Extension of the spine: It is beneficial. It is harmful.
So what’s with extension for the spine?
Both are accurate: It’s beneficial. It is harmful. It’s the job of your Preston chiropractor to help you determine the role of extension for your Preston
back pain relief plan and Preston back pain control plan moving
past the existing episode of back pain.
Your Preston chiropractor at Chiropractic Associates is well experienced
in the effects – good and bad – of spinal extension and respects its role in spinal
health and motion.
Two of the spine’s most prominent curves –
the cervical and lumbar curves – are lordotic curves meaning they curve inwardly.
Flexion flattens these curves. Extension magnifies them. When a disc herniates
or bulges, it does so into the concavity of the curve and potentially presses
on the spinal nerves resulting in pain. Flexion usually
allows the disc bulge to get away from the
nerve. Extension often allows the disc bulge to compress
the nerves more. Chiropractic Associates wants to help decrease
painful situations like this!
75% of the flexion and extension movement in the low back occurs
at the L5-S1 level of the lumbar spine. 20% is at the
L4-L5 level. Therefore, 95% of flexion and extension of the lumbar spine happens
at these two lower disc levels. Here, degenerative disc disease (minor and more
advanced) happens most. In the cervical spine, C5-C6 is the spinal
level where most of the flexion occurs, and C4-C5 is where
most of the extension occurs. Preston chiropractic
patients need beneficial extension!
Chiropractic Associates respects extension and gets
how it may help and hurt. The extensor muscles in the
back weaken and degenerate just like discs do. (1)
Extension helps strengthen these muscles to support the spine. Extension is essential
for this when the spine is healthy enough to do extension. Extension to a painful spine may hurt. Why? In the cervical spine, flexion reduced disc
protrusion and maximizes the sagittal diameter of the vertebral
canal while extension increased the disc protrusion and narrowed the vertebral canal causing
stenosis. (2) In a degenerative lumbar spine with spinal stenosis, flexion opened
the vertebral canal and relieved pain while extension exacerbated
the stenosis and caused pain. (3) Chiropractic Associates knows
the key to eliciting the benefits of extension is in knowing
when to apply extension.
Preston CHIROPRACTIC USE OF EXTENSION
Preston chiropractic treatment incorporates
extension into the Preston chiropractic treatment plan for its benefits.
Cox® Technic applied to the cervical spine reduced
intradiscal pressures to as low as 502 mmHg (4) and to as low as -192 mmHg in
the lumbar spine. (5) Extension increased pressures in the lumbar
spine to 1250 mmHg (the most the transducer could measure).
(4) Dropping intradiscal pressures and back pain is what
Chiropractic Associates does for its Preston back pain

Doctor’s Podcast with Dr. Michael Johnson. He shares how he cared for
a patient whose back pain continues after multiple back
surgeries with flexion distraction which relieves her pain
as the table is flexed not extended.
