WEEK 19 Iliopsoas, on the ground training and tweaking for success

This week was full of new information and concepts. We had been trained as therapists to “train the way you play” i.e. if you perform in an upright position, you should train in an upright position. The Gray Institute has looked closer at on the ground training, and thinks we are missing a key to using  the bodies natural developmental stages, in the first year of life, to assist in upright function.

We can look at the Transformation Zone of  upright function and decide what would assist with on the ground function. We can use  a variety of start positions such as prone, supine, side ly, and kneeling, with manipulations of these positions. Then use drivers of the head, trunk, hands, pelvis, and feet to move the body for greater mostablity.

The muscle discussed this week was the Iliopsoas. It is the muscle called on in emergencies and is responsible for swinging the leg and body through from toe off to heel strike in gait. It has connection to the transverse processes of L1-L5 and vetebral bodies of T12-L4. This muscle is loaded significanlty with transverse plane motion (internal hip rotation), but also extension, Abduction (Psoas muscle) and Adduction (Iliacus muscle) of the hip. Even if the hip is flexed it’s transverse and fontal plane loading has an important part to play in function.

At the spinal level, rotation of the spine can load the Iliopsoas, depending where the spine is relative to neutral. In the front leg of gait it is unclear of the Iliopsoas decelerates lumbar rotation or rotates it in the same direction as the pelvis. The iliopsoas will decelerate contralateral Lumbar lateral flexion.

Remember AFS is.. encourage transformation in others through the creation of personalised environments, using drivers, to create normal chain reaction through the body. If we can choose the correct drivers to load the Iliopsoas, we can create the explosive power we need it to produce for function.

Finally we looked more at tweaking the body for success. If we can choose the degree of tweaks (subtle to dramatic) which encourage the desired change reaction in the body, we can become more effective at attaining success. We looked at using bilateral symmetrical and assymetrical hand drivers, and then whether to use them in an alternating fashion. We looked at the power of the pelvis as a driver and how this is often the key driver in function.

We are starting to learn more about the spine and the muscles influencing the spine. I look forward to enhancing my knowledge of chain reaction biomechanics through spine and then the shoulder girdle.
