What is normal range of motion for 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°
What is the range of motion of the spine?
Thoracic and Lumbar Spine
Together, these vertebrae allow you to perform the major movements of the spine. The normal ROM for flexion or forward bending is 90 degrees. For extension, it’s approximately 30 degrees. The normal ROM for side bending and rotation is also 30 degrees.
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 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).
What are the 3 types of range of motion?
There are three basic types of range of motion: passive, active-assistive and active, defined by the whether, and to what degree, the patient can move the joint voluntarily.
Which part of the spine has the greatest range of motion?
The lumbar vertebrae are the largest and carry most of the body’s weight. This region allows more range of motion than the thoracic spine, but less than the cervical. Lumbar facet joints enable significant flexion and extension movement, but limits rotation.
What motion actions do the lumbar spine facets allow?
These joints allow flexion (bend forward), extension (bend backward), and twisting motion. Certain types of movement are restricted. The spine is made more stable due to the interlocking nature to adjacent vertebrae.
What is a lumbar rotation?
Lumbar rotation can be preformed in a supine position (lying on your back) keeping your upper extremity fixed and rotating your lower extremity. It is a twisting motion of your lower trunk area. … Many nerves innervate the muscles for spinal rotation.
What is normal lumbar extension?
Normal lumbar ranges of motion include 60 degrees of flexion, 25 degrees of extension, and 25 degrees of lateral, or side, bending.
