One third of the world population suffers from lower back pain. Why? Sitting for long periods of time causes lower back pain. A primary muscle that is affected by sitting is the psoas muscle. The psoas muscle lies deep in the stomach. It attaches at numerous low back vertebrae including L3, L4, L5, and S1. And it also attaches at the top of the thigh bone. When the psoas muscle tightens, it creates pressure on the discs of the low back. The L4, L5, S1 region gets squeezed and that pressure causes pain in the lower back.
Lower back pain causes
Psoas muscle tightness is almost always involved in lower back pain causes. And the prevalence of low back pain is extremely common because modern society requires humans to sit for long periods of time. We sit while driving, we sit at desks all day for work or school, and we sit while flying in airplanes. Ten hours a day of sitting everyday will cause low back pain.
Solution for lower back pain
The solution for lower back pain involves Active Isolated Stretching therapy. The AIS approach to lengthening the psoas involves a strong practitioner pulling apart the psoas muscle while the client lays face down on a massage table (see photos above). AIS has a self-stretching approach to lengthening the psoas. This self-applied stretch will help prevent a psoas muscle from tightening but it will not be enough to open an already tightened psoas muscle. Walking will help keep the psoas muscle open, but similarly, it will not open it enough if the psoas is contracted. Sitting creates six times more pressure on the discs of the low back than standing. Therefore, switching between sitting and standing will also help prevent/reduce low back pain.
