My wife, a nurse practitioner, and I did a clinical study in 2004 and 2005 that included 92 of our patients who suffered primarily from rheumatoid arthritis, osteoarthritis, and fibromyalgia. The subjects did two daily pressure-therapy treatments for fourteen days. The results were significant. By the fourteenth day (the end of the study), 82% of the patients reported significant to total pain relief and increased quality of life because of this relief. Some of the participants purchased Rejuvenators, and are still using them with continued success.
