I was injured from this drx9000 machine. I was promised I would be healed and back to my running, swimming and hiking by the end of my 28 treatments. I was lied to and ignored when I started getting worse. As a result of using this treatment I have rotator cuff tears, occipital headaches and weakness and numbness down both arms! These chiropractors should not be allowed to practice and keep their liscense! They strap you in and leave you on these tables that malfunction and cause jerking.
