Study Outcomes & Clinical Relevance: Forty-six of the 60 participants completed the program. At an average of 16 months after completion, 38 patients were available for follow-up while 8 patients could not be located or contacted. Of these 38 patients only three required surgery after completing the program.

In other words, patients who were informed they required back or neck surgery had a 92% chance of avoiding surgery with aggressive spinal strengthening on the MedX Medical Machines.
