As in other regions of the spine, the movements of the lumbar spine are flexion, extension, lateral bending, and rotation. While lumbar motion is potentially greater than that of the thoracic spine because of the lack of rib restriction, facet facing and heavy ligaments check the range of rotatory motion.
What ranges of motion are possible at the lumbar spine?
Motion of the lumbar spine occurs in 3 planes and includes 4 directions, as follows:
- Forward flexion: 40-60°
- Extension: 20-35°
- Lateral flexion/side bending (left and right): 15-20°
- Rotation (left and right): 3-18°
What are the movements of the lumbar spine?
Biomechanics of the lumbar spine and sacrum (L4-L5 L5-S1)
The 3 movements in the spine are flexion, extension, rotation and lateral flexion. These movements occur as a combination of rotation and translation in the following 3 planes of motion: sagittal, coronal and horizontal.
What movement is most limited in the lumbar spine?
Mobility of the lumbar spine (Fig. 3) is greatest during flexion/extension movements (cumulative mobility in segments L1-5: 57°) and more limited during lateral bending (L1-5: 26°) and axial rotation (L1-5: 8°) (31).
What is normal flexion of the lumbar spine?
Lumbar Spine Range of Motion:
|Left Lat Flex||25|
|Right Lat Flex||25|
What movement is reduced in the lumbar spine?
Lumbar spine side bending is reduced in end range extension compared to neutral and end range flexion postures. Man Ther. 2014 Apr;19(2):114-8. doi: 10.1016/j.
What part of the spine controls what part of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What muscles attach to the lumbar spine?
Lumbar vertebrae provide attachment points for numerous muscles: erector spinae, interspinales, intertransversarii, latissimus dorsi, rotatores, and serratus posterior inferior.
What aggravates facet joint pain?
Pain is often aggravated by leaning back (extension) and/or twisting (rotation) of the neck or back, and can be relieved by bending forward (flexion). Cervical facet pain can cause pain when turning the head while driving or difficulty at night relaxing the neck when lying down.
What is lumbar spine flexion?
Flexion is the anatomical name for forward bending. When treating back pain, many spine specialists encourage exercises to strengthen the muscles that act to bring the spine into flexion. In the lower back, approximately 50% of flexion occurs at the hips, and 50% occurs at the lower spine.
