What is normal lumbar flexion ROM?
Low Back Ranges of Motion
The lumbar spine has five vertebrae and connects the spine to the pelvis. Normal lumbar ranges of motion include 60 degrees of flexion, 25 degrees of extension, and 25 degrees of lateral, or side, bending.
How much can the spine flex?
Spinal flexion might be largely unavoidable.
We see between 45-52 degrees of flexion. This is comparable to what we saw in the Potvin and McGill (1991) paper that first looked at shear values in stooped versus neutral postures. Even in those lifters who tried to maintain neutral we say more than 40 degrees of flexion.
How much can the lumbar spine flex?
(note: it is a hard to give a definitive answer for this because what is reported is the absolute amount of spinal flexion for a motion segment rather than how much it can move maximally). In the lumbar spine this seems to be around 15-18 degrees for the entire spine motion.
Where does 75% of back flexion occur?
About 75% of all spinal flexion below the neck occurs in the lumbar spine, and about 70% of all lumbar flexion occurs at the lumbosacral joint. Any muscle with vertical or oblique fibers that connects the thorax with the pelvis assists in flexion of the trunk.
What motion 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).
Why is spinal flexion bad?
It is NOT dangerous to flex the lumbar spine, as it is not dangerous to flex the hips, the elbows or the fingers. Sure it is true that people often injure themselves while bending or lifting. Of course flexing is also often painful in those who have low back pain but that does not mean that lumbar flexion is “bad”.
Can planking damage your back?
PLANKING STRESSES THE LUMBAR SPINE. If you don’t have a near perfect pattern of activity and strength in your deepest core, planking puts heaps of stress on the lumbar spine. We treat people all the time who have found that the more planking they do the more back pain they get.
Is twisting the spine bad?
The short answer; yes and no. Twisting of the lumbar spine (the low back) is dangerous and can be quite harmful. The most common and a significant issue can be a disc tear. In order to avoid this, rotation of the mid back or thoracic spine and hips is better for you.
Is loaded spinal flexion bad?
As the spine flexes (bends forward, flattens, or rounds), several tissues are at risk of injury. Muscles provide support for the spine as it begins to flex; however, as the spine approaches full flexion, the support responsibilities shift away from the muscles and onto the intervertebral discs and ligaments.
Should you flex your spine?
Spinal Flexion and Spinal Stenosis
Generally, getting your spine into a flexed position helps relieves the pain and cramping associated with neurogenic claudication. It’s always wise to consult with your healthcare provider and physical therapist for the best positions and exercises given your individual condition.
What is flexion of spine?
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.
Why is movement limited in the lumbar spine?
Because of the more sagittal slope of the articular surfaces, very little rotation takes place at the four upper lumbar levels. More distally, at the lumbosacral level, the joint line has a more coronal plane, which makes rotational movements potentially possible, but these are limited by the iliolumbar ligaments.
Which of the following is the most common mechanism for lower back strain?
Disc herniation is the most common cause, and inflammation of the affected nerve rather than its compression is the most common pathophysiological process.
