There is a substantial body of evidence, from disparate sources, that vestibular stimulation, particularly of the otolith organs, can modulate metabolism and thus energy homeostasis. We have previously suggested that repeated otolith stimulation could be used to improve glycemic control in patients with type 2 diabetes mellitus (T2DM). Here we present double-blind pilot data from 30 Indian patients with T2DM who were randomized 1:1 to active and sham stimulation. All subjects received standard dietary advice. The 15 active patients used an electrical vestibular nerve stimulation device at up to 1mA, for about five hours a week over a three-month period. This technique has previously been shown to specifically activate the otolith organs. The mean HbA1c of the active group fell from 7.22% to 5.03% over the trial. Conversely, the mean HbA1c of the control group went from 7.75% to 7.36%. The marked fall in the HbA1c of the active group was greater than would be expected on the basis of weight loss alone. Given the relatively small number of participants and striking effect observed replication of these data is necessary.
