One of the main causes of back pain is too much sitting. We often see patients who are experiencing intense back pain. This pain usually starts from their low back and travels down their leg into the calf muscle. By the time they reach our clinic, many of them have performed a Google search, and self-diagnose themselves as having sciatica.
Luckily, sciatica is not usually the reason for their back pain.
Sciatica is a term used to describe pain traveling from the low back, to the glutes, and into the back of the legs. The term sciatica devries from the name of the sciatic nerve. As you can see in the picture to the right, the sciatic nerve travels from the low back, through the buttocks and down the leg. When this nerve is pinched, either by a bulged or herniated disc, the sciatic nerve can be compressed, causing nerve-like pain down the leg. As you can imagine, this pain is quite debilitating and painful.
What most people experience in the clinic is not sciatic pain, but pain caused by too much sitting. When you sit, your gluteal muscles, hamstrings and calf muscles have to shorten to allow your knee to bend over the chair. Over time these muscles can shorten, especially if they are not stretched regularly.
You can check to see how tight your muscles are by performing a straight leg test. Simply lay on the floor and bring your leg straight up without bending the knee. If you can bring the leg up to 90 degrees, you have good hamstring flexibility. The back pain patients that I see can only flex their leg to about 30-40 degrees (less than half than normal). Their tight hamstring and calf muscles are limiting the range of the leg, as they have shortened due to excess sitting.
Tight muscles can not only reduce your flexibility, they can also ‘tighten’ the joints of the spine, particularly the low back and pelvic joints. In the picture to the right, the areas marked in red can become restricted. Chiropractic care can help unlock these joints, which can help improve flexibility.
