what is the normal range of lumbar rotation
Bending forward or rounding your lower back is called flexion. Flexion in the lumbar spine is primarily limited by compression of the intervertebral disks and tension in the ligaments that run along the back of the spine. The normal range of movement of lumbar flexion is 40 to 50 degrees.he range of motion, or how far your spine can move, is limited by the disks between the vertebrae, the ligaments that tie the vertebrae together and the orientation of the facet joints on the back part of the vertebrae. Muscle tension can restrict your range of motion as well.
The lumbar spine can side bend about 20 degrees each way. The spine in your lower back, called the lumbar spine, can bend forward, backward and side to side. It is capable of a small amount of rotation as well.he range of motion, or how far your spine can move, is limited by the disks between the vertebrae, the ligaments that tie the vertebrae together and the orientation of the facet joints on the back part of the vertebrae. Muscle tension can restrict your range of motion as well.
