Most people have seen a tensegrity model. These are clever constructions of sticks and elastic that use balanced tension and compression to created self supporting shapes.

It is possible to consider the body as a tensegrity model, where the bones, muscles and ligaments all act together to support, articulate and move.

Although simplistic and missing huge elements of the effects of fascia, organs, inflammation and so forth, it is a useful analogy to hold, especially when trying to educate patients.

Recently, I have been considering the lumbar spine and the need for good abdominal support around it. The metaphor I use it that of a wobbly stick attempting to link upper and lower halves of the body. The pelvis is a fairly stable, solid object and the thoracic spine is well held with the ribs. This leaves the cervical spine (a wobbly stick with a block on top) and Lumbar spine to do a lot of work. Therefore, we need plenty of active muscles recruited to provide stability, support and movement.

So, no matter how much we may train that six pack and work to get well toned abs, if we cannot recruit them during activity, its fairly pointless.

I have 3 basic exercises I start with for every patient and, if they can do those, move to the next level. These are:

Pelvic control: The patient lies supine, slides one heel up the couch or floor, whilst attempting to maintain a level pelvis, the ASIS not deviating significantly posteriorly. Recruitment of the TA is particularly useful in this.

Cat crunches: On all 4s, the patient pulls their navel towards the spine, attempting to keep everything else still. A count of 5 and release slowly. This helps recruit deep obliques and the thoracolumbar fascia attachments.

Gluteal raises (trendelenburg drops). The patient stands sideways on a step and allows one leg to drop. They raise it back up again, using the opposite glutes, minimising recruitment of QL or lumbar erector spinae if possible.

Once they’ve got these, then the neuromuscular paths are working better and we can progress to more dynamic tests.

No more wobbly stick, less back pain.
