Spinal flexion loads the anterior aspect of the spinal disc, driving the nucleus pulposus posteriorly against the stretch-taut annular fibers. This can increase a bulging or herniated disc pathology. In today’s video, let’s have a look at Anterior and Posterior …
Sciatica is a condition in which the sciatic nerve is compressed, causing referral symptoms (often pain or numbness) into the lower extremity. The referral symptoms can be sensory and/or motor depending on whether sensory or motor neurons are compressed.
The authors concluded that little evidence was found supporting the hypothesis that extension McKenzie exercises affect disc fluid content.
Our brain produces sensations according to the credible believable evidence that is present, not just from the sensory information from that body part.
A pathologic disc can compress the sciatic nerve resulting in sciatica. Although any pathologic disc is potentially serious.
The “action” of a ligament is similar to that of an antagonist muscle. If either is tight/taut, it restricts motion to the opposite side.
The low back is defined by the lumbar spine, composed of 5 vertebrae, named L1-L5. The pelvis is defined by the bones of the pelvic girdle.
This blog post introduces and explains how the manual therapist can perform assessment and treatment for specific musculoskeletal conditions of the neck.
The danger with a disc bulge or herniation is that the disc can compress the spinal nerve within the intervertebral foramen, causing a pinched nerve.
Self care for a herniated disc: avoid postures/activities that increase stress upon the disc and stretching/strengthening the musculature around the disc.
Table 1 shows average healthy ranges of axial motion of the cervical spine (head and neck), from the atlanto-occipital joint through the C7-T1 joint.
The “action” of a ligament is similar to that of an antagonist muscle. If either is tight/taut, it restricts motion in the opposite direction.
The disc joint is a cartilaginous joint that is composed of outer fibers called the annulus fibrosus that encircle the inner nucleus pulposus.
Traction can be beneficial for the client/patient with a pathologic disc because it opens up the intervertebral foramina of the spine.
For a pathologic disc of the lumbar spine, the principle assessment test is straight leg raise (SLR). This can be performed actively or passively.
A herniated disc in the neck refers symptoms into the upper extremity. A herniated disc in the low back refers symptoms into the lower extremity (sciatica).
One cause of a pathologic disc (e.g., bulge, herniation) is excessive flexion postures, which drive the nucleus posteriorly against the taut annular fibers.
This article addresses the causes of the three different types of pathologic disc conditions: degenerated disc, bulging disc, and herniated disc.
