Chiropractic View on Functional Spinal Instability in Low Back Pain

Bony restraint from facet joint orientation and ligamentous support are the major contributors to the passive stability of the lumbar intervertebral segments. However, these segments are unstable upon movement of the spine in the absence of dynamic neuromuscular control. A combination of dynamic muscular forces and passive ligamentous support are required to provide stability and movements of the spine for activities of daily living and sports activity. Spinal instability has been reported in some cases of spondylolisthesis which involves the forward slippage of the spinal segment. The presentation of spinal instability in these cases includes hypermobility or increased displacement or range of motion. Learn more about spondylolisthesis:

There are two major muscle groups in the lower back, local and global muscles, which should be working together to provide stability and mobility of the lumbar spine. Global muscles are large, dynamic, phasic muscles that connect the pelvic to the rib cage which generates torque movements and general trunk stabilization. Rectus abdominus, external oblique and upper part of lumbar iliocostalis are considered as global muscles.

Local postural, tonic muscles are attaching directly to the lumbar vertebrae and are the major contributors to the lumbar segmental stability. Lumbar multifidus, psoas muscle, quadratus lumborum, lumbar parts of iliocostalis and longissimus, transversus abdominis, the diaphragm, and the posterior fibers of the internal oblique are a few examples of the local muscles in the lower back. These muscles are important to maintain the spinal stability during movement of the trunk.
