Clinical Studies on the Effectiveness of Spinal
Twenty patients presenting with low back pain averaging approximately 5 years in duration were prospectively enrolled in a 6-week course of 20 motorized spinal decompression treatments via the DRX9000™ (Axiom Worldwide, Tampa, Fla). Two patients withdrew for protocol violations. For the remaining 18 patients, the baseline median verbal pain intensity score on an 11-point scale (0 = no pain; 10 = worst possible pain) decreased from 7 (25th to 75th percentile = 5–7) to 0 (25th to 75th percentile = 0–1) at study conclusion at Week 6 (P < .0001). No device-related adverse events occurred. Overall, 16 of 18 patients reported clinically significant pain improvement after noninvasive spinal decompression.

Lipson, in a 2004 paper in the New
England Journal of Medicine states that 151,000 spinal fusions are done each
year in the US. He advocates restraint because of the complications and
typically modest benefits associated with surgery. The end result of
surgery can be reduced mobility, stiffness, and continuing pain - "failed

"Decompression therapy, addresses both
primary and secondary causes of low back and referred leg pain. We thus
submit that decompression therapy should be considered first, before the
patient undergoes a surgical procedure which permanently alters the anatomy and
function of the affected lumbar spine segment."

"We consider decompression therapy to be
a primary treatment modality for low back pain associated with lumbar disc
herniation at single or multiple levels, degerative disc disease, facet
arthropathy, and decreased spine mobility. We believe that post-surgical
patients with persistent pain or "failed back syndrome" should bot be
considered candidates for further surgery until a reasonable trial of decompression
has been tried."
