Hip Mobility

Kneeling Lunge

The hip is simple in it's joint configuration, but very complex in its function.  Like the shoulder, it is a ball and socket joint.  That means that the thigh bone has a spherical head (femoral head) that fits into a cup-like socket (acetabulum) of the pelvis.  This type of joint offers high freedom of motion to allow us to get down into a squat, high kick, dance, karate, etc.  Compared to the shoulder, the hip has a little less motion in order to provide stability, and the femoral head can sit deeper in the socket of the acetabulum in order to prevent dislocation.
Because the hip is ball and socket, the joint is multi-axial, meaning it can move in many many planes of motion. When the foot is not touching ground (open chain) these actions are:

• Abduction- moving the thigh away from midline
• Adduction- moving the thigh toward the midline
• Flexion- moving the thigh toward the chest
• Extension- moving the thigh toward the back
• Internal Rotation/External rotation- rotation about the femoral axis
• Circumduction- moving the joint in a full circle

As I mentioned above, the joint is simple, but the function is complex because the hip joint, like any other joint in the body, does not work/move in isolation.  Lack of hip range of motion can effect the health of the shoulders, spine, pelvis, knees and feet.  Improving hip joint motion is one of the key steps to ensure proper mechanics of the extremities and the spine.  How are your hips?  Try these moves for better movement.
