A Single Session of Spinal Decompression with Oscillation and Videofluoroscopy

Background: Computerized spinal decompression using the intervertebral differential dynamics (IDD) therapy protocol has achieved 86–92% positive results in reducing back pain. There are many causes of back pain, and one of the most common is a degenerative disc. The etiology of a degenerative disc is not completely understood, but it can be related to acute injuries, repetitive stress, nutrition, genetic factors, and oxidative stress1. Standard of care may include physical therapy or manipulation to introduce movement to the spinal vertebrae. IDD Therapy® uses a calculated, sinusoidal, logarithmic primary waveform to separate the spinal vertebrae. More recent studies have shown that the addition of a secondary waveform gives a significant increase in efficacy. We observed these effects on the spine during an IDD Therapy® session. Methods: Images of the intervertebral space were taken by videofluoroscopy during the IDD Therapy® session. Results: The expected separation of L5-S1 was achieved. We also noted the separation profile of the vertebrae was uniquely uniform despite the graduated pressures, particularly when the secondary oscillation waveform was introduced. L5-S1 separation was 1 mm in size, and the anterior–posterior correlation was significant (p<0.05). Conclusion: Active oscillatory signaling introduced during the high-tension period of treatment may lead to more compliant muscle re-education and thus enhanced uniform separation of the vertebrae. We believe that IDD Therapy® using Accu-Spina® may achieve 92% positive results because the secondary oscillatory signal induces mechanotransduction of mechanical stimuli into electrochemical activity at the cellular level. Further research will lead to greater confidence and further exploration of mechanotransduction in intradiscal cellular tissues.
