Promising research suggests that the
effects of Spinal Decompression Therapy
can be a long-lasting solution to
certain chronic back pain disorders.
Failure rates are relatively
low and studies suggest that completion of
prescribed treatments can reduce failure
rates from 32.9% to 3.9%.
Effect at the
level of the Herniated Disc:
The effects of
Spinal Decompression Therapy at the
level of the Interbertebral Disc is
thought to be a decrease in pressure,
thus creating a vacuum effect and
producing a negative interdiscal [within
the disc] pressure. This negative
interdiscal pressure is responsible for
a decrease in the size of the disc
herniation/bulge and a resultant
decrease in pain and pressure on the
nerve root.
The effects of
spinal decompression therapy on
intradiscal pressure (pressure within
the disc) was studied in the Journal of
Neurosurgery. The results indicated that
axial [spinal] decompression reduced the
intradiscal pressure significantly to
negative levels in the range of -100 to
-160 mm Hg.
An article in
the Journal of Neuroimaging reported
that a 90% reduction in disc herniation
size could be seen at the critical point
of nerve root impingement in 71% of
patients when pre-treatment and
post-treatment MRI examinations were
performed. Torn annulus repair is seen
in all patients.
Several other scientific articles have
reported a decrease in disc herniations/
protrusions, intradiscal ("within the
disc") pressure, an increase in joint
space and intervertebral ("between the
vertebrae") distance when measured by
x-ray, MRI, CT scan or epidurography.
Effect at the
level of the Nerve and Nerve Root:
It has been demonstrated that during
Spinal Decompression Therapy, the
vertebral bodies are distracted or
'separated'. This results in a negative
intradiscal pressure creating a 'vacuum
effect'. The resulting vacuum effect
creates a reduction of disc herniation
size which relieves, or takes 'pressure'
off, the spinal nerves. The effects of
Spinal Decompression Therapy at the
level of the nerve can be measured by
several Methods. DSSEP's (Dermatomal
Somatosensory Evoked Potentials) and CPT
(Current Perception Threshold) measure
nerve function and response, or the
"functioning/overall health" of a nerve.
