Do you think hanging upside down to relieve back pain is unusual, or a new-age approach? Reconsider your perceptions. Spinal inversion probably goes back to the dawn of documented human medical care.
We know that inversion has been used at least since 400 B.C., when Hippocrates, the father of western medicine, first observed a patient have his knees and ankles tied to a ladder to be hoisted upside down for a dose of what has come to be known as inversion therapy.
The Greek theories on inversion are still valid, but today there is a much easier way to relieve the back pain than having your family and friends hoist you with ropes. The process is called spinal inversion therapy, and it can be the natural way to a better back and a better body.
Inversion-traction and Tissue Movement Studies
The journal – Spine: 1 May 1998 – Volume 23 – Issue 9 – pp 1061-1063
Study Design. Experimental study of 30 patients diagnosed with low back pain resulting from lumbar disc herniation, disc degeneration, and segmental instability. Patients underwent gravitational traction, and widening of the intervertebral space and posterior facets was measured on x-rays. This same procedure was performed with a group of 30 healthy individuals.
Objectives. To determine the effect of gravitational traction on the widening of the intervertebral space and the other vertebral structures in patients with low back pain and in healthy individuals.
Summary of Background Data. Gravitational traction is performed by suspending the patient in a hanging, upright position for an extended period of time. (inversion)
Methods. A specially designed apparatus was used to apply gravitational traction. Before and after inversion x-rays were obtained to study the changes in the L2-L3, L3-L4, L4-L5, and L5-S1 intervertebral spaces. Other data was also collected.
Results. Inversion-Distraction/traction created more than 3 mm of increased intervertebral disc space in subjects.
Conclusion. Spinal gravitational traction (inversion) had a very measurable effect on intervertebral space and was found to be an effective method to distract lumbar vertebrae.

3) Nosse, L.: Inverted Spinal Traction. Arch Physical Med Rehabil 59: 367-370, Aug 78. Study found EMG activity (an indicator of muscle activity, which tends to be greater with pain) declined 35 percent within the first 10 seconds of inversion
4) Nachemson, Alf, et al: Intravertebral Dynamic Pressure Measurements in Lumbar Discs. 1970. The study measured internal disc pressure (in the 3rd lumbar disc) during a range of activities, including standing, sitting, bending and vertical and traction. The study results identified that a traction load equal to sixty percent of body weight was sufficient to reduce the internal disc pressure to zero. This suggests that pain related to intradiscal pressure can be relieved by inversion.
5) Sheffield, F.: Adaptation of Tilt Table for Lumbar Traction. Arch Physical Med Rehabil 45: 469-472, 1964. One-hundred, seventy-five patients who were unable to work due to back pain were treated. After eight inversion treatments, 155 patients were able to return to their jobs full time. Study concluded that the main basis for improvement was the stretching of paraspinal vertebral muscles and ligaments and possibly the widening of intravertebral discs. The study found significant improvements in patients with a variety of diagnoses including spondylolisthesis, herniated discs, lumbar osteoarthritis with sciatica, and coccydynia.
6) Dimberg, L, et al: Effects of gravity-facilitated [spinal inverson] traction of the lumbar spine in persons with chronic low back pain at the workplace. One-hundred sixteen people were enrolled in a randomized controlled trial that lasted for 12 months. The study compared inversion trained subjects to a control group who did not perform inversion to asses the effect of gravity inversion on pain level and absenteeism due to low back pain. After 12 months of training program, the employees performing inversion 1 or 2 times per day decreased sick days due to back pain by 33 percent. Moreover, the average number of sick days used due to back pain fell by eight days per individual in the inversion group.
If you have some disc bulging or herniation, and you are not a surgical candidate or do not wish to proceed with surgery, many of you will markedly decrease your pain with inversion-traction.
Over half of people who perform spinal inversion regularly do so to relieve back pain. But, to discount inversion as simply a back pain remedy would be to ignore a wide range of benefits that can be easily achieved by a passive, or more active, inversion session.
Inversion represents the quiet side of fitness, helping your body to recover from the compressive effects of gravity and daily activities. Doctors, physical therapists and sports trainers recognize spinal inversion as a safe and effective form of therapy for the spine and weight-bearing joints. In fact, the US Army is evaluating including spinal inversion into its worldwide physical training.
Whatever your reason for inverting, inversion equipment provides a comfortable and easy method to turn your painful world upside down.
