Many of us are using prone traction on our LBA with possibly slip dics. I use it in the same case with the decreased lordosis. Beattie PF et also wanted to check the outcomes after administration of a prone lumbar traction protocol. The study population consisted of total of 296 subjects with low back pain (LBP) and evidence of a degenerative and/or herniated intervertebral disk at 1 or more levels of the lumbar spine.

An 8-week course of prone lumbar traction, using the vertebral axial decompression (VAX-D) system, consisting of five 30-minute sessions a week for 4 weeks, followed by one 30-minute session a week for 4 additional weeks.
Roland-Morris Disability Questionnaire (RMDQ) were completed at preintervention, discharge (within 2 weeks of the last visit), and at 30 days and 180 days after discharge.

A total of 250 (84.4%) subjects completed the treatment protocol. On the 30-day follow-up, 247 (83.4%) subjects were available; on the 180-day follow-up, data were available for 241 (81.4%) subjects. We noted significant improvements for all postintervention outcome scores when compared with preintervention scores (P<.01).

How ever the authors are vary cautious about generalizing the result. They have stated “Causal relationships between these outcomes and the intervention should not be made until further study is performed using randomized comparison groups”
