A gentleman came to see us recently experiencing L side sciatic discomfort that over the years had come and gone and had recently come back. He had a fairly typical history of a couple of sprained ankles, L side SI joint discomfort and most interestingly a restriction in his R shoulder which also had a couple of bone spurs that at some point will require an operation. We identified a couple of things going on in his L leg and hip that were contributing to the sciatica but it also turned out that his R shoulder was involved!
The posterior oblique sling comprises, simply, of the R latissimus dorsi (a big powerful back muscle), the thoraco-lumbar fascia, and the L side glute (the big backside muscle). It turned out that due to his restricted shoulder mobility this sling had been compromised and that the sciatica was a result of some smaller hip muscles trying to do the job of the glute that was unable to function properly which were pinching on the sciatic nerve.
By working on his R shoulder not only were we able to resolve the sciatic symptoms but gained greater R shoulder mobility than he had for years! This gentleman will likely have to his homework in an ongoing manner due to the structural problem in his R shoulder but who knows, giving back this mobility may also offset surgery for a few more years.
