients also present with groin pain, which is a classic sign of hip pathology!
Sahrmann states that the main culprits for this are:
A solution to this problem is going to consist of stretching the posterior capsule and tissues that cross the back of the hip as well as picking exercises to preferentially target the glute max without activating the TFL.
Fortunately for us. The Journal of Sports and Orthpaedic Physical Therapy (JOSPT) recently released an article that did an EMG analysis to find the best exercises to target the glutes and minimize the TFL. Check the photo to the left for the top 5 exercises.
An interesting side note: Lunges and step-ups caused quite a bit of TFL activation. Squats were a better exercise but not as good as these 5
The next step is to go ahead and stretch the hip posterior capsule and any tight muscles and tissues that cross over the back of the hip. Here are a few of my favorite stretches:
For the stretch below you can rest your bottom foot against a wall for a better stretch.
There you have it guys. That’s all I have for you today. Next time we’ll wrap it up and figure out our final game plan for dealing with these pinchy hips.
My hips feel much better,
