Pelvic Placement

PELVIC PLACEMENT PRINCIPLE EXPLAINED

STOTT PILATES emphasizes stabilization of the pelvis and lumbar spine in a variety of positions. Two positions most often used to achieve stability are neutral and imprint.

In neutral placement the normal curve, slightly convex anteriorly, of the lumbar spine is present. In most cases when supine, the triangle formed by the ASIS and the symphysis pubis should lie parallel to the mat. This is the most stable and optimal shock-absorbing position and a good place from which to promote efficient movement patterns. If the pubic bone is lower than the ASIS, an anterior pelvic tilt results; if the pubic bone is higher, a posterior pelvic tilt results.

Neutral alignment should not be achieved by forcibly arching the back, but rather by allowing the weight of the sacrum to rest on the mat resulting in a natural lordosis of the lumbar spine. While breathing and engaging abdominals in this position no strain should be felt through the spinal extensors in the lumbar area. If muscular tension occurs, shift the pelvis slightly toward an imprinted position. It is more important for the abdominal wall to be engaged and the lumbar area to be stable and unstrained than for the ASIS and pubis symphysis to lie in the same horizontal plane. For example, someone with large gluteal muscles might actually create an exaggerated lordosis in the lumbar spine by trying to have the ASIS and pubic bone lie in the same plane.

Imprinted placement refers to a slight posterior pelvic tilt with slight lumbar flexion. The normal curve of the lumbar spine lengthens toward flexion by engaging the oblique abdominals to approximate the pelvis toward the rib cage anteriorly.

When supine, the pubic bone will be slightly higher than the ASIS. The pelvis is not so tilted that the sacrum curls off or loses contact with the mat. It is not necessary to press the lower back all the way into the mat or to tuck under by overusing the rectus abdominis or gluteal muscles as this may decrease stability. The degree of contact between the lumbar spine and the mat will differ from person to person.

An imprinted position should be used to ensure stability of the pelvis and lumbar spine if neutral alignment cannot be stabilized. When the load is greater than the strength of the abdominals, placing them in a shortened position will provide the mechanical advantage to maintain engagement and stabilize the lumbo-pelvic region. This will often be useful when certain postural tendencies are present (for example, lordosis). When the lower limbs are secure on the mat or other apparatus in a closed kinetic chain, the pelvis and spine are ideally neutral. Performing an open kinetic chain exercise with the pelvis and lumbar spine in an imprinted position will increase stabilization. Once enough strength has been developed through the abdominals to stabilize, a neutral placement can be maintained in an open kinetic chain.

When describing the position and movement of the pelvis, we use neutral to refer to the spine or pelvis being neutral in the sagittal plane, i.e. no flexion or extension through the lumbar spine. Sometimes we may be laterally tilting the pelvis or laterally flexing or rotating the spine, but we still refer to the spine and pelvis as neutral as long as they are neutral in the sagittal plane.

When looking at pelvic placement, we need to consider the relationship of the pelvis to the lumbar spine and hip joints, as different starting positions and movements will affect its alignment.

Pelvic Placement

Scapular Movement & Stabilization

SCAPULAR MOVEMENT & STABILIZATION

PRINCIPLE EXPLAINED

Stabilizing the scapulae (shoulder blades) on the rib cage is extremely important as they serve as an anchor for the arms as well as support the cervical spine. When this is not done, there is a tendency to overwork the muscles around the neck and shoulders.

Be aware of scapular stabilization at all times: a) when the spine is neutral and the arms are resting; b) when the spine is flexing or extending; c) when the arms are moving in any direction. Due to the lack of direct bony attachment to the rib cage and spine, the scapulae have a great deal of mobility. In making a greater range of motion available to the arms, the scapulae can glide upward (elevation), downward (depression), inward (retraction) and outward (protraction), can rotate upward or downward, or perform any combination of the above.

Through the whole shoulder girdle, a sense of stability, not rigidity, should always be maintained. A sense of width should be maintained

The shoulders should not be allowed to give in to excessive movements. The scapulae should lie flat on the rib cage and glide across it without winging markedly (this refers to the medial border of the scapulae coming away from the rib cage). Keep in mind that the scapulae will react to movements of the arms and thoracic spine. For example, the scapulae will naturally elevate and upwardly rotate during overhead movements and protract during thoracic flexion.

Be aware that a neutral placement of the scapulae may be slightly different from a particular individual’s natural resting position. An ideal working alignment must be established for each individual. Scapular stabilization should be part of the initiation of all exercises, and established before the movement of exercise begins. When flexing the torso off the mat from a supine position, scapular stabilization will discourage neck tension and excessive protraction of the scapulae and medial rotation of the humeri. Spinal extension should be initiated with stabilization of the scapulae while reaching the top of the head away from the tailbone. This limits the tendency to over-exaggerate movements and decrease dynamic stability through the whole upper kinetic chain.

Throughout this manual, when describing the exercises, we will refer to the scapular stabilizers collectively rather than naming individual muscles. The focus is on serratus anterior, trapezius, rhomboids, levator scapulae and pectoralis minor.
