What is neurogenic claudication? I've heard the term and know that my mother's doctor told her that's what is causing her back pain.

The word neurogenic simply refers to nerves, implying the the problem is nerve-related. Claudication means limping. Some people who limp also have leg pain or cramping discomfort in the calf, so they think claudication refers to their pain. They will be half right because what they usually have is limping from pain or discomfort.

There are different kinds of claudication. Each one is named for the underlying cause. For example, if blood circulation is cut off to the lower leg because of clogged arteries, the patient has vascular claudication.

Vascular claudication comes on with activity when the heart is asked to deliver more oxygen to the legs. But the blood can't get past the clogged arteries. Pain or discomfort from a lack of blood occurs. As might be expected, vascular claudication goes away by stopping the activity (standing still) or with rest.

Spinal or neurogenic claudication is not due to lack of blood supply. It is the same kind of pain caused by nerve root compression, usually from a degenerative spine.

This type of claudication is often relieved by rest but position is even more important. Any position that puts pressure on the spinal nerve(s) will increase the painful symptoms. And a change in position to relieve the pressure can reduce the symptoms. Bending forward usually reduces the symptoms of neurogenic claudication. Standing up straight or extending the spine makes the symptoms worse.
