What motions can the spine do?

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 motions can be performed by the spine?

The spine has 4 main motions—forward bending, backward bending, sidebending, and rotation. These motions can also be coupled. For instance, you can have forward bending with rotation or backward bending with sidebending.

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 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 are 3 jobs of the spine?

The three main functions of the spine are to:

  • Protect the spinal cord, nerve roots and several of the body’s internal organs.
  • Provide structural support and balance to maintain an upright posture.
  • Enable flexible motion.

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 normal flexion of the lumbar spine?

Lumbar Spine Range of Motion:

Normal
Flexion 60
Extension 25
Left Lat Flex 25
Right Lat Flex 25

What part of the spine has the most rotation?

Rotation is greatest at the specialized atlantoaxial articulations, and to a lesser degree in the cervical and lumbar spine.

Why is movement limited in the lumbar spine?

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. The total range of rotation in the lumbar spine is therefore very limited, although not completely zero.

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.
