Dr. Li states that he was motivated to write his paper in response to mine for which I did not use a vibrator2. It is difficult to take the vibrator seriously. With no consideration of the physical situation involved in solid objects falling through a small fluid-filled, curved canal, Li and other authors have used different vibrators as available. The most interesting aspect of Li's paper is the untreated control group, NONE of whom improved. In contrast, the literature indicates that the majority of patients with BPV improve Spontaneously.
Different authors use different time frames and descriptions, making direct comparisons difficult.
I have no reason to believe that Dr. Li's findings are not sincere, yet clearly, there is a problem. Perhaps we are not looking at the same disease. Perhaps some other reason will explain the differences. We must try to resolve this discrepancy. Time and further reports will tell.
